Say you have two buttons like this 假设您有两个这样的按钮
<input type="button" name="confirm" id="confirm" value="confirm">
<input type="button" name="discard" id="discard" value="discard">
You can use jquery event handlers for getting which button is clicked like this 您可以使用jquery事件处理程序来获取像这样单击的按钮
$(document).ready(function() {
$("#confirm").on('click',function(){
alert('Confirm clicked');
//If you need to communicate with the server the do an ajax call here
});
$("#discard").on('click',function(){
alert('Discard clicked');
//If you need to communicate with the server the do an ajax call here
});
});
You can check for the click event reference from HERE 您可以从HERE检查点击事件参考

You can do with php, extract state of fields with environment php variables, you just make an formular and send some data to your webserver script-file. 您可以使用php，使用环境php变量提取字段状态，您只需制作一个公式并将一些数据发送到您的webserver脚本文件。
<?php
$confirm = $_POST["name_of_the_button"]
if(isset($confirm))
{
some script
}
else
{
other script
}
-----EDIT-----: - - -编辑 - - -：
I made it with two files: 我用两个文件制作了它：
File: form.php 文件：form.php
<html>
<head>
<title>Button test</title>
<script type="application/javascript">
function ajaxObj()
{
var xmlHttp=null;
try
{
// Browsers Firefox, Opera 8.0+, Safari;
xmlHttp=new XMLHttpRequest();
}
catch(e)
{
try
{
// Browser Internet Explorer;
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e)
{
try
{
// Other browsers
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e)
{
// Your browser does not suport XMLhttp object
alert('Your browser does not suport XMLhttp object');
return false;
}
}
}
return xmlHttp;
}
function doQuery(id)
{
xmlHttp=ajaxObj();
if(xmlHttp==null)
{
alert('Your browser does not suport XMLhttp object');
return;
}
xmlHttp.open("POST","check.php",true);
var send = 'id='+id;
xmlHttp.onreadystatechange=function()
{
if (xmlHttp.readyState==4 && xmlHttp.status==200)
{
document.getElementById("output").innerHTML=xmlHttp.responseText;
}
}
xmlHttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlHttp.send(send);
}
</script>
</head>
<body>
<button id="confirmed" name="button" onclick="doQuery(this.id)">Confirm</button>
<button id="declined" name="button" onclick="doQuery(this.id)">Decline</button>
<div id="output"></div>
</body>
</html>
File check.php: 文件check.php：
<?php
$action = $_POST["id"];
$confirm = false;
if($action=="confirmed")
$confirm = true;
else if($action=="declined")
$confirm = false;
else {}
?>

if You use javascript then use belo:- 如果您使用javascript然后使用belo： -
if(window.confirm("please confirm"))
{
return true;
// or do Your operation.
}
else{
return false;
// or do Your operation.
}
otherwise You can use jquery. 否则你可以使用jquery。

<input type="button" name="confirm" id="confirm" value="confirm">
<input type="button" name="discard" id="discard" value="discard">
$(document).ready(function() {
$("input:button").on('click',function(){
if($(this).id == 'confirm'){
// put your script here
}else{
// put your script here }
});
});
