i trying change innerhtml anchor text not changing....

html:

<div style="float:right;">     <a id="grablinkall" onclick="showall()" href="#">show all</a> </div>

javascript:

function showall() {     var thedropposition = document.getelementbyid('grablinkall');     if (thedropposition.innerhtml == "show all") {         thedropposition.innerhtml == "hide all";     } else {         thedropposition.innerhtml == "show all";     } }
