我有一个ASP .NET webforms应用程序,员工正在填写时间表。我有一个包含ASP的表格:TextBox用于用户输入,我想要做的是计算当前行和当前列中小时的总和。
我已经看过前面这个例子了:SUM Total for Column它让我非常接近。我在任何文本框的每个keyup上运行以下javascript:
var totalsByRow = [0, 0, 0, 0, 0];
var totalsByCol = [0, 0, 0, 0, 0];
$(document).ready(function () {
$('.sum').keyup(function (e) {
var $dataRows = $("#sum_table tr:not('.totalColumn, .titlerow')");
$dataRows.each(function (i) {
$(this).find('td:not(.totalRow)').each(function (j) {
totalsByCol[j] += parseFloat($(this).val());
totalsByRow[i] += parseFloat($(this).val());
});
});
for (var i = 0; i < totalsByCol.length - 1; i++) {
totalsByCol[totalsByCol.length - 1] += totalsByCol[i];
}
$("#sum_table td.totalCol").each(function (i) {
$(this).html("total:" + totalsByCol[i]);
});
$("#sum_table td.totalRow").each(function (i) {
$(this).html("total:" + totalsByRow[i]);
});
});
});
&#13;
问题很简单:$(this).html()没有得到文本框的值。我还尝试了基于其他帖子的$(this).val()和$(this).value但没有成功。那么如何获取调用此keyup函数的文本框的值?
编辑:
我使用的HTMl代码只是一个简单的测试表,我已经设置好了。这是为了进一步澄清:
<script src="TotalForm.js"></script>
<table id="sum_table" border="1">
<tr class="titlerow">
<td>Apple</td>
<td>Orange</td>
<td>Watermelon</td>
<td>Strawberry</td>
<td>Total By Row</td>
</tr>
<tr>
<td class="rowAA">
<asp:TextBox runat="server" ID="TextBox1" CssClass="sum"></asp:TextBox>
</td>
<td class="rowAA">
<asp:TextBox runat="server" ID="TextBox2" CssClass="sum"></asp:TextBox>
</td>
<td class="rowBB">
<asp:TextBox runat="server" ID="TextBox3" CssClass="sum"></asp:TextBox>
</td>
<td class="rowBB">
<asp:TextBox runat="server" ID="TextBox4" CssClass="sum"></asp:TextBox>
</td>
<td class="totalRow"></td>
</tr>
<tr>
<td class="rowAA">
<asp:TextBox runat="server" ID="TextBox5" CssClass="sum"></asp:TextBox>
</td>
<td class="rowAA">
<asp:TextBox runat="server" ID="TextBox6" CssClass="sum"></asp:TextBox>
</td>
<td class="rowBB">
<asp:TextBox runat="server" ID="TextBox7" CssClass="sum"></asp:TextBox>

<td class="rowBB">

<td class="totalRow"></td>
</tr>
<tr>
<td class="rowAA">
<asp:TextBox runat="server" ID="TextBox9" CssClass="sum"></asp:TextBox>
</td>
<td class="rowAA">
<asp:TextBox runat="server" ID="TextBox10" CssClass="sum"></asp:TextBox>
</td>
<td class="rowBB">
<asp:TextBox runat="server" ID="TextBox11" CssClass="sum"></asp:TextBox>
</td>
<td class="rowBB">
<asp:TextBox runat="server" ID="TextBox12" CssClass="sum"></asp:TextBox>
</td>
<td class="totalRow"></td>
</tr>
<tr class="totalColumn">
<td class="totalCol">Total:</td>
<td class="totalCol">Total:</td>
<td class="totalCol">Total:</td>
<td class="totalCol">Total:</td>
<td class="totalCol">Total:</td>

编辑此部分代码
$dataRows.each(function (i) {
$(this).find('td:not(.totalRow)').each(function (j) {
totalsByCol[j] += parseFloat($(this).val());
totalsByRow[i] += parseFloat($(this).val());
});
});
通过
$dataRows.each(function (i) {
$(this).find('td:not(.totalRow)').each(function (j) {
totalsByCol[j] += parseFloat($(this).find(".sum").val());
totalsByRow[i] += parseFloat($(this).find(".sum").val());
});
});
.fin(&#34; sum&#34;)找到输入文本控件。
