This article mainly introduces in detail how to use the php plug-in Xajax, which has certain reference value. Interested friends can refer to it

Xajax is a PHP plug-in without refreshing or jumping to other Page, the technology that can interact with the backend database by clicking components etc.

Xajax is a plug-in of php. If you want to use Xajax, you must first download a compressed package from its official website. The Internet speed is slow, so I also uploaded one for everyone (click to open the link: https://pan.baidu.com/s/1gfkY3mj Password: bcvu), and everyone chooses to download it.

After downloading xajax_0.5_minimal.zip, put the contents into the project directory you want to develop. For example, the author's project directory is C:\PHPnow-1.5.6\htdocs\myphp\xajax

##xajaxhello.php, xjaxreg.php, xajaxregsuc.php are pages developed by the author. They are placed here to illustrate the folder xajax_core, xajax_js file copyright. inc.php must be placed in the project directory. Do not try to create another folder and place the folder xajax_core, xajax_js file copyright.inc.php in it. This is theoretically fine, but an error occurs during the following operation.

For example, the following xajax helloworld code:

<?php 
include &#39;xajax_core/xajax.inc.php&#39;; 
$xajax=new xajax(); 
$xajax->registerFunction("myfunction"); 
function myfunction($text){ 
 $orps=new xajaxResponse(); 
 $orps->alert("helloworld!"); 
 $orps->assign("p","innerHTML",$text); 
 return $orps; 
 } 
$xajax->processRequest(); 
$xajax->printJavascript(); 
?> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title>xajax</title> 
</head> 
 
<body> 
<p id="p"></p> 
<button onclick="xajax_myfunction(&#39;hello world&#39;);">ok</button> 
</body> 
</html>

For example, if you create a new folder xajax and put the folder xajax_core, The xajax_js file copyright.inc.php is placed inside, even if you change the second line in the helloworld code above, change include 'xajax_core/xajax.inc.php'; to include 'xajax/xajax_core/xajax.inc.php';

An error will also be reported during actual operation, and the following dialog box will pop up:

The entire program cannot be run!

Therefore, be sure to place the folder xajax_core, xajax_js file copyright.inc.php under the project directory. Anyway, there are only three files.

Let’s explain the above helloworld code,

<?php 
include &#39;xajax_core/xajax.inc.php&#39;; 
//指定动作 
$xajax=new xajax(); 
//相当于声明一个xajax处理函数myfunction 
$xajax->registerFunction("myfunction"); 
 
function myfunction($text){ 
 //指定动作 
 $orps=new xajaxResponse(); 
 //调用orps中的alert方法，弹出helloworld对话框 
 $orps->alert("helloworld!"); 
 //调用orps中的assign方法，指定id为p的p的内文本为传过来的text参数 
 $orps->assign("p","innerHTML",$text); 
 //以下是指定动作 
 return $orps; 
 } 
$xajax->processRequest(); 
$xajax->printJavascript(); 
?> 
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title>xajax</title> 
</head> 
 
<body> 
<p id="p"></p> 
<!--html部分关键是这里，说明我要调用xajax函数myfunction，且参数为helloworld--> 
<button onclick="xajax_myfunction(&#39;hello world&#39;);">ok</button> 
</body> 
</html>

So the running result of this xajaxhello.php is ：

When the page is loaded first, there is only one ok, and then when I click ok, it interacts with xajax. The helloworld dialog box pops up, and then, set the inner text of p with id as p to helloworld!

Click again to repeat this action.
