如何将onclick事件添加到动态生成的div中

Question

I have a number of div s in my HTML file that are dynamically generated. When I add the div s, I want to add an onclick event to each div .

Each div has a dynamic id . Using id , how can add an onclick handler?

Code that generates div s:

function createSlider(resp) {
    $.each(resp, function(key, val) {
        var item = "<div class='item' id="+val.id+">";

        item += "<h2>" + val.category + "</h2>";
        item += "<img src=" + val.image + " alt=" + val.title + ">";
        item += "</div>";

        $(".content-conveyor").append(item);
    });
}

Answer 1

You can apply the click function to the ID after you append it to the dom. So, after your $(".content-conveyor").append(item); line, add this:

$('#' + val.id).click(function() {
// Do stuff on click
});

Edit: After thinking about it more and considering @Nemoden's answer, you could also do it like this:

 function createSlider(resp) { $.each(resp, function(key, val) { var item = "<div class='item' id="+val.id+">"; item += "<h2>" + val.category + "</h2>"; item += "<img src=" + val.image + " alt=" + val.title + ">"; item += "</div>"; var $item = $(item).click(function() { // Add on click code here }); $(".content-conveyor").append($item); }); } 

This would attach the click callback without having to use the ID at all.

Answer 2

You could use the class name of the div for an event handler on all elements that match that class name.

$(".item").click(function() {
    //
 });

Answer 3

.live() is used to attach handlers to DOM elements that may not yet exist in the DOM. After $(".content-conveyor").append($item); add following code.

 $('#' + val.id).live(click,function() {
 // your code here
 });
