如果是自定义数组的请加 [ ] 不然会报错：
Uncaught TypeError: Cannot read property 'length' of null
Uncaught TypeError: Cannot read property 'length' of undefined

public function userList(){
$arr = array(
'id' => '1',
'name' => '李三',
'pwd' => 'abc',
);
$json_string = json_encode($arr);
$data='['.$json_string.']';
$obj = json_decode($data);
$this->ajaxReturn($obj);
}数据库:public function userList(){
$User = M("User");
$arr = $User->select();
$json_string = json_encode($arr);
$obj = json_decode($json_string);
$this->ajaxReturn($obj);
} 最佳答案
