带有点击的jQuery load（）动态内容被加载次数被触发

Question

I load content via jQuery load() but for each time I load a given page, the clicks on the pages gets fired multiple times. Why??

Se the fiddle here: http://jsfiddle.net/ZUZ3L/ph3tH/2/

Answer 1

Simply put your click hander outsie of load :

$(document).ready(function() {
    function loadContent() {
        $(".ajaxContainer").load("http://fiddle.jshell.net/ #actions", function() {
            alert("Done");                
        });
    }

    $(".load").click(loadContent);
    loadContent();
});​

Each time you load content, you execute this line:

$(".load").click(loadContent);

which adds a new event handler to the list of event handlers to execute whenever .load is clicked. You execute your function three times, now you have three identical handlers all triggering for each click.

Answer 3

because you are calling the function 2 times, try this:

$(document).ready(function() {
    function loadContent() {
        $(".ajaxContainer").load("http://fiddle.jshell.net/ #actions", function() {
            alert("Done");
        });
    }
    loadContent();
    $(".load").click(loadContent);

});

It's because you're adding the click event multiple times.

Every time your code runs, the click function is re-defined. When a click is redefined it won't replace the previous one, but instead will be added to the stack to be executed each time the "click" event occurs. This is applied to all events in jQuery.

As you are loading via AJAX the vars and events in the document are still persisted. Meaning that you are just adding layer on top of layer of function calls to be executed each time you run your ajax call
