jQuery脚本在Firefox和Internet Explorer上返回新窗口 [英] jQuery script returns new window on Firefox and Internet Explorer
问题描述
我有一个页面上的元素切换按钮，当我点击它，我可以看到脚本运行和切换元素，但是然后我得到一个新的窗口与JS对象返回[我猜..] 。它只是一个空白的窗口与我的HREF的网址，它说 [对象对象]
在铬的罚款，但ie和Firefox做到这一点。
他们这样做的方式是
$ p $ < a href =javascript：jQuery（'＃thatDude'）。肘节（）;>点击< / A>
< div id =thatDude> blah< / div>
更奇怪的部分是，我也有这个是我的脚本文件$ b $ （）。
$ pre $ j $ j $ ;
}）;
当我点击时 - 它在任何地方都能正常工作... [是啊我知道我应该改变生活委托=]]
有人知道最新怎么回事？
im使用jquery 1.6 [但是1.4.4也一样..]
非常感谢
发生什么事是脚本在 javascript： URI中的返回值，如果返回值不是void，被视为HTML并被解析。除了没有实现该功能的WebKit（下面提到一个例外）。在你的情况下，我假设jQuery的 toggle（）返回一个实际的值，这个值不是未定义的，这个值被当作一个字符串来解析为HTML。
您可以在IE，Firefox和Opera这个简单的测试用例中看到这种行为：
< a href =javascript：< h1>一些文字< / h1>'>点击我< / a>
在WebKit浏览器中完全失败，但这在WebKit中起作用，因为它们专用于一个代码路径：
< iframe src =javascript：< h1>一些文字< / h1>'>< /的iframe>
如果你想确保脚本的返回值是无效的，把 void （0）在脚本的最后。
i have this toggle button for an element on my page, and when i click it, i can see the script runs and toggles the element, but then i get a new window with the JS object returned [i guess..]. it just a blank window with a url of my href and it says [object Object]
in chrome its fine, but ie and firefox do this.
they way i do this is
<a href="javascript:jQuery('#thatDude').toggle();">click</a>
<div id="thatDude">blah</div>
the even stranger part is that i also have this is my script file
jQuery('.someBtn').live('click', function() {
jQuery('#someForm').toggle();
});
and when i click that - it works fine anywhere... [yeah i know i should change live to delegate =] ]
does anyone know whats going on? im using jquery 1.6 [but 1.4.4 does the same..]
thanks so much
What's going on is that the return value of the script in a javascript: URI, if that return value is not void, is treated as HTML and parsed as such. Except in WebKit, which doesn't implement that feature (with one exception mentioned below). In your case, I assume that jQuery's toggle() returns an actual value that's not undefined, and that value is treated as a string to be parsed as HTML.
You can see the behavior in this simple testcase in IE and Firefox and Opera:
<a href="javascript:'<h1>some text</h1>'">Click me</a>
This totally fails in WebKit browsers, though this does work in WebKit because they special-hack one codepath:
<iframe src="javascript:'<h1>some text</h1>'"></iframe>
If you want to make sure your script's return value is void, put void(0) at the end of the script.
