jQuery的一些函數javascript
$.fn.html
jQuery.fn = jQuery.prototype ={ init: function( selector, context ){//.... //...... };
$.extend()java
//jQuery.extend(object); 爲jQuery類添加類方法; 能夠理解爲添加靜態方法,以後即可以在引入 jQuery 的地方,使用這個方法了。 //例如:添加add方法 $.extend({ add:function(a,b){returna+b;} });
$.fn.extend()jquery
//jQuery.fn.extend(object);對jQuery.prototype進得擴展,就是爲jQuery類添加「成員函數 //例如 $.fn.extend({ funcName:function(){ } });
完整代碼以下:ajax
js包括:jquery-1.8.3.min和jquery.page(以下)json
(function($){ var ms = { init:function(obj,args){ return (function(){ ms.fillHtml(obj,args); ms.bindEvent(obj,args); })(); }, //填充html fillHtml:function(obj,args){ return (function(){ obj.empty(); //上一頁 if(args.current > 1){ obj.append('<a href="javascript:;" class="prevPage">上一頁</a>'); }else{ obj.remove('.prevPage'); obj.append('<span class="disabled">上一頁</span>'); } //中間頁碼 if(args.current != 1 && args.current >= 4 && args.pageCount != 4){ obj.append('<a href="javascript:;" class="tcdNumber">'+1+'</a>'); } if(args.current-2 > 2 && args.current <= args.pageCount && args.pageCount > 5){ obj.append('<span>...</span>'); } var start = args.current -2,end = args.current+2; if((start > 1 && args.current < 4)||args.current == 1){ end++; } if(args.current > args.pageCount-4 && args.current >= args.pageCount){ start--; } for (;start <= end; start++) { if(start <= args.pageCount && start >= 1){ if(start != args.current){ obj.append('<a href="javascript:;" class="tcdNumber">'+ start +'</a>'); }else{ obj.append('<span class="current">'+ start +'</span>'); } } } if(args.current + 2 < args.pageCount - 1 && args.current >= 1 && args.pageCount > 5){ obj.append('<span>...</span>'); } if(args.current != args.pageCount && args.current < args.pageCount -2 && args.pageCount != 4){ obj.append('<a href="javascript:;" class="tcdNumber">'+args.pageCount+'</a>'); } //下一頁 if(args.current < args.pageCount){ obj.append('<a href="javascript:;" class="nextPage">下一頁</a>'); }else{ obj.remove('.nextPage'); obj.append('<span class="disabled">下一頁</span>'); } })(); }, //綁定事件 bindEvent:function(obj,args){ return (function(){ obj.on("click","a.tcdNumber",function(){ var current = parseInt($(this).text()); ms.fillHtml(obj,{"current":current,"pageCount":args.pageCount}); if(typeof(args.backFn)=="function"){ args.backFn(current); } }); //上一頁 obj.on("click","a.prevPage",function(){ var current = parseInt(obj.children("span.current").text()); ms.fillHtml(obj,{"current":current-1,"pageCount":args.pageCount}); if(typeof(args.backFn)=="function"){ args.backFn(current-1); } }); //下一頁 obj.on("click","a.nextPage",function(){ var current = parseInt(obj.children("span.current").text()); ms.fillHtml(obj,{"current":current+1,"pageCount":args.pageCount}); if(typeof(args.backFn)=="function"){ args.backFn(current+1); } }); })(); } } $.fn.createPage = function(options){ var args = $.extend({ pageCount : 10, current : 1, backFn : function(){} },options); ms.init(this,args); } })(jQuery);
