This code helps to get the substring of the URL and then depending on the text, it assigns value to the       

control. However, the way it is done here is using a var 

Now, once the var is assigned the value when we click on the save button, it is not saved.

I want to issue a blur or focus for the control to which this var is referring to.

Could you please help me ?
