[英]Sum Total of Row and Column in HTML Table using Javascript Excluding First and Last
[英]I need to find the total value of a column in a table, excluding the last row
我希望每當用戶對任何表單元格進行更改時,都能夠動態更新“新建”列下的總值。
DOM:
<div id='lc_adjustments'>
<table id='adjustments' cellspacing='0' width='550px' class='lc_nf' border='0'
cellpadding='0'>
<tbody>
<tr>
<td>
<table cellspacing='0' width='100%' class='lcb' border='0' cellpadding='0'>
<tr>
<td>
<table cellspacing='1' width='100%' class='ibody' border='0' cellpadding='0'>
<colgroup>
<col width='250px'></col>
<col width='150px'></col>
<col width='150px'></col>
</colgroup>
<tr class='header'>
<td>Item Name</td>
<td>Current Value</td>
<td>New Value</td>
</tr>
<tr onmouseover='high(this);' class='even' onmouseout='low(this);'>
<td class='cl'>Item number 1</td>
<td class='cl'>89.50</td>
<td class='cl'>
<input class='clsMandatoryReal' onchange='getTotal();' id='totalable'
value='89.50' size='25' type='text'>
</td>
</tr>
<tr onmouseover='high(this);' class='odd' onmouseout='low(this);'>
<td class='cl'>Item number 2</td>
<td class='cl'>69.70</td>
<td class='cl'>
<input class='clsMandatoryReal' onchange='getTotal();' id='totalable'
value='69.70' size='25' type='text'>
</td>
</tr>
<tr onmouseover='high(this);' style='font-weight: bold;' onmouseout='low(this);'
class='even'>
<td class='cl'>TOTAL STOCK MASS</td>
<td class='cl'>?</td>
<td class='cl'>?</td>
</tr>
</table>
</td>
</tr>
</table>
</td>
</tr>
</tbody>
</table>
我嘗試在jquery中執行此操作,但我的功能似乎無法正常工作:
function getTotal() {
var total = 0.0;
//iterate over each of the cells
$('table.ibody tbody tr').
children('td.cl').
children('input#totalable:not(:last)').each(function () {
total += $(this).text();
});
$('table.ibody tbody tr').
children('td.cl').
children('input#totalable:last)').value = total;
alert(total);
}
我願意使用jquery或javascript解決方案。 html是由Struts部分生成的,這意味着在大多數情況下,我對html class / id屬性無能為力。
這是一個jQuery替代品:
var total = 0;
//Iterate all td's in second column
$('#adjustments>tbody>tr>td:nth-child(2)').each( function(){
total += parseFloat($(this).text()) || 0;
});
alert(total)
最終這對我有用:
函數getTotal(){
var total = 0.0;
$('table.ibody tbody tr').
children('td.cl').
children('input#totalable').each(function(){
total += parseFloat(this.value);
});
$('table.ibody tbody tr').
children('td.cl').
children('div#totalable').html(total);
alert(total);
}
