Angularjs convert string to object inside ng-repeat - json

Question

i've got a string saved in my db
{"first_name":"Alex","last_name":"Hoffman"}
I'm loading it as part of object into scope and then go through it with ng-repeat. The other values in scope are just strings
{"id":"38","fullname":"{\"first_name\":\"Alex\",\"last_name\":\"Hoffman\"}","email":"alex#mail","photo":"img.png"}
But I want to use ng-repeat inside ng-repeat to get first and last name separate
<div ng-repeat="customer in customers">
<div class="user-info" ng-repeat="name in customer.fullname">
{{ name.first_name }} {{ name.last_name }}
</div>
</div>
And I get nothing. I think, the problem ist, that full name value is a string. Is it possible to convert it to object?

Answer 1

First off... I have no idea why that portion would be stored as a string... but I'm here to save you.
When you first get the data (I'm assuming via $http.get request)... before you store it to $scope.customers... let's do this:
$http.get("Whereever/You/Get/Data.php").success(function(response){
//This is where you will run your for loop
for (var i = 0, len = response.length; i < len; i++){
response[i].fullname = JSON.parse(response[i].fullname)
//This will convert the strings into objects before Ng-Repeat Runs
//Now we will set customers = to response
$scope.customers = response
}
})
Now NG-Repeat was designed to loop through arrays and not objects so your nested NG-Repeat is not necessary... your html should look like this:
<div ng-repeat="customer in customers">
<div class="user-info">
{{ customer.fullname.first_name }} {{ customer.fullname.last_name }}
</div>
This should fix your issue :)

You'd have to convert the string value to an object (why it's a string, no idea)
.fullname = JSON.parse(data.fullname); //replace data.fullname with actual object
Then use the object ngRepeat syntax ((k, v) in obj):
<div class="user-info" ng-repeat="(nameType, name) in customer.fullname">
{{nameType}} : {{name}}
</div>

My advise is to use a filter like:
<div class="user-info"... ng-bind="customer | customerName">...
The filter would look like:
angular.module('myModule').filter('customerName', [function () {
'use strict';
return function (customer) {
// JSON.parse, compute name, foreach strings and return the final string
};
}
]);

I had same problem, but i solve this stuff through custom filter...
JSON :
.........
"FARE_CLASS": "[{\"TYPE\":\"Economy\",\"CL\":\"S \"},{\"TYPE\":\"Economy\",\"CL\":\"X \"}]",
.........
UI:
<div class="col-sm-4" ng-repeat="cls in f.FARE_CLASS | s2o">
<label>
<input type="radio" ng-click="selectedClass(cls.CL)" name="group-class" value={{cls.CL}}/><div>{{cls.CL}}</div>
</label>
</div>
CUSTOM FILTER::
app.filter("s2o",function () {
return function (cls) {
var j = JSON.parse(cls);
//console.log(j);
return j;
}
});
