JQuery plug-in development:
Class level development, develop new global functions
Object level development, develop new methods for Jquery objects
1. Class level development- Define global method
jQuery.foo = function( ) {
alert('This is a test.');
};
Using namespace can avoid function conflicts within the namespace.
jQuery.apollo={
fun1:function( ){
console.log('fun1');
},
fun2:function(){
console.log('fun2');
}
}
2. Object level development - defining jQuery object methods
(function($) {
$.fn.pluginName = function() {
};
})( jQuery);
//The plug-in is called like this:
$('#myDiv').pluginName();
Accepts the options parameter to control the behavior of the plug-in
(function($){
$.fn.fun2=function (option){
var defaultOption={
param1:'param1',
param2:'param2'
}
$.extend(defaultOption,option);
console.log (defaultOption);
}
})(jQuery);
$(function(){
//Called like this
$("body").fun2({
param1:'new Param1'
});
});
Keep private functions private
(function($) {
// plugin definition
$.fn.hilight = function(options) {
debug(this);
// ...
};
// private function for debugging
// The "debug" method cannot be entered from the external closure, so for our implementation it is Private.
function debug($obj) {
if (window.console && window.console.log)
window.console.log('hilight selection count: ' $obj.size());
};
// ...
})(jQuery);
