jquery Pop-up box code encapsulation dialoghelper_jquery

Look at the example of jQueryUI dialog, the effect is good, is to use up a bit awkward, write code a bit twisted bar, need to be packaged again! So there is the following simple Dialoghelper helper class, because this article shares the focus is the idea, so the current version of the code is also very rough. The idea is, the follow-up package into what is just a form, hope that this idea can give you some enlightenment, while welcome to open up thinking, and put forward better ideas for improvement.

Copy Code code as follows:

Require Scrollhelper.js
function Dialoghelper () {
var _this = this;
var doc = window.document;
_this.maskdiv = null;
_this.contentdiv = null;
var options = {
opacity:0.4
};
This.popup = function (Contentdiv, optionarg) {
if (Optionarg) {
For (Var prop in Optionarg) {
Options[prop] = Optionarg[prop];
}
}
_this.contentdiv = Contentdiv | | _this.contentdiv;
_this.maskdiv = $ (' <div> ');
_this.maskdiv.addclass (' Maskdiv ');
_this.maskdiv.css ({
' Filter ': Alpha (opacity=) + (Options.opacity-"0") * 100 + ");",
' Opacity ': options.opacity,
' Display ': ' Block '
});
$ (doc.body). Append (_this.maskdiv);
if (_this.contentdiv) {
$ (doc.body). Append (_this.contentdiv);
_this.contentdiv.show ();
_this.contentdiv.draggable ({
Containment: "Document",
Cursor: ' Move ',
Handle: ". Dialog_head "
});
$ (_this.maskdiv). On ("MouseMove", function () {
$ ("Body"). Preventscroll ();
});
$ (_this.maskdiv). On ("Mouseout", function () {
$ ("Body"). Livescroll ();
});
if ($ (". Cke"). Length = = 0 && $ (". Dialog_body "). Length > 0) {
$(". Dialog_body "). Preventouterscroll ();
}
}
};
This.remove = function () {
if (_this.contentdiv) {
_this.contentdiv.remove ();
}
if (_this.maskdiv) {
_this.maskdiv.remove ();
}
$ ("Body"). Livescroll ();
};
This.formatpercentnumber = function (value, whole) {
if (isNaN (value) && typeof value = = "string") {
if (Value.indexof ("%")!==-1) {
Value = (value.replace ("%", "")/MB) * WHOLE;
else if (value.indexof ("px")!==-1) {
Value = Value.replace ("px", "");
}
}
return Math.ceil (value);
};
this.position = function (dialog, Dialogbody, Minusheight) {
Dialog = Dialog | | $(". Showdialogdiv ");
if (Dialog[0]) {
var clientwidth = document.documentElement.clientWidth;
var clientheight = document.documentElement.clientHeight;
var width = _this.formatpercentnumber (Dialog.data ("position"). Width, clientwidth) | | Dialog.width ();
var height = _this.formatpercentnumber (dialog.data ("position"). Height, clientheight) | | Dialog.height ();
width = width < 300? 300:width;

$ (Dialog). CSS ({

if (Dialogbody[0]) {
