<select id="select1">
    <option>hello</option>

</select>
<input type="checkbox" id="checkbox1" />
<div class="complete-data"></div>

init plugin on any element of the page. This element can be the one on which you want to operate the result.

$(".complete-data").howcomplete({
    elements: [{
        element: $("#input1"),
        weight: 0.4,
        evaluate: function(data){ //data is {words: 2, value: "x y"}
            var wordCount = data.words.length;
            //divide a weight of 1 as per the data. Contribution to 
            // total weight will be calculated by the plugin
            return (wordCount > 4 ? 4 : wordCount)/4;
        }
    },
    {
        element: $("#input2"),
        weight: 0.4,
        evaluate: function(data){
            return data.words.length;
        }
    },
    {
        element: $("#select1"),
        weight: 0.2, //total weight of all elements should be 1
        evaluate: function(data){
            if(data.value == "hello"){
                return 1
            }
            retrn 0.5;
        }
    }],
    calculateOn: "keyup change paste",
    evaluateOnInit: true,
    togglePoints: [
        {
            between: [0, 0.25],
            classname: "red"
        },
