Question

我正在使用ajax加载一个基于屏幕分辨率显示内容的php脚本。该脚本运行良好，但ajax调用的url也会在稍后的脚本中调用 - 它包含所有处理信息。因此，结果是所有内容都通过jquery加载，然后与php重复。例如：

<script type="text/javascript">
$(document).ready(function() {
      $.ajax({
         url: 'functions/maxresults.php',
         type: 'GET',
         data: {h: screen.height, w: screen.width}
      }).done(function ( data ) {
          alert("I am working!");
         document.getElementById("container").innerHTML=data;
        });
    });
</script>

进一步向下

<?php
include_once("functions/maxresults.php");   
?>

<?php
require_once("databasefunctions.php");
?>

<div id="container">
<div id="movieinfo"> 
<?php include("sidebar.php");?>
<?php
// get the function
include_once ('function.php');
if($_GET['page'])
$page = $_GET['page'];
else
$page = 0; 
$maxresults = -1;
if(($_GET['w']) && ($_GET['h'])) {
  $w = $_GET['w'];
  $h = $_GET['h'];
}
  if ($w == 1920) {
    $maxresults = 24;  
  } else if ($w == 1600) {
    $maxresults = 21;  
  } else if ($w == 1440){ 
    $maxresults = 14;
  } else if ($w == 1366) { 
    $maxresults = 21;
  } else if ($w == 1024) {
    $maxresults = 8;
  } else 
    $maxresults = 6;
echo $maxresults;
$currentpage = $page;
$page = $page*$maxresults;
$numpages = QuickQuery("SELECT COUNT(id) FROM movies WHERE visible=1");
$numpages = mysql_result($numpages, 0);
$numpages = $numpages/$maxresults-1;
$result = GetMoviesByRangeID($page, $maxresults);//Show <maxresults> pages at a time
DisplayResults($result); 
?>
</div>
</div>

我无法删除php include或脚本根本不起作用。是否会在jquery工作中创建include_once，如果是，我该如何编写它？

Answer 1

PHP是一个预处理器。因此，您在文件中“稍后”包含它并不重要。在执行JavaScript之前，将处理并输出您的include_once。

我看起来问题是你的include_once脚本也在输出容器div。因此，当您删除该行时，它会破坏javascript。试试这个：

从您的maxresults.php文件中删除容器div。
将<?php include_once('functions/maxresults.php);>替换为ID为容器的空div：<div id="container"></div>

您的JavaScript现在应该可以使用：

<script type="text/javascript">
$(document).ready(function() {
  $.ajax({
     url: 'functions/maxresults.php',
     type: 'GET',
     data: {h: screen.height, w: screen.width}
  }).done(function(resp) {
      alert("I am working!");
      $("#container").html(resp);
    });
});
</script>

<div =id="container"></div>

<强> maxresults.php

<?php
require_once("databasefunctions.php");
?>

<div id="movieinfo"> 
<?php include("sidebar.php");?>
<?php
// get the function
include_once ('function.php');
if($_GET['page'])
$page = $_GET['page'];
else
$page = 0; 
$maxresults = -1;
if(($_GET['w']) && ($_GET['h'])) {
  $w = $_GET['w'];
  $h = $_GET['h'];
}
  if ($w == 1920) {
    $maxresults = 24;  
  } else if ($w == 1600) {
    $maxresults = 21;  
  } else if ($w == 1440){ 
    $maxresults = 14;
  } else if ($w == 1366) { 
    $maxresults = 21;
  } else if ($w == 1024) {
    $maxresults = 8;
  } else 
    $maxresults = 6;
echo $maxresults;
$currentpage = $page;
$page = $page*$maxresults;
$numpages = QuickQuery("SELECT COUNT(id) FROM movies WHERE visible=1");
$numpages = mysql_result($numpages, 0);
$numpages = $numpages/$maxresults-1;
$result = GetMoviesByRangeID($page, $maxresults);//Show <maxresults> pages at a time
DisplayResults($result); 
?>
</div>

javascript include_once- javascript php调用相同的文件复制内容
