从javascript捕获window.open

我把一个网页变成了一个html iframe，这个网页有一个javascript函数来打开链接，这个函数使用window.open方法来打开一个新窗口

---

我无法修改javascript函数（页面是用mapguide创建的），因此我希望在iframe之外捕获该调用，将新窗口的内容放入ajax模式框架，而不是打开新窗口，这可能吗？

我假设“mapguide”内容来自不同的域，而不是包含iframe的页面

如果是这种情况，您需要“代理”“mapguide”内容——即：您的iframe需要从服务器上的另一个脚本URL（本例中我假设为PHP）加载mapguide内容，服务器的代码将从“mapguide”软件的真正来源获取它。这一部分很简单，服务器端代码可能如下所示：

<? 
    $content = file_get_contents('http://mapguide.domain/path/to/contents');

    // alter content here

    print $content;
?>

iframe

src

属性应该指向服务器上包含该代码的PHP文件（而不是“mapguide”服务器）

如果“mapguide”内容包含HTML链接、加载CSS/JavaScript文件或进行AJAX调用，那么您需要让服务器端代码重写这些URL以引用回服务器。这一部分并不容易，实际上取决于“mapguide”JavaScript的复杂程度

因此，在上面的评论说

altercontent here

之后，您需要对

$content

中包含的HTML进行一些可怕的regexp替换（或解析并重新生成），目的是更改每个URL以通过“代理”PHP脚本，并从“mapguide”服务器上的适当位置加载

如果您成功地完成了所有这些，那么您的iframe将是来自与包含HTML页面相同域的服务器，因此外部页面的JavaScript将能够替换

窗口。打开iframe的
功能，以防止弹出，或者做任何您想做的事情，正如@jbabey在另一个回答中所说的那样

所有这些都假定“地图指南”内容没有用户协议和/或版权政策，禁止“刮”（自动复制）其（地图指南”内容的作者）内容
 虽然我一般不建议这样做，但您可以覆盖
窗口的定义。在iframe中打开
函数，假设您的页面和iframe位于同一个域中，以避免XSS安全错误

这是我一直在研究的一个类似的剪贴画。。。正确设置contentWindow是一件棘手的事情，但这可能提供了一些见解

//get a reference to the iframe DOM node
var node_iframe = document.getElementById("myiframe");

//get a reference to the iframe's window object
var win_iframe = node_iframe.contentWindow;

//override the iframe window's open method
win_iframe.open = function(strUrl,strName,strParams){

    /* create an object (to substitute for the window object) */
    var objWin = new Object;

    /* save the open arguments in case we need them somewhere */
    objWin.strUrl = strUrl;   
    objWin.strName = strName; 
    objWin.strParams = strParams; 

    /* create a blank HTML document object, so any HTML fragments that 
     * would otherwise be written to the popup, can be written to it instead */
    objWin.document = document.implementation.createHTMLDocument(); 

    /* save the object (and document) back in the parent window, so we 
     * can do stuff with it (this has an after-change event listener that 
     * pops a YUI Panel to act as a kind of popup) -- NOTE: the object in 
     * the parent window that we're saving this to has YUI Attribute installed
     * and listens to changes to the objPopupWindow attribute... when it 
     * gets changed by this .set() operation, it shows a YUI Panel. */
    parent.MyCustomClassObjectWithYUIAttributes.set('objPopupWindow', objWin); 

    /* return the object and all its members to whatever was trying to 
     * create a popup window */
    return objWin; 
    };//end override method definition

如果帧来自同一域和端口，您可以重写window.open函数来执行其他您想要的操作。我忘了提到我正在asp.net中制作网页，c#我尝试过这个，但在执行“frame.contentWindow.open”行后，我得到了：“frame.window为null或不是对象”；我在InternetExplorer8上运行这个，这是我的代码：var d=document.getElementById（“ifr”）//如果（d）{var ifropen=d.contentWindow.open；d.contentWindow.open=function（url、windowName、windowFeatures）{alert（windowFeatures）；return orgOpen（url、windowName、windowFeatures）；}d.window.open（“）；}@NatyBizz将新函数分配给
d.contentWindow.open
，调用
d.window.open
时，您缺少一个
；
。
var frame = document.getElementById('myFrame');

if (frame) {
    frame.contentWindow.open = function (url, windowName, windowFeatures) {
        // do whatever you want here (e.g. open an ajax modal frame)
    };
}

//get a reference to the iframe DOM node
var node_iframe = document.getElementById("myiframe");

//get a reference to the iframe's window object
var win_iframe = node_iframe.contentWindow;

//override the iframe window's open method
win_iframe.open = function(strUrl,strName,strParams){

    /* create an object (to substitute for the window object) */
    var objWin = new Object;

    /* save the open arguments in case we need them somewhere */
    objWin.strUrl = strUrl;   
    objWin.strName = strName; 
    objWin.strParams = strParams; 

    /* create a blank HTML document object, so any HTML fragments that 
     * would otherwise be written to the popup, can be written to it instead */
    objWin.document = document.implementation.createHTMLDocument(); 

    /* save the object (and document) back in the parent window, so we 
     * can do stuff with it (this has an after-change event listener that 
     * pops a YUI Panel to act as a kind of popup) -- NOTE: the object in 
     * the parent window that we're saving this to has YUI Attribute installed
     * and listens to changes to the objPopupWindow attribute... when it 
     * gets changed by this .set() operation, it shows a YUI Panel. */
    parent.MyCustomClassObjectWithYUIAttributes.set('objPopupWindow', objWin); 

    /* return the object and all its members to whatever was trying to 
     * create a popup window */
    return objWin; 
    };//end override method definition
