js分页“编程开发”

  function goPage(pno, psize) {
        var itable = document.getElementById("houseList").getElementsByTagName("li");
        var num = itable.length; // li 的数量
        var totalPage = 0;//总页数
        var pageSize = psize;//每页显示li数
        //总共分几页
        if (num / pageSize > parseInt(num / pageSize)) {
            totalPage = parseInt(num / pageSize) + 1;
        } else {
            totalPage = parseInt(num / pageSize);
        }
        var currentPage = pno;//当前页数
        var startRow = (currentPage - 1) * pageSize + 1;//开始显示的行
        var endRow = currentPage * pageSize;//结束显示的行
        endRow = (endRow > num) ? num : endRow; 40
        //遍历显示数据实现分页
        for (var i = 1; i < (num + 1) ; i++) {
            var irow = itable[i - 1];
            if (i >= startRow && i <= endRow) {
                irow.style.display = "block";
