The code in the jQuery pop-up box encapsulates DialogHelper and jquerydialoghelper.

The code in the jQuery pop-up box encapsulates DialogHelper and jquerydialoghelper.

After reading the jQueryUI Dialog example, the result is pretty good. It's a bit awkward to use. The code written 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.

Copy codeThe 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 (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 ({
