谷歌地图折线infowindow [英] google map polyline infowindow
问题描述
作为这个问题的延续,我试图将各自的json对象名称添加到infowindow内容为,
var infowindow = new google.maps.InfoWindow({
content:i
} );
这个小提琴,但它只显示最后一个物体的名字。我也尝试使用 return
函数作为
google.maps.event。 addListener(poly,'click',(function(event,(poly,i)){
return function(){
infowindow.open(map);
infowindow.setPosition(event。 latLng);
}
})(poly,i));
但没有用(小提琴)。我怎样才能实现它?
你说:但所有括号都正确关闭。。这是不正确的(你在函数定义中有一个额外的圆括号):
google.maps.event.addListener( poly,'click',(function(event,(poly,i)){
return function(){
infowindow.open(map);
infowindow.setPosition(event.latLng) ;
}
})(poly,i));
事件
参数属于返回的函数,并且只需要在多边形( poly
)和循环索引( i
)上关闭:
pre $ lt; code> google.maps.event.addListener(poly,'click',(function(poly,i){
return function(event ){
infowindow.setContent(+ i);
infowindow.setPosition(event.latLng);
infowindow.open(map);
};
})(poly,i));
As continuation to this question, i trying to add the respective json object name to infowindow content as,
var infowindow = new google.maps.InfoWindow({
content:i
});
Which is given in this fiddle but it displays only the name of last object. I also tried with return
function as
google.maps.event.addListener(poly, 'click', (function(event, (poly, i)) {
return function() {
infowindow.open(map);
infowindow.setPosition(event.latLng);
}
})(poly, i));
but no use (fiddle). How can I achieve it?
You said "But all brackets are correctly closed.". This is not correct (you have an extra set of parentheses in the function definition):
google.maps.event.addListener(poly, 'click', (function(event, (poly, i)) {
return function() {
infowindow.open(map);
infowindow.setPosition(event.latLng);
}
})(poly, i));
The event
argument belongs to the returned function, and you only need closure on the polygon (poly
) and the loop index (i
):
google.maps.event.addListener(poly, 'click', (function (poly, i) {
return function (event) {
infowindow.setContent(""+i);
infowindow.setPosition(event.latLng);
infowindow.open(map);
};
})(poly, i));
