Convert String to ASCII Code?

[ernesto1989]

I'm trying to conver the String "Hopper" to ASCII code and this is what I have so far. Unfornately, it only displays the ASCII code for the last character or 114. And I would like to the code to display all the codes for every character. What am I doing wrong?

<script type="text/javascript">
function thisFunction() {
	var someString = "Hopper";
	var j;
	for(j = 0; j < someString.length; j++) {
		document.thisForm.clearText.value =  someString.charCodeAt(j);
	}
}
</script>

<form name="thisForm">
<input type="button" value="Pass Value" onclick="thisFunction()"/>
<br/>
<textarea rows="6" cols="30" name="clearText"></textarea>
</form>

document.thisForm.clearText.value +=  someString.charCodeAt(j);

It's because you are setting the value of the form field as just that one character as you loop the length of the string, so the last letter is the only ASCII code that will appear.

Try this:

document.thisForm.clearText.value +=  someString.charCodeAt(j);

This is shorthand for "field value equals itself plus additional data".

(Och! Fang beat me to it!)
