"ajax:成功"；被叫两次 [英] "ajax:success" being called twice

问题描述

我正在使用jquery_ujs发送一个简单的帖子请求.我将回调函数绑定到"ajax:success"事件.但是，此回调对于每个成功的帖子都会被调用两次.

I'm using jquery_ujs to send a simple post request. I bound a callback function to the "ajax:success" event. However, this callback is being called twice for each successful post.

我知道这类似于其他问题，但是我检查了我的源代码，它似乎没有两次加载jquery_ujs.js文件(许多响应都建议).

I know this is similar to this other question, but I checked my source and it doesn't appear to be loading the jquery_ujs.js file twice (as suggested by many of the responses).

    $(".new_item").bind("ajax:success", 
    function(xhr, data, status) 
    {
                 /* this is called twice for each call!*/
    }

有人有指针吗?谢谢！

推荐答案

正在发生一些事情.

要么您拥有.new_item类的多个元素

Either you have multiple elements with .new_item class

alert($(".new_item").length);

您两次发送了ajax请求

you are sending the ajax request twice

alert("Sending Request");
$.ajax(...

或者您将事件绑定两次

alert("Binding Event");
$(".new_item").bind("ajax:success", function(xhr, data, status) {

注意:如果您使用的是现代浏览器，请使用console.log()
