javascript小书签以在Facebook页面上单击“接受”

Question

I need a javascript bookmarklet that will click the "Yes" button on a facebook page for farmville (or any similar facebook game). The page would say soemthing like "Would you like to accept this gift" and there are three buttons. YEs, Yes and send thank you gift and No. I want to select Yes via javascript.

Information related to the Yes button (pulled from chrome inspector)

<form action="" method="post" style="float: left; text-align: right; width: 30%;" id="app102452128776_form_4c96dd63e3ca077b35e0b"><input type="hidden" name="fb_sig_locale" value="en_US" /><input type="hidden" name="fb_sig_in_new_facebook" value="1" /><input type="hidden" name="fb_sig_time" value="1284955491.9298" /><input type="hidden" name="fb_sig_added" value="1" /><input type="hidden" name="fb_sig_profile_update_time" value="1279260928" /><input type="hidden" name="fb_sig_expires" value="1284962400" /><input type="hidden" name="fb_sig_user" value="100001318363956" /><input type="hidden" name="fb_sig_session_key" value="2.Oh1iDQtbxvGYg3vOpKpRVQ__.3600.1284962400-100001318363956" /><input type="hidden" name="fb_sig_ext_perms" value="email,user_birthday,user_location" /><input type="hidden" name="fb_sig_country" value="us" /><input type="hidden" name="fb_sig_api_key" value="80c6ec6628efd9a465dd223190a65bbc" /><input type="hidden" name="fb_sig_app_id" value="102452128776" /><input type="hidden" name="fb_sig" value="366919f0f771b5fb47303abcb5d6055f" /> 
                <input class="inputyessubmit" type="submit" name="acceptReward" value="Yes" /> 
            </form> 

Answer 1

Based on your snippet above, you'd take this

javascript:(function(){ var b; b=document.getElemenstByName('acceptReward'); if(b.length>0) { b[0].click(); } })()

and paste it into the address bar. This assumes the name acceptReward is unique to that element.

edits: try this. fixed a typo and added some additional checking. that's what I get for coding without intellisense.

javascript:(function(){var b=document.getElementsByName('acceptReward');for(var j=0;j<b.length;j++){if(b[j].value.match(/^Yes$/i)){b[j].click();break;}}})()
