Javascript Ajax调用是在页面上的其他位置插入数据
我正在使用ajax调用在页面的开头插入数据。这更像是一个墙贴脚本。每当用户发布内容时，最新发布的内容都会显示在“发布”页面的顶部 我正在使用JS、PHP和HTML页面 以下是我的js代码：Javascript Ajax调用是在页面上的其他位置插入数据,javascript,php,jquery,html,ajax,Javascript,Php,Jquery,Html,Ajax,我正在使用ajax调用在页面的开头插入数据。这更像是一个墙贴脚本。每当用户发布内容时，最新发布的内容都会显示在“发布”页面的顶部 我正在使用JS、PHP和HTML页面 以下是我的js代码： $(function() { $("#tweet_submit").click(function() { var tweet = $("#tweet").val(); var x = $('.preview').attr('id'); if(x) va

您的输入帮助了我，我能够解决它。内容在两个位置被调用，ajax在第一个位置插入数据，而我没有将数据放在我需要的位置
谢谢。内容似乎被插入到了#content
元素pffffff的顶部。说真的，这相当于250行代码，javascript和HTML甚至没有缩进。帮助我们帮助您：请缩小代码范围并缩进。。。
