第一种:鼠标经过时table表格中的颜色根据奇偶行改变不同的颜色
1 <!DOCTYPE html> 2 <html> 3 <head> 4 <meta charset="UTF-8"> 5 <title></title> 6 <script type="text/javascript"> 7 function changeOver(elementId){ 8 //声明指定相关表元素 9 var table1 = document.getElementById("table1").children[0]; 10 //for循环语句 11 for(var i=0;i<table1.children.length;i++){ 12 //if判断语句 13 if(table1.children[i]==elementId){ 14 //奇数行 15 if(i%2==1) 16 //当鼠标覆盖到表格奇数行时,相关单元格背景色变为#CCCCCC色 17 elementId.style.background="red"; 18 //偶数行 19 else 20 //当鼠标覆盖到表格偶数数行时,相关单元格背景色变为#F2F2F2色 21 elementId.style.background="green"; 22 } 23 } 24 } 25 //当鼠标离开相关单元格时所触发的事件 26 function changeOut(elementId){ 27 //当鼠标离开相关表格相关行时,其相关行背景色变为#FFFFFF色 28 elementId.style.background="#FFFFFF"; 29 } 30 31 32 </script> 33 <style type="text/css"> 34 /*表格的样式*/ 35 table{ 36 width: 200px; 37 height: 400px; 38 border: 1px solid; 39 } 40 tr td{ 41 width: 100px; 42 height: 50px; 43 border: 1px solid; 44 } 45 </style> 46 </head> 47 <body> 48 <!--onmouseover鼠标经过时触发的函数,onmouseout鼠标离开时触发的函数--> 49 <table id="table1" > 50 <tr onmouseover="changeOver(this)" onmouseout="changeOut(this)"> 51 <td >1</td> 52 </tr> 53 <tr onmouseover="changeOver(this)" onmouseout="changeOut(this)"> 54 <td>2</td> 55 </tr> 56 <tr onmouseover="changeOver(this)" onmouseout="changeOut(this)"> 57 <td>3</td> 58 </tr> 59 <tr onmouseover="changeOver(this)" onmouseout="changeOut(this)"> 60 <td>4</td> 61 </tr> 62 <tr onmouseover="changeOver(this)" onmouseout="changeOut(this)"> 63 <td>5</td> 64 </tr> 65 <tr onmouseover="changeOver(this)" onmouseout="changeOut(this)"> 66 <td>6</td> 67 </tr> 68 <tr onmouseover="changeOver(this)" onmouseout="changeOut(this)"> 69 <td>7</td> 70 </tr> 71 <tr onmouseover="changeOver(this)" onmouseout="changeOut(this)"> 72 <td>8</td> 73 </tr> 74 75 </table> 76 </body> 77 </html>
第二种:直接用css发生改变,使用了伪类选择器nth-child
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <style type="text/css"> /*奇数改变的颜色*/ tr:nth-child(odd){background-color:#FFE4C4;} /*偶数改变的颜色*/ tr:nth-child(even){background-color:#F0F0F0;} /*table样式*/ table{ width: 200px; height: 400px; border: 1px solid; } /*tr.td的样式*/ tr td{ width: 100px; height: 50px; border: 1px solid; } </style> </head> <body> <!--设计的一个简单表格--> <table id="table1" > <tr> <td >1</td> </tr> <tr> <td>2</td> </tr> <tr> <td>3</td> </tr> <tr> <td>4</td> </tr> <tr> <td>5</td> </tr> <tr > <td>6</td> </tr> <tr > <td>7</td> </tr> <tr> <td>8</td> </tr> </table> </body> </html>
