jQuery simple Ajax call example
jQuery It’s really convenient. Let’s make a simple Ajax call:
Create a simple html file:
<!DOCTYPE HTML><html><head><script type="text/javascript" src="Public/js/jquery-easyui-1.3.1/jquery-1.8.2.min.js"></script><script type="text/javascript">
$(function(){ //按钮单击时执行 $("#testAjax").click(function(){ //取Ajax返回结果
//为了简单，这里简单地从文件中读取内容作为返回数据 htmlobj=$.ajax({url:"/Readme.txt",async:false}); //显示Ajax返回结果 $("#myp").html(htmlobj.responseText);
});
});</script> </head>
<body>
<p id="myp"><h2>通过 AJAX 改变文本</h2></p>
<button id="testAjax" type="button">Ajax改变内容</button>
</body></html>Okay, click the button to see the effect.
Of course, jQuery's Ajax call can control many items, and a simple call is demonstrated here.
Pay attention to your own jqueryreferencepath.
Okay, let’s do an example of calling the background:
<!DOCTYPE HTML><html><head><script type="text/javascript" src="Public/js/jquery-easyui-1.3.1/jquery-1.8.2.min.js"></script><script type="text/javascript">
$(function(){ //按钮单击时执行 $("#testAjax").click(function(){
//Ajax调用处理
var html = $.ajax({
type: "POST",
url: "test.php",
data: "name=garfield&age=18",
async: false
}).responseText;
$("#myp").html('<h2>'+html+'</h2>');
});
});</script> </head>
<body>
<p id="myp"><h2>通过 AJAX 改变文本</h2></p>
<button id="testAjax" type="button">Ajax改变内容</button>
</body></html>Backend code:
<?php $msg='Hello,'.$_POST['name'].',your age is '.$_POST['age'].'!'; echo $msg;
Now you can get data from the background!
Of course, we can also call Ajax like this:
<!DOCTYPE HTML><html><head><script type="text/javascript" src="Public/js/jquery-easyui-1.3.1/jquery-1.8.2.min.js"></script><script type="text/javascript">
$(function(){ //按钮单击时执行 $("#testAjax").click(function(){
//Ajax调用处理 $.ajax({
type: "POST",
url: "test.php",
data: "name=garfield&age=18",
success: function(data){
$("#myp").html('<h2>'+data+'</h2>');
}
});
});
});</script> </head>
<body>
<p id="myp"><h2>通过 AJAX 改变文本</h2></p>
<button id="testAjax" type="button">Ajax改变内容</button>
</body></html>
Note that the data parameter in
success: function(data)
can be changed to another name, such as success: function( msg), msg(data) is the returned data. This is the parameter of the callback function, not the data parameter in the Ajax call in
data: "name=garfield&age=18"
.

PHP vs. Ajax: Solutions for creating dynamically loaded content

Ajax (Asynchronous JavaScript and XML) allows adding dynamic content without reloading the page. Using PHP and Ajax, you can dynamically load a product list: HTML creates a page with a container element, and the Ajax request adds the data to that element after loading it. JavaScript uses Ajax to send a request to the server through XMLHttpRequest to obtain product data in JSON format from the server.

Clicking the button triggers an Ajax request to load the product list.
