How do you automatically set text box to Uppercase?

Issue

I am using the following style attribute to set the user input to uppercase so that when the user starts typing in the text box for example railway, then it should be altered to capital letters like RAILWAY without the user having to press the Caps-lock button.

This is the code I am using for the input:

<input type = "text" class = "normal" name = "Name" size = "20" maxlength = "20"> <img src="../images/tickmark.gif" border="0" style='text-transform:uppercase'/>

But I am not getting the desired output by using this attribute.

Solution

You've put the style attribute on the <img> tag, instead of the <input>.

It is also not a good idea to have the spaces between the attribute name and the value...

<input type="text" class="normal" 
       name="Name" size="20" maxlength="20" 
       style="text-transform:uppercase" /> 
<img src="../images/tickmark.gif" border="0" />

Please note this transformation is purely visual, and does not change the text that is sent in POST.

NOTE: If you want to set the actual input value to uppercase and ensure that the text submitted by the form is in uppercase, you can use the following code:

<input oninput="this.value = this.value.toUpperCase()" />
