javascript - Check for checkbox value after Google Map has loaded -


i think i'm missing basic javascript. use help!

scenario: after clicking "search" google map loads. loads, checkbox appears says, "redo results when map moved" (similar yelp). if map dragged or zoomed, results update. part works fine.

problem: value of checkbox (true or false) recognized redo() function when map loads, , doesn't check again after (because though redo() updating results it's not reloading map). if toggle checkbox, "redo" function doesn't notice!

simplified code:

//haml %input{:type => "checkbox", :id => "followcheck", :name => "followcheck", :onclick => 'handleclick();'}  //load map function showlocations() {    map = new google.maps.map(document.getelementbyid("map_canvas"), {     bunch of map stuff;     map.fitbounds(bounds);     redo(); //this redo function, see below   } }  function handleclick(checkbox) {   var chk = document.getelementbyid("followcheck").checked;   console.log("checkbox value " + chk);   return chk; }  function redo() {   var chk = handleclick();   console.log("inside redo, value " + chk);    if (chk == true) {      google.maps.event.addlistener(map, 'mouseup', function() {        mapadjusted = 1;        updatemapafteruserinteraction();      });      google.maps.event.addlistener(map, 'zoom_changed', function() {        mapadjusted = 1;        updatemapafteruserinteraction();      });    } }

(note, redo() function written collaborator, smarter me , out of town.)

so, redo() loads when map loads. if checkbox true when map loads, redo() function processes zoom/drag. still after changing value false (and if value false when page loads, opposite happens).

what needed redo() see value has changed? push()? bind()? get/set? change()? addeventlistener()? should reload map when checkbox toggled (i'd rather not)? whole new approach? i'm stuck! thanks. i'm open jquery ideas, too.

i solved this. first off, small adjustment function able turn on after checking box (even if results loaded while box unchecked via previous page session). here code (i found 3 variations had same result):

function redo() {   if ($("#followcheck").is(':checked')) {     google.maps.event.addlistener(map, 'mouseup', function() {       mapadjusted = 1;       updatemapafteruserinteraction();     });     google.maps.event.addlistener(map, 'zoom_changed', function() {       mapadjusted = 1;       updatemapafteruserinteraction();     });   } }

the problem didn't turn off. , that's because i've added 2 listeners! this answer helped me remove listeners. note (for me) worked when removelistener() function within addlistener() function. kind of strange.

function redo() {   var listener1 = google.maps.event.addlistener(map, 'mouseup', function() {     if (!$("#followcheck").is(':checked')) {       google.maps.event.removelistener(listener1);     } else {       mapadjusted = 1;       updatemapafteruserinteraction();     }   });   var listener2 = google.maps.event.addlistener(map, 'zoom_changed',  function() {     if (!$("#followcheck").is(':checked')) {       google.maps.event.removelistener(listener2);     } else {       mapadjusted = 1;       updatemapafteruserinteraction();     }   }); }

oh , changed onclick() onchange()
