推荐答案

向按钮添加AutoPostBack =false。您还可以添加OnClick =javascript：return void（0）;。



如果这样可以解决您的问题，请花点时间接受解决方案，以便其他人可以找到它。

谢谢。

Add AutoPostBack="false" to the button. You might also add OnClick="javascript: return void(0);".

If this solves your problem please take the time to accept the solution so others can find it.
Thank you.

如果你从你的javascript函数返回false ，它会阻止回发。



如果你将你的功能修改为：

Hi,

if you return false from your javascript function, it will prevent the postback.

If you modify your function to:

function myfunction()
     {
        document.getElementById("demo").innerHTML="Welcome TO JAVA SCRIPT";
        return false;
     }

并将您的按钮修改为：

and modify your button to:

<asp:Button ID="Button1" runat="server" Text="Try IT" OnClientClick="return myfunction();" />

希望它有所帮助。

Hope it helps.
