Jquery-based checkbox drop-down box plug-in code _ jquery

The first plug-in written by Feng Yi looks like a finger. The jquery-based checkbox drop-down box plug-in option_check.js code is as follows:

The Code is as follows:

/*************************************** **
The call method is as follows:
Jselect ($ ("# inputid "),{
Bindid: 'bindid ',
Hoverclass: 'hoverclass ',
Optionsbind: function () {return hqhtml ();}
});
Inputid is the id of the text box to be bound to the drop-down box.
Bindid is the Control id in the pop-up/pull-back drop-down box.
Hoverclass is the style when you move the cursor over the option.
Hqhtml is the bound data
**************************************** **/
(Function ($ ){
$. Showselect = {
Init: function (o, options ){
Var defaults = {

Optionsbind: function () {}// bind a function to the drop-down list
}
Var options = $. extend (defaults, options );

This. _ setbind (o, options );
