1. Use images instead of submit buttons
When there is only one submit button, it can be easily implemented without adding an event function. The code is:
<input type = "image"' name = "..." src = "url" width= “” height = “” border = “”>
Except that the label is changed to input type = "image", other attributes are the same as those of the tag.
2. Use pictures to replace all form buttons
The picture format that replaces the submit button is
<input type = "image" name = "..." src = "..."inclick ="document.foormName.submit()">
The code picture format that replaces the reset button is:
<input type = "image" name ="..." src = "..." onclick = "document.formName.reset()">
Note: fromName here is the name attribute of the form
3. Form submission verification:
<script> function checkdate(){ //取得输入数据 userName = document.RedForm.userName.value userEmail = document.RedForm.userEmail.value //如果没有输入名字 if(userName== ""){alert("请输入名字"); document.RedForm.userName.focus(); return false; }else{ //如果没有输入Email,或者Email地址错误(不含@) if(userEmail == "")||(userEmail.indexOf("@")== 1)){alret("请输入Email地址"); document.RedForm.userEmail.focus(); return false; }else return true; } } </script>
4. Submit the form with any element
through onclick = “document. from.submit()" to submit the form, and use onclick = "document.from.reset()" to reset the form, this way. Any element can submit the form.
