ascx控件不触发JavaScript的

Question

我的.ascx低于件

function confirmationDelete() 
    {  
     var r = confirm("Are you sure you want to delete this target"); 
     if (r == true) { 
      return true; 
     } else { 
      return false; 
     } 
    } 


<asp:Button ID="btnDeleteTarget" runat="server" Text="Delete Target" CssClass="btnDeleteTargetClass" ValidationGroup="validateformgroup" CausesValidation="true" OnClick="btnDeleteTarget_Click" Visible="False" /> 

ascx.cs低于线

btnDeleteTarget.OnClientClick = "return confirmationDelete()"; 

我仍然没有得到确认提示。页面只是刷新。我究竟做错了什么？

尝试在开发人员工具栏中放置断点，但它不调用我的JS函数。

Answer 1

试试这个代码

在你*的.ascx：

<asp:Button ID="btnDeleteTarget" runat="server" Text="Delete Target" CssClass="btnDeleteTargetClass" ValidationGroup="validateformgroup" CausesValidation="true" OnClick="btnDeleteTarget_Click" Visible="False" /> 

在的.cs C＃：

protected void Page_Load(object sender, System.EventArgs e) 
{ 
    if (!IsPostBack) 
    { 
     btnDeleteTarget.Attributes["Onclick"] = "return confirm('Do you want Delete ?')";   
    } 
} 

protected void btnDeleteTarget_Click(object sender, EventArgs e) 
{ 
    Page.Validate(); 
    if (Page.IsValid) 
    { 
     //Delete all 
    } 
} 

Answer 2

使用此您的按钮中的OnClientClick属性：

OnClientClick="return confirm('Are you sure you want to delete?');" 

这将是你的代码：

<asp:Button ID="btnDeleteTarget" runat="server" Text="Delete Target" CssClass="btnDeleteTargetClass" ValidationGroup="validateformgroup" CausesValidation="true" OnClientClick="return confirm('Are you sure you want to delete?');" Visible="False" />
