Question

简而言之，我的iframe加载了本地HTML页面并希望访问此页面的by click on them元素，例如all type of inputs，{{ 1}}，dropdown list等。

这是iframe标记内的HTML代码：

table

我将其加载到asp.net网络表单中：

<!DOCTYPE html>
<html id="bootbody">
    <head>
        <title>test2</title>
        <link href='bootstrap.min.css' type='text/css' rel='stylesheet' />
        <style>
            @media only screen and (max-width: 767px) and (min-width: 0) {
            .panel {
            height: auto !important;
            }
            }
        </style>
    </head>
    <body >
        <div id="testttt" class='container text-right'>

</html>

这是访问iframe内部元素的脚本代码：

<div id="frameWrapper">
                    <iframe id="frame" src="../HtmlHolder/TEST2.html">[ممکن است بدلیل تنظیمات پیکر بندی مرورگرتان ،قادر به مشاهده ی نمایشگر موبایل نباشید.لطفا مرورگر خود را تغییر دهید.]
                    </iframe>
                </div>

我使用上面的代码来查找iframe正文，但无法访问它的元素......

我谷歌它，但发现其他的东西，如<script> $(document).ready(function () { var frm = $("#frame").get(0); var doc = (frm.contentDocument ? frm.contentDocument : frm.contentWindow.document);//here is your document object var bdy = doc.body; alert(bdy); }); </script>或找到find element by class name不适合我。我该怎么做？非常感谢你。

specific element

Answer 1

试试这个

 jQuery(jQuery('[id="frame"]')[0].contentWindow.document.body).on('click', '*', function() {
   console.log("triggered !!");
   console.log(this.className); // class of element clicked
 });

Answer 2

你可以这样试试。

$(document).ready(function () {
    var frm = $("#frame").get(0);
    var doc = (frm.contentDocument ? frm.contentDocument : frm.contentWindow.document); //here is your document object
    var bdy = doc.body;
    $(bdy).on("click", "*", function (e) {
        console.log($(e.target).attr("class"));//To get class name
    });
});

Answer 3

如果有人遇到这些解决方案的问题，我能够使用John R解决方案，但不是使用$（文档）.ready我必须听取iframe负载。

像这样：

$("#frame").on('load', function(){
   var frm = $("#frame").get(0);
   var doc = (frm.contentDocument ? frm.contentDocument : frm.contentWindow.document); //here is your document object
   var bdy = doc.body;

   $(bdy).on("click", "*", function (e) {
       console.log($(e.target).attr("class"));//To get class name
   });
});

通过单击获取iframe中的元素类名称
