我有一个问题，我有一个按钮，如下图所示：

I have a question, I have a button like below:

<asp:Button ID="savebtn" runat="server" OnClick="savebtn_Click" Visible="false" />

我再有像像下面的HTML按钮：

I then have HTML button like like below:

<button id="btnsave" onclick="fncsave">Save</button>

我有以下的javascript：

I have the javascript below:

<script type="text/javascript">
     function fncsave()
     {
        document.getElementById('<%= savebtn.OnClick %>').click()
     }
</script>

我现在的问题是，我怎么能调用ASP：按钮的OnClick从HTML按钮？我已阅读，你可以从JavaScript凭身份证要求这样做，但不工作。

My question now is, how can I call the asp:Button OnClick from the HTML button? I have read you can do this by calling from JavaScript by Id but is not working.

任何帮助将是非常美联社preciate吧。

Any help will be really appreciate it.

感谢您

推荐答案

设置样式=显示：无。通过设置可见=假，也不会呈现在浏览器这样的客户端脚本不会执行按钮。

Set style = display:none. By setting visible = false, it will not render button in the browser thus client side script wont execute.

<asp:Button ID="savebtn" runat="server" OnClick="savebtn_Click" style="display:none" />

HTML标记应该是

html markup should be

<button id="btnsave" onclick="fncsave()">Save</button>

更改JavaScript，以

Change javascript to

<script type="text/javascript">
     function fncsave()
     {
        document.getElementById('<%= savebtn.ClientID %>').click();
     }
</script>
