<table style="width: 100%; height: 100%" border="1">

<tbody><tr> 
<td>

</td> 
<td> 
<input type="hidden" name="hidProjectInnerID" id="hidProjectInnerID"> 
<input name="txtProjectNo" type="text" id="txtProjectNo" class="Error"><a href="javascript:void(0)" onclick="SelectProject();">選擇</a>

</table> 

復(fù)制代碼代碼如下:

 
function SaveItem(index) { 
var tr = $("tr[id=" + index + "]"); 
var innerid = tr.find('input[ID$=txtInnerID]').val(); 
var item = tr.find("select[id*=selItem]").val(); 
var des = tr.find('input[ID$=txtDescription]').val(); 
var qty = tr.find('input[ID$=txtQTY]').val(); 
var unit = tr.find('input[ID$=txtUnit]').val(); 
var total = tr.find('input[ID$=txtTotal]').val(); 
var remark = tr.find('input[ID$=txtRemark]').val(); 
//alert(innerid + "/" + item + des + qty + unit + total + remark); 
//驗證項目編號 
var proinnerid = $("#hidProjectInnerID").val(); 
if (proinnerid == "") { 
$("#txtProjectNo").removeClass("Field"); 
$("#txtProjectNo").addClass("Error"); 
return false; 
} 
/* 
jQuery.ajax({ 
type: 'get', 
url: '../Handler/ProjectReport.ashx', 
data: { "key": "save", "proinnerid": $("#hidProjectInnerID").val(), "innerid": innerid, "type": type, "content": content, "startdate": startdate, "enddate": enddate, "remark": remark }, 
cache: false, 
success: function (result) { 
var jsonobj = eval(result); 
if (jsonobj[0].result == "true") 
alert("Sueecss"); 
else 
alert("Error"); 
} 
}); 
*/ 
} 
function DelItem(index) { 
var tr = $("tr[id=" + index + "]"); 
//var innerid = tr.find('input[ID$=txtInnerID]').val(); 
$("tr[id=" + index + "]").remove(); 
}
