跨浏览器严重问题

[GavinCici521]

在IE下显示在firefox下却不显示报错如下：
[Exception... "'JavaScript component does not have a method named: "onLocationChange"' when calling method: [nsIWebProgressListener::onLocationChange]" nsresult: "0x80570030 (NS_ERROR_XPC_JSOBJECT_HAS_NO_FUNCTION_NAMED)" location: "JS frame :: file:///D:/Program%20Files/Firefox%20Plus/App/firefox/components/nsSessionStore.js :: sss_observe :: line 283" data: no]
file:///D:/Program%20Files/Firefox%20Plus/App/firefox/components/nsSessionStore.js
Line 283

283行的代码是： aSubject.addEventListener("load", function(aEvent) {


完整代码如下：

/**
   * Handle notifications
   */
  observe: function sss_observe(aSubject, aTopic, aData) {
    // for event listeners
    var _this = this;

    switch (aTopic) {
    case "domwindowopened": // catch new windows
      aSubject.addEventListener("load", function(aEvent) {
        aEvent.currentTarget.removeEventListener("load", arguments.callee, false);
        _this.onLoad(aEvent.currentTarget);
        }, false);
      break;
    case "domwindowclosed": // catch closed windows
      this.onClose(aSubject);
      break;

请问高手，什么原因，怎么解决？

firefox里没有addEventListener可以使用aSubject.attachEvent

楼上说反了吧，是ie没有吧

onLocationChange方法在哪里？很明显没有找到onLocationChange的定义啊！！！

不错是反了，onLocationChange在firefox里没有，你要找替代的方法。
