function dolistpage(pagerow,pagenum,rowcount,pagecount){ $("#pagemsg").html("每页显示"+pagerow+"条，当前" + pagenum + "/" +pagecount + "页 共" +rowcount + "条"); if (pagenum == 1) {  $("#fpbtn").attr("disabled", true);  $("#rpbtn").attr("disabled", true); }else {  $("#fpbtn").removeAttr("disabled");  $("#rpbtn").removeAttr("disabled"); } if (pagenum == pagecount) {  $("#npbtn").attr("disabled", true);  $("#lpbtn").attr("disabled", true); }else {  $("#npbtn").removeAttr("disabled");  $("#lpbtn").removeAttr("disabled"); } $("#fpbtn").click(function(){  loadtpage(1); }); $("#rpbtn").click(function(){  loadtpage(pagenum - 1); }); $("#npbtn").click(function(){  if ((pagenum + 1) >= pagecount)    loadtpage(pagecount);  else   loadtpage(pagenum + 1); }); $("#lpbtn").click(function(){  loadtpage(pagecount); }); $("#gpbtn").click(function(){  var tzys = $("#gpinput").val();  var re = /^[1-9]+[0-9]*$/;  if (tzys == null || tzys == undefined || tzys == '') {   alert("请输入跳转页数!");   $("#gpinput").focus();   return;  }  if (!re.test(tzys)) {   alert("请输入正确跳转页数!");   $("#gpinput").focus();   return;  }  if (tzys > pagecount)    tzys = pagecount;  if (tzys <= 0)    tzys = 1;  loadtpage(tzys); }); $("#gpinput").val(pagenum);}
