You could use a regular expression for that. It takes the first four words and adds some dots,

var text = 'The style of this paper is a combination of an external stylesheet, and internal style.';
document.write(text.replace(/^((\w*\W*){0,4}).*/, '$1...'));

You can create a function which returns the first N words from the text of an element. For example:

function firstWords(wrapperId, wordCount) {
    var element = document.getElementById(wrapperId);
    var textArray = element.textContent.split(/\s/);
    if(textArray.length >= wordCount) {
        return textArray.slice(0, wordCount).join(" ");
    } else {
        return textArray.join(" ");
    }
}

Afterwards if the wrapper has ID "foo" for example as

<div id="foo">This is a sample text!</div>

you can call

console.log(firstWords("foo", 4));

use 

strArr[] = str.split(" ");

str[0] , str[1], str[2], str[3] is the resultant what you want to use.
