如何通过Ajax将PHP输出返回到页面？
[英]How to get my PHP output back to a page via Ajax?
问题描述
I'm trying to get a response back from a php script, so I dont have to reload the page and display some animations. 
我正在尝试从php脚本获取响应，因此我不必重新加载页面并显示一些动画。
I have both parts working, but when I try to put them together, nothing works. 我的两个部分都在工作，但是当我尝试将它们放在一起时，没有任何效果。
Right now I send the input data via Ajax, but I can't bring the results back. 现在，我通过Ajax发送输入数据，但无法将结果返回。
Please help me, thanks in advance. 请帮助我，在此先感谢。

I think that all you need is to fix the PHP script and fix the response from your Ajax call. 我认为您所需要的只是修复PHP脚本并修复来自Ajax调用的响应。
First of all, you PHP need and 'echo' statement to print some output. 首先，您的PHP需要使用'echo'语句来打印一些输出。 The output will be passed to the response from the ajax call, than JS have some material to work on. 输出将传递给ajax调用的响应，而不是JS需要处理的材料。
An example: 一个例子：
<?php echo $info; ?>
After fix the php, try to edit this JS part: 修复php后，尝试编辑此JS部分：
$.ajax({
type: "post",
url: "scripts/search.php",
data: dataString,
success: function(data) {
console.log(data);
}
});
If you PHP script return to you an HTML markup or print HTML, you can use the .append() or .prepend() functions from jQuery to append the data on the body like: 如果您的PHP脚本返回HTML标记或打印HTML，则可以使用jQuery中的.append（）或.prepend（）函数将数据追加到正文中，例如：
$.ajax({
type: "post",
url: "scripts/search.php",
data: dataString,
success: function(data) {
$('body').append(data);
}
});
To show some CSS animation, I think you need to use .addClass() to the element you want to animate. 为了显示一些CSS动画，我认为您需要对要设置动画的元素使用.addClass（）。

Problem is your the post data that you are sending. 问题是您发送的帖子数据。 Change 更改
var dataString = document.getElementById("searchBox").value;
To 至
var dataString = $("#searchbar").serialize();
Your search.php is expecting a value in $_POST['searchBox'] 您的search.php需要$ _POST ['searchBox']中的值
if(isset($search)){...
but never finds it so its skips that whole process of the search 但从未找到它，因此它跳过了整个搜索过程
