Ways to determine the data type of a textarea

I encountered an issue while working with a script; here is the code snippet in question:

if (form.elements[i].type === 'text') {
// do stuff
}

The code works as expected for input type=text, but not for textarea. I tried modifying it like this:

if (form.elements[i].type === 'text' && form.elements[i].type === 'textarea') {
// do stuff
}

Despite the modification, the code still does not work on textarea elements. Any suggestions or ideas to resolve this issue would be greatly appreciated.

Answer №1

The reason for this is that <textarea> elements do not possess a type property. It is important to verify the element name instead, using

form.elements[i].tagName === 'TEXTAREA'
. (Note that tagName always returns in all caps.)

Additionally, it is crucial to utilize the || operator rather than && as an element cannot simultaneously satisfy both conditions!

Answer №2

The reason lies in the necessity for verifying that the type is both text and textarea. To achieve this, consider using the or-operator in the following way:

if (form.elements[i].type === 'text' || form.elements[i].type === 'textarea') {
    // perform actions
}
