How to have member variables and public methods in a jQuery plugin?
- by user169867
I'm trying to create a jQuery plugin that will create something like an autoCompleteBox but with custom features. How do I store member variables for each matching jQuery element?
For example I'll need to store a timerID for each. I'd also like to store references to some of the DOM elements that make up the control.
I'd like to be able to make a public method that works something like:
$("#myCtrl").autoCompleteEx.addItem("1");
But in the implementation of addItem() how can I access the member variables for that particular object like its timerID or whatever?
Below is what I have so far...
Thanks for any help or suggestions!
(function($)
{
//Attach this new method to jQuery
$.fn.autoCompleteEx = function(options)
{
//Merge Given Options W/ Defaults, But Don't Alter Either
var opts = $.extend({}, $.fn.autoCompleteEx.defaults, options);
//Iterate over the current set of matched elements
return this.each(function()
{
var acx = $(this); //Get JQuery Version Of Element (Should Be Div)
//Give Div Correct Class & Add <ul> w/ input item to it
acx.addClass("autoCompleteEx");
acx.html("<ul><li class=\"input\"><input type=\"text\"/></li></ul>");
//Grab Input As JQ Object
var input = $("input", acx);
//Wireup Div
acx.click(function()
{
input.focus().val( input.val() );
});
//Wireup Input
input.keydown(function(e)
{
var kc = e.keyCode;
if(kc == 13) //Enter
{
}
else if(kc == 27) //Esc
{
}
else
{
//Resize TextArea To Input
var width = 50 + (_txtArea.val().length*10);
_txtArea.css("width", width+"px");
}
});
}); //End Each JQ Element
}; //End autoCompleteEx()
//Private Functions
function junk()
{
};
//Public Functions
$.fn.autoCompleteEx.addItem = function(id,txt)
{
var x = this;
var y = 0;
};
//Default Settings
$.fn.autoCompleteEx.defaults =
{
minChars: 2,
delay: 300,
maxItems: 1
};
//End Of Closure
})(jQuery);
