Remove a word from a string

I have a simple string var mystr = "Lorem ipsum dolor sit amet, consectetur adipiscing elit", and I have an array var lipsums = new Array("dolor","consectetur","elit"); Now, I want a simple function which will remove any same word in the string.

So, in the above example, it should remove the words “dolor”, “consectetur”, and “elit” and my string mystr should be "Lorem ipsum sit amet, adipiscing"

This script should be in Javascript (no jQuery). Any help would be appreciated.

Answer 1

Loop over the array of words to remove, removing all occurances via split/join:

for (var i = 0; i < lipsums.length; i++) {
    mystr = mystr.split(lipsums[i]).join('');
}

You may also want to clean up your whitespace afterwards, which you can do with a regex:

// Note: don't do this in the loop!
mystr = mystr.replace(/\s{2,}/g, ' ');
