The code in the jQuery pop-up box encapsulates DialogHelper_jquery.

This article mainly introduces how to encapsulate DialogHelper in the jQuery pop-up box code. If you need it, you can refer to the example of jQueryUI Dialog. The effect is good, but it is a bit awkward to use, the Code is a bit unscrewed and needs to be encapsulated! So we have the following simple DialogHelper helper class, because the focus of this article is the idea, so the current version of the code is still very rough. The train of thought is correct. We hope that this train of thought will give you some inspiration. At the same time, we welcome everyone to think and propose better suggestions for improvement.

The Code is as follows:

// Require ScrollHelper. js
Function DialogHelper (){
Var _ this = this;
Var doc = Invalid invalid doc ument;
_ This. maskDiv = null;
_ This. contentDiv = null;
Var options = {
Opacity: 0.4
};
This. popup = function (contentp, optionArg ){
If (optionArg ){
For (var prop in optionArg ){
Options [prop] = optionArg [prop];
}
}
_ This. contentDiv = contentp | _ this. contentDiv;
_ This. maskDiv = $ ('

');
_ 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 ("%", "")/100) * 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.doc umentElement. clientWidth;
Var clientHeight = document.doc umentElement. 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;
Height = height <450? 450: height;
$(Dialog).css ({
"Width": width + "px ",
"Height": height + "px ",

});
DialogBody = dialogBody | $ (". Dialog_Body ");
If (dialogBody [0]) {
