Usage

In general, LittleCub takes a JSON data document with a matched JSON Schema document and produce an HTML form within the container DOM element that your provide.

You can also provide an additional configs JSON document that contains all control related settings such as control type, size of text field etc.

Depending on your use case, you may only need to provide one of the three JSON documents or any combination of the three.

// Renders an array control with a dynamic list of text controls.
var arrayControl1 = LittleCub(["Sample1","S",""], {
    "type" : "array",
    "items" : {
        "type" : "text",
        "label": "Sample",
        "placeholder" : "Enter some text"
    }
}, {
    "type" : "array",
    "items" : {
        "type" : "string",
        "minLength" : 4
    }
},document.getElementById('array-control-1'));

// Validate the new array control and its children
arrayControl1.validate(true);

jQuery is not required for LittleCub although it comes with support for it.

// Renders the same array control with a dynamic list of text controls using jQuery.
$('#array-control-2').lc(["Sample1","S",""], {
    "type" : "array",
    "items" : {
        "type" : "text",
        "label": "Sample",
        "placeholder" : "Enter some text"
    }
}, {
    "type" : "array",
    "items" : {
        "type" : "string",
        "minLength" : 4
    }
}).validate(true);
