web - How to make a URL with javascript variable? -


i trying pass javascript variable url, there sort of syntax error within it.

function initmap() {   var jsondata = { $tourarray }   var map = new google.maps.map(document.getelementbyid('map'), {     zoom: 4,     center: {       lat: jsondata.centerlat,       lng: jsondata.centerlon,     },   })    var kml = jsondata.kmlfile   var src = 'http://www.example.com/kml/?= + kml'    var kmllayer = new google.maps.kmllayer(src, {     map: map,   }) }

the variable var kml kml file name stored on server within folder kml , trying access file in order add kml layer on google map.

the url syntax seems incorrect.

you missed it. 

var src = "http://www.example.com/kml/?=" + kml;

if you're using es6, template literals makes cleaner.

var src = `http://www.example.com/kml/?=${kml}`
