ASP Web 窗体根据条件触发事件背后的代码

Question

我有 ASP.NET 个 WEB FORMS 应用程序

<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()) {})

在这个按钮上，我有示例 javascript 警报询问确定或 Cancel.I 如果选择确定，则希望触发 CODE BEHIND 方法调用 DeleteDealsButton_Click，如果选择取消，则不执行任何操作。

Answer 1

这样试试：

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;
}
}

在您的 .Aspx 文件中将您的按钮代码更改为如下所示：

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

在您的 .Aspx.cs 文件中

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

Answer 2

只需将按钮定义更改为，

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

不需要任何 javascript 功能。
