You can use onSubmit to prevent a form from being submitted; to do so, put a return statement that returns false in the event handler. Any other returned value lets the form submit. If you omit the return statement, the form is submitted.
| type | 标明了事件的类型。 |
| target | 标明了事件原来发送的对象。 |
In the following example, onSubmit calls the validate function to evaluate the data being submitted. If the data is valid, the form is submitted; otherwise, the form is not submitted.
<FORM onSubmit="return validate(this)">
...
</FORM>See also the示例 forForm
