OnKeyPress Not called + JS

[sonia.sardana]

 <asp:TextBox ID="TextBox1" runat="server" onKeyPress='return maxLength(this,"30");'></asp:TextBox>

function maxLength(field,maxChars)
 {
 alert('onKeyPress');
       if(field.value.length >= maxChars) {
          event.returnValue=false; 
          alert("more than " +maxChars + " chars");
          return false;
       }

 }

When I Press any Character , maxLength function is not called,WHy SO?

maxLength is a property of the Text Object. Browsers are assuming you want to access that property not call a function.

Since Javascript is case sensitive, changing the function name to MaxLength or maxlength will work.

agreed
change the name of the function

to add to what brucevde and avrail wrote, you need some kind of javascript debugger (firefox firebug is a very good one) when you work with javascript.

i use IE8 Developer tool,
and you also should try Chrome Developer Tools it is perfect

Did you get a solution to your problem? If so, can you remember to mark your thread as resolved?
