Method _ javascript skills

This article mainly introduces how JS achieves the current page center paging effect, and involves related techniques related to javascript page elements and styles, for more information about how to use JavaScript to center pages on the current page, see the examples in this article. Share it with you for your reference. The specific implementation method is as follows:

function show_page(cur_pc){  var cp=cur_pc;  //curent page count  var tp=this.p;  //total page count  var sp=this.pc;  //show page count  var bp;      //begin page count  var ep;      //end page count  if(sp%2==0) sp=sp+1;   //this process need an odd number  var dp=Math.floor(sp/2); //each side count to show  var dif=tp-sp;  //check weather it have enough page to make mid-show  var f=cp-dp;   //to check weather it has enough page to make mid-show from the begin  var g=tp-(cp+dp); //to check weather it has enough page to make mid-show from the end  if(sp && dif>=0)  {    if(g>0)    {      if(f>0)      {         bp=f;         ep=cp+dp;       }      else      {         bp=1;         ep=2*dp+1;       }    }    else    {       bp=tp-2*dp;       ep=tp;     }    }  else  {     bp=1;     ep=tp;   }  var buf=[];  for(var i=bp;i<=ep;i++)  {    if(i==cur_pc)    {      buf.push("",i,"");    }    else    {      buf.push("",i,"");    }  }  document.write(buf);}
