Convert lowercase letter to upper case in javascript

rated 0 times [ 134] [ 4] / answers: 1 / hits: 60351 / 15 Years ago, mon, march 1, 2010, 12:00:00

I have a code that will convert lower case letters to uppercase but it works only with IE and not in Crome or Firefox.

function ChangeToUpper()

  {         

            key = window.event.which || window.event.keyCode;



            if ((key > 0x60) && (key < 0x7B))

            window.event.keyCode = key-0x20;

  }







<asp:TextBox ID=txtJobId runat=server MaxLength=10 onKeypress=ChangeToUpper();></asp:TextBox>

Even I tried with

document.getElementById(txtJobId).value=document.getElementById(txtJobId).value.toUpperCase();

onBlur event of the textbox

What should I do to make it work in all browsers?

Thanks

<script type=text/javascript>

    function ChangeCase(elem)

    {

        elem.value = elem.value.toUpperCase();

    }

</script>

<input onblur=ChangeCase(this); type=text id=txt1 />

separate javascript from your HTML

window.onload = function(){

        var textBx = document.getElementById ( txt1 );



        textBx.onblur = function() {

            this.value = this.value.toUpperCase();

        };

    };



<asp:TextBox ID=txt1 runat=server></asp:TextBox>

If the textbox is inside a naming container then use something like this

var textBx = document.getElementById (<%= txt1.ClientID %>);



            textBx.onblur = function() {

                this.value = this.value.toUpperCase();

            };)
