[Jquery] 获取地址栏参数的方法 备忘

<script type="text/javascript">
(function ($) {
    $.getUrlParam = function (name) {
        var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
        var r = window.location.search.substr(1).match(reg);
        if (r != null) return unescape(r[2]); return null;
    }
})(jQuery);
$(function () {
    alert(window.location.href);
    alert($.getUrlParam('page'));
})
</script>
