javascript - Google maps, passing "map" to a different event -

-

i have 2 different events, please correct me if doing wrong,

    //initializing map     google.maps.event.adddomlistener(window, 'load', initialize);      //initializing markers     google.maps.event.addlistener(map, 'idle', showmarkers);

the first event initialize map (set up), second event querying database new markers when current map bounds change (not functional yet)

since have defined "map" inside initialize function, how can access outside function , pass second event? can see have declared before functions global variable still undefined event argument, have been stuck on days

var map; function initialize(){         //defining map options         var maplatlng = new google.maps.latlng(37.09024, -100.712891);         var mapoptions = {             zoom: 4,             center: maplatlng         }         //defining map         map = new google.maps.map(document.getelementbyid('map-canvas'), mapoptions);     }      function showmarkers(){          parse.initialize("x","x");          var query = new parse.query("business_and_reviews");         var results = new parse.object("business_and_reviews");          query.equalto("name","mcdonalds");          query.find({             success: function(results) {                 console.log(results);                  (var = 0; < results.length; i++) {                     var object = results[i];                 }                  var lat = (object["attributes"]["lat"]);                 var lng = (object["attributes"]["lng"]);                  console.log(lat);                 console.log(lng);                  //adding marker query                 var marker = new google.maps.marker({                     position: maplatlong,                     map: map,                     title: 'hello world!'                 });              },             error: function(object, error) {             }         });      }     //initializing map     google.maps.event.adddomlistener(window, 'load', initialize);      //initializing markers     google.maps.event.addlistener(map, 'idle', showmarkers);

for second event "map" undefined

solved it! put idle event listener inside initialize function , works charm! guess initilize isn't initialize page runs constantly

PHP DOM loadHTML() method unusual warning -

i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null
