ASP Web窗體後面的條件

Question

事件防火規範我的ASP.NET Web窗體應用程序

<asp:Button ID="DeleteDealsButton" runat="server" Text="Delete" /> 

function btnDeleteClick() { 
    var result = confirm("Want to delete all Deals?"); 
    if (result) { 
     return true; 
    } else { 
     return false; 
    } 
} 

$("#MainContent_DeleteDealsButton").on("click", function() { 
     if (btnDeleteClick()) {}) 

這個按鈕我有樣品的JavaScript警告問OK或Cancel.I希望如果選擇OK來觸發CODE BEHIND方法調用DeleteDealsButton_Click，如果取消則不做任何事情。

Answer 1

剛更改按鈕定義爲，

<asp:Button ID="DeleteDealsButton" runat="server" Text="Delete" OnClientClick="return confirm('Want to delete all Deals?')" /> 

不需要任何javascript函數。

Answer 2

嘗試這樣的：

function btnDeleteClick() { 
var confirm_value = document.createElement("INPUT"); 
confirm_value.type = "hidden"; 
confirm_value.name = "confirm_value"; 
confirm_value.value = "No"; 
var result = confirm("Want to delete all Deals?"); 
if (result) { 
    confirm_value.value = "Yes"; 
    __doPostBack('DeleteDealsButton', '') 
    return true; 
} else { 
    confirm_value.value = "No"; 
    return false; 
} 
} 

在.aspx文件更改按鈕的代碼是這樣的：

<asp:Button ID="DeleteDealsButton" OnClientClick=" return btnDeleteClick()" runat="server" Text="Delete" OnClick="DeleteDealsButton_Click" /> 

在你.Aspx.cs文件

protected void DeleteDealsButton_Click(object sender, EventArgs e) 
    { 
    string confirmValue = Request.Form["confirm_value"]; 
    if (!String.IsNullOrWhiteSpace(confirmValue) && confirmValue.Equals("Yes")) 
    { 
    } 
}
