Javascript Form validation disabled submit without any framework
I am trying to add my own form validation to this form. The aim is at the end to have these rules:
- If email not valid, display an error.
- If text area < 50 char, display an error.
- If all inputs are invalid, disable the submit.
My first aim is to disable the submit. I tried this with many solutions found in the Internet. Unfortunately, without success. My last try is inspired by this post: https://www.plus2net.com/javascript_tutorial/form-submit-demo.php.
This is my form:
<form name="myForm" action="##" method="post">
<div class="margin_b">
<div class="opinion-radio margin_b">
<span class="label-left">How do you like our pizza?</span> <!-- First element of the form -->
<div class="checkbox-style inputs-right">
<input id="awesome" type="radio" name="review" value="awesome">
<label for="awesome" class="margin-right">Awesome</label>
<input id="good" type="radio" name="review" value="good">
<label for="good" class="margin-right">Good</label>
<input id="ok" type="radio" name="review" value="ok">
<label for="ok"class="margin-right">Ok</label>
<input id="poor" type="radio" name="review" value="poor">
<label for="poor">Poor</label>
</div>
<span id="error-review" class="label-left error">Please select a response.</span>
</div>
<div class="opinion-radio">
<span class="inline, label-left">What do you think about our prices?</span> <!-- Second element of the form -->
<div class="checkbox-style inputs-right">
<input id="fair" type="radio" name="reviewprice" value="fair">
<label for="fair" class="margin-right">Fair</label>
<input id="okay" type="radio" name="reviewprice" value="okay">
<label for="okay" class="margin-right">Okay</label>
<input id="expensive" type="radio" name="reviewprice" value="expensive">
<label for="expensive">Expensive</label>
</div>
<span id="error-reviewprice" class="label-left error">Please select a response.</span>
</div>
</div>
<div class="margin_b">
<label for="name" class=" label-left">Your name:</label> <!-- Third element of the form -->
<input type="text" id="name" name="user_name" class="inline inputs-right">
<span id="error-name" class="error label-left">Please add a name.</span>
</div>
<div class="margin_b">
<label for="name" class=" label-left">Your e-mail address:</label> <!-- Fourth element of the form -->
<input type="email" id="email" name="user_email" class="inline inputs-right">
<span id="error-email" class="label-left error">Please add a correct email.</span>
</div>
<div class="margin_b">
<label for="msg" class="label-left">What can we do better :</label> <!-- Fifth element of the form -->
<textarea id="msg" name="user_message" class="inline inputs-right"></textarea>
<span id="error-text" class="label-left error">Please add a correct text of at least 50 characters.</span>
</div>
<div class="align-right">
<input type="submit" value="Submit" id="btnsubmit">
</div>
</form>
This is my JS (with a first try with the first question of the form):
function formValidation() {
t1ck=true;
if (!document.getElementById("awesome").checked && !document.getElementById("good").checked && !document.getElementById("ok").checked && !document.getElementById("poor").checked ) {
alert("false");
t1ck=false;
}
if (t1ck == false) {
var btnsubmit = document.getElementById("btnsubmit");
btnsubmit.disabled = true;
btnsubmit.style.backgroundColor = "grey";
} else {
t1ck=true;
alert("true");
btnsubmit.disabled = false;
}
}
function submitCheck() {
var awesome = document.getElementById("awesome");
var good = document.getElementById("good");
var ok = document.getElementById("ok");
var poor = document.getElementById("poor");
t1ck=false;
document.getElementById("btnsubmit").disabled = true;
awesome.onclick = formValidation();
good.onclick = formValidation();
ok.onclick = formValidation();
poor.onclick = formValidation();
}
window.onload = submitCheck;
What I discovered is that alert("false"), which is here for debugging purposes) will always be called when the page load, even if this is linked with an onclick event. Furthermore, I never achieved to trigger alert("true").

You define onclick events by calling functions which is wrong.
You need to just use it with function reference without ()
like that:
awesome.onclick = formValidation;
I guess your button disabling will also work then :)
Thanks! This was the correct starting point in order to get it right.
