我正在进行表单验证。一切都工作正常,我真正想要的是我想添加一些更多的输入字段,如复选框,单选按钮,选择和textarea,上传文件等,所以我希望它们也被验证。
我收到了电子邮件输入错误,但它无法正常工作,因为它应首先验证电子邮件然后它应该删除错误消息,但它只是在输入几个字符后删除错误消息。
我希望验证电话号码。就像用户应该在印度输入10位数字一样,如果在另一个国家/地区会有所不同,我会对如何做到这一点感到困惑。
我希望在正确验证所有字段时弹出成功消息。我试过的是这个:
$('.success_msg').fadeIn().delay(3000).fadeOut();
$('input , textarea , select').val('').removeClass('valid');
event.preventDefault();
我希望在完成所有验证并发送成功消息后清除所有字段。
有人能指出我正确的方向吗?

我已将选择器更改为使用ID
您需要在句柄错误中使用循环:
var Validator = function(form) {
this.form = $(form);
var Elements = {
name: {
selector: $('input[type=text]'),
reg: /^[a-zA-Z]{2,20}$/
},
email: {
selector: $('input[type=email]'),
reg: /^[a-z-0-9_+.-]+\@([a-z0-9-]+\.)+[a-z0-9]{2,7}$/i
},
message: {
selector: $('textarea'),
reg: /^\s+$/
}
};
var handleError = function(element, message, v1) {
if (v1.selector.length > 1) {
var ss = v1.selector;
$(ss).each(function(i, v) {
$(v).removeClass('input-error');
if($(v).val() == ''){
$(v).addClass('input-error');
var $err_msg = $(v).parent('div');
if($(v).parent('div').find('.error').length == 0) {
var error = $('<div class="error"></div>').text(message);
}else{
$(v).parent('div').find('.error').text('');
var error = $(v).parent('div').find('.error').text(message);
$(this).siblings('.error').show();
}
error.appendTo($err_msg);
}else{
$(v).siblings('.error').text('')
}
$(v).keyup(function() {
$(error).fadeOut(1000, function() {
element.removeClass('input-error');
});
});
});
} else {
element.addClass('input-error');
var $err_msg = element.parent('div');
if(element.parent('div').find('.error').length == 0) {
var error = $('<div class="error"></div>').text(message);
}else{
element.parent('div').find('.error').text('');
var error = element.parent('div').find('.error').text(message);
$(this).siblings('.error').show();
}
error.appendTo($err_msg);
element.keyup(function() {
$(error).fadeOut(1000, function() {
element.removeClass('input-error');
});
});
}
};
this.validate = function() {
this.form.submit(function(e) {
for (var i in Elements) {
var type = i;
var validation = Elements[i];
switch (type) {
case 'name':
if (!validation.reg.test(validation.selector.val())) {

我希望这是你想要实现的目标。这花费的时间比预期的要长,但我试图实现它。整个表格是自定义表格。您可以使用现有的插件来实现它。任何方式需要花费很多时间来弄明白。考虑一下这个问题,因为大多数事情都在起作用,如果某些事情不符合您的要求,请忽略它。
