Click on button

Hello

I want to click on the button "Abandonner la modification"; there's no form in the code.

Could you help me, please ?

Thanks



<input type="button" value="Abandonner la modification" onclick="if(isLinkNotClicked()){if (!prepareAnnuler('')){setLinkClickedFalse();return false;} else{return true;}} else {return false};" onmouseover="this.className='buttonOver';showmessage(gsInfoBulleAnnulerModificationEC, null, true);" onmouseout="this.className='button';hideticker();" class="button"/>
