validate与submit
jQuery Validate 插件为表单提供了强大的验证功能，在使用validate.js进行表单的验证时，需要引入一下3个文件：
<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/lib/jquery.js"></script>
<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js"></script>
<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/dist/localization/messages_zh.js"></script> //中文提示包
而validate需要submit的时候才有验证，如何不使用submit的时候，也可以使用表单的验证：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">

<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js"></script>
<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/dist/localization/messages_zh.js"></script>
<style>
.error {

<p>
<input class="submit" type="submit" value="提交">

</p>
</fieldset>
</form>
</body>
<script>
var vali;
vali=$("#signupForm").validate()
$('.nihao').click(function(){
if (vali.form()) {
} else {
}
})
</script>
</html>
当我们点击非submit的时候，也可以进行验证……
