How do I go about having this not submit when nothing is checked, but then having it submit when one is checked? It currently submits either way. What am I missing here? It throws up the error I want it to when nothing is checked "Please check one of the options above" but then goes to the landing page. Thank you for any help!
$(document).ready(function () {
$("#submitbutton").click(function () {
var none_answered = true;
$("input:radio").each(function () {
var name = $(this).attr("name");
if ($("input:radio[name]:checked").length == 0) {
none_answered = false;
}
});
if (none_answered == false) {
$('#texthere').html("Please check one of the options above");
}
})
});
<style type="text/css">
#texthere
{
color:red;
}
</style>
<body>
<form>
<input type="radio" name="refer" value="Strategic Communication" >Strategic Communication</br>
<input type="radio" name="refer" value="Journalism" >Journalism</br>
<input type="radio" name="refer" value="Communication Studies" >Communication Studies</br>
<div id="texthere"></div>
<input id="submitbutton" type="submit" value="submit" formaction="http://www.utah.edu/">
</form>
</body>
When you want to prevent the default behaviour use .preventDefault(). For example in your case a form submit event, if you want to validate inputs before form post and stop submitting form if any errors, use event.preventDefault().
Try this:
$(document).ready(function () {
$("#submitbutton").click(function (e) {
var none_answered = true;
$("input:radio").each(function () {
var name = $(this).attr("name");
if ($("input:radio[name]:checked").length == 0) {
e.preventDefault();
none_answered = false;
}
});
if (none_answered == false) {
$('#texthere').html("Please check one of the options above");
}
})
});
