Pagination with arrows in javascript -


here javascript code:

function setpage(currentpage){     currentpage = parseint(currentpage) + 1;     var last = json.parse(localstorage.getitem("attempt"));     var lastpage = last.length - 1;     var prevcurpage = currentpage - 1;     var prevcurpage2 = currentpage - 2;     var nextcurpage = currentpage + 1;     var nextcurpage2 = currentpage + 2;     var content = "";     if(lastpage == 1){      }else{     if(currentpage == 1){         if(lastpage > 2){             content+=" [<a href=''>"+currentpage+"</a>] | ";             content+=" <a href=''>"+nextcurpage+"</a> | ";             content+=" <a href=''>"+nextcurpage2+"</a> | ";         }else{             content+=" [<a href=''>"+currentpage+"</a>] | ";             content+=" <a href=''>"+nextcurpage+"</a> | ";         }      }else if(currentpage == lastpage){         if(lastpage > 2){             content+=" <a href=''>"+prevcurpage2+"</a> | ";             content+=" <a href=''>"+prevcurpage+"</a> | ";             content+=" [<a href=''>"+currentpage+"</a>] | ";         }else{             content+=" <a href=''>"+prevcurpage+"</a> | ";             content+=" [<a href=''>"+currentpage+"</a>] | ";         }     }else{             content+=" <a href=''>"+prevcurpage+"</a> | ";             content+=" [<a href=''>"+currentpage+"</a>] | ";             content+=" <a href=''>"+nextcurpage+"</a> | ";     } }

the currentpage started in 0; need add 1; why not displaying correct pagination? , how put arrows?

i want show,

currentpage = 0; [1] | 2 | 3 > currentpage = 2; 1 | 2 | [3] | 4 | 5 > currentpage = 7; < 4 | 5 | [6]

try this:

if (currentpage > 3)     content += " < "; content += currentpage - 2 > 0 ? "<a href=''>"+(currentpage - 2)+"</a> | " : ''; content += currentpage - 1 > 0 ? "<a href=''>"+(currentpage - 1)+"</a> | " : '';  content += "[" + currentpage + "]";  content += currentpage + 1 <= lastpage ? " | <a href=''>"+(currentpage + 1)+"</a>" : ''; content += currentpage + 2 <= lastpage ? " | <a href=''>"+(currentpage + 2)+"</a>" : ''; if (currentpage < lastpage - 2)     content += " > ";

or better flexibility, use sort of range variable:

var range = 2;  if (currentpage > range + 1)     content += " < ";  (var = range; > 0; a--)     content += currentpage - > 0 ? "<a href=''>"+(currentpage - a)+"</a> | " : '';  content += "[" + currentpage + "]";  (var = 1; <= range; a++)     content += currentpage + <= lastpage ? " | <a href=''>"+(currentpage + a)+"</a>" : '';  if (currentpage < lastpage - range)     content += " > ";
