就是如果 在合并行里已经默认有值的话，我在文本框中输入的时候如何相加。现在的效果是，在合并行中默认为0 的时候相加是正常的。
<html>
<head>

<script>
function countme(obj,div_id,pre_id){
if(obj.value!=''){
//前一个值
var preval = document.getElementById(pre_id).value;
//当前div值
var t = document.getElementById(div_id+'_value').value;
//显示
document.getElementById(div_id).innerHTML = parseInt(t) + parseInt(obj.value) - parseInt(preval);
//赋前一个值
document.getElementById(pre_id).value = obj.value;
//赋当前div值
document.getElementById(div_id+'_value').value = parseInt(t) + parseInt(obj.value) - parseInt(preval);
}
}
