html 前端分页代码怎么写,纯JavaScript实现的前端分页代码 转载2021-06-19 11:07:20

最近我遇到问题，就是控制table表格的行不要太长，这里最简单方便的方法就是用前端分页，控制表格显示的行数，在网上找了一番，终于找到一个比较合适的前端分页代码。示例如下：
html代码：
//全局变量
var numCount//数据总数量
var columnsCounts//数据列数量
var pageCount//每页显示的数量
var pageNum//总页数
var currPageNum //当前页数
//页面标签变量
var blockTable
var preSpan
var firstSpan
var nextSpan
var lastSpan
var pageNumSpan
var currPageSpan
window.οnlοad=function(){
//页面标签变量
blockTable = document.getElementById("blocks")
preSpan = document.getElementById("spanPre")
firstSpan = document.getElementById("spanFirst")
nextSpan = document.getElementById("spanNext")
lastSpan = document.getElementById("spanLast")
pageNumSpan = document.getElementById("spanTotalPage")
currPageSpan = document.getElementById("spanPageNum")
numCount = document.getElementById("blocks").rows.length - 1//取table的行数作为数据总数量(减去标题行1)
alert(numCount)
columnsCounts = blockTable.rows[0].cells.length
pageCount = 5
pageNum = parseInt(numCount/pageCount)
if(0 != numCount%pageCount){
pageNum += 1
}
firstPage()
}
