//function:代码演示了如何透过javascript手工添加数据行，并通过dom为数据行动态添加ID，以方便输入料号名称后通过ajax技术自动带出料号的描述，并告知如何针对返回数据为空时如何处理( part_desc以及vendor_desc中所示)
1、po_add.php

sum=5;

var temp;
if (num == '')
num = 1;
for (i=0;i<num;i++){
sum=sum+1;
if (sum % 2 == 0){
var newRow=tbDetailHide1.rows[0].cloneNode(true);
}else if (sum % 2 != 0){
var newRow=tbDetailHide2.rows[0].cloneNode(true);
}
temp=sum*1;
newRow.all.a.value=temp;
tbDetailUsed.insertBefore(newRow);
var partid = 'part_id' + (sum);
tbDetailUsed.rows[sum].firstChild.nextSibling.firstChild.setAttribute('id',partid);
}
}
function auto_upper_str(strObj) {
strObj.value = strObj.value.toUpperCase();
}
function autoInput(){
var e;
with(document.myform){
var tmp1 = document.myform.po_req_date.value;
for (var i=0;i<elements.length;i++){
e = elements[i];
if (e.tagName == "INPUT" && e.type.toLowerCase() == "text" && e.name.substr(0,12) == "pod_req_date"){
e.value = tmp1;
}
}
}
