Question

如何获取所选确认框的值：

我有这段代码：

string scriptString = "<script language='JavaScript'> ";
scriptString += "confirm ('Are you sure you want to Close this period.')";
scriptString += "</script>";
Response.Write(scriptString);

有没有办法确定你选择是或否？

Answer 1

var x = confirm('...')
alert(x)

或

string scriptString = "<script language='JavaScript'> ";
scriptString += "var x = confirm ('Are you sure you want to Close this period.')";
scriptString += "alert(x)";            
scriptString += "</script>";
Response.Write(scriptString);

Answer 2

确认返回一个布尔值，表示确定或取消（true表示确定，false表示取消）。

你可以像这样使用它：

if(confirm ('Are you sure you want to Close this period.')) {
  //they clicked ok
}
else {
  //they clicked cancel
}

Answer 3

您应该将确认结果存储在隐藏字段值中，如下所示：

if (confirm("Are you sure you want to proceed?")==true){
    hiddenField.value = 'true';
    return true;
} else {
    hiddenField.value = 'false';
    return false;
}

然后从C＃

中获取隐藏字段的值

从确认框中获取价值
