Searching For A Last Word In Javascript

I am doing some logic for the last word that is on the sentence. Words are separated by either space or with a '-' character. What is easiest way to get it? Edit I could do it by t

Solution 1:

Try splitting on a regex that matches spaces or hyphens and taking the last element:

var lastWord = function(o) {
  return (""+o).replace(/[\s-]+$/,'').split(/[\s-]/).pop();
};
lastWord('This is a test.'); // => 'test.'lastWord('Here is something to-do.'); // => 'do.'

As @alex points out, it's worth trimming any trailing whitespace or hyphens. Ensuring the argument is a string is a good idea too.

Solution 2:

Using a regex:

/.*[\s-](\S+)/.exec(str)[1];

that also ignores white-space at the end

Solution 3:

Have you tried the lastIndexOf function http://www.w3schools.com/jsref/jsref_lastIndexOf.asp

Or Split function http://www.w3schools.com/jsref/jsref_split.asp

Here is a similar discussion have a look

Solution 5:

You can try something like this...

<scripttype="text/javascript">var txt = "This is the sample sentence";
spl = txt.split(" ");
for(i = 0; i < spl.length; i++){
    document.write("<br /> Element " + i + " = " + spl[i]); 
}
</script>
