如何使错误信息淡入 [英] how to make error message fade in

问题描述

我正在使用此代码进行表单验证

im using this code for form validating

$(document).ready(function(){
// Place ID's of all required fields here.
required = ["name", "email", "country", "message",];
// If using an ID other than #email or #error then replace it here
email = $("#email");
errornotice = $("#error");
// The text to show up within a field when it is incorrect
emptyerror = "Please enter a value in field";
emailerror = "Please enter a valid e-mail.";

$("#theform").submit(function(){    
    //Validate required fields
    for (i=0;i<required.length;i++) {
        var input = $('#'+required[i]);
        if ((input.val() == "") || (input.val() == emptyerror)) {
            input.addClass("needsfilled");
            input.val(emptyerror);
            errornotice.fadeIn(750);
        } else {
            input.removeClass("needsfilled");
        }

    }
    // Validate the e-mail.
    if (!/^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/.test(email.val())) {
        email.addClass("needsfilled");
        email.val(emailerror);
    }

    //if any inputs on the page have the class 'needsfilled' the form will not submit
    if ($(":input").hasClass("needsfilled")) {
        return false;
    } else {
        errornotice.hide();
        return true;
    }
});

// Clears any fields in the form when the user clicks on them
$(":input").focus(function(){       
   if ($(this).hasClass("needsfilled") ) {
        $(this).val("");
        $(this).removeClass("needsfilled");
   }
});
});

问题是如何让空错误和电子邮件错误消失？



i尝试添加此代码但它没有用：emptyerror.hide（）。fadeIn（750）;



我也尝试过括号中的emptyerror，或者像这个$（＃emptyerror）



但是没有一个工作



任何想法？

the question is how can i make the emptyerror and emailerror fade in?

i tried adding this code but it didnt work: emptyerror.hide().fadeIn(750);

I also tried putting the emptyerror in brackets, or like this $("#emptyerror")

but none of them worked

any ideas?

推荐答案

（ document ）。ready（ function （）{
// 此处放置所有必填字段的ID。
required = [ name， email， country ， message，];
// 如果使用#email或#error以外的ID，请在此处替换
email =

(document).ready(function(){ // Place ID's of all required fields here. required = ["name", "email", "country", "message",]; // If using an ID other than #email or #error then replace it here email =

（ #mail）;
errornotice =

("#email"); errornotice =

（ ＃error ）;
// 字段显示错误时显示的字段
emptyerror = 请在字段;中输入值
emailerror = 请输入有效的电子邮件。;

("#error"); // The text to show up within a field when it is incorrect emptyerror = "Please enter a value in field"; emailerror = "Please enter a valid e-mail.";
