How to convert input ng-list text to JSON objects.

Answer 1

Write your own directive
app.directive('jsonConvert', function(){
return {
require: 'ngModel',
link: function (scope, elm, attrs, ngModel){
scope.$watch(
function(){
return ngModel.$modelValue;
}, function(newValue, oldValue){
var value = ngModel.$modelValue
if (value instanceof Array) return;
var valueArr = value ? value.split(',') : value;
if (!valueArr) return;
for (var i = 0; i < valueArr.length; i++){
if (valueArr[i]){
var splitItem = valueArr[i].split("-");
}
valueArr[i] = {
type: splitItem[0] ? splitItem[0] : '',
name: splitItem[1] ? splitItem[1] : '',
text: splitItem[2] ? splitItem[2] : ''
}
}
var result = valueArr;
ngModel.$setViewValue(result);
}, true);
}
}
})
Although the way you have defined what you want may not be scalable or best practise since it maps 0 to type, 1 to name and 2 to text
