我在网站视图中有一个包含3列和4行的表格。我需要添加列值并在表格底部显示为总计。我使用的是spring mvc3。如何计算JSP中的总和？
但这个代码我上网了。它的输入类型是＆＃34; text＆＃34;。我的要求是将从db检索到的列的值添加到表
表格似乎
<script>
function calculateSum() {
var sum = 0;
//iterate through each textboxes and add the values
$(".txt").each(function() {
//add only if the value is number
if(!isNaN(this.value) && this.value.length!=0) {
sum += parseFloat(this.value);
}
});
//.toFixed() method will roundoff the final sum to 2 decimal places
$("#sum").html(sum.toFixed(2));
}
