在angularjs codemirror中显示json对象

Question

I have a json object and want to display it on codemirror using angularjs codemirror but it got an error saying ui-codemirror cannot use an object or an array as a model . Then I tried to convert the object into string using JSON.stringify , the string does not format nicely in codemirror. Anyone can help me to figure out how to make my code in formatted nicely in codemirror? Thanks

ex:

//inside javascript

    $scope.code = {
        "name": "user1",
        "id": "34",
        "value": [3, 5, 4]
    };

     $scope.editorOptions = {
          lineWrapping : true,
          lineNumbers: true,
          mode: 'application/json',
        };

//inside html
<ui-codemirror ui-codemirror-opts="editorOptions" ng-model="code"></ui-codemirror>

It returns an error for this: ui-codemirror cannot use an object or an array as a model

if I change to JSON.stringify($scope.code) , code mirror display like this:

{"name":"user1","id":"34","value":[3,5,4]}

However, I want it to display as this:

{

  "name": "user1", "id": "34", "value": [3, 5, 4] } 

Any help? Thanks

You can specify the indentation:

$scope.codeView = JSON.stringify($scope.code, null, 4);
