ajax jquery xml

1,Content-Type
Many times the failure to parse is a problem with Content-Type.
If it is an xml file, please skip this step
The dynamically generated XML must be set to text/xml, otherwise it will default to text/html, which is ordinary text.
Content-Type settings for common languages
Copy code The code is as follows:

header( "Content-Type:text/xml"); //php
response.ContentType="text/xml" //asp
response.setHeader("ContentType","text/xml"); //jsp

2, xml structure.

Example:
Wrong XML
Copy code The code is as follows:

CODE:

zhangsan1
lisi
2
Correct
CODE:



zhangsan
1


lisi< ;/name>
2



3, parse
Here refers to macnie's
traversing students (the above XML is still used here, the child node is student)
Copy code The code is as follows:

$.ajax({
url:'ajax.asp',
type: 'GET',
dataType: 'xml',//here You don’t have to write it, but don’t write text or html!!!
timeout: 1000,
error: function(xml){
alert('Error loading XML document' xml);
} ,
success: function(xml){
$(xml).find("student").each(function(i){
var id=$(this).children("id") ; //Get the object
var id_value=$(this).children("id").text(); //Get the text
alert(id_value);//Here is the value of the ID.
alert($(this).attr("email")); //The email attribute under student can be displayed here.
//The last output, this is the writing method of cssrain, which seems to be more elegant than macnie
$('
  • ')
    .html(id_value)
    .appendTo('ol');
    });
    }
    });

    One last thing to add: Make sure the server is encoded in utf-8

    PHP vs. Ajax: Solutions for creating dynamically loaded content PHP vs. Ajax: Solutions for creating dynamically loaded content Jun 06, 2024 pm 01:12 PM

    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. PHP uses MySQL to query product data from the database and encode it into JSON format. JavaScript parses the JSON data and displays it in the page container. Clicking the button triggers an Ajax request to load the product list.
