I want that whenever my twilio call disconnects, the page should refresh itself automatically and a div that exists in different file should open. Here is my code
Twilio.Device.disconnect(function (conn) {
window.location.reload();
$('.dhxwin_active').show();
});
I think it is possible using querystring URL Like:
Twilio.Device.disconnect(function (conn) {
window.location = window.location.href + "?r=refresh"; // Get the URL Paramerter "r" according your requirement.
window.location.reload();
});
When page refresh you have got "r" value for URL
var refresh = '<?php echo $_REQUEST['r'] ;?>';
if(refresh == 'refresh') {
$('.dhxwin_active').show();
}
Please correct me if i am wrong

I've started using ajax requests recently. I am making a mobile web application where I am to the request for data on PHP side server script. The javascript function is to automatically execute when the user navigates to the page. But the script seems not to run until I refresh the page, here is my javascript code.
<script>
$( document ).ready(function(){
Date.prototype.yyyymmdd = function() {
var yyyy = this.getFullYear().toString();
var mm = (this.getMonth()+1).toString();
var dd = this.getDate().toString();
return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};
function requestContent() {
var date = new Date();
$.ajax({
type:'POST',
url:'php/app/adminTimeline.php',
data:{
date: date.yyyymmdd()
},
success: function(data) {
if (data == '') {
alert("No data found!");
} else {
// $("#loading_spinner").css({"display":"none"});
$('#timeline-content').prepend(data);
}
},
error: function(data) {
// $("#loading_spinner").css({"display":"none"});
alert("Something went Wrong!");
}
});
}
window.onload = requestContent();
});
</script>
The document.onready method and window.onload the method seems not to be working too.
Ps: I have the Jquery library linked in the header too.
Code included inside $( document ).ready() will only run once the page Document Object Model (DOM) is ready for JavaScript code to execute.
https://learn.jquery.com/using-jquery-core/document-ready/
Also you're calling requestContent()
window.onload must be function, not returning value.
$(document).ready(function(){
// here you ajax
}
https://jsfiddle.net/cqfq5on5/1/
The code window.onload=requestContent(); will execute when the window loads, not necessarily when the entire document has loaded.
However where you create the date object, uses this, which executes after the document is fully loaded
$(document).ready(function(){
//Code
});
This means, that the POST request will be made once the window loads, which is before the document is fully loaded, thus, that date object will not exist until the page is refreshed, at which point the Javascript was likely cached. Also another answer (#sagid) pointed out, window.onload cannot be a returning value but must be a function.
i.e.
window.onload=function(){
//Code
};
This means, your solution is to change window.onload=requestContent(); to
$(document).ready(function(){
requestContent();
});
Good luck!
I'm using this jQuery code to submit a dynamic form :
$('#formsite').on('submit', function (e) {
//prevent the default submithandling
e.preventDefault();
//send the data of 'this' (the matched form) to yourURL
$.post('inc/siteform.php', $(this).serialize());
});
but this method only sends the data to the PHP file. I want also that it redirects me to there, as an ordinary PHP POST submission.
How can I do it?
Here is the full testing site: http://edge-americas.com/control/main.html
UPDATE:
Using the method JQuery redirects me but it doesn't send the formdata at the same time so I can't use $_POST[] variables:
$('#formsite').on('submit', function (e) {
//prevent the default submithandling
e.preventDefault();
//send the data of 'this' (the matched form) to yourURL
$.post('inc/siteform.php', $(this).serialize(),function(response){
window.location = "inc/siteform.php";
});
});
Is there any other way to keep using jquery and solve it?
You can also use window.location.replace() and pass in the URL of where you want to be redirected as a paramter.
Location.replace() for more information on the method.
Javascript works perfectly for this:
window.location.href = "URL";
Or as Andy pointed out if you want users to go back without issues simply drop the .
window.location = "URL";
You can redirect or refresh page after succcess or server answer. For example:
$.ajax({
url:"?show=ajax_request&action=add_offer",
type:"POST",
data: {var_to_send : somevar},
dataType: "json",
success: function(answer){
if ( answer.result == 'success' )
{
location.reload(); // refresh the page
}
else if ( answer.result == 'error' )
{
window.location.href = "http://google.com"; // redirect to another page
}
}
});
I have the message-block in the header of my site. When a user clicks "close msg", the message should disapear and can't be seen during current user session.
