如何使用javascript和/或jquery从父窗口访问iframes文档事件鼠标位置 [英] How can I access an iframes document event mouse position from the parent window using javascript and or jquery

问题描述

我在父窗口中有一个iframe，iframe src和父窗口位于同一个域中。为了保持iframe文档不受javascript限制，我希望能够在父窗口中使用一个函数来获取iframe中的鼠标位置。

I have an iframe inside of a parent window, with both the iframe src and the parent located in the same domain. In order to keep the iframe document clear of javascript I want to be able to use a function in the parent window to get the the mouse position inside the iframe.

我的尝试到目前为止，包括：

My attempts at this so far have included:

<iframe id="iframe1" src="test.html" style="position:relative; width:500px; height:500px"></iframe>
<div id="result" style="border:1px solid black"></div>

<script>
$(document).bind("mousemove", function(e){
    $("#result").html("x:" + e.pageX + ", y:" + e.pageY);
});

$("#iframe1").contents().find(document).bind("mousemove", function(e){
$("#result", window.parent.document).html("x:" + e.pageX + ", y:" + e.pageY);
});
</script>

第一个mousemove事件正常显示结果div中的鼠标位置，但是第二个事件（我试图绑定到iframe文档）没有给出任何响应。

The first mousemove event works correctly displaying the mouse position in the results div, but the second event (which I was attempting to bind to the iframe document) gives no response.​

推荐答案

此有效，但权限部分除外。

This works, except for the permissions part.

JS：

$(document).bind("mousemove", function(e) {
    $("#result").html("x:" + e.pageX + ", y:" + e.pageY);
});

$($("#iframe1").contents()[0], window).bind("mousemove", function(e) {
    $("#result").html("x:" + (e.pageX) + ", y:" + e.pageY);
});

问题在于 .find（） 。我只是使用内容返回的数组上的第一个索引，因为iframe应该只包含文档。

The problem was with .find(). I simply used the first index on the array returned by content, because an iframe is supposed to contain nothing but a document.
