Question

I want to extract text from span elements with no class name. How can it be done?
Elements with particular class name can be searched but how to get only the elements with no class name for them?

<span>0m2abBrL+RIHOEA+dZS+OqV3St+nJ/</span>
<wbr></wbr>
<span class="word_break"></span>
<span>zwq73Gfz8MQGB0yS++lfufSOV133huE</span>
<wbr></wbr>
<span class="word_break"></span>
vCB0s5D9w
<span class="text_exposed_hide">...</span>

Answer 1

Iterate through them and check the classname I suppose.

var spans = document.getElementsByTagName('span');
for (var i = 0; i < spans.length; i++) {
    if (spans[i].className == '') {
        //span doesn't have a class
    }
}
