how to pass a "a href click" into jquery - php

i am trying to put a pagination page into jquery. example.html?id=foo&get=23
i would like to pass the get= into the jquery script so that i can change the page within the div instead of sending the link to the having the user see example.html?id=foo&get=23, they should only see example.html?id=foo. the rest is done in jquery.
<script >
$(document).ready(function()
{
$("#data").load("page.php?ht=<?php print $id; ?>&p=1" );
$("#next").click(function(){
var pageNum = this.id;
$("#content").load("page.php?ht=<?php print $id; ?>&p=" + pageNum, Hide_Load());
});
});
<div id="data">
page1
</div>

Why not modify the anchor
$('#next').attr("href","example.html?id=45");
After every click on the page?

you need something like this:
$(document).ready(function(){
$("#next").click(function(){
$.post('your_script_to_get_values.php',
{ page: "1" },
function(data) {
$('#content').html(data);
});
});
});

Make sure you use a live click handler, and not just a click handler, because you are creating the #next element after the page loads.
$("#next").live('click', function(){ //etc.
Documentation for .live()
It matches the current selector now and in the future (i.e. if the elements are created dynamically).

The simplest way would be with a session variable.

Code to update HTML link after one click?

I am looking for a code, which I can put inside a standard HTML href link - that, once the link is clicked, will immediately update a portion of the link in real-time.
Something like:
Example
Will at first print:
Example
And so after it being clicked once, it'll instantly change to:
Example
Anyone got anything simple up the sleeve for that?
Thanks!
First include JQuery
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js" ></script>
Give your link an id
<a id="link" href="http://example.com/page1/">Example</a>
Use the link in your JQuery code
$(document).ready(function() {
$(document).on("click", "#link", function() {
$(this).attr("href", "http://example.com/page1-clicked/");
});
});
edit
I you want to do the same with many links give your link a class
<a class="link" href="http://example.com/page1/">Example</a>
Then change the JQuery code to
$(document).ready(function() {
$(document).on("click", ".link", function() {
$(this).attr("href", "http://example.com/page1-clicked/");
});
});
using JQuery's one event handler to change the link only once:
$(function () {
$('a').one(function (event) {
var elem = $(this);
var before = elem.attr('href');
var after = before + '-clicked/';
elem.attr('href', after);
})
});

Reload div using jquery load function working only once and how to pass a variable

I have very limited knowledge with scripts so I hope you guys can help me with a simple solution to a small problem that I have...
I'm using the following jquery function to refresh a div with new content when a link is clicked
<script>
$(function() {
$("#myButton").click(function() {
$("#loaddiv").fadeOut('slow').load("reload.php").fadeIn("slow");
});
});
</script>
My problem is, I need to send 2 variables to the reload.php page to use in a mysql query (I have no idea how to accomplish that), also I need to make multiple links work with this function, at the moment I have multiples links with the same id and only the first link works so I guess I must associate different ids to the function in order for this to work, how can I do that?
here's the page where i'm using this: http://www.emulegion.info/teste/games/game.php
You may want to use document ready instead of function on your first line as this will make sure the code is not executed until the full page (and all elements) have loaded.
You can then use the callback functions of the fade and load to perform actions in a timely manner.
additional variables you can add after the .php, these can then be read in your reload.php file as $var1 = $_GET['var1'];
Do make sure to sanitize these though for security.
<script type="text/javascript">
// execute when document is ready
$(document).ready(function() {
// add click handler to your button
$("#myButton").click(function() {
// fade div out
$("#loaddiv").fadeOut('slow',function(){
// load new content
$("#loaddiv").load("reload.php?var1=foo&var2=bar",function(){
// content has finished loading, fade div in.
$("#loaddiv").fadeIn('slow');
}); // end load content
}); // end fade div out
}); // end add click to button
}); // end document ready
</script>
For different variables you could add a HTML5 style variable to your button.
<input type="button" id="myButton" data-var1="foo" data-var2="bar" />
You can retrieve this when the button is clicked:
// add click handler to your button
$("#myButton").click(function() {
// get vars to use
var var1 = $(this).data('var1');
var var2 = $(this).data('var2');
...
load("reload.php?var1="+var1+"&var2="+var2
if you have multiple buttons/links I would use class instead of id "myButton". that way you can apply the function to all buttons with the above script. Just replace "#myButton" for ".myButton"
First, you should use .on('click', function() or .live('click', function() to resolve your one click issue.
You'll want to do something like:
<script>
$(function() {
$("#myButton").on('click', function() {
var a = 'somthing';
var b = 'something_else';
$.post('url.php', {param1: a, param2: b}, function(data) {
//data = url.php response
if(data != '') {
$("#loaddiv").fadeOut('slow').html(data).fadeIn("slow");
}
});
});
});
</script>
Then you can just put var_dump($_POST); in url.php to find out what data is being sent.
Try creating a function that would accept parameters that you want.
Like:
$(document).ready(function(){
$('.link').click(function(){
reload(p1,p2);
});
});
function reload(param1, param2){
$("#loaddiv").fadeOut('slow').load("reload.php?param1="+param1+"&param2="+param2).fadeIn("slow");
}
But by doing the above code your reload.php should be using $GET. Also you need to use class names for your links instead of id.
<script type="text/javascript">
// execute when document is ready
**$(document).ready(function() {**
**$("#myButton").click(function() {**
**$("#loaddiv").fadeOut('slow',function(){**
**$("#loaddiv").load("reload.php?var1=foo&var2=bar",function(){**
// content has finished loading, fade div in.
$("#loaddiv").fadeIn('slow');
});
});
});
});
</script>
$("#myButton").click(function() {
// get vars to use
var var1 = $(this).data('var1');
var var2 = $(this).data('var2');

