Javascript跨窗口交互 [英] Javascript cross window interaction
问题描述
在链接被点击时，我有一个非常简单的JavaScript在文本区域写：
< head&
< script language =javascripttype =text / javascript>
function addtext（text）{document.form.textarea.value = document.form.textarea.value + = text;}
< / script>
< / head>
< body>
< form action =method =name =form>
< textarea name =textarearows =cols =wrap =wrap>< / textarea>
< / form>
< a href =javascript：addtext（'q'）;> q< / a>
< / body>
现在我想提高注意力。
我想要做的是在另一个窗口中的形式，当我单击链接，我写到另一个窗口中的textarea。
m不一定要求代码，因为我意识到这可能是相当复杂。
问题是从哪里开始，因为我没有一个线索！
（当我使用Javascript交叉窗口或跨域交互时，我真的没有什么有用的东西。）
所以任何帮助我可以得到，
好，我给你写了一个样例，你可以检查 http://jsfiddle.net/zzdAL/
$（document）.ready（function（）
{
popup = window.open（http://fiddle.jshell.net）;
$ ＃input1）。click（function（）{
try {
popup.document.window.alert（1）;
}
catch（e）{alert .message）;}
}）;
}
）;
它只在弹出窗口上运行一个警报，但你可以做任何你想要的弹出窗口，假设你有必要的权利（需要是我相信的相同的域）。
最简单的是在弹出窗口中编写一个函数并从开启者调用它。 / p>
I have this very simple Javascript to write on a text area when the link is clicked:
<head>
<script language="javascript" type="text/javascript">
function addtext(text) {document.form.textarea.value = document.form.textarea.value+= text;}
</script>
</head>
<body>
<form action="" method="" name="form">
<textarea name="textarea" rows="" cols="" wrap="wrap"></textarea>
</form>
<a href="javascript:addtext('q');">q</a>
</body>
Now I want to up the ante.
What I want to do is have the form in another another window, and that when I click the link, I writes to a textarea in another window.
I'm not necessarily asking for the code because I realize this might be quite complicated.
The question would be where to start, because I haven´t got a clue!! (when I Google cross window or cross domain interaction with Javascript I don't really get anything useful).
So any help I can get, libraries, plugins or whatever might guide me in the right direction is more than appreciated.
Ok, I wrote you a sample you can check at http://jsfiddle.net/zzdAL/
$(document).ready(function()
{
popup = window.open("http://fiddle.jshell.net");
$("#input1").click(function() {
try {
popup.document.window.alert(1);
}
catch (e) { alert(e.message); }
});
}
);
It only runs an alert on the popup, but you can do whatever you want with the popup, assuming you have the necessary rights (needs to be the same domain I believe).
The most simple is to write a function in your popup and call it from the opener.
