[jQuery] change innerHTML

[jQuery] change innerHTML

<span class="HcCDpe">In my html, I have the following <span> to show upload percentage:
</span><span class="HcCDpe"><span id="progressBarText">0%</span>
I tried to update the percentage using the following javascript:
</span><span class="HcCDpe">$("#progressBarText").innerHTML = "76%";
But it does not work. :(
Thanks.
Arden
