Need help fixing return value in function..

**ShadowIce** · 05-17-2009, 01:25 PM

Hi all.

I have done some deep research on returning strings to an element id, and on for loops, but for some reason i cant seem to return the value of the text box i created. Instead, it returns a value of "NaN". The function that is returning "NaN" is "ztest()".

Here is the code as follows:

Code:

<script>
	<!--Hide from old browsers
	var x1 = 0;
	var x2 = 0;
	var num=4;
	function ztest(){
		if('document.test.forms.blah+x1.onClick'){
			if(document.getElementById('boxes').innerHTML != null || document.getElementById('boxes').innerHTML != ""){
				document.getElementById("zztest").innerHTML += document.test.forms.blah+x1.value;
			}else{
				alert('enter!');
			}
		}
	}
	function zsubmit(){
		if('document.forms.test.zzsubmit.onClick'){
			x2++;
		}
		alert(x2);
	}
	-->
</script>
<form name="test">
	<p align="Center">
		<script>
			<!--Hide from old browsers
			function addbox(){
				if('document.forms.test.add.onClick'){
					x1++;
				}
				document.getElementById('boxes').innerHTML += 'Name '+x1+': <input type="text" onClick="ztest();" name="blah'+x1+'"><br>n';
			}
			document.write('<span id="zztest" style="background-Color: #44CFFC; width: 400px; height: 50px;"></span><script>for(var x=1;x<=2;x++){document.write('<br>');}</script>n');
			document.write('<input type="button" name="add" value="Add box" onClick="addbox();">n');
			document.write('<input type="button" name="zzsubmit" onClick="zsubmit();" value="Submit"><br>n');
			document.write('<a href="javascript:window.opener=false, window.close('-1');">Exit</a><br>n');
			document.write('<span id="boxes" style="background-Color: #44CFFC; width: 400px; height: 25px;"></span><br>n');
			-->
		</script>
	</p>
</form>

I simply need the text box to return the value of the box to the element.

thanks!
