一个比较轻巧好用的js分页插件，可ajax可url

var pageNav = pageNav || {};
pageNav.fn = null;
pageNav.pre = "pre";
pageNav.next = "next";
pageNav.nav = function (a, b) {
if (1 >= b)return this.pn = this.p = 1, this.pHtml2(1);
b < a && (a = b);
var c = "";
1 >= a ? a = 1 : (c += this.pHtml(a - 1, b, pageNav.pre), c += this.pHtml(1, b, "1"));
this.p = a;
this.pn = b;
var d = 2, e = 9 > b ? b : 9;
7 <= a && (c += "...", d = a - 4, e = a + 4, e = b < e ? b : e);
for (; d < a; d++)c += this.pHtml(d, b);
c += this.pHtml2(a);
for (d = a + 1; d <= e; d++)c += this.pHtml(d, b);
e < b && (c = c + "..." + this.pHtml(b, b));
a < b && (c += this.pHtml(a + 1, b, pageNav.next));
return c
};
pageNav.pHtml = function (a, b, c) {
return" <a href='javascript:pageNav.go(" + a + "," + b + ");' class='pageNum'>" + (c || a) + "</a> "
};
pageNav.pHtml2 = function (a) {
return" <span class='cPageNum'>" + a + "</span> "
};
pageNav.go = function (a, b) {
document.getElementById("pageNav").innerHTML = this.nav(a, b);
null != this.fn && this.fn(this.p, this.pn)
};
/*
