I have a php page with jQuery, with range sliders.
When the sliders are changed the jQuery code sums the values.
I also want this code to be fired when the page is loaded. But it doesn't happen when I trigger the function inside $(window).load(function() {}); or directly in $(document).ready(function() {});.
Here's the jQuery code:
$(document).ready(function() {
$(window).load(function() {
countSilders();
});
function countSliders(){
var SliderValue = parseInt($("#slider0").val())+parseInt($("#slider1").val())+parseInt($("#slider2").val());
if (SliderValue==10)
$("#submit_next").button("enable");
else
$("#submit_next").button("disable");
$("#lblsum_scores").text(SliderValue+"/10");
}
$(document).on("change","#sliders", function(){
countSliders();
});
});
Try this:
// First define your function
function countSliders() {
var SliderValue = parseInt($("#slider0").val()) + parseInt($("#slider1").val()) + parseInt($("#slider2").val());
if (SliderValue == 10) $("#submit_next").button("enable");
else $("#submit_next").button("disable");
$("#lblsum_scores").text(SliderValue + "/10");
}
// Run on ready, don't use ready and then on load, that will never happen
// And i changed the on() to change()
$(document).ready(function(){
countSilders();
$("#sliders").change(function(){
countSliders();
});
});
You should be able to do:
function countSliders(){
...
}
$(document).ready(function() {
countSilders(); // fire it on load
// bind it to sliders
$(document).on("change","#sliders", function(){
countSliders();
});
});

I'm outputting several divs using php - each div has a different country name for the class.
I'm also outputting a variable using jquery which checks if content of a div has changed. That variable will also be a country name.
If the jquery variable matches a div class, I want that div to .show(), how can I do that?
This is my (horrible) attempt:
(function($) {
$(document).ready(function () {
$("#block1").bind("DOMSubtreeModified", function() {
message = $("#block1").html();
regiondiv = '.';
fullregion = regiondiv + message;
alert(fullregion);
if ($('.region-logos').hasClass(message)) {
$(fullregion).show();
} else {
$(fullregion).hide();
}
});
});
})(jQuery);
If I click on Canada for instance, it will show the .Canada div, but if I click on Spain after it, it's shows the .Spain div as well as the .Canada div. I.e once you click on more than one it just continues to show them all. It doesn't hide the divs if you haven't click on it.
var class = 'no-class';
$(document).ready(function () {
$("#block1").bind("DOMSubtreeModified", function() {
var regiondiv = '.';
var fullregion = regiondiv + class ;
$(".fullregion").hide();
class = $("#block1").html();
fullregion = regiondiv + class ;
$(".fullregion").show();
});
});
Not sure if I followed the question correctly. I assume you want to display a div if class of that div matches a variable in javascript. If so the you can try this:
(function($) {
$(document).ready(function () {
$("body").bind("DOMSubtreeModified", function() {
// Not sure how are you generating this jquery variable
var yourJqueryVariable;
// Check if class name exists
if ($(".yourJqueryVariable")[0]){
$(".yourJqueryVariable").show(); //or even $(".yourJqueryVariable").css('display','block');
}
});
});
})(jQuery);
(function($) {
$(document).ready(function () {
$("#block1").bind("DOMSubtreeModified", function() {
var message = $("#block1").html();
//ok so you have the variable to check
if($('.'+message).length > )) { //is there 1 or more of these classes in the DOM?
$('.'+message).each(function() { //there is, loop and show them all
$(this).show();
});
}
});
});
})(jQuery);
EDIT
Ok looking at your updated answer, assuming there are multiple .region-logos you need to perform your if else within a loop of those:
$('.region-logos').each(function() {
if($(this).hasClass(message)) {
$(fullregion).show();
}else {
$(fullregion).hide();
}
});
I am having name, email in content of a html page. i have to validate it on clicking continue button. and also the content in the content div has to change. how can i do both on clicking the continue button. help me with some suggestions. thanks.
am using the following code for changing div content.
<script>
$(document).ready(function () {
$("#button").click(function () {
$("#content").load("<?php echo base_url().'survey/categories' ?>");
});
});
$(document).ready(function () {
$("#button1").click(function () {
$("#content").load("<?php echo base_url().'survey/budget_overview' ?>");
});
});
</script>
As i understand your question, i think what you want is to do the two tasks at the same time on click of the button. So here's some sample code assuming this is what you want. If you have any doubts just ask. And i have added just sample Email Validation Using RegExp in JavaSript at the end of the code as a function.. Get the idea, Hope this helped you,,
//
$(document).ready(function() {
//Button1 Click
$("button").click(function(){
//initialize inputs here
var email =$("#email").val;
var input1=$("#input1").val;
//Validate Inputs Here
if(IsEmail(email)==true && input1!=""){
return true
}
else{
return false;
}
//Loading the first content after validating inputs
$("#content").load("<?php echo base_url().'survey/categories' ?>");
//To Trigger the other button
$('#button1').trigger('click');
});
//Button1 Trigger Will fire Click event
$("#button1").click(function () {
$("#content").load("<?php echo base_url().'survey/budget_overview' ?>");
});
});
//Email Validation In JavaScript
function IsEmail(email) {
var regex = /^([a-zA-Z0-9_\.\-\+])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
return regex.test(email);
}
I think the problem is with your syntax. You have to specify a file URL in the load method like this:
$(document).ready(function(){
$("form").submit(function(){
$("#content").load("myfile.php");
return false;
});
});
You can have a look on the load documentation.
