And here's the code if anyone is interested in how it works: javascript:!function(){if('https://twitter.com'!==window.location.origin||4!==window.location.

  More readable version of the code: ( function () { // Exiting if the webpage is not Twitter or a valid tweet if (window.location.origin !== 'https://twitter.com' || window.location.pathname.split('/').length !== 4) return alert('This is not a valid Twitter poll!'); alert("Please wait this can take up to 30 seconds. Select OK or close to get started. If this is a valid poll, you will get the result when it is ready...:)"); // This string will hold our poll result let result = ''; // This boolean denotes if our job is done and if true, doesn't execute the addEventListener anymore. let processDone = false; let oldXHROpen = window.XMLHttpRequest.prototype.open; const startTime = Date.now(); window.XMLHttpRequest.prototype.open = function () { if (processDone) { return oldXHROpen.apply(this, arguments); } // onLoad event handler to intercept the Twitter API response to read the poll results. function listenEvent() { try { if (this.responseURL.includes('poll')) { // JSON from the Twitter API response // On a poll page every 30 seconds, Twitter hits the API to retrieve the latest poll results const pollResultJson = JSON.parse(this.responseText); const pollBindingValues = pollResultJson.card.binding_values; const resultObj = Object.keys(pollBindingValues).reduce(function (accum, key) { if (key.includes('_label')) { const label = pollBindingValues[key].string_value; const choiceNumber = key.replace(/\D/g, ''); const voteCount = pollBindingValues[`choice${choiceNumber}_count`].string_value; accum.choiceVoteCountMap[label] = +voteCount; accum.noOfVotes += +voteCount; } return accum; }, { noOfVotes: 0, choiceVoteCountMap: {} }); const { choiceVoteCountMap, noOfVotes } = resultObj; Object.keys(choiceVoteCountMap).forEach(function (label) { result += `${label}: ${((choiceVoteCountMap[label] / noOfVotes) * 100).toFixed(2)}%\n` }) } } catch (e) { processDone = true; // For error reporting. Incase if the bookmarklet fails to work in future, people will be able to report...:) if (window.confirm("Something went wrong. Could you please report the issue?")) { window.open("https://www.syncwithtech.org/twitter-poll-result-wo-voting/", "_blank"); } this.removeEventListener('load', listenEvent); } } this.addEventListener('load', listenEvent); // If result holds proper string, we need to stop listening to the event if (result) { processDone = true; alert(result); this.removeEventListener('load', listenEvent); } // If the page is a proper tweet and doesn't have a poll, we must stop listening to the load event. It happens after 40 seconds. if (Date.now() - startTime > 40000 && !processDone) { processDone = true; // To get feedback if it's actually a poll and the script fails to detect it if (window.confirm("Seems like it is not a valid Twitter poll. Press OK to report the issue if it is a valid poll and the bookmarklet failed to detect it.")) { window.open("https://www.syncwithtech.org/twitter-poll-result-wo-voting/", "_blank"); } this.removeEventListener('load', listenEvent); } return oldXHROpen.apply(this, arguments); } } )();
