Javascript 如何使用asp.net从文本框调用函数？
我一直在尝试调用函数Javascript 如何使用asp.net从文本框调用函数？,javascript,asp.net,Javascript,Asp.net,我一直在尝试调用函数formattate（）。我试着把它放在text=”“/value=”“中，但它没有正确返回 我怎样才能解决这个问题 <asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1 Runat="Server"> <script type="text/javascript"> function formatDate(date) {
formattate（）text=”“value=”“<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1 Runat="Server">
<script type="text/javascript">
function formatDate(date) {
var d = new Date(date),
month = '' + (d.getMonth() + 1),
day = '' + d.getDate(),
year = d.getFullYear();
year = year.toString().substr(2, 2);
dateRecord = [year, month].join('/');
return dateRecord
}
</script>
<h2><asp:Label ID="lblPageName" Text="Project Seq Code" runat="server" /></h2>
<table width="625" cellpadding="0" cellspacing="1" style="margin-left:180px;">
<tr>
<td> Report </td>
<td><asp:Textbox id="txtReport" text="return formateDate(date)" Runat="Server" Width="250px" />
</td>

这可能是您问题的解决方案。我还没有测试过，但我正在用同样的东西工作。我只是以另一种方式来做，使用带有jQuery和ASP服务器端代码的HTML输入来访问这些控件
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1 Runat="Server">
<script type="text/javascript">
function formatDate(date) {
var d = new Date(date),
month = '' + (d.getMonth() + 1),
day = '' + d.getDate(),
year = d.getFullYear();
year = year.toString().substr(2, 2);
dateRecord = [year, month].join('/');
$("#txtReport").val(dateRecord);
}
</script>
<h2><asp:Label ID="lblPageName" Text="Project Seq Code" runat="server" /></h2>
<table width="625" cellpadding="0" cellspacing="1" style="margin-left:180px;">
<tr>
<td> Report </td>
<td><asp:Textbox id="txtReport" ClientIDMode="Static" Runat="Server" Width="250px" />
</td>
</tr>
</table>
</asp:Content>
jQuery？很有趣..让我试试。jQuery让它变得容易多了。如果你愿意的话，可以用纯JS来完成吗？我刚刚添加了另一段代码，只是为了说明它可以用纯JS的jQuery来完成。最好的情况是，我添加了另一个文本框用于这两种方法。我希望我能帮你解决你的问题；）
<asp:Textbox id="txtReport" ClientIDMode="Static" Runat="Server" Width="250px"></asp:Textbox>

//Placing your date with jQuery
$(document).ready(function () {
$("#txtReport").val(dateRecord + " - this was done with jQuery");