So I decided to use jQuery Ajax:
$('#lang-msg .close').on('click', function(event) {
event.preventDefault();
$.ajax({
url:"remlmsg.php",
type:"POST",
data:"id=2,myajaxquery=true ",
success:function(html){
console.log(html);
$('#lang-msg').fadeOut(300,function() {
$(this).remove();
})
}
})
})
And in remlmsg.php I have only code, which defines new session variable:
$_SESSION['langmsg'] = 'hide';
echo $_SESSION['langmsg'];
In the header.php file I check if $_SESSION['langmsg'] is undefined.
if (!isset($_SESSION['langmsg'])) {
if ($sLanguage == 'ru') {
echo '<script type="text/javascript">
$( function() {
showLangMessage("en");
})
</script>';
}
}
And it says always true! But when I print request data in ajax function it displays 'hide'.
Explain to me, please, where I did mistake.
P.S.
Tested on local server (latest WAMP)
You need to have session_start() declared first. Otherwise you'll only edit a local variable that isn't stored anywhere.
Actually the problem you're having is that ajax calls will have a different session id, which has to do with the headers sent/received by both sides.
Try generating some javascript with PHP like:
var phpSessionId='<?=session_id()?>';
then in your remlmsg.php add this to the very top:
if(isset($_POST['session-id'])) session_id($_POST['session-id']);
session_start();
Finally in your ajax call use:
data:"id=2,myajaxquery=true,session-id=" + phpSessionId,
That should solve your problem.
I am submitting some data to my database then reloading the same page as the user was just on, I was wondering if there is a way to remember the scroll position the user was just on?
I realized that I had missed the important part of submitting, so, I decided to tweak the code to store the cookie on click event instead of the original way of storing it while scrolling.
Here's a jquery way of doing it:
jsfiddle ( Just add /show at the end of the url if you want to view it outside the frames )
Very importantly, you'll need the jquery cookie plugin.
jQuery:
// When document is ready...
$(document).ready(function() {
// If cookie is set, scroll to the position saved in the cookie.
if ( $.cookie("scroll") !== null ) {
$(document).scrollTop( $.cookie("scroll") );
}
// When a button is clicked...
$('#submit').on("click", function() {
// Set a cookie that holds the scroll position.
$.cookie("scroll", $(document).scrollTop() );
});
});
Here's still the code from the original answer:
jsfiddle
jQuery:
// When document is ready...
$(document).ready(function() {
// If cookie is set, scroll to the position saved in the cookie.
if ( $.cookie("scroll") !== null ) {
$(document).scrollTop( $.cookie("scroll") );
}
// When scrolling happens....
$(window).on("scroll", function() {
// Set a cookie that holds the scroll position.
$.cookie("scroll", $(document).scrollTop() );
});
});
#Cody's answer reminded me of something important.
I only made it to check and scroll to the position vertically.
(1) Solution 1:
First, get the scroll position by JavaScript when clicking the submit button.
Second, include this scroll position value in the data submitted to PHP page.
Third, PHP code should write back this value into generated HTML as a JS variable:
<script>
var Scroll_Pos = <?php echo $Scroll_Pos; ?>;
</script>
Fourth, use JS to scroll to position specified by the JS variable 'Scroll_Pos'
(2) Solution 2:
Save the position in cookie, then use JS to scroll to the saved position when page reloaded.
Store the position in an hidden field.
<form id="myform">
<!--Bunch of inputs-->
</form>
than with jQuery store the scrollTop and scrollLeft
$("form#myform").submit(function(){
$(this).append("<input type='hidden' name='scrollTop' value='"+$(document).scrollTop()+"'>");
$(this).append("<input type='hidden' name='scrollLeft' value='"+$(document).scrollLeft()+"'>");
});
Than on next reload do a redirect or print them with PHP
$(document).ready(function(){
<?php
if(isset($_REQUEST["scrollTop"]) && isset($_REQUEST["scrollLeft"]))
echo "window.scrollTo(".$_REQUEST["scrollLeft"].",".$_REQUEST["scrollTop"].")";
?>
});
Well, if you use _targets in your code you can save that.
Or, you can do an ajax request to get the window.height.
document.body.offsetHeight;
Then drop them back, give the variable to javascript and move the page for them.
