Article or point of view and so on like the function implementation (thinkphp)

Front-End Code:

class='btm'class='zan' id= ' {$article. ID} " href="javascript:void (0); "> Likes (<span>{$article .likescount}</span>) </a></div>

Of course, the processing of data with Ajax, but first to introduce jquery and Jquery.cookie.js, this is Baidu download it yourself. The front end uses cookies to limit the effect of repeating the likes.

JS section:

$(". Zan"). Live ('Click', function () {varoa=$ ( This); varId=oa.attr ('ID');//Get ID Property        varVl=oa.find ("span"). text (); VL=parseint (VL) +1; if(!$.cookie (ID)) {            //Console.log (' no cache ');$.post ("{: U ("Article/zan")}", {id:id},function (data) {Console.log (data)if(data.status=='OK') {alert ('+1 likes');//simulate asynchronous data plus 1$.cookie (Id,id);//change the flag initial value to ensure that the function executes only onceOa.find ("span"). Text (VL);//page element plus 1                }            },'JSON'); }Else{            //Console.log (' with cache ');Alert'you've already ordered it!'); }        return false; })

Back end receive data: IndexController.class.php

 Public function Zan () {      $data [' id ']=isset ($_post[' id '))? Intval (Trim ($_post[' id ')):0;      $db=M (' article ');       = $db,where($data),setinc (' Zan ');       if ($res) {        $this->ajaxreturn ($data, ' OK ',1);        Exit ();      } Else {        $this->ajaxreturn ($data, ' fail ',0);        Exit ();      }    }

Jquery.cookie.js:
