我有一些问题阻止表单提交下面的代码。 表单具有动态输入。没有开始，但他们后来添加，但用户。 此代码不显示所有动态字段代码，但数组中会有5或6个字段，如类型[]。jquery防止表单提交
我想要做的是防止表单提交，直到至少有一组动态输入已被添加和验证。该代码还没有验证。
我试过下面的代码示例，但它似乎没有工作，当我点击提交时没有动态字段，它仍然重置所有输入。
submitHandler: function(form) {
form.submit(function(event) {
event.preventDefault();
});
}
submitHandler: function(form) {
form.submit(function() {
return false();
});
}
如果没有动态字段，我想显示一个错误，告诉他们在表单可以提交之前至少完成1个。
在JQuery中，x是已经创建的字段的数量，所以这就是我所想的可以用来防止表单提交。
预先感谢您。
