Getting value from function

melvinoyh · May 25th, 2006, 11:10 PM

for example this function get a value from a textbox and calculate and return the value to another textbox. this example can work.
-------------------------------------
<script type="text/javascript">

function chkBreakdown(){
myForm=document.brk

total=50*myForm.brkID.value
myForm.brk_total.value=total;
}

</script>

<html>
<body>
<form name="brk">
<input type="text" name="brkID" value="0" size="3" maxlength="3" onblur="chkBreakdown()">
<input type="text" name="brk_total">
</form>
</body>
</html>
------------------------------------------

now my problem is for example below:

Vector wp = new Vector();
Vector ln = new Vector();

<script type="text/javascript">

function chkBreakdown(wp,ln,la){
myForm=document.brk
total=wp+ln+la+*myForm.brkID<%=c%>.value <--is this correct or not?
myForm.brk_total.value=total;
}

</script>

<html>
<body>
<form name="brk">

<tr><td>LA no.</td><td>: <input type=text id="laNo" size=6 style="border:0" value='<%=la_no%>'> </td></tr>

<%for(int c=0; c<wp.size(); c++){%>
<td><input type="text" size=5 name="wp<%=c%>" value='<%=wp.elementAt(c)%>'></td>
<td><input type="text" size=4 name="ln<%=c%>" value='<%=ln.elementAt(c)%>'></td>
<td><input type="text" size=8 name="brkID<%=c%>" id="brkID" value='<%=brkID.elementAt(c)%>' onFocus="chkBreakdown('<%=wp.elementAt(c)%>','<%=l n.elementAt(c)%>','<%=la_no%>');"></td>
</form>
<input type="text" name="brk_total">
</body>
</html>

Hii Melvinoyh!!

1>>total=wp+ln+la+*myForm.brkID<%=c%>.value <--is this correct or not?
above one is incorrect
total=(wp+ln+la)*(myForm.brkID<%=c%>.value)
also take care about parseInt(number,radix)

2><%for(int c=0; c<wp.size(); c++){%>
where is correspoding "}" closing brackes

3>If brkID is part of for loop then
use document.getElementById,or getElementByName method to iterate all the brkID1,2....n field values.

4>Since your wp,ln,la values are also dynamic ,so pass the counter in ur case(<%=c%>) to the function and calculate the requried sum .

Hope this will help you

Cheers :)
