js代码一：
jQuery.fn.extend({
check: function(){
return this.each(function(){this.checked = true;}); //return a jquery object
},
uncheck: function(){
return this.each(function(){this.checked = false;});
}
});
此段js插件开发为对象级别插件开发，即给jquery对象方法。
hml中调用的时候，先引入js，然后点击事件触发方法即可。
$('input:checkbox').check();
$('input:checkbox').uncheck();
js代码二：
(function($){
var methods = {
init: function(options){
return this.each(function(){
var settings = $.extend({}, options);
var $this = $(this);
$this.click(function() {
var ckId = $this.attr('id');
if (ckId == 'checkall') {
if ($this.attr('checked')) {
$this.siblings('input:checkbox').attr('checked', true);
} else {
$this.siblings('input:checkbox').attr('checked', false);
}
}
});
});
}
};
$.fn.tukiCheck = function(){
var method = arguments[];
if (methods[method]) {
method = methods[method];
arguments = Array.prototype.slice.call(arguments, );
} else if (typeof(method) == 'object' || !method) {
method = methods.init;
} else {
$.error( 'Method ' + method + ' does not exist on jQuery.pluginName' );
return this;
}
return method.apply(this, arguments);
};
})(jQuery);
此插件开发为对象级别插件开发。也可以
(function($){
$.fn.extend({
})
})(jQuery)
html中调用：$('input:checkbox').tukiCheck();
js代码三：
//tuki jquery ext
(function($, undefined){
var methods = {
checkall : function(){
var $chekcAllObj = $('#checkall'); if (undefined != $chekcAllObj) {
$chekcAllObj.click(function() {
var $this = $(this);
if ($this.attr('checked')) {
$this.siblings('input:checkbox').attr('checked', true);
} else {
$this.siblings('input:checkbox').attr('checked', false);
}
});
}
//return true;
}
}; $.tukiCheck = function(method) {
// Method calling logic
if (methods[method]) {
return methods[ method ].apply(this, Array.prototype.slice.call(arguments, ));
} else if (typeof method === 'object' || ! method) {
return methods.init.apply(this, arguments);
} else {
$.error('Method ' + method + ' does not exist on jQuery.tukibox');
}
};
})(jQuery);
此插件开发为类级别开发，即直接为jquery类本身添加方法。
html中调用：$.tukiCheck('checkall');
