Return array from text in JavaScript

Question

I have one text element and button element. I write 12,34,679 to text element, then press to button. It must alert() the first item of the array, generated from text element. How can I do it? Thanks!

Can you show some code? I don't follow your question. If that is a string, you can get an array out of it with myString.split(',') — Matt Greer

Thank you very much, guys, you all! I solved the problem, with the first answer of @JaredPar! Thank you! I did it with the way, which @JaredPar said, but I think I made a problem, so it didn't work. But know it works perfect! Thanks! — Ziyaddin Sadygly

Assuming that you want to create an array by splitting on commas you can do the following

var text = getTheText();
var array = text.split(',');
var first = array[0];
alert(first);

Use the split method.

<input type="text" id="textElement">12,34,679</input>

var text = document.getElementById('textElement');
var firstIndex = text.split(',')[0];
alert(firstIndex);

very few informations
basically you should use split()
example:

 text = htmlElement.text();
 textArray = text.split(',');
 firstElement = textArray[0];
