我找到了 2 个解决方案 - 第一个是 jquery 小部件工厂
http://jqueryui.com/widget/
js代码:
$.widget("custom.ratiofix",{
options:{
message:"nothing"
},
_create:function (){
var self=this;
this.setListeners();
},
setListeners:function (){
var self=this;
$(window).on('resize',$.proxy(self.printMsg,self));
},
printMsg:function (){
console.log(this.options.message);
}
});
第二个(没有小部件工厂):
(function ($){
var Ratiofix = {
init: function(options, elem) {
this.options = $.extend({},this.options,options);
this.elem = elem;
this.$elem = $(elem);
this.setListeners();
return this;
},
options: {
message: "No message"
},
printMsg: function(){
console.log(this.options.message);
},
setListeners:function (){
var self=this;
this.$elem.on('click',function (){
console.log(self.options.message);
});
$(window).on('resize',$.proxy(self.printMsg, self));
}
};
$.fn.ratiofix=function (options){
this.init= function(options, elem) {
this.options = $.extend({},this.options,options);
this.elem = elem;
this.$elem = $(elem);
return this;
};
if ( this.length ) {
return this.each(function(){
var ratiofix = Object.create(Ratiofix);
ratiofix.init(options, this);
$.data(this, 'ratiofix', ratiofix);
});
}
};
})(jQuery);
在这两种情况下,插件都是单独工作并有自己的设置。在我的情况下 - 2 个小部件监听窗口调整大小并打印到控制台自己的 options.message
