Javascript on ASP TextBox

Question

I dont undestand why, but my javascript doesnt work ... I've some textbox like these:

<asp:TextBox runat="server" Text='<%# Bind("SCAPULAIRE") %>' ID="txtScapulaire"/>

And i try to get the value of these textboxes. So i use javascript this way:

document.getElementById('<%=txtScapulaire.ClientID %>').value = 3;

But Visual studio tells me that "txtScapulaire is not declared". Maybe because of its protection. Do you have any idea why it isnt working ?

Thanks a lot !

@user3272798 - The problem I think is,you have your textbox inside any databound control like Gridview or Repeater control. In that case it won't work like this. — Rahul Singh
