html:
<code class="resize1">resize1</code>
<code class="resize2">resize2</code>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>
<script src="js/plugins.js"></script>
<script src="js/main.js"></script>
<script type="text/javascript">
jQuery(document).ready(function($) {
$('.resize1').ratiofix({message:'resize1'});
$('.resize2').ratiofix({message:'resize2'});
});
</script>
我找到了两个解决方案-第一个是jquery widget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);
}
});
第二种方法(不使用小部件工厂):
(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,插件分别工作并具有自己的设置。在我的情况下 - 2个小部件侦听窗口的调整大小并将它们自己的选项消息打印到控制台。
if (typeof foo == 'undefined')
改为if (typeof foo != 'undefined')
