推荐答案

您好，

因此，请提供您的隐藏字段和ID，如下所示:

Hi there,

So give your hidden field and ID like so:

<input type="hidden" value="SomeValue" id="MyHiddenInputID" />

或在C#中执行:

or in C# do:

MyHiddenInput.ID = "MyHiddenInputID";

然后在javascriot中使用document对象访问其值:

Then in javascriot use the document object to access it''s value:

document.getElementById("MyHiddenInputID").value

您的完整按钮C#行将如下所示:

Your full button C# line would then look like:

btn.Attributes.Add("onclick", "javascript: xyz('" + this.ClientID + "', document.getElementById(\"MyHiddenInputID\").value);");

请记住，使用HtmlButton(来自HTML控件)而不是按钮(来自WebControls)-后者不会为您提供html input [type = button]但会给您html input [type = submit]-这不是您想要的.

希望这会有所帮助，

Remember to use HtmlButton (from HTML Controls) not a Button (from WebControls) - the latter will not give you an html input[type=button] but and html input[type=submit] - which isn''t what you want.

Hope this helps,

btn.Attributes.Add("onclick", "javascript: xyz('" + this.ClientID + "',document.getElementById('"+this.ClientID+"_HdnText').value);")
