Javascript 使Google maps标记数组全局中断标记单击事件
在本文中,我使用以下脚本:Javascript 使Google maps标记数组全局中断标记单击事件,javascript,jquery,google-maps,Javascript,Jquery,Google Maps,在本文中,我使用以下脚本: function initialize() { var mapCanvas = document.getElementById('map'); var mapOptions = {center:new google.maps.LatLng(latitudeMid,longitudeMid),zoom:15,mapTypeId:google.maps.MapTypeId.ROADMAP,streetViewControl:false,mapTypeControl
function initialize() {
var mapCanvas = document.getElementById('map');
var mapOptions = {center:new google.maps.LatLng(latitudeMid,longitudeMid),zoom:15,mapTypeId:google.maps.MapTypeId.ROADMAP,streetViewControl:false,mapTypeControl:true,scaleControl:true,scaleControlOptions:{position:google.maps.ControlPosition.TOP_RIGHT}};
var map = new google.maps.Map(mapCanvas, mapOptions);
var markers=[]; //<=========================================== inside function initialize()
var i;
var insertion;
var previousMarker;
for (i = 0; i < fotoCount; i++) {
var myLatLng=new google.maps.LatLng(Latituden[i], Longituden[i]);
var marker = new StyledMarker({styleIcon:new StyledIcon(StyledIconTypes.MARKER,{color:'00ff00',text:Letters[i]}),position:myLatLng,map:map});
marker.set('zIndex', -i);
marker.myIndex = i;
markers.push(marker);
google.maps.event.addListener(marker, 'click', function() {
var insertion="";
insertion='<img src=\"http://www.pdavis.nl/Ams/'.concat(Bestanden[this.myIndex],'.jpg\"></img>');
insertion=insertion.concat('<table class=width100><tr><td>Bestand: ',Bestanden[this.myIndex],'</td><td class=pright>Lokatie: ',Latituden[this.myIndex],' °N., ',Longituden[this.myIndex],' °E. (',Letters[this.myIndex],')</td>');
insertion=insertion.concat('<td class=pright>Genomen: ',Datums[this.myIndex],'</td></tr><td colspan=3>Object: ',Objecten[this.myIndex],'</td></table>');
$('#photo').html(insertion);
if(previousMarker!=null){previousMarker.styleIcon.set('color', '00ff00')};
this.styleIcon.set('color', 'ff0000');
thisMarker=this.myIndex;
previousMarker=this;
});
}
google.maps.event.trigger(markers[0], 'click');
}
google.maps.event.addDomListener(window, 'load', initialize);
显而易见的修复方法是将“var markers=[]”移动到函数initialize()外部(第页),使该数组成为全局数组,但现在突出显示的按钮(按钮“A”在启动时变为红色;单击的按钮变为红色)不起作用。我在这里做错了什么?唯一奇怪的事情不是当你将索引0传递到最大值时,点击事件爆炸,因为他发送了一个负值,然后改变它,想知道它是否是-1,如果真的传递了更大的索引-1(Excepcion:Cannot read属性'\uuuuuuue3ae\uuuu') 对不起,我的英文可能重复;使用函数闭包将标记与单击侦听器关联。Hello Alimentador:谢谢(我看的方向错了!)
function Next() {
thisMarker++;
if (thisMarker>=fotoCount) {thisMarker=0};
// following line not working
google.maps.event.trigger(markers[thisMarker], 'click');
}
function Previous() {
thisMarker--;
if (thisMarker==0) {thisMarker=fotoCount-1};
// following line not working
google.maps.event.trigger(markers[thisMarker], 'click');
}
function Previous() {
thisMarker--;
if (thisMarker==-1) {thisMarker=fotoCount-1};
// following line not working
google.maps.event.trigger(markers[thisMarker], 'click');
