jQuery easyUI datagrid 增加求和统计行的实现代码
在datagrid的onLoadSuccess事件增加代码处理。
<style type="text/css">
.subtotal { font-weight: bold; }/*合计单元格样式*/
</style>
<script type="text/javascript">
function onLoadSuccess() {
//添加“合计”列
$('#table').datagrid('appendRow', {
Saler: '<span class="subtotal">合计</span>',
TotalOrderCount: '<span class="subtotal">' + compute("TotalOrderCount") + '</span>',
TotalOrderMoney: '<span class="subtotal">' + compute("TotalOrderMoney") + '</span>',
TotalOrderScore: '<span class="subtotal">' + compute("TotalOrderScore") + '</span>',
TotalTrailCount: '<span class="subtotal">' + compute("TotalTrailCount") + '</span>',
Rate: '<span class="subtotal">' + ((compute("TotalOrderScore") / compute("TotalTrailCount")) * 100).toFixed(2) + '</span>'
});
}
//指定列求和
function compute(colName) {
var rows = $('#table').datagrid('getRows');
var total = 0;
for (var i = 0; i < rows.length; i++) {
total += parseFloat(rows[i][colName]);
}
return total;
}
</script>
