You must call display function after page load!
In script
(function($) {
function disply(){
/*YOUR DISPLAY CODE*/
};
$(function() {
disply();
});
}(jQuery));

I am trying to test the jQuery GET method, but what I am getting as result is completely insane. All I am trying to do is call a function from my controller with jQuery and then display the echoed value in a div within my view. Below is my code and finally a breakdown of the problem I am encountering.
Controller
public function generate_suggestions2() {
echo "James";
}
View views\suggestions_v.php
<body>
//This DIV is used a button to call the jQuery function
<div id="next_btn">
<p>Click here to display a name</p>
</div>
//In this div the value retrieved by the jQuery should be displayed
<div id="listB"></div>
//This is the function that calls the function within my controller
<script type="text/javascript">
$( "#next_btn" ).click(function() {
$.get("core/generate_suggestions2/",
function(data) {
$( "#listB" ).html(data);
});
});
</script> //For some reason I need to put the script at the end of the body. When it's in the head nothing happens when I click the button. Also something I do not understand.
</body>
Now the problem is that when I click the DIV next_btn it does NOT display the James in the DIV listB.
Instead it populates the DIV listB with my source code from my main view views\core_v.php
I have no idea how this is even remotely possible, so please if you have a clue or even better you know what I am doing wrong please tell me. I am trying to get this to work for the past three days without any success or progress :(
Try using this code in your view
<script type="text/javascript">
"$( "#next_btn" ).click(function() {
$.get("<?php echo site_url().'/core/generate_suggestions2';?>",
function(data) {
$( "#listB" ).html(data);
});
});"
</script>
Also delete the </script> tag just right before this block comment.
Regarding this comment you have:
//For some reason I need to put the script at the end of the body. When it's in the head nothing happens when I click the button. Also something I do not understand.
It is because the DOM is not yet fully loaded and Javascript executes its code when the browser has finished loading the DOM you are referring to. So you either have to put it after the DOM element you want to edit, like you do now or you could use $(document).ready(function(){
}
); .

This line is pretty strange:
</script><script type="text/javascript">
Try to delete first closing tag 'script' on it.
hi somebody pls explain to me why this code of mine doesn't work
$(document).ready(function()
{wireUpEvents();
});
function wireUpEvents()
{window.onbeforeunload = function()
{
window.location="link"; // on before unload i will run this link first.
}
}
when i refresh my page this code will run but it'll not go to link(window.location) before load however when i add alert like this
window.location="link"; alert("anything");
it'll go to my link before load. I like to eliminate that weird alert().
pls feel free to suggest any treatment with my code. thanks
try below code
window.onbeforeunload=testfunc;
function testfunc()
{
window.location="link";
}
Try this :
<script type="text/javascript">
$(window).bind('beforeunload', function() {
window.location="link";
}
);
</script>
I am implementing the search functionality through ajax jquery, though I am new in this. I have done that by using keyup event. Whenever type something, according to that letter(s), my searching list has been coming. But thing is that, I am not getting any record when refresh the page. If I search something then only I am getting record and if in that position I delete all the texts typed over the search field, then the correct list of records are coming, but not initially.
$("#search_term").keyup(function(e){
e.preventDefault();
ajax_search();
});
function ajax_search(){
$("#search_results").show();
var search_val=$("#search_term").val();
$.post("user-account-other.php", {search_term : search_val}, function(data){
if (data.length>0){
$("#search_results").html(data);
}
})
}
<div id="search_results"></div>
Now please tell me how can solve this issue.
Put ajax_search() funcion in on onload of document and also on blur of a text box element then it will work perfectly
Im not 100% sure what you're asking. I'd be happy to update this answer with some more information once I can understand the problem. I did, however, want to show you how to better streamline your code.
See: http://api.jquery.com/load/
$("#search_term").keyup(function(e){
e.preventDefault();
ajax_search();
});
function ajax_search(){
var url = "user-account-other.php?search_term=" + $("#search_term").val();
$("#search_results").load(url, function(){
//Ajax Load is Done
}).show();
}
I read this question, and I'm pretty sure it's 90% of what I need, but I'm after something more than just this, and my success formulating my query in Google has been less than stellar.
What I'd like to do
I have a form on a site that, when submitted, needs to connect with a database, and then the user needs to be apprised of the result. I'm trying to get the result page to load in a modal jQuery dialog instead of forcing a full page reload. At present, I'm just trying to create a jQuery dialog that replaces the contents of a <div> with the product of a PHP file. I know I will get the PHP file's execution result this way. That's what I'm after, but it currently is not working.
My code currently looks like this:
$(document).ready(function() {
$("#dialog").get('include.php', function(data) {
$("div#dialog").html(data);
});
});
And include.php is simply:
<?
echo "<h1>Loaded</h1>";
?>
When I load the page, the original contents of #dialog are still there. I have a strong suspicion that what I'm failing to grasp isn't major, but I've had bad luck finding the fix. I'm a web dev newbie. How do I wwebsite as on the internet?
You are calling get on a jQuery result. That'a a different method than $.get, the one you should be using:
$(document).ready(function() {
$.get('include.php', function(data) {
$("div#dialog").html(data);
});
});
i have been using Ajax call for the same purpose. So try this :
$(document).ready(function() {
$.ajax('include.php',
success : function(data) {
$("#dialog").html(data);
});
});
If you want to replace the entire contents of the #dialog DOM object with the HTML you load, then you probably want to use .load():
$(document).ready(function() {
$("#dialog").load('include.php', function(data) {
// no need to set the html here as .load() already does that
});
});
There's a great tutorial on IBM's website which walked me through a simple search/results list using jQuery,PHP and Ajax.
I was able to make it work and it's really cool.
One problem. I want the results to be hyperlinks and I can't get any java script to run on the results.
Here is the script I have (includes what was in the tutorial plus the additional script necessary to ovverride the hyperlink, click behavior):
<script type='text/javascript'>
$(document).ready(function(){
$("#search_results").slideUp();
$("#search_button").click(function(e){
e.preventDefault();
ajax_search();
});
$("#search_term").keyup(function(e){
e.preventDefault();
ajax_search();
});
$("a").click(ClickInterceptor);
});
function ajax_search(){
$("#search_results").show();
var search_val=$("#search_term").val();
$.post("./find.php", {search_term : search_val}, function(data){
if (data.length>0){
$("#search_results").html(data);
}
})
}
function ClickInterceptor(e)
{
window.alert("Hellow World!");
return false;
}
</script>
If i put the following html under the <body> tag:
this will work
That will display the alert window.
However, if I change the results to hyperlinks (found in find.php, listing 7 from the tutorial):
$string .= "".$row->name." - ";
It does not work.
Any idea on how to fix this?
The click function binds when it is run. You need to change it to a live binding.
$("a").live("click", ClickInterceptor);
Or you can just bind it when you update the search results by putting the following after $("#search_results").html(data):
$("#search_results a").click(ClickInterceptor);
The problem is pretty simple actually, $("a").click(ClickInterceptor); will only look for items that currently exist in the DOM. All you need to do is change that line to this:
$("a").live("click", ClickInterceptor);
I'd also advise taking the time to read more about jQuery's Events/live.