Jquery load dymanic content with parameter

I'm trying to load div content based on the a href being clicked and pass in a parameter. For example, Link 1
Clicking on Link 1 will pass value "3" to process.php, and return back the value "apple is good for you".
However, I can't seem to be able to pass the value without having a submit button. Anyway I can pass the parameter to another php file to process, and return the value?
$(document).ready(function(){
$("#testing a").live("click", function(evt){
var id= $(this).attr('id');
$.post("process.php", { id: id },
function(data) {
alert(data);
$('#result').load(data);
});
})
});
Below is my HTML
<div id="testing">
hello
</div>
<div id="result"></div>
Appreciate your help, thanks a lot!
You shouldn't be using numbers for id values. Instead, prefix them with a letter, or consider adding them to a data- atribute on the element.
Additionally, $.live() is deprecated, and we are encouraged to use $.on() from here on out for event delegation. I've gone ahead and handled this in the code below, but the id issue remains.
Lastly, $.load() and $.html() aren't the same. If you want to load data into an element, you don't call the load method (though the name could lead to that confusion).
// Short-hand version of $(document).ready();
$(function(){
// Handle anchor clicks on #testing
$("#testing").on("click", "a", function(e){
// Prevent links from sending us away
e.preventDefault();
// POST our anchor ID to process.php, and handle the response
$.post("process.php", { 'id': $(this).attr("id") }, function(data){
// Set the response as the HTML content of #result
$("#result").html(data);
});
});
});
From your process.php file, you might have something like the following:
$msg = array(
"...chirp chirp...",
"This is response number 1",
"And I am the second guy you'll see!",
"Apples are good for you!"
);
$num = $_POST["id"] || 0;
echo $msg[ $num ];

Using jQuery within http.open

I have a jquery function whichh looks like this:
<script type="text/javascript">
$(document).ready(function() {
$('a#id').click(function(e){
e.preventDefault();
var id = $(this).attr('pid');
var title = $(this).attr('ptitle');
$('#product_list').prepend('<input type="hidden" value="'+ id +'"/><div>'+ title +'</div>')
});
});
</script>
I have a javascript file which has this code here:
> http.open('get', 'livesearch.php?name='+searchq+'&nocache =
> '+nocache+'&type=bookings/products');
The livesearch.php file has the a element (which the jQuery is requesting) like this:
Add
However when I click on the a element the jQuery doesn't respond. Could any please help?
Thanks

Use either live or delegate to add the click event because the element is not present in the DOM at the time the event is bound.
$('#id').live('click', function(e){
alert('you clicked the id element' );
});

Getting Calendar on main page to switch months without refreshing page

I have a main page with lots of content, one piece of content is a small calendar.
For the Calendar I have a Previous month and next month link. What I want to do is switch between months without having to refresh the page.
<div id='cal_wrapper'>
<a href='main.php?month=$m&year=$y' class='selector'>Previous month</a>
<a href='main.php?month=$m&year=$y' class='selector'>Next month</a>
<?PHP
echo $calendar;
?>
</div>
Javascript is as follows:
<script type="text/javascript">
$(document).ready(function() {
$('#cal_wrapper a.selector').click(function(e){
$('#cal_wrapper').load( $(this).attr('href') );
e.preventDefault();
});
});
</script>
What is happening is when I click on either prev/next link the entire page is reloaded into the cal_wrapper div..??? I'm stuck.
Maybe try putting e.preventDefault() first, i.e.:
$('#cal_wrapper a.selector').click(function(e){
e.preventDefault();
$('#cal_wrapper').load( $(this).attr('href') );
});
If I understand your question right, I think you want $(this).attr('href') to refer to the href attribute of $('#cal_wrapper a.selector'). Instead what is happening, is that $(this), at that point, actually is referring to the $('#cal_wrapper') element, not the $("#cal_wrapper a.selector') element.
If this is correct, what you may want to do is store $('#cal_wrapper') in a temporary variable, i.e,
$('#cal_wrapper a.selector').click(function(e) {
var o = $(this);
$('#cal_wrapper').load($(o).attr('href'));
e.preventDefault();
});
