This is my code:
这是我的代码：
<script>
function popupTest(title) {
alert(title);
return false;
}
</script>
<a href="" onclick="return popupTest('This is 'some' "test" string')"><span>Recommend</span></a>
Using Firefox 4 I get the error:
使用 Firefox 4 我收到错误：
Error: missing ) after argument list
Source Code:
return popupTest('This is 'some' "test" string')
It's like it's decoding the HTML entities but I don't know why.
就像它正在解码 HTML 实体，但我不知道为什么。
Have also tried...
也试过...
<a href="" onclick="return popupTest('This is \'some\' \"test\" string')"><span>Recommend</span></a>
Which gives error:
这给出了错误：
Error: unterminated string literal
Source Code:

'is HTMLfor '. So for the first example the HTML is parsed and the JavaScript engine is passed:
'是HTML的'. 因此，对于第一个示例，解析 HTML 并传递 JavaScript 引擎：
return popupTest('This is 'some' "test" string')
… and the second 'terminates the string.
… 第二个'终止字符串。
On the other hand:
另一方面：
onclick="return popupTest('This is \'some\' \"test\" string')"
Is parsed as:
被解析为：
An onclick attribute with the value
return popupTest('This is \'some\' \followed by some invalid data.
带有值
return popupTest('This is \'some\' \后跟一些无效数据的 onclick 属性。
You need to deal with the JavaScript first:
您需要先处理 JavaScript：
return popupTest('This is \'some\' "test" string')
andthen escape it for HTML:
并且，然后逃逸它的HTML：
onclick="return popupTest('This is \'some\' "test" string')"
You would probably be better off using unobtrusive JavaScriptand binding the event handlers with JavaScript instead of using intrinsic event attributes.
您可能最好使用不引人注目的 JavaScript并使用JavaScript绑定事件处理程序，而不是使用内部事件属性。
