js分页代码

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"; } else { irow.style.display = "none"; } } var pageEnd = document.getElementById("pageEnd"); var tempStr = "";//"共" + num + "条标准 分" + totalPage + "页 当前第" + currentPage + "页"; if (currentPage > 1) { tempStr += "<a href=\"#\" class=\"btn btn-default\"role=\"button\" onClick=\"goPage(" + (1) + "," + psize + ")\">首页</a>"; tempStr += "<a href=\"#\" class=\"btn btn-default\"role=\"button\" onClick=\"goPage(" + (currentPage - 1) + "," + psize + ")\">上一页</a>" } else { tempStr += "<a href=\"#\" class=\"btn btn-default\"role=\"button\" onClick=\"goPage(" + (1) + "," + psize + ")\">首页</a>"; tempStr += "<a href=\"#\" class=\"btn btn-default\"role=\"button\" onClick=\"goPage(" + (1) + "," + psize + ")\">上一页</a>"; } tempStr += "<a href=\"#\" class=\"btn btn-default active\"role=\"button\">" + currentPage + "/" + totalPage + "</a>"; if (currentPage < totalPage) { tempStr += "<a href=\"#\" class=\"btn btn-default\"role=\"button\" onClick=\"goPage(" + (currentPage + 1) + "," + psize + ")\">下一页</a>"; tempStr += "<a href=\"#\" class=\"btn btn-default\"role=\"button\" onClick=\"goPage(" + (totalPage) + "," + psize + ")\">尾页</a>"; } else { tempStr += "<a href=\"#\" class=\"btn btn-default\"role=\"button\" onClick=\"goPage(" + (totalPage) + "," + psize + ")\">下一页</a>"; tempStr += "<a href=\"#\" class=\"btn btn-default\"role=\"button\" onClick=\"goPage(" + (totalPage) + "," + psize + ")\">尾页</a>"; } document.getElementById("barcon").innerHTML = tempStr; }
