submit的替代

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()

5.button 直接跳转

 onclick="javascript:window.location.href='aa.htm'"

onclick="location='URL'" 
onclick="window.location.href='?id=11'"
