我使用动态添加的域创建表单并想总结所有添加的域。到目前为止,我有以下的代码,但它只是总结的第一行:在动态添加的表单域中使用jquery.calculation.js
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Totals</title>
<script type="text/javascript" src="../js/jquery/jquery-1.6.2.js"></script>
<script type="text/javascript" src="../js/jquery/jquery.calculation.js"></script>
<script type="text/javascript">
//Sum
$(document).ready(
function(){
$('input[name^=reds]').sum("keyup", "#totalSumReds");
$("input[name^=blues]").sum("keyup", "#totalSumBlues");
}
);
</script>
<script type="text/javascript">
//Add/remove form fields
jQuery(function($){
$('#btnAdd').click(function(){
var num = $('.clonedInput').length;
var newNum = new Number(num + 1);
var newElem = $('#input' + num).clone().attr('id', 'input' + newNum);
newElem.children(':first').attr('id', 'name' + newNum).attr('reds', 'reds' + newNum);
$('#input' + num).after(newElem);
$('#btnDel').attr('disabled', false);
if (newNum == 5)
$('#btnAdd').attr('disabled', 'disabled');
});
$('#btnDel').click(function() {
var num = $('.clonedInput').length;
$('#input' + num).remove();
$('#btnAdd').attr('disabled', false);
if (num-1 == 1)
$('#btnDel').attr('disabled', 'disabled');
});
$('#btnDel').attr('disabled', 'disabled');
});
</script>
</head>
<body>
<form id="myForm">
<div id="input1" style="margin-bottom:4px;" class="clonedInput">
Numbers: <input type="text" name="reds"/>
<input type="text" name="blues" id="blues"/>
</div>
<div>
Totals: <input type="text" name="totalSumReds" id="totalSumReds" value="" size="2" readonly="readonly" />
<input type="text" name="totalSumBlues" id="totalSumBlues" value="" size="2" readonly="readonly" />
</div>
<div>
<input type="button" id="btnAdd" value="add line" />
<input type="button" id="btnDel" value="remove line" />
</div>
</form>
</body>
</html>
什么,我应该尝试修复它的任何想法?谢谢!
我不认为你应该使用这种类似的'变种newNum =新的Number(NUM + 1);' – elclanrs 2012-02-12 22:36:34
