代码如下：
<script> function submitonce(theform){ if (document.all||document.getElementById){ for (i=0;i<theform.length;i++){ var tempobj=theform.elements[i] if(tempobj.type.toLowerCase()=="submit"||tempobj.type.toLowerCase()=="reset") tempobj.disabled=true } } } </script> <!--注意在FORM属性中加入 onsubmit="submitonce(this);return false" --> <FORM name=form2 onsubmit="submitonce(this);return false" action="" method=post> <INPUT name=textfield> <INPUT type=submit value=提交 name=Submit> <INPUT type=reset value=重设 name=Submit2> </FORM>
