使用Javascript从PHP解析JSON并将值动态推送到数组中

Question

i got an array :

var sampleitems =[];

i get json data from url which returns values

 WinJS.xhr({
        type: "GET",
        url: "http://some_webpage.php", 

    }).then(function (success) { 
// DYNAMICALLY PUSH CONTENTS TO ARRAY 'sampleitems'
    }, 
  function (error) {
      document.getElementById("check").innerText = "vada pochu";
  }

i need the array to look like:

var sampleitems = [
{ key: "group1", title: "Group Title: 1", subtitle: "Group Subtitle: 1", backgroundImage: darkGray, description: groupDescription } ];

How can i add values to the sample items dynamically and how my PHP page should return JSON in which format ?

Answer 1

You should look at PHP's JSON_ENCODE() function. The code below should output the JSON that you need (I haven't checked that it works).

$sampleitems=array(
 array(
  'key'=>'group1',
  'title'=>'Group Title: 1',
  ...
 )
);

echo json_encode($sampleitems);

Answer 2

sampleitems.push（{键：“ group1”，标题：“ Group标题：1”，字幕：“ Group字幕：1”，backgroundImage：darkGray，描述：groupDescription}）;

Answer 3

make an array an perform json_encode like:

$sampleitems = array(
        'key' => 'group1',
        'title' => 'Group Title: 1',
        'subtitle' => 'Group Subtitle: 1',
        'backgroundImage' => 'darkGray',
        'description' => 'groupDescription'
    );
    echo '['.json_encode($sampleitems).']';

result:

[{"key":"group1","title":"Group Title: 1","subtitle":"Group Subtitle: 1","backgroundImage":"darkGray","description":"groupDescription"}]
