js對(duì)ajax返回?cái)?shù)組的處理介紹

本篇文章主要是對(duì)js對(duì)ajax返回?cái)?shù)組的處理進(jìn)行了詳細(xì)的介紹，需要的朋友可以過來參考下，希望對(duì)大家有所幫助

引言：
ajax異步傳輸，可以傳輸字符串，但是數(shù)組這樣的數(shù)據(jù)，就不太好傳遞了，這個(gè)時(shí)候怎么辦呢？

答案是可以通過json來處理，后臺(tái)將數(shù)據(jù)數(shù)據(jù)進(jìn)行json編碼！

然后客戶端，通過js來進(jìn)行解析。

這樣問題就解決了！json是一種很好的數(shù)據(jù)格式！

我做的是異步判斷某堂課是否處于上課狀態(tài)，會(huì)從后臺(tái)接口中獲取數(shù)組數(shù)據(jù)！共四堂課，

代碼如下：

復(fù)制代碼代碼如下:

function ajaxcheckedlessonsAction(){
        //3583 語文 8班 
        //1500 語文 9班 
        //2717 物理 8班
        //1612 物理 9班
        $whereLessons = array();
        $whereLessons['lessons.id IN(?)'] = array(3583, 1500, 2717, 1612);
        $daoLessons = new dao_lessons();
        $alllessons = $daoLessons->getLessons($whereLessons);
        //print_r($alllessons);exit;
        $lessonsChecked = array();
        foreach ($alllessons as $lessons) {
            if ($lessons['id'] == 3583) {
                $lessonsChecked['8yuwen'] = $this->verifyCheckedLessons($lessons['startime'], $lessons['endtime']);
            } elseif ($lessons['id'] == 1500) {
                $lessonsChecked['9yuwen'] = $this->verifyCheckedLessons($lessons['startime'], $lessons['endtime']);
            } elseif ($lessons['id'] == 2717) {
                $lessonsChecked['8wuli'] = $this->verifyCheckedLessons($lessons['startime'], $lessons['endtime']);
            } elseif ($lessons['id'] == 1612) {
                $lessonsChecked['9wuli'] = $this->verifyCheckedLessons($lessons['startime'], $lessons['endtime']);
            }
        }
        $json = json_encode($lessonsChecked);
        echo $json;
    }

接口處理數(shù)據(jù)，將數(shù)據(jù)json化，

前臺(tái)對(duì)json數(shù)據(jù)進(jìn)行解析

復(fù)制代碼代碼如下:

//進(jìn)入頁面就進(jìn)行的處理
        $.ajax({
            type: "POST",
            url:"/default/index/ajaxcheckedlessons",
            data:"",
            success:function(response){
                if(response){
                    var data = eval('('+response+')');
                    if(data['8yuwen']){
                      $("#8yuwen").attr("style","color:red;");
                    }else{
                      $("#8yuwen").attr("style","");  
                    }
                    if(data['8wuli']){
                      $("#8wuli").attr("style","color:red;");
                    }else{
                      $("#8wuli").attr("style","");  
                    }
                    if(data['9yuwen']){
                      $("#9yuwen").attr("style","color:red;");
                    }else{
                      $("#9yuwen").attr("style","");  
                    }
                    if(data['9wuli']){
                      $("#9wuli").attr("style","color:red;");
                    }else{
                      $("#9wuli").attr("style","");  
                    }
                }else{
                    alert("error");
                }
            }
        });
