Question

I am forming some java script code like this

 var url = '<%= Server.MapPath(".") %>' + '/Variablesvariable.txt';
 alert(url);
 xmlhttp.open("GET", url , true); //  url +'/Variables/variable.txt'
 xmlhttp.send();
//alert('<%= Server.MapPath(".") %> \Variablesvariable.txt')

whats wrong with this?

the URL don’t pass to method proper, at open method it get crashes, so am i forming the wrong URL, or some other way exist in the java script to concatenate it?

I see URL in add watch

it is forming like this

" url\"D:VisualStudio2010ProjectsWebSitesTinyEditor/Variablesvariable.txt\""

whats wrong?

Answer 1

<%= Server.MapPath(".") %>

This generates a physical path like c:somefolder. What you need to pass in is a url which is available on the web so something like /myfolder/Variablesvariable.txt.

So make it up like:

var url = '/myfolder/variables.txt';
alert(url);

Where you place the file variables.txt into a subfolder myfolder of your web application.

If you want to have it more dynamic you can do like this in your codebehind:

protected void Page_Load(object sender, EventArgs e)
{
    VariableUrl = ResolveUrl("~/Scripts/variables.txt");
}

public String VariableUrl { get; set; }

and in the markup:

var url = '<%= VariableUrl %>';
alert(url);

So what you put as parameter into the ResolveUrl method is entirely up to you.
