When I test this form, the function validateJob works correctly, but nothing seems to happen relating to validateCheckbox or validateEmail. I don't get an error.
For this project, I don't need the form to actually do anything but validate. I'm a beginner, so I'm hoping to discover a small fix rather than totally restructuring what I've got so far.
Here is my script:
<script type="text/javascript">
/* <![CDATA[ */
function validateForm(form){
var validation = true;
validation &= validateJob(form);
validation &= validateEmail(form);
validation &= validateCheckbox(form);
return validation;
}
function validateJob(){
var jobSelected=false;
for (var i=0; i<3; ++i) {
if (document.forms[0].job[i].checked == true) {
jobSelected=true;
break;
}
}
if (jobSelected == false) {
window.alert("You must select a job option.");
return false;
}
else {
return true;
}
//function to check check box
function validateCheckbox() {
var contactSelected = false;
if (document.forms[0].contact.checked==true) {
contactSelected=true;
}
if (contactSelected == false) {
window.alert("You must approve being contacted.");
return false;
}
else
return true;
}
//end checkbox check
}
function trim(s)
{
return s.replace(/^\s+|\s+$/, '');
}
function validateEmail() {
var error="";
var tfld = trim(document.forms[0].email);
// value of field with whitespace trimmed off
var emailFilter = /^[^@]+@[^@.]+\.[^@]*\w\w$/ ;
var illegalChars= /[\(\)\<\>\,\;\:\\\"\[\]]/ ;
if (document.forms[0].email.value == "") {
error = "You didn't enter an email address.\n";
} else if (!emailFilter.test(tfld)) {
//test email for illegal characters
error = "Please enter a valid email address.\n";
} else if (document.forms[0].email.value.match(illegalChars)) {
error = "The email address contains illegal characters.\n";
}
window.alert(error);
}
function confirmReset() {
return resetForm;
}
/* ]]> */
</script>
Here is my html:
<form onSubmit="return validateForm(this)">
<p> <label for="name">Full name: </label>
<input type="text" name="fullname"></p>
<p> <label for="email">Email: </label>
<input type="text" name="email"></p>
<p> <label for="job">I am applying to be a: </label><br/>
<input type="radio" name="job">Waiter<br/>
<input type="radio" name="job">Line cook<br/>
<input type="radio" name="job">Other</p>
<p> <label for="contact">Yes, you may contact me </label>
<input type="checkbox" name="contact" ></p>
<input type="submit" value="Submit">
<input type="reset" /></p>
</form>
You can utilize html
required
, title
attributes, adjust <label>
elements placement to after <input>
elements; css
:invalid
, content
, adjacent sibling selector +
:not([type=radio]):invalid + [for]:after { content:attr(title); } [type=radio]:invalid ~ [for]:after, [type=checkbox]:invalid ~ [for]:after { content: attr(title); } :invalid + [for] { color:red; font-style:italic; }
<form> <p> Full name: <input type="text" minlength="1" pattern="\\w+" name="fullname" required /> <label title="You must enter full name" for="name"></label> </p> <p> Email: <input type="text" name="email" required /> <label title="Please enter a valid email address" for="email"></label> </p> <p> I am applying to be a: <br/> <input type="radio" name="job" required />Waiter <br/> <input type="radio" name="job" />Line cook <br/> <input type="radio" name="job" />Other <label title="You must select a job option." for="job"></label> <p> Yes, you may contact me <input type="checkbox" name="contact" required /> <label title="You must approve being contacted." for="contact"></label> </p> <p> <input type="submit" value="Submit" /> <input type="reset" /> </p> </form>
