research the .toUpperCase() function

Code:

---

var a = "this is some text";
a.toUpperCase()
/* will give you -- THIS IS SOME TEXT */

---

to take that and make a function to use in a script

Code:

---

function convertToUpper(str, el)
{
    document.getElementById(el).value = str.toUpperCase();
}

---

Code:

---

<input type="text" name="_something_" id="_id_" value="" onblur="javascript:convertToUpper(this.value, '_id_')">

I don't think that's an anonymous function, but I could be wrong.

This certainly is an anonymous function (tested in FF 2 only, but may work in all or most modern browsers):

Code:

---

<input type="text" onblur="(function(){this.value = this.value.toUpperCase();}).apply(this);">

---

But I believe this also qualifies as anonymous:

Code:

---

<input type="text" onblur="this.value = this.value.toUpperCase();">

---

And I know it will work in any modern browser.

Though John certainly provides an aide.

I wonder what's the problem with CSS:

Code:

---

text-transform:uppercase;

---

...besides the obvious that the (real) value is not capitalized.
