我试图创建一个表单，其中所有的字段都必须填写，然后才能成功提交。因此，例如，我有一些逻辑，如果发生错误，错误计数器递增，并且如果计数器不等于0，则表单不提交并且出现警告框，告诉用户有一些空的字段需要填写。 这就是预期的行为。但是，当我尝试再次提交时，即使出现错误，它也会成功提交。jQuery/PHP表单提交意外行为
如果它可以更容易，这里是有问题的网页的临时网址：http://176.32.230.49/cecc.co.uk/add-season.php
这里是我的代码：
的jQuery（有问题的代码）
$("#season-submit").on('click', function(e) {
e.preventDefault();
var errorFree = 0;
//var competitionEntries = $(".text-box").val();
// if ($("#season-form").find(competitionEntries).val() == "") {
// competitionEntries.val("Illegals");
$(".text-box").each(function() {
if ($(this).val() == "" && !($(this).siblings(".error-box").is(":visible"))) {
var fieldName = $(this).siblings(".error-box").attr("id");
fieldName = fieldName.substr(0, fieldName.indexOf('-'));
fieldName = fieldName.charAt(0).toUpperCase() + fieldName.slice(1);
//console.log($(this).siblings(".error-box").attr("id"));
if (fieldName == "Competition") {
$(this).siblings(".error-box").text("Which " + fieldName + "?").slideDown();
errorFree++;
} else {
$(this).siblings(".error-box").text("Please enter " + fieldName + "...").slideDown();
errorFree++;
}
} else if ($(this).val() != "" && $(this).siblings(".error-box").is(":visible")) {
$(this).siblings(".error-box").slideUp();
}
});
$(".dpt").each(function() {
var dateTimeValue = $(this).val();
if (dateTimeValue.length == 16 && isValid(dateTimeValue)) {
var day = parseFloat(dateTimeValue.substring(0,2));
var month = parseFloat(dateTimeValue.substring(3,5)) - 1;
var year = parseFloat(dateTimeValue.substring(6,10));
var hour = parseFloat(dateTimeValue.substring(11,13));
var minute = parseFloat(dateTimeValue.substring(14,16));
dateTimeValue = new Date(year, month, day, hour, minute);
} else {
errorFree++;
$(this).siblings(".error-box").text("Stop trying to be clever...").slideDown();
}
});
if (errorFree == 0) {
$("#season-form").submit();
} else {
console.log("Ride this way...");
alert("Not all entries are valid. Please correct them.");
}
//span2 dpt
// }
// $("#season-form").find(competitionEntries).val("Illegals");
console.log("Oh, she wasn't");
});
