$.fn.upload = function (options) {

    options = options || {};

    options.dom = this;

    $.upload(options);

}

$.upload = function (options) {

    var settings = {

        dom: "",

        action: "",

        fileName: "file",

        params: {},

        accept: ".jpg,.png,.jpeg,.png",

        },

        submit: function () {



        }

    }

    settings = $.extend(settings, options);

    var ele = settings.dom;



    var iframeName = "leunpha_iframe_v" + Math.random() * 100;

    var width = ele.outerWidth();

    var height = ele.outerHeight();

    var iframe = $("<iframe name='"+iframeName+"' style='display:none;' id='"+iframeName+"'></iframe>");

    var form = $("<form></form>");

    form.attr({

        target: iframeName,

        action: settings.action,

        method: "post",

        "class": "ajax_form",

        enctype: "multipart/form-data"

    }).css({

            width: width,

            height: height,

            position: "absolute",

            top: (ele.offset().top),

            left: (ele.offset().left)

        });

    var input = $("<input type='file'/>");

    input.attr({

        accept: settings.accept,

        name: settings.fileName

    })

        .css({

            opacity: 0,

            position: "absolute",

            width: width,

            height: height + "px",

            cursor: "pointer"

        });

    input.change(function () {

        if(this.value){

            settings.submit.call(form);

            $(this).parent("form").submit();

        }

    });

    form.append(input);

    $("body").append(iframe);

    iframe.after(form);

    for (var param in settings.params) {

        var div = $("<input type='hidden'/>").attr({name: param, value: settings.params[param]});

        input.after(div)

        div = null;

        delete div;

    }

    iframe.load(function () {

        var im = document.getElementById(iframeName);

        var text = $(im.contentWindow.document.body).text();

        if (text) {

            settings.complete.call(null, text);

        }

    });
