How to get the Tempdata in javascript?
提问by RJ Uy
I have this method in my Controller that saves the value in a Tempdata, as shown below.
我在我的控制器中有这个方法将值保存在一个临时数据中,如下所示。
public Boolean SaveSession(string id) {
TempData["CurrentTab"] = id;
return true;
}
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]"
现在在我的 javascript 中,我想获取该 TempData 中的值。但是当我提醒价值时,我得到了这个价值。“[对象 HTMLSpanElement]”
@{
if (TempData["CurrentTab"] != null){
@:alert("" + @TempData["CurrentTab"].ToString())
}
}
How can I get the string value of that Tempdata?
如何获取该 Tempdata 的字符串值?
Thanks
谢谢

The problem is that you're wrapping your TempDatavalue incorrectly.
问题是您TempData错误地包装了您的价值。
Assuming your idis my_span, the JavaScript output is:
假设你id是my_span,JavaScript 输出是:
alert("" + my_span)
When you probably want:
当您可能想要:
alert("my_span")
The reason you see [object HTMLSpanElement]is because the Browser tries to translate my_spaninto document.getElementById('my_span')(since it doesn't know of any other my_span) and you actually have such (span) element with that id.
您看到的原因[object HTMLSpanElement]是因为浏览器试图转换my_span为document.getElementById('my_span')(因为它不知道任何其他my_span),而您实际上拥有span具有该 ID 的此类 ( ) 元素。
Try:
尝试:
@{
if (TempData["CurrentTab"] != null){
@:alert('@(TempData["CurrentTab"])');
}
}
