How to code one jquery function for all AJAX links.

Question

I am using zend framework on windows. I want to implement ajax in my project first time. I searched for help and created a very simple ajax functionality.

IndexController.php

public function indexAction() {
}

public function oneAction() {
}

public function twoAction() {
}

index.phtml

<script type="text/javascript" src="js/jquery-1.4.2.js"></script>
<script type="text/javascript" src="js/AJAX.js"></script>

<a href='http://practice.dev/index/one' class='one'>One</a>
<a href='http://practice.dev/index/two' class='two'>Two</a>
<br /><br />
<div id="one">one.phtml content comes here</div>
<div id="two">two.phtml content comes here</div>

AJAX.js

jQuery(document).ready(function(){
    jQuery('.one').click(loadOne);
    jQuery('.two').click(loadTwo);
});

function loadOne(event) {

    event.preventDefault();

    jQuery.ajax({
        url: '/index/one',
        success: function( data ) {
                    jQuery('#one').html(data);
                    }
    });
}

function loadTwo(event) {

    event.preventDefault();

    jQuery.ajax({
        url: '/index/two',
        success: function( data ){
                    jQuery('#two').html(data);
                    }
    });
}

Above code is working and loading data of one.phtml and two.phtml in 'one' and 'two' DIVs respectively when its link is clicked. You can see that I have to create separate jquery function for each link and also have to add new class for each link tag.

What I want to do ?:

I want to use only one jquery function for all AJAX requests and don't want to hard code url and success attributes in that function.

When I add "AJAX" class to any link tag then it should load content using AJAX.

Thanks.

Answer 1

Maybe this:

function loadData(url, callback) {
    jQuery.ajax({url: url, success: callback});
}

loadData('/index/one', function( data ) {
    jQuery('#one').html(data);
})

loadData('/index/two', function( data ) {
    jQuery('#two').html(data);
})

To make this even more compact you could define the same callback for both and then have the handler decide which element the response data should be written to.

Answer 2

for simple loading of data in divs i would use the load method

HTML

<script type="text/javascript" src="js/jquery-1.4.2.js"></script>
<script type="text/javascript" src="js/AJAX.js"></script>

<a href='http://practice.dev/index/one' class='ajax' rel="one">One</a>
<a href='http://practice.dev/index/two' class='ajax' rel="two">Two</a>
<br /><br />
<div id="one">one.phtml content comes here</div>
<div id="two">two.phtml content comes here</div>

JS

jQuery(document).ready(function(){
    jQuery('.ajax').click(function(event){
       event.preventDefault();

       var target = '#' + jQuery(this).attr('rel');
       var href = jQuery(this).attr('href');
       jQuery( target ).load( href );

      });
});

Use a single class to identify all links that should use ajax calls instead of their normal use. And add a rel attribute to those links that will contain the id of the container div..

Compact version:

$(function(){
    $('.one').click(loadOne);
    $('.two').click(loadTwo);
});

function loadOne(event) {
    event.preventDefault();
    $('#one').load('/index/one');
}

function loadTwo(event) {
    event.preventDefault();
    $('#two').load('/index/two');
}
