PHP for循环与AJAX div自动刷新

时间：2015-10-19 23:38:41

标签： php ajax

我的代码的问题是当我在for循环中打印php ajax div时，当循环有2个索引时，我得到一个循环索引。

我的代码示例：

的index.php 

<html>
<head>
<title>DeportesRulz.com</title>
<link charset="utf-8" href="./css/tablaodds.css" media="screen" rel="stylesheet" type="text/css" />
<script>
            function AJAX(){
            try{
            xmlHttp=new XMLHttpRequest(); // Firefox, Opera 8.0+, Safari
            return xmlHttp;
            }
            catch (e){
            try{
            xmlHttp=new ActiveXObject('Msxml2.XMLHTTP'); // Internet Explorer
            return xmlHttp;
            }
            catch (e){
            try{
            xmlHttp=new ActiveXObject('Microsoft.XMLHTTP');
            return xmlHttp;
            }
            catch (e){
            alert('Your browser does not support AJAX.');
            return false;
            }
            }
            }
            }

我尝试将代码放在循环ajax中但我无法使其工作。

file1.php 

echo htmlspecialchars($_GET["row"]);

抱歉我的错误解释...在ajax代码更改中：

var url = "./file1.php?row=[$k]";

并在循环中添加。

我的代码不好：/

1 个答案:

答案 0 :(得分：0)

请认真对待这个建议：阅读有关编程的更多信息。特别是基本知识，如：变量，函数和范围。如果您要继续使用javascript，请了解闭包（在学习其他内容之后）。

我认为你试图让PHP代码为每个“live”div打印一个单独的函数。您可以将div作为函数的参数，然后为每个div调用该函数。

我在代码中添加了一些关于代码的注释。请务必在阅读后将其删除（除非您发现它们对记忆有用：）

$('#<%= dom_id(@post) %>').replaceWith("<%= j render partial 'calendars/post_partial', object: @post %>");
