javascript 简单问题求解!!!
在如下一个简单的html页面,代码如下:
<html>
<body>
<table>
<tr id= "t1 ">
<td> <input type= "text " name= "a1 " value= "a1 "> </td>
<td> <input type= "text " name= "b1 " value= "b1 "> </td>
<td> <input type= "button " name= "submit1 " value= "修改 "> </td>
</tr>
<tr id= "t2 ">
<td> <input type= "text " name= "a2 " value= "a2 "> </td>
<td> <input type= "text " name= "b2 " value= "b2 "> </td>
<td> <input type= "button " name= "submit2 " value= "修改 "> </td>
</tr>
<tr id= "t3 ">
<td> <input type= "text " name= "a3 " value= "a3 "> </td>
<td> <input type= "text " name= "b3 " value= "b3 "> </td>
<td> <input type= "button " name= "submit3 " value= "修改 "> </td>
</tr>
</table>
</body>
</html>
我想当点击修改按钮时, 通过javascript获得当前行文本框中的值,例如:
当点击按钮submit1时, 得到文本框a1,b2中的值;
当点击按钮submit2时, 得到文本框a2,b2中的值等, 依次类推!!!
请各位大虾帮忙解决, 小弟不甚感激!!!!谢谢.......
