Javascript File with Code <%= variable%>

Feb 19, 2020 06:11 AM|zequion|LINK

I have several .aspx pages that use the same javascript functions. These functions include code <%= variable%>. I want to pass these functions to a .js file but they are not displayed correctly with Visual Studio and also the functions are not executed.

// --------------
// .Aspx
// --------------
<head runat="server">    
   <script type="text/javascript" src="../js/Js_Common.js"></script>
</head>

<script language="javascript" type="text/javascript"> 
  var myvariable = fcn_variable();
</script>

// --------------
// Js_Common.js
// --------------
function fcn_variable()
{   var myvariable = null;
    myvariable = '<%=Form_Label.ClientID%>';
    return myvariable;
}

JavaScript files are text files, not part of the ASPX page, and not processed by the framework.

Use standard programming techniques . The simplest is passing the id to the function.
```
function fcn_variable(id)
{   var myvariable = id;
    return myvariable;
}
```
In the aspx page.
```
<script language="javascript" type="text/javascript"> 
  var myvariable = fcn_variable('<%=Form_Label.ClientID%>');
</script>
```
