[英]delete specific marker in google map dynamically
I have faced to the problem and I was suffering this issue, but I didn't get an answer. 我已经面对了这个问题,并且正在遭受这个问题的困扰,但是我没有得到答案。 I have the point and each point has a category.
我有要点,每个要点都有一个类别。 And I need do display this data from the filter: when we came at page loaded -all points, when we select a category through the filter - on the map need display points that belong selected categories.
我需要显示来自过滤器的数据:当我们到达页面加载页面时-所有点,当我们通过过滤器选择类别时-在地图上需要显示属于所选类别的显示点。 I check if unchecked category id equivalent to markers category id.
我检查未经检查的类别ID是否等于标记的类别ID。 But markers not delete.
但是标记不会删除。 What I doing wrong?
我做错了什么? Here is my code:
这是我的代码:
function ajaxLoad(dataForm,urlAction,flag){
$.ajax({
data:dataForm,
type: 'POST',
url:urlAction,
success:function(data){
var data = JSON.parse(data);
var i;
var a;
// get all unchecked categories
var unchecked = ($("input:checkbox:not(:checked)"));
markers = [];
for (i = 0; i < data.length; i++) {
point = new google.maps.LatLng(data[i][1], data[i][2]);
marker = new google.maps.Marker({
position: point,
icon:data[i][4],
title:data[i][0],
//id category
id:data[i][5]
});
var content;
if(data[i][3]) {
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
infowindow.setContent(data[i][3]);
infowindow.open(map, marker);
}
})(marker, i));
}
marker.setMap(map);
marker.setMap(null);
markers[i] = marker;
if(flag === true){
for (a = 0; a < unchecked.length; a++) {
var marker = markers[i];
//check if unchecked category id == markers category id
if(markers[i].id != unchecked[a].value){
marker.setMap(null);
}
}
}
}
map.setCenter(marker.getPosition());
},
error:function(data){console.log(data)}
});
}
$(document).ready(function(){
map = new google.maps.Map(document.getElementById('map'), {
zoom: 13,
center: new google.maps.LatLng(50.7498176,25.3192401),
mapTypeId: google.maps.MapTypeId.ROADMAP,
scrollwheel: false,
});
infowindow = new google.maps.InfoWindow();
//show all
ajaxLoad(1,"<?php echo Yii::app()->controller->createUrl('/advertise/default/getMap')?>",false);
($('input[type="checkbox"]').on('click',function(){
var data = $('#form-filter').serialize();
//filter category
ajaxLoad(data,"<?php echo Yii::app()->controller->createUrl('/advertise/default/filterMap')?>",true);
} ));
});
I resolved it! 我解决了! Just set:
刚刚设置:
for(i=0; i<markers.length; i++){
markers[i].setMap(null);
}
before ajax query and remove that piece: 在ajax查询之前,删除该部分:
if(flag === true){
for (a = 0; a < unchecked.length; a++) {
var marker = markers[i];
//check if unchecked category id == markers category id
if(markers[i].id != unchecked[a].value){
marker.setMap(null);
}
}
