Would you like to get the inner text of the targetted elements? — Jeroen Bellemans, Oct 25 '15 at 12:39

To get the inner text, you can use the text() function, like this:

HTML:

<span class="memName fn">Ankur Arora</span>

Jquery:

var memName = $(".memName").text();
console.log(memName); // Via console log
alert(memName); // Alert it

It's easy with jQuery. Just include it in your page:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>

Then use .text() or .html() to extract the content of the span-elements

var pictureLink = $("span[itemprop='image']").text();
//.html() also gets the html-elements inside
var name = $("span[itemprop='name']").html();

Hello Chris Breaks, thanks for your answer, but its not working... first I need to search the class in the page no?? – benhi Oct 26 '15 at 07:15
I can't think of a way why this wouldn't be working (see the jsfiddle-link). Do you get javascript-errors? Generally speaking: You can address elements in different ways. for example by id, by classname, by position relative to other elements, or in this case by your unique attribute `itemprop`. a good way to debug your script is by passing out data with `console.log("data")` at vital positions. – Chris Breaks Oct 26 '15 at 07:33

You can also use innerHTML to get the text.

<span id="memId" class="memName fn">Ankur Arora</span>

document.getElementsByClassName('memName') - This will give the list of elements having the class 'memName'

To get the first element's inner text use document.getElementsByClassName('memName')[0].innerHTML

or access by id .

document.getElementById('memId').innerHTML
