If you want to style your alert, check this plugin: jquery-alert-dialogs. It's very easy to use.
如果要设置警报样式，请查看此插件：jquery-alert-dialogs。它非常容易使用。
jAlert('This is a custom alert box', 'Alert Dialog');
jConfirm('Can you confirm this?', 'Confirmation Dialog', function(r) {
jAlert('Confirmed: ' + r, 'Confirmation Results');
});
jPrompt('Type something:', 'Prefilled value', 'Prompt Dialog', function(r) {
if( r ) alert('You entered ' + r);
});

In JavaScript, that type of box is confirm, not alert. confirmreturns a boolean, representing whether the user responded positively or negatively to the prompt (i.e. clicking OKresults in truebeing returned, whereas clicking cancelresults in falsebeing returned). This is applicable to jQuery, but also in JavaScript more broadly. You can say something like:
在 JavaScript 中，这种类型的框是confirm，而不是alert。 confirm返回一个布尔值，表示用户对提示的响应是肯定的还是否定的（即单击OK导致true返回，而单击cancel导致false返回）。这适用于 jQuery，但也适用于更广泛的 JavaScript。你可以这样说：
var shouldDelete = confirm("Do you want to delete?");
if (shouldDelete) {
// the user wants to delete
} else {
// the user does not want to delete
}

Might not be jquery but is the simple principle that you could use
可能不是 jquery，而是您可以使用的简单原则
<html>
<head>
<script type="text/javascript">
function show_confirm()
{
var r=confirm("vote ");
if (r==true)
{
alert("ok delete"); //you can add your jquery here
}
else
{
alert(" Cancel! dont delete"); //you can add your jquery here
}
}
</script>
</head>
<body>
<input type="button" onclick="show_confirm()" value="Vote to delete?" /> <!-- can be changed to object binding with jquery-->
</body>
</html>Vot
