Question

我将jquery更新为旧文件中的新版本，该文件添加了一些新功能。现在jquery ajax帖子已停止工作了。我已经尝试过改变成功，但这并没有解决问题。

// check email in database
$("#email_address").change(function () //this function needs tidying up!
{ //if theres a change in the email textbox

    var email_address = $("#email_address").val(); //Get the value in the username textbox
    if (email_address.length > 3) //if the lenght greater than 3 characters
    {
        $("#availability_status").html('<img src="../img/loader.gif" align="absmiddle"> Checking this email is not already registered<br />'); //Add a loading image in the span id="availability_status"

        $.ajax({ //Make the Ajax Request
            type: "POST",
            url: "../ajax_check_email.php", //file name
            data: "email_address=" + email_address, //data
            success: function (server_response) {

                $("#availability_status").ajaxComplete(function (event, request) {

                    if (server_response == '0') //if ajax_check_email.php return value "0"
                    {
                        $("#availability_status").css("display", "none");
                    } else if (server_response == '1') //if it returns "1"
                    {
                        $("#availability_status").css("display", "inline");
                        $("#availability_status").html('<font color="red">This email address is already registered in our database. </font>');
                    }

                });
            }

        });

    }

    return false;
});

我猜这是：

http://api.jquery.com/ajaxComplete/：

＆＃34;从jQuery 1.8开始，.ajaxComplete（）方法只应附加到文档。＆＃34;

但是，我不确定为什么会这样开始。您应该可以完全删除ajaxComplete部分：

success: function (server_response) {

    if (server_response == '0') //if ajax_check_email.php return value "0"
    {
        $("#availability_status").css("display", "none");
    } else if (server_response == '1') //if it returns "1"
    {
        $("#availability_status").css("display", "inline");
        $("#availability_status").html('<font color="red">This email address is already registered in our database. </font>');
    }

}

Answer 2

应该足够了：

$( document ).ajaxComplete(

Answer 3

从jQuery 1.8开始，.ajaxComplete()方法只应附加到文档，例如：

$(document).ajaxComplete(function() {
    // do something on complete
});

请参阅documentation。

您的AJAX请求中有一个ajaxComplete()方法。您是否可以像complete()回调一样使用success()回调？

$.ajax({
    type: "POST",
    url: "../ajax_check_email.php", //file name
    data: "email_address=" + email_address, //data
    success: function() {
        // do something
    },
    complete: function() {
        // do something
    }
});

Ajax请求适用于旧版本的jquery而不是新版本
