如果要给table里面的td添加颜色，有两种方法：
1 <html> 2 <head> 3 <meta http-equiv="Content-Type" content="text/html;charset=UTF-8"/> 4 <!-- 第一种是用stylecss--> 5 <style type="text/css"> 6 tr:nth-child(even){ /*even：偶数 odd：基数*/ 7 background-color: red; 8 } 9 </style> 10 </head> 11 <body> 12 13 </body> 14 <!-- 第二种是用js+css--> 15 <script> 16 function changeColor(){ //改变颜色的函数 17 var trs = document.getElementsByTagName("tr"); //找到table中的所有的tr 18 for(var i=0;i<trs.length;i++){ 19 if( i%2 == 0){ 20 trs[i].style.background="#cad9ea"; 21 } 22 } 23 } 24 window.onload = changeColor; 25 26 </script> 27 </html>
1 <?php 2 $sql = "select * from movie limit 0,5"; //0:从第一条显示 5：显示5条 3 4 $totalPage = $count % $pageSize == 0 ? intval($count / $pageSize) : intval($count / $pageSize) + 1; 5 //intval是强制换成整型 6 //intval($count / $pageSize) =(int)($count / $pageSize) 7 echo $totalPage; 8 ?>
