HTTP 错误 405.0 - 不允许使用 Jquery ajax get 的方法

我正在开发一个表单，用户必须在其中插入用户名。我想检查模糊用户的用户名是否有效：

我添加了此脚本：

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.9/jquery-ui.min.js"></script>

IN HTML：

<input name="username" type="text" onblur="checkUsername()">

脚本：

function checkUsername(){
    var usn = document.getElementsByName('username')[0];
    if(usn.value != "") {
       var html = $.ajax({
       type: "GET",
       url: "checkUsername.php?",
       data: "usr=" +usr.value 
       async: false,
       dataType: "text"}).responseText;   
       if(html == "si") {
          usn.style.backgroundColor = "green";
       } else {
          usn.style.backgroundColor = "red";
          usn.value = "Username still exists!";
       }
    }
}

所以 onBlur 不起作用，当我提交表单时，会出现如下错误：

HTTP Error 405.0 - Method Not Allowed
The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.

什么我可以做什么吗？问题出在哪里？

I'm developing a form in which user must insert an username. I want to check on blur that username of user is valid:

I added this script:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.9/jquery-ui.min.js"></script>

IN HTML:

<input name="username" type="text" onblur="checkUsername()">

Script:

function checkUsername(){
    var usn = document.getElementsByName('username')[0];
    if(usn.value != "") {
       var html = $.ajax({
       type: "GET",
       url: "checkUsername.php?",
       data: "usr=" +usr.value 
       async: false,
       dataType: "text"}).responseText;   
       if(html == "si") {
          usn.style.backgroundColor = "green";
       } else {
          usn.style.backgroundColor = "red";
          usn.value = "Username still exists!";
       }
    }
}

So onBlur doesn't work, and when I submit form it appear an error like this:

HTTP Error 405.0 - Method Not Allowed
The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.

What can I do? Where is the problem?

首先考虑将您的 JQuery 升级到 1.6.x 版本。

尝试修改脚本的版本：

function checkUsername(){
    var usn = document.getElementsByName('username')[0];
    if(usn.value != "") {
       var html = $.ajax({
       url: "checkUsername.php",
       data: "usr=" +usr.value 
       async: false,
       dataType: "text"}).responseText;   
       if(html == "si") {
          usn.style.backgroundColor = "green";
       } else {
          usn.style.backgroundColor = "red";
          usn.value = "Username still exists!";
       }
    }
}

First of all consider upgrading your JQuery to 1.6.x version.

Try this modified version of your script:

function checkUsername(){
    var usn = document.getElementsByName('username')[0];
    if(usn.value != "") {
       var html = $.ajax({
       url: "checkUsername.php",
       data: "usr=" +usr.value 
       async: false,
       dataType: "text"}).responseText;   
       if(html == "si") {
          usn.style.backgroundColor = "green";
       } else {
          usn.style.backgroundColor = "red";
          usn.value = "Username still exists!";
       }
    }
}

通常，当我从 Jquery 运行 AJAX 命令时，我的数据属性是一个像这样的数组：

 $.ajax({
    type: "GET",
    url: "checkUsername.php",
    data: {
        usr: usr.value 
    },
   async: false,
   dataType: "text"}).responseText;

Usually when I run an AJAX command from Jquery, my data attribute is an array like such:

 $.ajax({
    type: "GET",
    url: "checkUsername.php",
    data: {
        usr: usr.value 
    },
   async: false,
   dataType: "text"}).responseText;
