jquery获取tr中控件值并操作tr实现思路

代码如下:

<table style="width: 100%; height: 100%" border="1">
<caption>
material/special tool rental/tool cantainer/transportation/mobile</caption>
<tbody><tr>
<td>
project no
</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();">选择</a>
</td>
<td>
final custome:
</td>
<td>
<span id="labfinalcustome">label</span>
</td>
<td>
order no.
</td>
<td>
<span id="laborderno">label</span>
</td>
<td>
project leaing time:
</td>
<td>
<span id="labprojectleaingtime">label</span>
</td>
</tr>
<tr>
<td colspan="8">
exchange rate:8.3000
</td>
</tr>
<tr align="center">
<td>
item
</td>
<td colspan="2">
description
</td>
<td>
qty
</td>
<td>
unit
</td>
<td>
total
</td>
<td>
remark
</td>
<td>
<a id="newitem" href="javascript：void(0)">newitem</a>
</td>
</tr>
</tbody><tbody id="tbitem">
<tr align="center">
<td>
</td>
<td colspan="2">
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>

</td>
</tr>
<tr id="tbitem1" align="center"><td><select id="selitem" name="item"><option value="material">material</option><option value="mobile">mobile</option><option value="others">others</option><option value="specialtoolrental">special tool rental</option><option value="toolcontainer">tool container</option><option value="transportation">transportation</option><option value="workinghours">workinghours</option></select></td><td colspan="2"><input id="txtdescription" style="width:90%" type="text" name="item"></td><td><input id="txtqty" type="text" name="item"></td><td><input id="txtunit" type="text" name="item"></td><td><input id="txttotal" type="text" name="item"></td><td><input id="txtremark" type="text" name="item"></td><td><a href="javascript：;saveitem('tbitem1')">保存</a> | <a href="javascript：;delitem('tbitem1')">删除</a> <input id="txtinnerid" type="hidden" name="item"></td></tr></tbody>
</table>

. 代码如下:

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);
//验证项目编号
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();
}
