当我在文本框中输入金额时,它进入功能状态而不是循环工作。
我有一个表显示多个动态行。
行数仅计算函数中的count.value(javascript)
然后因为这个多行我只想要循环来增加价格(rec_qty * porate)
HTML
<?php
$table=mysql_query("SELECT * from purchase_order");
while($table1=mysql_fetch_array($table))
{
$i++;
<tr>
<td><input type="hidden" id="tatalrecord" value="<?php echo $i;?>"></td>
<td><input type="text" style="width:45px" class="form-control rec_qty" onkeyup="myFunction()" id="rec_qty"></td>
<td><input type="text" style="width:45px" class="form-control porate" onkeyup="myFunction()" id="porate"></td>
</tr>
<?php } ?>
</table>
JAVASCRIPT
function myFunction() {
var count = document.getElementById("tatalrecord");
var cn = count.value;
alert(count.value);
for(var i = 0; i < cn; ++i)
{
alert("hi");
var x = document.getElementById("rec_qty");
var y = document.getElementById("porate");
var z = x.value * y.value;
}
}
答案 0 :(得分:1)
function myFunction() {
var z = 0;
var count = document.getElementById("tatalrecord");
var cn = (count.value) ? parseInt(count.value) : 0;
alert(count.value);
for (var i = 0; i < cn; ++i)
{
var x = document.getElementById("rec_qty");
var y = document.getElementById("porate");
z = parseInt(x.value) * parseInt(y.value);
}
document.getElementById("total").value = z
}

嗨Shruti我试图缩短你的问题我已经创建了自己的表来假设表格行
希望这段代码可以帮助你......
<html>
<head>
<script type="text/javascript">
function myFunction() {
// var count = document.getElementById("tatalrecord");
//Total no of rows in your table
var cn = document.getElementById("tatalrecord").getElementsByTagName("tr").length;
console.log(cn);
for(var i = 0; i < cn; ++i)
{
console.log("hi");
alert('hi');
var x = document.getElementById("rec_qty");
var y = document.getElementById("porate");
var z = x.value * y.value;
console.log(z);
}
}
</script>
</head>
<body>
<form>
<table id="tatalrecord">
<tr><td>1</td></tr>
<tr><td>2</td></tr>
<tr><td>3</td></tr>
<tr><td>4</td></tr>
<tr><td>5</td></tr>
</table>
<input type="text" style="width:45px" class="form-control rec_qty" onkeyup="myFunction()" id="rec_qty">
<input type="text" style="width:45px" class="form-control porate" onkeyup="myFunction()" id="porate">
</form>
</body>
