Adding HTML elements in the JSON data

Question

Following is my JSON Data validated using JSONLint:

[{
"text": "Products",
"data": {},
"children": [{
    "text": "Fruit",
    "data": {
        "price": "",
        "quantity": "",
        "AddItem": "+",
        "RemoveItem": "&#215"
    },
    "children": [{
        "text": "Apple",
        "data": {
            "price": 0.1,
            "quantity": 20,
            "AddItem": "+",
            "RemoveItem": "&#215"
        }
    }, {
        "text": "Strawberry",
        "data": {
            "price": 0.15,
            "quantity": 32,
            "AddItem": "+",
            "RemoveItem": "& #215"
        }
    }],
    "state": {
        "opened": false
    }
}, {
    "text": "Vegetables",
    "data": {
        "price": "",
        "quantity": "",
        "AddItem": "&# 43;",
        "RemoveItem": "&#215"
    },
    "children": [{
        "text": "Aubergine",
        "data": {
            "price": 0.5,
            "quantity": 8,
            "AddItem": "+",
            "RemoveItem": "&#215"
        }
    }, {
        "text": "Cauliflower",
        "data": {
            "price": 0.45,
            "quantity": 18,
            "AddItem": "+",
            "RemoveItem": "&#215"
        }
    }, {
        "text": "Potato",
        "data": {
            "price": 0.2,
            "quantity": 38,
            "AddItem": "+",
            "RemoveItem": "&#215"
        }
    }]
}],
"state": {
    "opened": false
}
}]

What I am looking for is to convert the value for the keys AddItem and RemoveItem to HTML buttons.

The above JSON will be used to render nodes in a jsTree plugin.

jsFiddle link where I will be using this json data. Basically, I want to replace my + and - sign with a button for the same

Does anyone has a work-around for this ?

Edit 1: I have read at a few places that adding HTML elements directly in your JSON data is not advisable as it can be used at a number of places in your code and each time it may have a different HTML for it. If someone has a better way to do it, that would be great.

Answer 1

I have never used the jsTree plugin and there is probably a better way to solve your problem, but this seems to do what i think your looking for. Just add this to the end of your code.

$(document).on('click','.jstree-table-wrapper', function() {//insted of document i would used jtrees containing div
    $.each($('.jstree-table-cell span'),function(){
        if($(this).html()=='+'){      
            $(this).html('<button class="addBtn">+</button>')
        }else if($(this).html()=='×'){      
            $(this).html('<button class="removeBtn">x</button>')
        }
    });
});

$(document).on('click','.addBtn',function(){//insted of document i would used jtrees containing div
     var id = 'j1_'+$(this).parent().parent().attr('id').split('_')[2];
     demo_create(id);
     $('.jstree-table-wrapper').trigger('click');
});

$(document).on('click','.removeBtn',function(){//insted of document i would used jtrees containing div
     var id = 'j1_'+$(this).parent().parent().attr('id').split('_')[2];
     demo_delete(id);//you might need to work on your delete function
     $('.jstree-table-wrapper').trigger('click');
});
