当您使用dropzone.processqueue()提交表单时,dropzone不知道需要输入,我认为最简单的方法是在处理队列之前,使用javascript手动验证提交按钮的同一事件侦听器中的输入值
例如:
init: function() {
dzClosure = this; // Makes sure that 'this' is understood inside the functions below.
document.getElementById("submit-all").addEventListener("click", function(e) {
e.preventDefault();
e.stopPropagation();
var validFirstName = document.getElementById("firstname").checkValidity();
var validLastName = document.getElementById("lastname").checkValidity();
if (!validFirstName || !validLastName) {
// Here you can handle the empty input case, color the inputs red or whatever
return false;
} else {
dzClosure.processQueue();
}
});
}
