Let’s continue the previous document to look at page.js code,

var Page = {
url:'',//URL address
method:'GET',
display:'',//Page display method Default || Default2 || You can also customize it Definition
Plugins:'', //Return JSON data, you need to use this function to format the custom function
pagediv:'', //DIV displayed with pagination characters
index:'[First page ]',
lastpage:'[previous page]',
nextpage:'[next page]',
endpage:'[last page]',
lastten:'[last 10 pages]',
nextten:'[Next 10 pages]',
javascript:'Page.Open',//It's very depressing~Function name
Send: function(method,url,pars, fun) {// Ajax connection initialization
new Ajax.Request( url,{method: method, parameters: pars, onComplete: eval('this.Result')});
},
Open: function(pageno){
SetCookie('pageno',pageno);
pars='pageno='+pageno;
url=this.url;
fun=this.display;
method=this.method;
Page.Send(method,url,pars,fun);
},
Init:function(url,options){
this.url=url;
this.display=options.display;
this.pagediv=options.pagediv;
this.Plugins=options.format;
pageno=GetCookie('pageno')?GetCookie('pageno'): 1;
this.Open(pageno);
},
Result:function(http) {
if(http.readyState == 4 ) {
if(http.status == 200) {
var response=http.responseText;
response=eval("("+response+")");
if(response.result) eval(Page.Plugins)(response.result) ;
pageno=parseInt(response.page.pageno);
totalpage=parseInt(response.page.totalpage);
number=parseInt(response.page.number);
try{
eval('Page.'+Page.display)(pageno,totalpage,number);//Calling the paging control function, there are actually three parameters to customize more paging styles
}
catch(e ){
try{
eval(Page.display)(pageno,totalpage,number);
}
catch(e){
alert('Undefined paging control handler' +Page.display);
}
}
}
}
},
number:function(pageno,totalpage,number) {
pagenums=10;
page=Math.ceil(pageno/pagenums);
pagenum=Math.ceil(totalpage/pagenums);
if(page==pagenum) nums=(totalpage-(pagenum-1)*pagenums); else nums=pagenums;
htmlstr='';
if(number==0) htmlstr+='There is no record on the current page! ';
else{
if(page==1) htmlstr+=Page.lastten;
else
htmlstr+=''+Page.lastten+'';
if(pageno==1) htmlstr+=Page.lastpage;
else
htmlstr+=''+Page.lastpage+'';
for( p=1;p<=nums;p++) {
htmlstr+='';
If(pageno==((page-1)*pagenums+p))
p)+']';
        else
    htmlstr+='['+((page-1)*pagenums+p)+']< ;/span>';
}
if(pageno==totalpage)
htmlstr+=Page.nextpage;
else
htmlstr+=''+Page.nextpage+'';
if(page==pagenum)
htmlstr+= Page.nextten;
else
       htmlstr+=''+Page.nextten+'';
       htmlstr+='[共'+totalpage+'页|'+number+'条记录]';
  }
     $(Ajaxdiv).innerHTML=htmlstr;
 },
 string:function(pageno,totalpage,number) {
  htmlstr='';
   if(number==0) htmlstr+='当前页没有任何记录！';
      else{
      if(pageno==1) htmlstr+=' '+Page.index+' '+Page.lastpage;
         else{
       htmlstr+=' '+Page.index+' '+Page.lastpage+'';
    }
      if(pageno==totalpage) htmlstr+=' '+Page.nextpage+' '+Page.endpage+' ';
       else{
       htmlstr+=' '+Page.nextpage+' '+Page.endpage+' ';
    }
    htmlstr+='[共'+totalpage+'页|'+number+'条记录]';
  }
     $(Page.pagediv).innerHTML=htmlstr;
 }
}//结束

 

这个文件主要的作用就是实现在客气有分页效果喽.
