javascript - 无法从 JavaScript 启用按钮

Question

这个问题已经有答案了:

Can't Enable button in JavaScript (1 个回答)

已关闭 4 年前。

<script type="text/javascript"> 
 function Enable_Butt() {               
     document.getElementById("<%=RadButton1.ClientID%>").disabled = false; // Doesn't Work                                                      
 }
</script>

我也尝试过这个，但仍然不起作用:

$find("<%=RadButton1.ClientID %>").set_enabled(true);

我的代码:

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
  <ContentTemplate>
   <telerik:RadButton ID="RadButton1" runat="server"  SingleClick="true" SingleClickText="Processing..." AutoPostBack="true" OnClick="Create_Order_Click" Text="Create Order" Font-Bold="true" Font-Size="12" BackColor="#333333" ForeColor="White" Skin="Bootstrap" CssClass="auto-style5"  >
   </telerik:RadButton>
   <asp:Timer ID="Timer1" runat="server" OnTick="Timer1_Tick" Interval="5000" ></asp:Timer>
  </ContentTemplate>
  <Triggers>
   <asp:AsyncPostBackTrigger ControlID="RadButton8" EventName="Click" />
   <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
  </Triggers>
</asp:UpdatePanel>


protected void Timer1_Tick(object sender, EventArgs e){
 ScriptManager.RegisterStartupScript(Page, Page.GetType(), " ", "Enable_Butt()", true);
}

只需完全删除该属性即可。

document.getElementById("<%=RadButton1.ClientID%>").removeAttribute("disabled");
