Iterate through all but one elements in a form












0














I would love my while to iterate through all but one of the elements in the form. This is my code:



while (i < elnum && !empty) {
if (form.elements[i].value == "" && form.elements[i] != form.referral) {
error.innerHTML += 'All fields are required.</br>';
empty = true;
}
i++;
}


Where elnum is the number of elements.



Unfortunately, even if I leave only form.referral empty, it still enters inside the if. Basically, I want the check to be done for all fields but for that one.

    something like if(badField){continue;} should work. Make sure it's the first statement in the if condition.

Rather than trying to compare elements, try something like this:



if( form.elements[i].name == "referral") continue;


Put that just inside the loop, before the condition to check for an empty value.



That being said, it might be better to do something like this:



while(i < elnum) {
if( form.elements[i].hasAttribute("required") && form.elements[i].value == "") {
error.innerHTML += "All fields are required.<br />";
// re-add `empty=true` if the variable is needed elsewhere
// if it's only used to end the loop, then this is better:
break;
}
i++;
}


And make sure you add the required attribute to all required fields. This is a better solution because then it will take advantage of the browser's native ability to handle HTML5 forms, if it has any.
