JavaScript错误：条件编译在MVC2查看关闭 [英] JavaScript Error: conditional compilation is turned off in MVC2 View

问题描述

我想呼吁点击JavaScript函数在MVC2查看页面。

 ＆LT;一的onclick =SelectBenefit（小于（％）= o.ba_Object_id％GT;，＆LT;％= o.ba_Object_ code％＆GT;）的href = ＃＆GT;选择＆LT; / A＆GT;
 

JavaScript函数

 函数SelectBenefit（ID，code）{
     警报（ID）;
     警报（code）;
 }
 

下面ba_Object_Id和code是从视图模型的值。如果我使用 SelectBenefit（小于（％）= o.ba_Object_id％GT;）以这种方式，其工作的罚款。但是，当我有两个PARAMATERS其not.I正在此错误：

 条件编译已关闭。
 

解决方案

我认为你需要把周围的第二个参数报价，如果它是一个字符串：

 ＆LT;一的onclick =SelectBenefit（小于（％）= o.ba_Object_id％＆gt;中'＆LT;％= o.ba_Object_ code％＆GT;'）的href =＃＆GT;选择＆LT; / A＆GT;
 

这是说你的参数需要适当EN $ C $的CD，我不会通过他们likse这一点。我将序列它们作为JSON对象，以确保一切正常。像这样的：

 ＆LT;一的onclick =SelectBenefit（小于％=新的JavaScriptSerializer（）序列化（新{ID = o.ba_Object_id，code = o.ba_Object_ code}里）％GT;）的href =＃＆GT;选择＆LT; / A＆GT;
 

然后SelectBenefit功能可能是这样的：

 函数SelectBenefit（利益）{
    警报（benefit.id）;
    警报（利益code）;
}
 

I am trying to call a JavaScript function on click in a MVC2 View Page.

 <a onclick=" SelectBenefit(<%=o.ba_Object_id %>,<%=o.ba_Object_Code %>)" href="#">Select</a>

JavaScript function

 function SelectBenefit(id,code) {
     alert(id);
     alert(code);
 }

Here ba_Object_Id and Code are the values from the ViewModel. If I use SelectBenefit(<%=o.ba_Object_id %>) in this way, its working fine. But when I have two paramaters its not.I am getting this error:

conditional compilation is turned off.

解决方案

I think that you need to put quotes around the second parameter if it is a string:

<a onclick=" SelectBenefit(<%=o.ba_Object_id %>, '<%=o.ba_Object_Code %>')" href="#">Select</a>

This being said your parameters need to be properly encoded and I wouldn't pass them likse this. I would serialize them as JSON object to ensure that everything is OK. Like this:

<a onclick="SelectBenefit(<%= new JavaScriptSerializer().Serialize(new { id = o.ba_Object_id, code = o.ba_Object_Code }) %>)" href="#">Select</a>

and then the SelectBenefit function might look like this:

function SelectBenefit(benefit) {
    alert(benefit.id);
    alert(benefit.code);
}
