When there is only one submit button, it can be simply implemented without adding an event function. The code is:
<input type="image" name="..." src="url" width="" height="..." border="...">
Except for the tag being changed to input type="image", other attributes are the same as those of the <img> tag.
2. Use pictures to replace all form buttons:
The image code format instead of the submit button is
<input type="image" name="..." src="..." onClick="()">
The code picture format of the reset button is
<input type="image" name="..." src="..." onClick="()">
Note: The formName here is the name attribute value of the form.
3. Form submission verification:
<script>
function CheckDate(){
//Acquiring the input data
userName = ;
userEmail = ;
//If you do not enter a name
if (userName=="") {
alert("Please enter your name");
();
return false;
}else{
//If the email is not entered, or the email address is incorrect (excluding @)
if ((userEmail=="")||(("@")==-1)) {alert("Please re-enter the email address");
();
return false;
}else return true;
}
}
</script>
4. Submit the form with any element:
Submit the form through onClick="();"; use onClick="();" to reset the form, so that any element can submit the form.
