对于，输入以焦点下一个元素禁用JS验证

Question

请检查下面的JS小提琴：

我创建了一个表格，当我输入时，它选择了下一个输入，最后提交表单。

但是，此功能会禁用我的验证功能，并且在提交表单时，函数Validate（）不起作用。

提交表格时，我是否有任何方法可以发射功能validate()？

有一个简单的示例可以向您展示如何在表单提交之前检查或调用验证函数

e.preventDefault ：用于防止默认功能

$(function() {
$("#entertonext").submit(function(e) {
e.preventDefault();
// validate code (calling function)
validate();
});
});
function validate() {
alert('Validating');
}
