What does “javascript:void(0)” mean?
I am checking many sites and I have seen that many website creator define inline JS function "javascript:void(0)". I think this is a difining a JS function which does nothing. example from images.google.com the image inside the search box contains.
<a class="gsst_a" href="javascript:void(0)">
<span id="gs_si0">
<span class="gssi_a gsst_e" id="qbi">
</span>
</span>
</a>
Can anybody explain what is the use of benifit of defining this function even this function does nothing.
