Toggling on/off Markers in Google Maps API v3 -

-

i'm having trouble getting setmap(null); function seems recommending work.

i believe may problem way i've implemented markers.

if take , let me know if see wrong i'd appreciate it.

please note: old link above, doesn't go anywhere.

the basic problem if want work you've got make mind markerstest object supposed hold. can't seem decide whether elements in markerstest should markers or should arrays tell markers going placed.

quoting javascript file, here 2 functions executed when check/clear checkbox:

15  function addtestmarkers(){ 16      for(var in markerstest) { 17          var location = new google.maps.latlng(markerstest[i][1], markerstest[i][2]); 18          marker = new google.maps.marker({ 19              position: location, 20              map: map 21          }); 22      } 23  } 24   25  // removes overlays map, keeps them in array 26  function clearoverlays() { 27      if (markerstest) { 28          (i in markerstest) { 29              markerstest[i].setmap(null); 30          } 31      } 32  }

for addtestmarkers work, markerstest object needs hold descriptions of markers should go. clearoverlays work, markerstest object needs hold markers.

here's suggestion: change markerstest object set @ top of javascript file markerdestinations, , @ top of javascript file have markerstest initialized with:

markerstest = {};

then, modify addtestmarkers to:

function addtestmarkers() {     for(var in markerdestinations) {         var location = new google.maps.latlng(markersdestinations[i][1], markersdestinations[i][2]);         markerstest[i] = new google.maps.marker({             position: location,             map: map         });     } }

the key change make addtestmarkers put markers markerstest object.

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
