当我们在gridview显示统计信息时，都会想在gridview最后一行显示【小计】结果，但gridview的话好像比较难搞(至少我也不会呀 囧~)，那么我就结合jquery写了一个解决方案，下面举个例子。

为了能够在gridview的最后一行显示统计信息，于是加入如下的javascript
$(function () {
var sumHours = 0, sumCounts = 0, sumNums = 0;
var trObj = "";
var begLen = 8; //開始統計第一個<td>的索引值
var sunLen = 21; //連續的需要統計的td總數
var arys = new Array(sunLen);
for (var a = 0; a < sunLen; a++) {
arys[a] = 0;
}
//開始匯總計算并將結果存入數組當中
$(".tbinfo tr").each(function (i) {
if (i > 0) {
for (var j = 0; j < sunLen; j++) {
if ($(this).find("td:eq(" + j + begLen + ")").html() != NaN) {
//arys[j] += parseFloat($(this).find("td:eq(" + j + begLen + ")").html());
arys[j] += parseFloat($(this).find("td").eq(j + begLen).html());
}
}
sumCounts++;
}
});
//拼裝<tr>字符串
trObj = "<tr style='font-size:12px;font-weight:bold;border-bottom:1px solid #a5ceef;color:#003399; '><td style='background-color:#97CBFF;' align='center'>上班天數:</th><td style='background-color:#97CBFF;' align='left' colspan='3'>" + sumCounts + "天</td>";
trObj += "<td style='background-color:#97CBFF;' colspan='3'> </td><td style='background-color:#97CBFF;' align='right'>總計:</td>";
for (var k = 0; k < sunLen; k++) {
trObj += "<td style='background-color:#97CBFF;' align='right'>" + Math.round(arys[k] * 10) / 10 + "</td>";
}
trObj += "<td style='background-color:#97CBFF;'> </td></tr>";
//在最后一行的<tr>后面插入
$(".tbinfo tr").eq(-1).after(trObj);
//最后一步，格式化所有值為0的項
var tbl = $(".tbinfo").html();
tbl = tbl.replaceAll(">0.0<", "> <");
tbl = tbl.replaceAll(">0<", "> <");
$(".tbinfo").html(tbl);
});
function showPrint() {
$("body").html($("#divPrint").html());
window.print();
}
//為系統追加replaceAll方法
String.prototype.replaceAll = function (oldStr, newStr) {
return this.replace(new RegExp(oldStr, "gm"), newStr);
}最后的效果如下图所示：
