I used the buttons to get the answer but now i need to multiply the cell 1 and cell2 values and need show the answer in the cell3 textbox when the onkeypress event occurs
but the thing is, it is showing the answer only in first occured cell3 textbox
I need to show the answer in that particualr ROW textbox
when this event fires it calls a function which is in javascript file
hope u understood my doubt
here is my code
test.php
<html>
<head>
<script src="/sample.js"></script>
<body>
<table id="myTable" border="1">
<?php
for($r=1;$r<=3;$r++)
{
$anscell='ans' . $r;
$txtname='txt' . $r;
$cal='cal' .$r;
echo'<tr>
<td id="'.$anscell.'">10</td>
<td><input type="text" name="'.$txtname.'" id="'.$txtname.'" value="" onkeypress="cell('.$r.')"></td>
<td><input type="text" name="'.$cal.'" id="'.$cal.'" ></td>
</tr>';
}
?>
</table>
</body>
</html>
JS file is this
// JavaScript Document
var xmlHttp
function cell(r)
{
var anscell = 'ans'+r;
var txtfield = 'txt'+r;
var cal='cal'+r;
if (document.getElementById(anscell) && document.getElementById(txtfield))
{
var x = parseInt(document.getElementById(anscell).innerHTML);
var y = parseInt(document.getElementById(txtfield).value);
}
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null)
{
alert ("Browser does not support HTTP Request")
return
}
var url="cal_total.php"
url=url+"?cqty="+y+"&cprice="+x
xmlHttp.onreadystatechange=stateChanged
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
}
function stateChanged()
{
var cal='cal'+r;
if (xmlHttp.readyState==4 ¦¦ xmlHttp.readyState=="complete")
{
document.getElementById("cal").innerHTML=xmlHttp.responseText
}
}
function GetXmlHttpObject()
{
var xmlHttp=null;
try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
//Internet Explorer
try
{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
}
return xmlHttp;
}
cal_total.php
<html>
<head>
</head>
<body>
<?php
$qty=$_GET['cqty'];
$price=$_GET['cprice'];
$tot=$qty*$price;
echo $tot;
?>
</body>
</html>
thanks
