Thinkphp method to receive JSON data using AJAX _php instance

The examples in this article describe the methods used to receive JSON data using Ajax in thinkphp. Share to everyone for your reference. The specific analysis is as follows:

Here through the thinkphp+jquery implementation of Ajax, extended the next, wrote a query, the foreground code is as follows:

First you need to introduce Jquery.js, the main code is as follows:

 code as follows:

function Ajax (Id,pic) {
Since thinkphp does not parse the thinkphp constants in JavaScript, it needs to be defined here first.
var url= ' __url__ ';
$.ajax ({
url:url+ '/returnajax/id/' +id,//submit access URL
Type: ' Get ',//Submit method
DataType: ' text ',//Return of the type of content, because the PHP file is directly echo, then this is the text
timeout:1000,//Timeout time
Error:function () {//If error, execute function
Alert (' Error loading XML document ');
},
Success:function (data) {
alert (data);//If successful, eject
WriteHTML (Data,pic);
}
});
}
function writehtml (data,pic) {
var product = eval (' (' + data + ') '); Can be turned into a JSON object even without introducing json.js
Alert ($ ("#cate_pic"). attr ("src"));
$ ("#cate_pic"). attr ("src", ". /images/"+pic);
$ ("#product_pic"). attr ("src", ". /attachments/product/"+product.attachpath+"/"+product.attachthumb");
$ ("#product_subject"). HTML (product.subject);
$ ("#product_content"). HTML (product.content);
}

The echo output is used in Product.class.php, and the Json_encode () method in thinkphp can automatically convert an object to JSON format

Copy Code code as follows:

Public Function Returnajax () {
$id = $_get[' id '];
$Product =d (' Product ')->where (' id= '. $id)->find ();
Returns a data set in JSON format
echo Json_encode ($Product);
Print_r (Json_encode ($Product));
}

The data format returned is as follows:

Copy Code code as follows:

{
"id": "9",
"userid": "1",
"CID": "10",
"CID": "10",
"Subject": "1111",
"Color": "",
"Spec": "",
"Size": "",
"keywords": "",
"Content": "<p>1111</p>",
"Meno": "1111",
"Attachpath": "200903",
"Attachment": "49d1d86e68d31.png",
"Attachthumb": "49d1d86e68d31_thumb.png"
}
