Google Maps API v3 - Mousemove和Click事件组合 [英] Google Maps API v3 - Mousemove and Click event Combo
问题描述
如果我将一个点击事件连接到我的地图,然后挂钩了一个mousemove事件,则click事件不再起作用。我不认为有人知道这件事吗?这是在3.4版本的方式。
一个简单的例子:
var map;
函数initialize(){
var myLatlng = new google.maps.LatLng(-34.397,150.644);
var myOptions = {
zoom:8,
center:myLatlng,
mapTypeId:google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById(map_canvas),myOptions);
var secondClick = false;
var firstClick = false;
var firstClickLatLng;
var secondClickLatLng;
var lines = [];
google.maps.event.addListener(map,'mousemove',function(event){
redrawLine(event);
});
google.maps.event.addListener(map,'click',function(event){
if(!firstClick&&!secondClick){
firstClick = true ;
firstClickLatLng = event.latLng;
}
else if(firstClick&&!secondClick){
secondClick = true;
firstClick = false;
//在此处绘制折线
secondClickLatLng = event.latLng;
//google.maps.event.removeListener (listener);
}
else if (!firstClick&&secondClick){
secondClick = false;
//在此清除折线
alert(what);
//google.maps.event .removeListener(listener);
}
});
函数redrawLine(事件){
if(firstClickLatLng!= null){
var lineCoords = [
firstClickLatLng,
event.latLng
];
var line = new google.maps.Polyline({
path:lineCoords,
strokeColor:#FF0000,
strokeOpacity:1.0,
strokeWeight:2
});
//您需要清除前一行,否则
//会绘制负载和线条负载。我做了这个
//以防因为某种原因无法清除之前的
// //。
for(var i = 0; i< lines.length; i ++){
lines [i] .setMap(null);
}
line.setMap(map);
lines.push(line);
$ b因此,每当你移动鼠标。问题是,如果我第二次点击,点击事件不会触发。
想法?

虽然它并没有明确地解决我的问题,但其他人已经测试并体验过这种感觉。
解决方案排序,如链接所示,您需要声明可点击:false

If I've got a click event hooked up to my map, and then I hook up a mousemove event, the click event no longer works. I don't suppose anyone knows anything about this? This is in version 3.4 by the way.
As a simple example:
var map;
function initialize() {
var myLatlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var secondClick = false;
var firstClick = false;
var firstClickLatLng;
var secondClickLatLng;
var lines = [];
google.maps.event.addListener(map, 'mousemove', function (event) {
redrawLine(event);
});
google.maps.event.addListener(map, 'click', function (event) {
if (!firstClick && !secondClick) {
firstClick = true;
firstClickLatLng = event.latLng;
}
else if (firstClick && !secondClick) {
secondClick = true;
firstClick = false;
// draw the polyline here
secondClickLatLng = event.latLng;
//google.maps.event.removeListener(listener);
}
else if (!firstClick && secondClick) {
secondClick = false;
// clear the polyline here
alert("what");
//google.maps.event.removeListener(listener);
}
});
function redrawLine(event) {
if (firstClickLatLng != null) {
var lineCoords = [
firstClickLatLng,
event.latLng
];
var line = new google.maps.Polyline({
path: lineCoords,
strokeColor: "#FF0000",
strokeOpacity: 1.0,
strokeWeight: 2
});
// You need to clear the previous line, otherwise
// it draws loads and loads of lines. I did this
// in case it doesn't manage to clear the previous
// one for some reason.
for (var i = 0; i < lines.length; i++) {
lines[i].setMap(null);
}
line.setMap(map);
lines.push(line);
}
}
}
So a line is drawn for whenever you move the mouse. The problem is that if I were to click for the second time, the click event will not fire.
Ideas?

It doesn't explicitly solve my problem though, but others have tested and experienced this.
解决方案 Sorted, as that link showed, you need to state clickable: false
