Remove after a particular String

I have some text content 

atxtCtnt = "Helow Hay How Are You"

if Hay exists I need to remove Hay How Are You

I did it like this: 

var atxtCtnt = "Helow Hay How Are You",
txt = atxtCtnt.substring(atxtCtnt.indexOf("Hay"));
atxtCtnt = atxtCtnt.replace(txt , "");
alert(atxtCtnt );

Please help me in better way without RegExp

This should work:

atxtCtnt = atxtCtnt.substring(0, atxtCtnt.indexOf("Hay"));

Edit: To account for if Hay isn't there:

atxtCtnt = atxtCtnt.substring(0, atxtCtnt.indexOf("Hay") === -1 ? atxtCtnt.length : atxtCtnt.indexOf("Hay"));

var word = "Hay";
var a = "Helow Hay How Are You";
var b = a.split(word); // now you have two parts b[0] = Helow and b[1] = How Are You
document.body.innerHTML=b[0];

You need the sub string from 0 to the index. But only if the index is more than 0 (The term "Hay" exists in the text). Like this

var atxtCtnt = "Helow Hay How Are You";
var index = atxtCtnt.indexOf("Hay");
var newText = (index < 0) ? atxtCtnt : atxtCtnt.substring(0, index);
alert(newText);

I'm not sure if this is better solution than this with substrings, but you can also try this:

atxtCtnt.split('Hay')[0]

You can remove whitespace at the end of "Helow " like this:

atxtCtnt.split('Hay')[0].trim()

If you don't want to use Regex... I think this will make your code a little bit shorter

a = atxtCtnt.indexOf('Hay');
atxtCtnt = a >=0?atxtCtnt.substring(0,a):atxtCtnt;
