For a <input type="text" id="vegs" name="fruits">, it is possible to use document.getElementbyId('vegs').value to get the input of the text box. But is there a way to get input by using the name attribute of the <input>tag? document.getElementsbyName('fruits').value doesn't seem to work.

document.getElementsByName returns a NodeList (which is like an array), so you need to select the first item.

There could be multiple inputs with name of fruits. If that is the case, iterate over the NodeList just like you would iterate over an array.

I made a snippet for you:

document.getElementById("button").addEventListener("click", () => {
  console.log(document.getElementsByName("fruits")[0].value);
});
<input type="text" id="vegs" name="fruits">
<button id="button">Click</button>

Comments
  • document.getElementsByName('fruits')[0].value
  • @MegCullen no problem. With DOM, if the .getElements is plural, it returns a NodeList. Otherwise, it returns a single item
  • So that means we can have multiple tags with same name and call the value as required using [#]...is that right?
  • @MegCullen Right. I'll make a snippet for you in my answer demonstrating that right now
  • @MegCullen ok I updated my answer. Look at the second snippet.
