Javascript get text inside a <span> element

Question

I need to get the text that is inside a element.

I can only grab the class of this element and NOT the ID.

<span class="fileName">test.png</span>

So I need a way to get test.png, but as you see I have only the class of the element and not the ID.

Just notice also that we may have more <span class="fileName"></span>, so it could look like this

<span class="fileName">test1.png</span>
<span class="fileName">test2.png</span>
<span class="fileName">test3.png</span>
<span class="fileName">test4.png</span>

In the case we have more, like the example above, I need to get ALL the values and not only one, because I need to pass this value to another page with jQuery. So it should be able to get one value or more from that element.

Please help!

And also I am not a javascript expert!

Answer 1

var filenames = $('.fileName').map(function(){
    return $(this).text();
}).get();

The array filenames will contain all the names of the images. You can pass on this array to another jQuery function, or anywhere else you like to do so.

You can test it here »

Update

Since you request the filenames to be a string separated by a comma, you can do it like this:

var filenames = $('.fileName').map(function(){
    return $(this).text();
}).get().join(',');

Now, filenames will contain the string test1.png,test2.png,test3.png,test4.png.

Answer 2

Use document.getElementsByClassName: http://jsfiddle.net/pCswS/.

var elems = document.getElementsByClassName("fileName");
var arr = [];
for(var i = 0; i < elems.length; i++) {
    arr.push(elems[i].innerHTML);
}
alert(arr);

(Since you didn't tag the question with jQuery I assume you have to do it with plain JavaScript.)
