用于检查用户名可用性的Javascript帖子无效

Im trying to check if the register username's available but everytime the clientside returns that the username its available.

我试图检查注册用户名是否可用,但每次客户端返回该用户名可用时。

This is my clientside code:

这是我的客户代码:

$(document).ready(function()
{
    $("#register_username").blur(function(){
    var user = $("#register_username").val();
    $.post("register",
    {
        username: user
    },
    function(data, status){
        if(data == '1')
        {
            alert('Good, username its available!');
        }
        else
        {
            alert('Snap!You cant use this username :(!');
        }
        });
    });
});

And this is the serverside code:

这是服务器端代码:

if(strlen($_POST['username']) > 0)
{
    $usr = $_POST['username'];
    if($usr == 'test')
        echo '1';
    else
        echo '2';
}

first of all, i guess if the input field has value "test" it would say "you cannot use this username"?

首先,我猜如果输入字段的值为“test”,它会说“你不能使用这个用户名”?

in your code if input is "test" ($usr == "test" - that comes from input) you echo 1, and in your code 1 means username is available? So shouldn't it be backwards?

在你的代码中如果输入是“test”($ usr ==“test” - 来自输入)你回显1,在你的代码1中意味着用户名是否可用?所以它不应该倒退吗?

Does it say "username is available" with every input?

每次输入都会说“用户名是否可用”?
