如何从json文档打印列表

Posted 2021-04-09

我想从list.json文件打印我的数据

    xmlhttp=new XMLHttpRequest();
    xmlhttp.open("GET","list.json",false);
    xmlhttp.send();
    var list = xmlhttp.responseText;

这是我的名单。杰森

{

"p1": {
    "name":"fruit song",
    "cat":"learning",
    "lan":"eng",
    "ur":"abc1"
},
"p2": {
    "name":"eting sugar",
    "cat":"random",
    "lan":"eng",
    "ur":"abc2"
},
"p3": {
    "name":"salgira ka din",
    "cat":"birthday",
    "lan":"urdu",
    "ur":"abc3"
},
"p4": {
    "name":"twinkle twinkle",
    "cat":"random",
    "lan":"eng",
    "ur":"abc4"
},
"p5": {
    "name":"abc song",
    "cat":"learning",
    "lan":"eng",
    "ur":"abc5"
}

}

我得到的数据就像

obj = JSON.parse(list);
$scope.n =obj.p1.name;
$scope.c =obj.p1.cat;
$scope.l =obj.p1.lan;
$scope.u =obj.p1.ur;

这工作正常，并在alert（$ scope.n）中显示数据;

我想用html打印这个json文件

p1名称：{{n}}类别：{{c}}语言：{{l}}

p2名称：{{n}}类别：{{c}}语言：{{l}}

在list.json里面会有50多个P1类型的记录。

谁能告诉我代码打印html中的所有记录

答案

你应该使用AngularJS的ng-repeat，比如

<div>
  <p ng-repeat="(key, val) in obj">{{key}} name: {{val.name}} category : {{val.cat }} language : {{val.lan}}</p>
</div>

对于将来的参考，请使用AngularJS文档：ngRepeat

另一答案

所以我的HTML是

<li ng-repeat="item in items"   item="item" ng-click="model.itemValue = item" >
<div class = "row" style="background: url(img/4.jpg) no-repeat center;background- 
size:cover;">
<div class = "col"><h3>{{name}} :)</h3></div>
<div class = "col col-60"><h3>{{email}}</h3></div>
<div class = "col"><h3><button class="button button-calm button rdm">PLAY</button> 
</h3></div>
</div>
</li>

我的控制器是

 xmlhttp=new XMLHttpRequest();
 xmlhttp.open("GET","Ulist.json",false);
 xmlhttp.send();
 var list = xmlhttp.responseText;
 obj = JSON.parse(list);

 $scope.data = {};

 $scope.model = {};

 $scope.items = obj;

这对我有用
