ThinkPHP implements an example of the ajax function similar to the search function on the official website, thinkphpajax

This article describes how ThinkPHP implements the ajax search function on the official website. Share it with you for your reference.

The specific implementation method is as follows:

Background code:
Copy codeThe Code is as follows: // search, if 1 is not 0
Function search (){
$ Keyword = $ _ POST ['search'];
$ Goods = M ('goods ');
// Here I make a fuzzy query to the name or corresponding id, mainly because my system is
// Directly view the product ID in the mall System
$ Map ['goods _ id | goods_name '] = array ('like',' % '. $ keyword.' % ');
// Pass the query condition into the query method
If ($ goods = $ Goods-> where ($ map)-> select ())
{
$ This-> ajaxReturn ($ goods, 'query successful! ', 1 );
} Else {
$ This-> ajaxReturn ($ data, "query failed, data does not exist! ", 0 );
}
}
Front-end code:
Copy codeThe Code is as follows: $ (document). ready (function (){
$ (". Show_message"). hide ();
Var $ search = $ ('# search_box ');
$ ("# Submit_from"). click (function (){
If ($ ("# search_box"). attr ("value") = '')
{
// Alert ('enter the text! ');
$ (". Show_message" cmd.html ('error message: the text in the search box cannot be blank! ');
$ (". Show_message"). fadeIn (1000 );
$ (". Show_message"). fadeOut (1000 );
$ Search. focus ();
// Return false;
} Else {
// Start ajax execution data
$. Ajax ({
Type: "POST ",
Url: "/index. php/Goods/search ",
Data :{
Search: $ search. val ()
},
DataType: "json ",
Success: function (data ){
If (data. status = 1 ){
// Alert (data.info );
Var html = '';
$. Each (data. data, function (no, items ){
Html + = '';
});
Html + ="
'+ Items. goods_id + ''+ items. goods_name +'' + items. add_time + ''+ items. brand +'' + items. price + '";
$ (". Goods-list" ).html ('your .html (html );
// Alert (html );
}
Else if (data. status = 0 ){
$ (". Show_message"). show ();
$ (". Show_message" pai.html (data.info );
$ (". Show_message"). fadeOut (3000 );
// Alert (data.info );
Return false;
}
}
});
}
});
});
