在asp.net中发出警报并确认 [英] Alert and Confirm in asp.net

问题描述

我在按钮单击事件上编写了功能，但没有触发警报.
btnSubmit.Attributes.Add("onclick"，"return check();");-背后的代码
function check()-cleint端的Java脚本
{
alert("KRA不能为空");
}
并在第二次单击确认火灾.

btnSubmit.Attributes ["onClick"] ="javascript:return check();";-背后的代码
function check()-cleint端的Java脚本
{
var answer = confirm(您确定要保存吗?")
如果(回答)
{
返回true;
}
其他
返回false;
}
请提出建议.

I write function on button click event but alert didn''t fire.
btnSubmit.Attributes.Add("onclick", "return check();");--code Behind
function check() --Java Script on cleint side
{
alert("The KRA can''t empty");
}
And Confirm fires on 2nd click.

btnSubmit.Attributes["onClick"] = "javascript:return check();";--code Behind
function check() --Java Script on cleint side
{
var answer = confirm("Are you sure to save ?")
if (answer)
{
return true;
}
else
return false;
}
Kindly suggest,please.

推荐答案

尝试一下，

Try this,

btnSubmit.Attributes.Add("onclick", "javascript:return check()")

按照Toni的说法尝试.还要根据您的要求从函数check 返回true or false.

Try as Toni says. Also return true or false from function check based on your requirement.

在页面加载中添加以下代码.

Add the below code in page load.

protected void Page_Load(object sender, EventArgs e)
{
    btnSubmit.Attributes.Add("onclick","javascript:return check()");
}
