submit的替代

1、用圖檔代替送出按鈕submit和重置按鈕reset，給圖檔加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、給1的圖檔加上style，用于彌補方法1滑鼠移到圖檔上無反應，未能給客戶好的浏覽體驗

<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、用圖檔代替送出按鈕submit和重置按鈕reset，并加上連結，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、使用圖像域。由于預設圖像域點選時都是送出表單，因而要進行适當的處理：

<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中表單送出和重置事件後必須加()，如submit()和reset()

5.button 直接跳轉
