问题描述
我需要从父窗口访问子窗口元素.我已经在下面编写了示例代码片段.
I need to access child window elements from parent window. I have written the sample snippets below.
<html>
<head>
<title>Parent</title>
<style>
div{
float:left;
cursor:pointer;
}
</style>
<script type="text/javascript">
var SubpopUpWin="";
function Opennew(passedURL){
SubpopUpWin = window.open("popups.html", '_blank','toolbar=no,status=no,menubar=no,scrollbars=yes,resizable=yes,copyhistory=yes'); SubpopUpWin.document.getElementById("ifrm").src=passedURL;
SubpopUpWin.document.getElementById("ifrm_title").innerHTML=passedURL;
}
</script>
</head>
<body>
<div onclick="Opennew('http://www.google.com')">Google</div>
<div onclick="Opennew('http://www.yahoo.com')">Yahoo</div>
<div onclick="Opennew('http://www.bing.com')">Bing</div>
</body>
</html>
popups.html
<html>
<head>
<title>Child</title>
<style>
div{
float:left;
}
</style>
</head>
<body>
<div>
<div id="ifrm_title"></div>
<div style="margin-top:20px">
<iframe id="ifrm" src="" width="470" height="270" frameborder="0" style="margin-top: 34px" scrolling="no"></iframe>
</div>
</div>
</body>
</html>
在上面的代码中不起作用.甚至我也用过以下脚本.
In the above code is not working. Even I have used the below script also.
<script type="text/javascript">
var SubpopUpWin="";
function Opennew(passedURL){
SubpopUpWin = window.open("popups.html", '_blank','toolbar=no,status=no,menubar=no,scrollbars=yes,resizable=yes,copyhistory=yes');
SubpopUpWin.onload=function(){
SubpopUpWin.document.getElementById("ifrm").src=passedURL;
SubpopUpWin.document.getElementById("ifrm_title").innerHTML=passedURL;
}
}
</script>
上面的代码也不起作用.请分享您的建议/解决方案...
The above code also not working. Please share your sugestions/solutions...

推荐答案
我认为这是出于安全考虑.您可以改用这种方式:
I feel this is because of some security. You can try this way instead:
<html>
<head>
<title>Parent</title>
<style>
div {
float: left;
cursor: pointer;
}
</style>
<script type="text/javascript">
var SubpopUpWin = "";
var testUrl = "";
function Opennew(passedURL){
testUrl = passedURL;
SubpopUpWin = window.open("popups.htm", '_blank', 'toolbar=no,status=no,menubar=no,scrollbars=yes,resizable=yes,copyhistory=yes');
}
</script>
</head>
<body>
<div onclick="Opennew('http://www.google.com')">
Google
</div>
<div onclick="Opennew('http://www.yahoo.com')">
Yahoo
</div>
<div onclick="Opennew('http://www.bing.com')">
Bing
</div>
</body>
<html>
<head>
<title>Child</title>
<style>
div {
float: left;
}
</style>
</head>
<body>
<div>
<div id="ifrm_title">
</div>
<div style="margin-top:20px">
<iframe id="ifrm" src="" width="470" height="270" frameborder="0" style="margin-top: 34px" scrolling="no">
</iframe>
<script type="text/javascript">
document.getElementById("ifrm").src = window.opener.testUrl;
</script>
</div>
</div>
</body>
