在文本框中输入按键 [英] enter key press in textbox

问题描述

我写了输入密钥的代码：

I write the code for enter key:

 <script type="text/javascript">
        function fncsave() {
            var k = (event.keyCode ? event.keyCode : event.which);
            //var k = event.keyCode;
            //alert(k);
            if (parseInt(k) == '13') {
 alert(k);
                document.getElementById('<%= imgbtnReply.ClientID %>').click();
            }

     }
</script>

，按钮点击事件为：

and the button click event is:

<asp:ImageButton ID="imgbtnReply" runat="server" ImageUrl="/tmpfimages/member/tmpf00151.png" CssClass="rply_adjst" OnClick="imgbtnReply_Click"  />
       <div class="areaspace"> </div>
       <asp:TextBox ID="txtReply"   CssClass="adtxtbx"  runat="server"  OnKeyPress="fncsave()"></asp:TextBox>

这里按钮点击事件没有通过javascript激活。请更好地帮助我。

here the button click event didn't fire through javascript.Please assist me better.

推荐答案

当你使用一个imagebutton asp.net也会在页面上添加一个img标签作为特殊的javascript，它侦听点击事件并在检测到它时运行代码。在图像上调用任何本机点击事件不会触发由处理回发的.net放置在页面上的代码，您需要自己触发该代码。

When you use an imagebutton asp.net puts an img tag on the page as well as special javascript that listens for click events and runs its on code when it detects them. Calling any native click event on an image isn't going to trigger the code placed on the page by .net that handles the postback, you'll need to trigger that code yourself.
