客户端ajaxComplete调用生成无限iframe [英] Client-Side ajaxComplete Call Generating Infinite iframes

问题描述

好的，所以这是我的问题。我正在写一个Greasemonkey脚本在AJAXified网站上插入两个iframe，但是ajaxComplete被一个循环捕获并产生过多的iframe（有时是一个，有时是五个等等），gener。

Alright, so here is my issue. I'm writing a Greasemonkey script to insert two iframes on an AJAXified site, but ajaxComplete gets caught in a loop and generates an excess number of iframes (sometimes one, sometimes five, etc...), gener.

我已经完成了我的研究并且[我认为]我的问题是我没有正确地约束对文档的调用，但对此我不确定。我不确定你会怎么做比我已经有的不同。如果你们能指出我正确的方向，我将不胜感激。以下是有问题的代码：

I've done my research and [I think] my problem is that I'm not binding the call to the document properly, but of this I am unsure. I'm not sure how you would do it differently than I already have. If you guys could point me in the right direction I'd be grateful. Here is the offending code:

function OnLoadWidgets() {
    var tempSC = document.createElement("div");                                        
        tempSC.id = "SCWidget";
        tempSC.innerHTML = "..."
    document.getElementById("content-right").appendChild(tempSC);
    var tempMC = document.createElement("div");                                        
        tempMC.id = "MCWidget";
        tempMC.innerHTML = "..."
   document.getElementById("content-right").appendChild(tempMC);

}   

unsafeWindow.jQuery(document).ajaxComplete(function()
{   
    var existingSCPlayer = document.getElementById("SCWidget");                     
    if(typeof(existingPlayer) == "undefined")
    {
        OnLoadWidgets();
    }
});

也想利用这个机会感谢你们所有的辛勤工作。真的不能够感谢你。 stack == lifesaver

Also wanted to use this a chance to thank you guys for all your hard work. Can't thank you enough, really. stack == lifesaver

推荐答案

（1）目标网站 hypem.com ，使用自己的iframe，你的Greasemonkey脚本也将触发。

(1) The target site, hypem.com, uses its own iframes and your Greasemonkey script will fire on those also.

通过添加：

if (window.top != window.self)  //-- Don't run on frames or iframes.
    return;

靠近剧本顶部。

（2）代码中有一个变量名称拼写错误。 existingSCPlayer 与 existingPlayer 。

（3）优化重复检查以使其更具包容性。使用此代码：

(3) Refine the duplicate check to be a little more inclusive. Use this code:

unsafeWindow.jQuery (document).ajaxComplete ( function () {
    var existingSCPlayer = document.getElementById ("SCWidget");
    var existingMCPlayer = document.getElementById ("MCWidget");
    if ( ! existingSCPlayer  &&  ! existingMCPlayer) {
        OnLoadWidgets();
    }
} );
