c# - 从 CodeBehind 调用 Javascript 函数并返回值

Question

我有一些看起来像这样的代码，都在代码隐藏中......

var script = "confirm('Would you like to close this order?')";
ClientScript.RegisterStartupScript(typeof(Page), "CloseOrder", script, true);

如何获取用户是否在下一行单击是或否的值？是否有可能当此脚本触发时，它会返回该值并在代码隐藏的下一行继续？

Answer 1

var script = function(){
    var choice = confirm('Would you like to close this order?');
    if(choice){
        //If the user clicks yes
    }else{
        //If the user clicks no
    }
}
ClientScript.RegisterStartupScript(typeof(Page), "CloseOrder", script, true);

Answer 2

这里的简单示例：http: //jsfiddle.net/ChaseWest/W569P/

改变：var script = "confirm('Would you like to close this order?')";

至：var script = confirm('Would you like to close this order?');

这将根据确认弹出框的是或否将真或假保存到脚本中。
