In thinking about a sharing, via email or SMS, component on top of the progress of the recent Javascript Lazy Evaluation Bearing Game Tutorial, with our current … Javascript Lazy Evaluations themed … Drag and Drop themed … Geography Quiz themed … … game modes we thought the best approach would be if a user could share with another the same Geography Quiz based question they have been asked, to compare notes. Which begs the question? What can give a game (or quiz) a random feel? Well, with Javascript, we’re always using … var arandom=Math.floor(Math.random() * anarrayofchoices.length); // anarrayofchoices is an array of choices and arandom ends up as an index into that array’s contents … types of statements … or variations on this style of statement. So we zeroed in on these and set about unrandomising these places in the code, to, if asked, simulate that same random way the question was framed for the emailer … var complex=location.search.split(‘simple=’)[1] ? decodeURIComponent(location.search.split(‘simple=’)[1].split(‘&’)[0]) : ”; var drilldown=complex.split(‘_’)[0]; var simple=location.search.split(‘simple=’)[1] ? (drilldown == ” ? false : true) : false; var mflist=drilldown + ‘_’, mfcount=0; var answer=Math.min(9, eval(Math.floor(Math.random() * 9) + 1)); // first example of use if (complex.indexOf(‘_’ + mfcount + ‘.’) != -1) { answer=eval(complex.split(‘_’ + mfcount + ‘.’)[1].split(‘_’)[0]); } mflist+=” + mfcount + ‘.’ + answer + ‘_’; mfcount++; … used by new helping Javascript code … <div id=das style=display:none;></div> <script type=’text/javascript’> setTimeout(function() { document.getElementById(‘das’).innerHTML+=(“<a style=display:none; id=asms href=’sms:&body=” + encodeURIComponent(document.URL.split(‘#’)[0].split(‘?’)[0] + ‘?simple=’ + encodeURIComponent(mflist)) + “‘>SMS</a>”); document.getElementById(‘bsharesms’).style.visibility=’visible’; }, 18000); setTimeout(function() { document.getElementById(‘das’).innerHTML+=(“<a style=display:none; id=aemail href=’mailto:?subject=Geography%20Quiz&body=” + encodeURIComponent(document.URL.split(‘#’)[0].split(‘?’)[0] + ‘?simple=’ + encodeURIComponent(mflist)) + “‘>Email</a>”); document.getElementById(‘bshareemail’).style.visibility=’visible’; }, 18500); </script> … and will happen for the emailee … function savesms(defsms) { var wasv=(” + window.localStorage.getItem(‘smsgrcg’)).replace(/^null$/g,”).replace(/^undefined$/g,”); if (defsms.indexOf(defsms.trim() + ‘ ‘) == 0) { if (wasv != ”) { window.localStorage.removeItem(‘smsgrcg’); } } else if (defsms.indexOf(defsms.trim() + ‘ ‘) == 0) { if (wasv != ”) { window.localStorage.removeItem(‘smsgrcg’); } window.localStorage.setItem(‘smsgrcg’, defsms.trim()); } else if (defsms == ” && wasv.trim() != ”) { return wasv; } return defsms; } function saveemail(defemail) { var wasv=(” + window.localStorage.getItem(’emailgrcg’)).replace(/^null$/g,”).replace(/^undefined$/g,”); if (defemail.indexOf(defemail.trim() + ‘ ‘) == 0) { if (wasv != ”) { window.localStorage.removeItem(’emailgrcg’); } } else if (defemail.indexOf(defemail.trim() + ‘ ‘) == 0) { if (wasv != ”) { window.localStorage.removeItem(’emailgrcg’); } window.localStorage.setItem(’emailgrcg’, defemail.trim()); } else if (defemail == ” && wasv.trim() != ”) { return wasv; } return defemail; } function smsit() { var smsno=savesms(smsee); if (smsno.trim() != … Continue reading →
