我正在使用jquery循環錶行並保存數據。如果表格有200行,表現緩慢。當我調用此方法時,我正在IE中獲取JavaScript消息「停止運行此腳本」。以下是我用來循環表格行的代碼。你能否讓我知道是否有更好的方法來做到這一點。性能問題循環通過錶行
function SaveData() {
var $table = $('#' + gridid);
var rows = $table.find('tbody > tr').get();
var transactions = [];
var $row, empno, newTransaction, $rowChildren;
$.each(rows, function(index, row) {
$row = $(row);
$rowChildren = $row.children("td");
if ($rowChildren.find("input[id*=hRV]").val() === '1') {
empno = $rowChildren.find("input[id*=tEmpno]").val();
newTransaction = new Array();
newTransaction[0] = company;
newTransaction[1] = $rowChildren.find("input[id*=tEmpno]").val();
newTransaction[2] = $rowChildren.find("input[id*=tPC]").val();
newTransaction[3] = $rowChildren.find("input[id*=hQty]").val();
newTransaction[4] = $rowChildren.find("input[id*=hPR]").val();
newTransaction[5] = $rowChildren.find("input[id*=tJC]").val();
newTransaction[6] = $rowChildren.find("input[id*=tL1]").val();
newTransaction[7] = $rowChildren.find("input[id*=tL2]").val();
newTransaction[8] = $rowChildren.find("input[id*=tL3]").val();
newTransaction[9] = $rowChildren.find("input[id*=tL4]").val();
newTransaction[10] = $rowChildren.find("input[id*=tL5]").val();
newTransaction[11] = $rowChildren.find("input[id*=tL6]").val();
newTransaction[12] = $rowChildren.find("input[id*=tL7]").val();
newTransaction[13] = $rowChildren.find("input[id*=tL8]").val();
newTransaction[14] = $rowChildren.find("input[id*=tL9]").val();
newTransaction[15] = $rowChildren.find("input[id*=tL10]").val();
newTransaction[16] = $rowChildren.find("input[id*=tSF]").val();
newTransaction[17] = $rowChildren.find("input[id*=tCG]").val();
newTransaction[18] = $rowChildren.find("input[id*=tTF]").val();
newTransaction[19] = $rowChildren.find("input[id*=tWK]").val();
newTransaction[20] = $rowChildren.find("input[id*=tAI]").val();
newTransaction[21] = $rowChildren.find("input[id*=tWC]").val();
newTransaction[22] = $rowChildren.find("input[id*=tPI]").val();
newTransaction[23] = "E";
var record = newTransaction.join(';');
transactions.push(record);
}
});
if (transactions.length > 0) {
var strTransactions = transactions.join('|');
//send data to server
//here ajax function is called to save data.
}
}
HTML結構的錶行是這樣的

你可以發佈一些示例html標記?如果這些輸入符合一致的html結構,可能會使這一過程更簡單。 – 2010-04-04 04:33:18

我在原貼中發佈了html標記。 – Sridhar 2010-04-04 15:36:15