I have this AJAX GET:
function edit(str){
ajax.onreadystatechange=function()
{
if (ajax.readyState==4 && ajax.status==200)
{
document.getElementById("editaircraftdialog").innerHTML=ajax.responseText;
$("#editaircraftdialog").dialog('open');
$("#loadingdialog").dialog('close');
}
}
ajax.open("GET","./edit_aircraft.php?icao="+str,true);
ajax.send();
$("#loadingdialog").dialog('open');
}
The JQuery code in edit_aircraft.php does not work. Here's an example:
<script>
$(function() {
$("#insertaircraft")
.button()
.click(function(event) {
});
});
</script>
I have had the same problem in the past and I cannot fix it.
You can not load JavaScript with innerHTML. It does not get evaluated.
Use jQuery to your advantage
function edit(str){
var loading = $("#loadingdialog").dialog('open');
var aircraft = $("#editaircraftdialog");
aircraft.load("./edit_aircraft.php?icao="+str, function(){
loading.dialog('close');
aircraft.dialog('open');
});
}
I'm using Twitter Bootstrap's Popover feature on a sidebar. The sidebar is fetched and reloads the content every 30 seconds. I'm suing XMLHttpRequest to reload the content of the sidebar by fetching a file called stats.php.
The following code is the "refresh" code which resides in the header of the page.
function onIndexLoad()
{
setInterval(onTimerCallback, 30000);
}
function onTimerCallback()
{
var request = new XMLHttpRequest();
request.onreadystatechange = function()
{
if (request.readyState == 4 && request.status == 200)
{
document.getElementById("stats").style.opacity = 0;
setTimeout(function() {
document.getElementById("stats").innerHTML = request.responseText;
document.getElementById("stats").style.opacity = 100;
}, 1000);
}
}
request.open("GET", "stats.php", true);
request.send();
}
The above code works flawlessly, however, after it reloads the #stats div, the popover no long does what it's supposed to - popup.
The popover code is in the stats.php in a foreach() loop because I have multiple popover scripts I need because there are multiple popovers on the sidebar.
Here's my popover code:
$(document).ready(function() {
$('a[rel=popover_$id]').popover({
placement:'right',
title:'$title',
content: $('#popover_content_$id').html()
});
});
The $id and $title are dynamic as they are pulled from the foreach() loop.
How can I fix it so after the div reloads, the popover function will reinitialize?
$("a[rel=popover_controller_$cid]").on({
mouseenter: function () {
$('a[rel=popover_$id]').popover({
placement:'right',
title:'$title',
content: $('#popover_content_$id').html()
});
}
});
I have also tried:
$("a[rel=popover_controller_$cid]").on("mouseover", function () {
$('a[rel=popover_$id]').popover({
placement:'right',
title:'$title',
content: $('#popover_content_$id').html()
});
});
.live is depreciated. use .on delegation
try something like this:
$('#stats').on("mouseenter", "a[rel=popover_controller_$cid]",function () {
$('a[rel=popover_$id]').popover({
placement:'right',
title:'$title',
content: $('#popover_content_$id').html()
});
});
This delegates the mouseenter event from #stats to a[rel=popover_controller_$cid] and because the event is delegated it will still fire when #stats contents are replaced.
be careful - you will keep initializing popover on each mouseover. that might be bad.
while you are at it - you should use jquery's ajax instead of native xhr. its easier and more cross browser.
$.get('stats.php', function(d){
$('#stats').html(d);
};
--
setInterval(function(){
$.get('stats.php', function(data) {
$('#stats').html(data);
});
}, 30000);
He guys,
Maybe you can help me, i need a code when the page is loaded a function (below)
function update() {
$('#animation').load('/Stream/readLevel');
}
needs to execute, when this action is complete (so the content of the page /Stream/readLevel has been fully loaded the function must be loaded again in a number of seconds (2 seconds).
How can i accomplish this?
Thanks in advance!
As you only want to reload after the contents has been fully loaded you have to set the timer in success callback of $.load function like following, otherwise it will send request to server every two seconds irrespect of if the previous ajax request has been completed or not.
function update() {
$('#animation').load('/Stream/readLevel',function(){
var timer = setTimeout(update,2000);
});
}
$(function(){
update();
});
you can do it like this.
$(function(){
update();
});
function update() {
$('#animation').load('/Stream/readLevel', function(){
alert("after two seconds of load");
setTimeout('update()', 2000);
});
}
<script>
function update() {
$("#animation").load('/Stream/readLevel',"",function(){
setTimeout(update,2000);
});
}
</script>
<body onload="update()">
// HTML CODE
</body>
Try
function update(){
$('#animation').load('/Stream/readLevel',function(){
setTimeout(update,2000); });
}
var c = 2;
function update() {
$('#animation').load('/Stream/readLevel');
}
function startTimer(){
if(c< 0){
c=2;
}
if(c==2){
update();
}
timer = setTimeout('startTimer()',1000);
c=c-1;
}
$(document).ready(function(){
startTimer();
});
