图片代替表单中的提交按钮submit和重置按钮reset

1、用图片代替提交按钮submit和重置按钮reset，给图片加onclick事件 


<script language="javascript"> 
function fsubmit(obj){ 
obj.submit(); 
} 
function freset(obj){ 
obj.reset(); 
} 
</script> 
<form id="form1" name="form1" method="post" action="login.asp"> 
姓名： <input type="text" name="textfield" /> 
<img src="uploads/200707/30_145425_001.jpg" onClick="javascript:fsubmit(document.form1);"> 
<img src="uploads/200707/30_145428_002.jpg" onClick="javascript:freset(document.form1);"> 
</form> 


2、给1的图片加上style，用于弥补方法1鼠标移到图片上无反应，未能给客户好的浏览体验 


<script language="javascript"> 
function fsubmit(obj){ 
obj.submit(); 
} 
function freset(obj){ 
obj.reset(); 
} 
</script> 
<form id="form1" name="form1" method="post" action="login.asp"> 
姓名： <input type="text" name="textfield" /> 
<img src="uploads/200707/30_145425_001.jpg" style="cursor:hand;" onClick="javascript:fsubmit(document.form1);"> 
<img src="uploads/200707/30_145428_002.jpg" style="cursor:hand;" onClick="javascript:freset(document.form1);"> 
</form> 


3、用图片代替提交按钮submit和重置按钮reset，并加上链接，效果同2 


<script language="javascript"> 
function fsubmit(obj){ 
obj.submit(); 
} 
function freset(obj){ 
obj.reset(); 
} 
</script> 
<form id="form1" name="form1" method="post" action="login.asp"> 
姓名： <input type="text" name="textfield" /> 
<a href="javascript:fsubmit(document.form1);"><img src="uploads/200707/30_145425_001.jpg" border="0" /></a> 
<a href="javascript:freset(document.form1);"><img src="uploads/200707/30_145428_002.jpg" border="0" /></a> 
</form> 


4、使用图像域。由于默认图像域点击时都是提交表单，因而要进行适当的处理： 


<script language="javascript"> 
function fsubmit(obj){ 
obj.submit(); 
} 
function freset(obj){ 
obj.reset(); 
} 
</script> 
<form id="form1" name="form1" method="post" action="login.asp"> 
姓名： <input type="text" name="textfield" /> 
<input type="image" name="imageField" onClick="javascript:fsubmit(document.form1);return false;" src="uploads/200707/30_145425_001.jpg"> 
<input type="image" name="imageField2" onClick="javascript:freset(document.form1);return false;" src="uploads/200707/30_145428_002.jpg"> 
</form> 

要注意的是JS中表单提交和重置事件后必须加()，如submit()和reset()
