My first post here #stackoverflow. Please bear with me.
Look at the code below. I want the javascript to post to an PHP (applybeta.php) document IF there is a '#' in the field with the name & id 'epost'. If there isn't a '#' in the field, a messagebox will pop up telling the user they entered an invalid e-mail address.
If you don't enter a '#' the message box shows up. But if you do enter a valid email it doesn't post to "applybeta.php", nothing happens at all. Anybody got an idea why? Sorry if the description is vague, hopefully you'll figure out what I mean :)
The e-post field got both an id and a name because I tried with both, none of them works.

Instead of having an input of type button, try submit. Your onclick-function can then serve as a validation function by returning true or false, and thus influence whether the form will be submitted. Something like this:
<input onclick="return kollaepost()" type="submit" name="submit" value="Send" />
and:
<script>
function kollaepost() {
var x = document.getElementById("email");
if(x.value.indexOf('#') === -1) {
alert("You didn't enter a valid E-mail address!");
return false;
}
return true;
}
</script>
Also see this question for a more detailed explanation on this method, in general.
You can submit your form using the .submit() method.
var fromElement = document.getElementById("minForm");
formElement.submit();

I have been trying to solve the problem that I am having with this email validation in JavaScript, but all the code I have tried was having the same problem. When I used the developer tool in google chrome I didn't see any error message, so I don't understand why is this happening. I want to show the error message if an email is not valid.
What am I missing?
link full code - https://jsfiddle.net/lmanhaes/cq1g5dyt/14/
Thanks.
function checkEmail(validate) {
let re = /^(([^<>()[\]\\.,;:\s#\"]+(\.[^<>()[\]\\.,;:\s#\"]+)*)|(\".+\"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
let email = validate.userName.value;
if (email === re)
return true;
else {
error.setAttribute("class", "error");
error.innerHTML = ("Email is not correct. Please retype.");
}
}

You should use test() method of regex to return true or false if input value matches the email pattern.
if (re.test(email)){
//logic when it is valid
}
else{
//logic when it is invalid
}
const email = document.getElementById('email');
function validate(){
const regex=/^(([^<>()[\]\\.,;:\s#\"]+(\.[^<>()[\]\\.,;:\s#\"]+)*)|(\".+\"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/
return regex.test(email.value) ?console.log("Valid"):console.log("Invalid");
}
<input type="email" id="email" />
<button onclick="validate()">

</button>
I am trying to create a prompt dialog box using alertifyjs that has multiple input boxes. I have managed to create the dialog box to show the multiple boxes but I cant seem to make a reference to the inputs that user provides.
I want to write if statement that carries out action based on user input when they press OK. However, the OK button doesnt seem to be working and also the if-statements don't work as well. I am not sure what I might be doing wrong, can someone please help me.

Link to JSfiddle: http://jsfiddle.net/1qouxdkc/4/
In your script you call a function named updateListItems(inpOneVal,inpTwoVal);
As that function is not declared anywhere, it errors, so with that temporarily commented out, it works.

i'm testing a HTML using a to check what a servlet returned,
to choose which message i'll show. The app runs ok, the servlet returns correctly. The get what the servlet returned and chooses the message. But, the tag shows the message only for a second (like a flash) and erase shortly thereafter. Below you can see my code:
<!DOCTYPE html>
<html lang ="pt-br">

function oMsg()
{
var wMsg1 = document.getElementById('wMsg').innerHTML;
if (wMsg1 == "Test OK!")
{
document.getElementById('wMsga').innerHTML="Test is OK";
}
else
{
document.getElementById('wMsga').innerHTML="Test is not OK";
}
}

Could you help me, please? Thanks.
I'm not sure if I'm answering what you are looking for, but adding return false to onclick will keep you on the same page:
<input type="submit" value="Submit" name="B1" onclick="oMsg(); return false;">
As the title suggests I'm trying to show the results of a query and it works properly, but it shows the results automatically beneath the search button, when it should wait for the button to be pressed and then reload the page and show the results. I'm kind of sure that it's a problem with the code but I cannot find where. I know it's a stupid question but all help is appreciated.
Here is my code:
<?php
mysql_connect('localhost', 'root', 'Passw0rd') or die(mysql_error());
mysql_select_db("cvtool") or die(mysql_error());
include("include/session.php");
$username = $_SESSION['username'];
?>

it's because of this line
$("#dropDown").change(function(){
add a submit button in the form if that's what you want then run the function off that
<input type="submit" value="Submit" />
Edited after rwacarter's correct comments below about accessability
Add an Id to the form tag
<form id="searchformSubmit"
then do
$("#searchformSubmit").on('submit',function(){
this should also work if the user presses the enter key to submit rather then the button provided you have only the one form on the page
The reason why the page is reloading is because any <button> or or <input type='submit'> inside a HTML form will reload the page, unless you have onClick='return false;' on them. I think you need to add:
onClick="startsearch();return false;"
on the submit button. You'll also have to send the form data with it. To do this, make a variable with this:
var form_data = $('#form').serialize();
and send it with:
$.post('search_result.php', {form: form_data}, function(data) {$("#search").html(data);})
Your ajax call (result search) is called when your dropdown change (click, user input, ...), but you should bind the action to your form click
$(document).ready(function(){
$("#search").click(function(){
var data = $("#dropDown").val();
$.ajax({
type:'POST',
data:'search_value='+data,
url:'search_result.php',
success:function(data){
$("#search").html(data);
}
});
});
});
In addition, this is not necessary to specify the action in your form however it will trigger the form action and redirect you to the page search_result.php, I suggest you to update it and set action="#"
Is this code correct? I want the 'submit' to validate the field (to make sure a value has been entered) and if this is correct (there is a value) then fade and display.
Currently, the form fades even when no value is entered? I feel I'm missing something really simple here!

Judging by your comment on the other answer, you don't care if this actually gets submitted, so you could do the following:
HTML:
<div id="sidebarf">
<form id="sidebarform" name="myForm" method="post">
<input type="text" id="sidebarusername" name="fname" placeholder="Name" />
<input type="submit" id="sidebarformsubmit" value="Submit" />
</form>
JS:
$(document).ready(function() {
$('#sidebarform').on('submit', function() {
if ($('#sidebarusername').val() == '') {
alert('First name must be filled out');
return false;
}
$("#sidebarform").fadeOut("slow", function(){
$("#sidebarf").html("hello " + $("#sidebarusername").val() );
});
return false;
});
});
Working example:
http://jsfiddle.net/3z5x8/
Your validation is bound to the submit event. The click event will always be fullfilled.
Bind your handler to the submit event also
$("#sidebarformsubmit").submit( function(){.....
Unless you are submitting with ajax the form will cause a page refresh also which means your fade and show new html won't work
