Client-Side Script Debugging
To test this, create a new web site project within Visual Studio .NET. Create a new web form/ASPX page,
or alternatively edit the Default.aspx page within the project. Remove the existing
declaration and everything contained within those tags, and replace it with the following code:
Test Script Debugging
function DoSomeWork()
{
var cntrl = document.getElementById(“txtInput”);
var number = cntrl.value;
number++;
}
var newValue = DoSomeMoreWork(number);
alert(“New Value = “ + newValue);
function DoSomeMoreWork(arg)
{
// Do some calculations
arg = arg * 2 + 32;
arg = arg + 18 / 2;
}
Debugging
Ensure that the newly created page is set as the Startup Page within Visual Studio by right-clicking on
the page with the mouse and selecting Set as Start Page.
Click the Play button, shown in Figure 13-6 (ensure that the active configuration is set to Debug), or
press F5 to launch the application in debug mode.
