javascript - How to call the function, if the count reaches the limit -

-

i using google maps , placing map markers using array locations, want call function clearmarkers() if i==26

how can this?

code:

var markers = []; var map; var india = new google.maps.latlng(21.9200,77.9000); var image = 'images/pushpins/set1.png';  function initialize() {   var mapoptions = {     zoom: 5,     center: india   };   map = new google.maps.map(document.getelementbyid('map-canvas'),           mapoptions);   drop(); }  function drop() {   clearmarkers();   (var = 0; < locations.length; i++) {     var city = locations[i][0];     var pro_cat = locations[i][1];     addmarkerwithtimeout(locations[i][2], * 500);       getcity(city,pro_cat, * 500);   } if (i==26){     clearmarkers();   } }  function addmarkerwithtimeout(position, timeout) {   window.settimeout(function() {     markers.push(new google.maps.marker({       position: position,       map: map,       icon: image,       optimized: false,       //animation: google.maps.animation.bounce     }));   }, timeout); }  function clearmarkers() {   (var = 0; < markers.length; i++) {     markers[i].setmap(null);   }   markers = [];   document.getelementbyid('order_list').innerhtml = ""; }  function getcity(city_name, product_cat, timeout){   window.settimeout(function() {   var writecity = document.createtextnode(city_name+', '+product_cat);   document.getelementbyid("order_list").appendchild(writecity);   document.getelementbyid("order_list").appendchild(document.createelement('br'));   }, timeout); } google.maps.event.adddomlistener(window, 'load', initialize);

here using loop call function not working

 function drop() {   clearmarkers();   (var = 0; < locations.length; i++) {           if (i==26){              clearmarkers();           }     var city = locations[i][0];     var pro_cat = locations[i][1];     addmarkerwithtimeout(locations[i][2], * 500);       getcity(city,pro_cat, * 500);       } }

the if statement outside loop i variable not set , comparison 26 return false unless have global i variable. change drop function into:

function drop() {   clearmarkers();   (var = 0; < locations.length; i++) {     var city = locations[i][0];     var pro_cat = locations[i][1];     addmarkerwithtimeout(locations[i][2], * 500);       getcity(city,pro_cat, * 500);     if (i==26){        clearmarkers();     }   } }

the problem expierience bit different. place markers after main function processed. therefore nothing cleared. if remove window.settimout in addmarkerwithtimeout should work.

function addmarkerwithtimeout(position, timeout) {   markers.push(new google.maps.marker({     position: position,     map: map,     icon: image,     optimized: false,     //animation: google.maps.animation.bounce   })); }
