基于jQuery的js分页代码_jquery

复制代码如下代码：

function pagerBar(dataCount,pageSize,serverUrl,contentPlace,pagerbarPlace,callBack) {
this.dataCount = dataCount;
this.pageSize = pageSize;
this.serverUrl = serverUrl;
this.contentPlace = $("#" contentPlace);
this.pagerbarPlace = $("#" pagerbarPlace);
this.callBack = callBack;

this.pageCount = 0;
this.pageIndex = 1;
this.curInfo = $("");
this.prePage = $("");
this.nextPage = $("");
this.init();
}
pagerBar.prototype = {
init : function(){
this.getPageCount();
this.initLink();
this.showBarInfo();
if(this.pageCount>0){
this.setLink(1);
}
},
getPageCount : function(){
this.pageCount = parseInt(this.dataCount / this.pageSize);
if(this.dataCount % this.pageSize !=0){
this.pageCount ;
}
},
initLink : function(){
var self = this;
this.prePage = $("").html("上一页").addClass("pageLink");
this.prePage.click(function(){
self.setLink(self.pageIndex-1);
});
this.nextPage = $("").html("下一页").addClass("pageLink");
this.nextPage.click(function(){
self.setLink(self.pageIndex 1);
});
this.pagerbarPlace.append(this.curInfo).append(this.prePage).append(this.nextPage);
},
showBarInfo : function(){
this.prePage.hide();
this.nextPage.hide();

if(this.pageCount==0){
this.curInfo.html("暂时没有信息！");
}
else if(this.pageCount==1){
this.curInfo.html("1/1");
}
else{
this.curInfo.html(this.pageCount "/" this.pageIndex);
}

},
setLink : function(i){
var self = this;
$.ajax({
url:self.serverUrl,
类型:"get",
数据:{pageSize:self.pageSize,pageIndex:i},
缓存:false,
error:function(){
alert("数据加载失败！"
},
success:function(htmlData){
self.contentPlace.html(htmlData); 🎜>if(self.pageCount==1){
self.prePage.hide();
self.nextPage.hide()
}else{
if(i==1); {
self.prePage.hide();
self.nextPage.show();}else if(i==self.pageCount){
self.prePage.show(); 🎜>self.nextPage.hide();
}else{
self.prePage.show();
self.nextPage.show()
}
}
self .pageIndex = i;
self.curInfo.html(self.pageCount "/" self.pageIndex);
if(self.callBack){
self.callBack(); >}
});
},
changeServerUrl : function(dataCount,serverUrl){
this.dataCount = dataCount;
this.serverUrl = serverUrl;
this.pageIndex=1;

this.getPageCount();
this.showBarInfo();
this.contentPlace.html("");
if(this.pageCount>0){
this.setLink(1);
}
},
dataCountDec : function(){
this.dataCount--;
this.getPageCount();
if(this.pageCountthis.pageIndex = this.pageCount;
}
if(this.pageIndex>0){
this.setLink(this.pageIndex);
}
this.showBarInfo();
}
}
