Cut the crap and code first


jQuery.fn.dataset = function(attr, val) {
    //  Get data set 
    if (arguments.length == 0) {
      var dataset = {};
      jQuery(this).eq(0).each(function() {
        var attrs = this.attributes;
        for (var i = 0, l = attrs.length; i < l; i++) {
          var attr = attrs[i];
          if (/^data-/i.test(attr.name)) {
            dataset[decode(encode(attr.name.substring(5)))] = autobox(attr.value);
            if (decode(encode(attr.name.substring(5))) == "path") {
              dataset[decode(encode(attr.name.substring(5)))] = attr.value != null ? String(attr.value) : null;
            }
            if (decode(encode(attr.name.substring(5))) == "name") {
              dataset[decode(encode(attr.name.substring(5)))] = attr.value != null ? String(attr.value) : null;
            }
          }
        }
      });
      return dataset;
    }

    //  Returns specified data 
    if (arguments.length == 1 && typeof attr != 'object') {
      if(encode(attr) == "data-path"){
        return this.attr(encode(attr));
      }
      return autobox(this.attr(encode(attr)));
    }

    //  Set data set 
    var dataset = attr;
    if (typeof attr != 'object') {
      dataset = {};
      dataset[attr] = String(val);
    }
    var tmp = {};
    jQuery.each(dataset, function(k, v) {
      tmp[encode(k)] = autobox(v);
    });
    return this.attr(tmp);
  };

Using jQuery to make components, we can easily get custom properties of data- and assign values to data- properties.

Access to:


$("div").dataset("name") // To obtain data-name The value of the 

Assignment:


$("div").dataset("name","Tezml") // to data-name This property is assigned a value of Tezml
