Jquery Live Function

Question

我想让这个脚本作为LIVE（）函数运行。 请帮帮我！

 $(".img img").each(function() {
    $(this).cjObjectScaler({
   destElem: $(this).parent(),
      method: "fit"
    });
 });

cjObjectScaler脚本（在html标题中调用）是:(感谢Doug Jones）

(function ($) {
 jQuery.fn.imagesLoaded = function (callback) {
  var elems = this.filter('img'),
   len = elems.length;
  elems.bind('load', function () {
   if (--len <= 0) {
    callback.call(elems, this);
   }
  }).each(function () {
   // cached images don't fire load sometimes, so we reset src.
   if (this.complete || this.complete === undefined) {
    var src = this.src;
    // webkit hack from http://groups.google.com/group/jquery-dev/browse_thread/thread/eee6ab7b2da50e1f
    this.src = '#';
    this.src = src;
   }
  });
 };
})(jQuery);

.live()不起作用，您需要在需要时再次激活该功能，例如在您的$.ajax() success或complete回调中，.ajaxSuccess()，.ajaxComplete()中，或使用.livequery() plugin。

.live()侦听要冒泡的事件...添加新元素时没有任何交互，因此它不适合插件，至少不是基于事件触发的插件。< / p>
