Ways to trigger a JavaScript function upon submission of my form

I have created a code snippet to validate and submit a contact form:

formValidation: function() {
  if (
    this.formData.name && 
    this.formData.company &&
    this.formData.email &&
    this.formData.industry &&
    this.formData.phone &&
    this.formData.inquiryType &&
    this.formData.message &&
    this.formData.captchaResponse
  ) {
    return true;
  }
}

Now, I want to execute another function when the validation returns "true". Should I do it like this:

return true;
return callAnotherFunction();

Or should I create a separate check function like this:

if (formValidation() === true) {
  callAnotherFunction();
}

Answer №1

function validateForm() {
  const formData = this.formData
  return (
    formData.companyName && 
    formData.emailAddress &&
    formData.industry &&
    formData.phoneNumber &&
    formData.inquiryType &&
    formData.message &&
    formData.recaptchaResponse
  )
}

// Return the result
return validateForm() && callAnotherFunction()
// OR if you prefer to store the result in a variable instead of returning it
const isValid = validateForm() && callAnotherFunction()

&& will continue execution until a falsy value is encountered. This means it will return false if validateForm() returns false, or call callAnotherFunction() if it returns true. Using an if-statement is also a valid alternative.

An additional option could be to add one more && at the end of the validateForm() function, like this:

return (... && formData.recaptchaResponse && callAnotherFunction())
. However, it should only be used if it logically ensures that the form is valid.

Answer №2

Insert the invocation of another function within the return clause.

if (...) {
    return callAnotherFunction();
}

Answer №3

Execute function2 only if the function evaluates to true.

if(function()){
  function2();
}
