JavaScript EasyPager 分页函数

复制代码代码如下: var EasyPager = function(wrap,pageCount,currPage){ var d = document ,el = function(tag,inner,click,css){ tag = d.createElement(tag); inner && (tag.innerHTML = inner); click && (tag.onclick = click); css && (tag.className=css); return tag; } ,append = function(parent,children,child){ children = [].concat(children); for(var i=0,j=children.length;i<j;i++){ child = children[i]; child && parent.appendChild(child); } return parent; } ,easyFn = function(n){return function(){EasyPager(wrap,pageCount,n)}} ,box = el("div"),firstPage,prevPage,lastPage,nextPage,startNum,endNum,pages= []; currPage!=1 && (firstPage = el("span","<<",easyFn(1)),prevPage = el("span","<",easyFn(currPage-1))); currPage!=pageCount && (lastPage = el("span",">>",easyFn(pageCount)),nextPage = el("span",">",easyFn(currPage+1))); (pageCount<=10) ? (startNum=1,endNum=pageCount) : (startNum=currPage-4,endNum = currPage+5,(currPage<=5) && (startNum=1,endNum=10),(currPage>=pageCount-5)&&(endNum=pageCount,startNum=pageCount-10+1)); for(var i=startNum;i<=endNum;i++)pages.push(el("span",i,easyFn(i),i==currPage?"currSpan":null)) append((wrap.innerHTML="",wrap),append(box,[firstPage,prevPage].concat(pages).concat(nextPage,lastPage))); };

javascript做带小数的计算时，会出现9的循环，以下方法帮助解决。第一个参数是需要处理的数值，第二个参数是需要保留的小数位数。自家项目里面就这么用了~ 复制代码代码如下: function round(v,e){ var t=1; for>>>详细阅读
