ajax - 验证时防止ajax中的＆符号破坏？

Question

function authenticate(){

    var email = '[e-mail]';
    var password = '123&567';

    var ajaxRequest;

    credentials = "cmd=login&email="+email+"&password="+password;

    var ajaxRequest = new XMLHttpRequest();
    ajaxRequest.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            alert(this.responseText);
        }
    };

    ajaxRequest.open('POST', 'http://xx', true);
    ajaxRequest.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
    ajaxRequest.send(credentials);

    return false;
}

调用函数后结果如下：

cmd=login&email="+"[e-mail]"+"&password="+"123&567";

您可以使用该功能encodeURIComponent对密码进行编码：

var email = '[e-mail]';
var password = '123&567';

var ajaxRequest;

credentials = "cmd=login&email="+email+"&password="+encodeURIComponent(password);
console.log(credentials);
/* ... */

在你的 PHP 中，你可以使用urldecode它来解码它。
