javascript - Two $.getJSON calls for one Google Maps api info window. Scope issue -

-

i trying call $.getjson twice , use data both in 1 info window. mashup display articles google news "fortune" (from rss feed) in google maps api infowindow. put click event listener , info window blocks inside $.getjson("articles.php") call code below works in far display articles can't figure out right structure display fortune since it's in separate $.getjson it's own scope. there way make work?

function addmarker(place) {      var image = 'http://maps.google.com/mapfiles/kml/pal2/icon31.png';       var mylatlng = new google.maps.latlng(parsefloat(place.latitude), parsefloat(place.longitude));     //make markers , push array.      var marker = new markerwithlabel({     position: mylatlng,     map: map,     icon: image,     labelclass: "labels",     labelcontent: place.place_name,     labelanchor: new google.maps.point(20,0),         });      markers.push(marker);      // getjson fortune rss feed.      var fortune = [];      $.getjson("fortunes.php").done(function(data, textstatus, jqxhr) {         var content = data;         var len = data.length;         if (content.length < 1)         {             var fortune = "test";         }         else         {             fortune = content;         }      });          // getjson articles google news rss feed.      var query = place.postal_code;     var articles = "news service unavailable.";     var parameter = { "geo": query };     $.getjson("articles.php", parameter).done(function(data, textstatus, jqxhr) {         var content = data;         var len = data.length;         if (content.length < 1)         {             articles = "slow news day."         }         else         {             articles = "<ul>";             // put articles in unordered list             (var = 0; < len; i++) {                 articles += "<div><li> <a href=\"" + data[i].link + "\" target=\"_blank\">" + data[i].title + "</li></div>";             }             articles += "</ul><div><p>fortune</p><p>" + fortune.length + "</p></div>";         }         // listener info window             google.maps.event.addlistener(marker, 'click', function() {             infowindow.open(map,marker);         });         // info window          var infowindow = new google.maps.infowindow({             content: articles         });       });   }

there 4 ways done.

  1. make ajax calls sequentially - see code example below or http://jsfiddle.net/xs0oypmd/
  2. build marker window content when user opens it, move articles html building code within marker click event listener , use setcontent function on infowindow. if going approach i'd suggest using flag indicate first time info window opened articles html built once. approach have limitation still not know if fortunes has loaded.
  3. make "fortunes" call within "articles.php" - assumes ownership on php scripts. approach means 1 ajax call browser.
  4. use model binding framework, e.g. knockout, update infowindow content when data updated via json call

code example option 1

$("#btngetarticles").on("click", function(){     var fortunes = "test";      $.ajax({         url: "/echo/json/",         type: 'post',         datatype: 'json',         data: {             json: '"some fortune"'         }     }).done(function(data) {         fortunes = data;          $.ajax({             url: "/echo/json/",             type: 'post',             datatype: 'json',             data: {                 json: '[{"link": "link/to/first/article", "title" : "first article"},{"link": "link/to/second/article", "title" : "second article"},{"link": "link/to/third/article", "title" : "third article"}]'             }         }).done(function(articles) {             var articleslist = $("<ul />");             $.each(articles, function(i, v) {                 articleslist.append($("<li />").html(v.title + ' ' + fortunes.length));             });              $("#output").append(articleslist);         });     }); });

java - UML - How would you draw a try catch in a sequence diagram? -

Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
