我正在创建一个jquery ligthbox只是为了学习，现在所有的工作都很大，但是，当我尝试调用插件超过两次时，那么，追加内容会重复自己。
在这里搜索，我找到了这段代码：
var appened = true;
if(appened){
//append code
appened = false;
}
但这不适合我。我要做什么，以避免这种重复的内容？
以防这是我的代码：
(function($){
$.fn.shareBox = function(options){
var defaults = {
fadeSpeed : 500,
hiddenElement: false,
nameHideCont : ''//nombre del contenedor con clase hide
},
settings = $.extend(defaults, options);
var appened = true;
if(appened){
var lb = '<div class="lb-cont"></div><div class="sb-cont"></div>';
$(lb).prependTo('body');
appened = false;
}
var shareB = $('.sb-cont');
shareB.css('display','none');
this.each(function(){
var obj = $(this);
var verMas = $('a', obj)
var lbw = shareB.width();
obj.bind('click', function(){
if(defaults.hiddenElement){
var contenido = $('.'+defaults.nameHideCont, obj).clone(true, true).removeClass('hide');
contenido.appendTo(shareB);
}
$('.lb-cont').fadeIn(defaults.fadeSpeed);
shareB.fadeIn(defaults.fadeSpeed);
shareB = $('.sb-cont');
pos_obj();
var cerrar = '<div id="cerrar-cont"><div id="cerrar">X</div></div>';
$(cerrar).prependTo('.'+defaults.nameHideCont);
$('.imagess').epicZoom({});

})(jQuery);
我用这种方式调用我的插件：
jQuery('.catalogo').shareBox({
nameHideCont:'light-cont',
hiddenElement:true
});
jQuery('.images').shareBox({
nameHideCont:'light-cont2',
});
答案 0 :(得分：0)
只需将prepend部分移出shareBox功能即可。这样，当你的插件注册时，它只会预先填充一次。
