how to remove the last word in the string using JavaScript

Question

I would like to know how can I remove the last word in the string using JavaScript?

For example, the string is \"I want to remove the last word.\"

After usin

Answer 1

An easy way to do that would be to use JavaScript's lastIndexOf() and substr() methods:

var myString = "I want to remove the last word";
myString = myString.substring(0, myString.lastIndexOf(" "));

Answer 2

var str = "I want to remove the last word.";
var lastIndex = str.lastIndexOf(" ");

str = str.substring(0, lastIndex);

Get last space and then get sub string.

Answer 3

The shortest answer to this question would be as below,

var str="I want to remove the last word".split(' ');
var lastword=str.pop();
console.log(str.join(' '));

Answer 4

Fooling around just for fun, this is a funny and outrageous way to do it!

"I want to remove the last word.".split(" ").reverse().slice(1).reverse().join(" ")

Answer 5

You can match the last word following a space that has no word characters following it.

word=/s+\W*([a-zA-Z']+)\W*$/.exec(string);
if(word) alert(word[1])

Answer 6

Use split function

var myString = "I want to remove the last word";
var mySplitResult = myString.split(" ");
var lastWord =  mySplitResult[mySplitResult.length-1]
