JQuery-based js paging code _ jquery

Jquery's paging code is implemented in combination with the database. Here, only the core jquery code is provided. Other people can make use of it. The Code is as follows:

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 (" Previous Page "). addClass (" pageLink ");
This. prePage. click (function (){
Self. setLink (self. pageIndex-1 );
});
This. nextPage = $ ("" ).html ("next page"). 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 ("No information! ");
}
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,
Type: "get ",
Data: {pageSize: self. pageSize, pageIndex: I },
Cache: false,
Error: function (){
Alert ("data loading failed! ");
},
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. pageCount This. pageIndex = this. pageCount;
}
If (this. pageIndex> 0 ){
This. setLink (this. pageIndex );
}
This. showBarInfo ();
}
}
