如何获得的TempData在JavaScript? [英] How to get the Tempdata in javascript?
问题描述
我在我的控制器这种方法,在TempData的保存价值,如下图所示。
I have this method in my Controller that saves the value in a Tempdata, as shown below.
public Boolean SaveSession(string id) {
TempData["CurrentTab"] = id;
return true;
}
现在在我的JavaScript,我想在这TempData的值。但是,当我惊动了价值我得到这个值。 [对象HTMLSpanElement]
Now in my javascript, I want to get the value in that TempData. But when I alerted the value I got this value. "[object HTMLSpanElement]"
@{
if (TempData["CurrentTab"] != null){
@:alert("" + @TempData["CurrentTab"].ToString())
}
}
我怎样才能得到的TempData的字符串值?
How can I get the string value of that Tempdata?

推荐答案
的问题是,你是不正确的包装你的的TempData code>值。
The problem is that you're wrapping your TempData
value incorrectly.
假设你的 ID
是 my_span
,JavaScript的输出是:
Assuming your id
is my_span
, the JavaScript output is:
alert("" + my_span)
当你可能想:
alert("my_span")
您看到的原因 [对象HTMLSpanElement]
是因为浏览器尝试翻译 my_span
到的document.getElementById('my_span')
(因为它不知道任何其他的 my_span
),你居然有这样的(跨度
)元素与ID。
The reason you see [object HTMLSpanElement]
is because the Browser tries to translate my_span
into document.getElementById('my_span')
(since it doesn't know of any other my_span
) and you actually have such (span
) element with that id.
尝试:
@{
if (TempData["CurrentTab"] != null){
@:alert('@(TempData["CurrentTab"])');
}
}