To Remember Scroll all pages Use this code
$(document).ready(function (e) {
let UrlsObj = localStorage.getItem('rememberScroll');
let ParseUrlsObj = JSON.parse(UrlsObj);
let windowUrl = window.location.href;
if (ParseUrlsObj == null) {
return false;
}
ParseUrlsObj.forEach(function (el) {
if (el.url === windowUrl) {
let getPos = el.scroll;
$(window).scrollTop(getPos);
}
});
});
function RememberScrollPage(scrollPos) {
let UrlsObj = localStorage.getItem('rememberScroll');
let urlsArr = JSON.parse(UrlsObj);
if (urlsArr == null) {
urlsArr = [];
}
if (urlsArr.length == 0) {
urlsArr = [];
}
let urlWindow = window.location.href;
let urlScroll = scrollPos;
let urlObj = {url: urlWindow, scroll: scrollPos};
let matchedUrl = false;
let matchedIndex = 0;
if (urlsArr.length != 0) {
urlsArr.forEach(function (el, index) {
if (el.url === urlWindow) {
matchedUrl = true;
matchedIndex = index;
}
});
if (matchedUrl === true) {
urlsArr[matchedIndex].scroll = urlScroll;
} else {
urlsArr.push(urlObj);
}
} else {
urlsArr.push(urlObj);
}
localStorage.setItem('rememberScroll', JSON.stringify(urlsArr));
}
$(window).scroll(function (event) {
let topScroll = $(window).scrollTop();
console.log('Scrolling', topScroll);
RememberScrollPage(topScroll);
});
I had major problems with cookie javascript libraries, most cookie libraries could not load fast enough before i needed to scroll in the onload event. so I went for the modern html5 browser way of handling this. it stores the last scroll position in the client web browser itself, and then on reload of the page reads the setting from the browser back to the last scroll position.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
if (localStorage.getItem("my_app_name_here-quote-scroll") != null) {
$(window).scrollTop(localStorage.getItem("my_app_name_here-quote-scroll"));
}
$(window).on("scroll", function() {
localStorage.setItem("my_app_name_here-quote-scroll", $(window).scrollTop());
});
});
</script>
I tackle this via using window.pageYOffset . I saved value using event listener or you can directly call window.pageYOffset. In my case I required listener so it is something like this:
window.addEventListener('scroll', function() {
document.getElementById('showScroll').innerHTML = window.pageYOffset + 'px';
})
And I save latest scroll position in localstorage. So when next time user comes I just check if any scroll value available via localstorage if yes then scroll via window.scrollTo(0,myScrollPos)
sessionStorage.setItem("VScroll", $(document).scrollTop());
var scroll_y = sessionStorage.getItem("VScroll");
setTimeout(function() {
$(document).scrollTop(scroll_y);
}, 300);
I'm validating a form using jQuery and against a database using PHP-MySQL. The AJAX call is successful but the current page(A) is not redirected to page(B) after successful validation. But if i refresh the page, the page(B) is loaded. That is, the call is successful but jQuery is not redirecting.
<script language="javascript">
$(document).ready(function()
{
$("#login_form").submit(function()
{
//remove all the class add the messagebox classes and start fading
$("#msg").text('Checking....').fadeIn(1000);
//check the username exists or not from ajax
$.post("signin_check.php",{ loginid:$('#username').val(),pswd:$('#password').val() }, function(data)
{
if(data=='yes') //if correct login detail
{
$("#msg").fadeTo(200,0.1,function() //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).text('Logging in.....').fadeTo(900,1,
function(){
//redirect to secure page
document.location = "/pawn/selectdomain.php";
});
});
}
else
{
$("#msg").fadeTo(200,0.1,function() //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).text('Incorrect login details !!').fadeTo(900,1);
});
}
});
return false; //not to post the form physically
});
//now call the ajax also focus move from
$("#password").blur(function()
{
$("#login_form").trigger('submit');
});
});
</script>
I also tried replacing document.location with window.location and window.location.href and window.location.replace(....) but even they dont work. Someone please help.
the problem must be one of these 2 or both:
1) The data that ajax returns is not equal to 'yes'
2)ajax is not successful and it has error
please check that if the ajax is successful and then return value is equal to 'yes'
