Question

我想使用 javascript prompt() 方法实现 3 次尝试登录表单。它显示您已经尝试了 2 次，并且 ddnt 检查下一次尝试。如何解决这个问题？这是我的脚本

<script type="text/javascript">
    var attempt = 3;
    var userName=prompt("Username","");
    var passWord=prompt("Password","");
    if (userName+passWord=="john2541798432" || userName+passWord=="tim3591798752") 
    {
    alert('success');
}       
else
{
attempt --;// Decrementing by one.
alert("You have left "+attempt+" attempt;");
if( attempt == 0)
{
    alert('you are blocked');
}
}
</script>
