我正在使用jVectorMaps。默认情况下,它不允许选择区域UNLESS>>> regionsSelected: true
这是我想要实现的目标:
当用户点击某个区域时,系统会提示他/她从加载的JSON文件中提取问题。如果问题的答案是正确的,我需要区域颜色才能更改仅。
到目前为止我的代码:
$(function(){
map = new jvm.Map({
container: $('#map'),
map: 'world_mill_en',//map file
backgroundColor: ['#1E90FF'],//map background color
regionsSelectable:true,//this needs to be true to be able to select a region
onRegionClick: function(event, code){
var map = $('#map').vectorMap('get', 'mapObject');
var regionName = map.getRegionName(code);
$.getJSON('../countries.json', function(data) {
for (var i in data.country) {
if (data.country[i].name === regionName){
var answer = prompt(data.country[i].question, "Type your answer here.");
if(data.country[i].answer === answer){
alert("Correct!");
}else{
alert("Wrong. Try again.");
}
}
}
});
},
});
});
我想我必须找到一种方法,在满足regionsSelectable
条件后动态更改if(data.country[i].answer === answer)
的属性值。如果不是,那么regionsSelectable
的属性值应保持为false
。
我是一名初学者,所以任何批评都非常受欢迎,无论如何,我可能已经离开这里了! :)

试试这个..
$(function(){
map = new jvm.Map({
container: $('#map'),
map: 'world_mill_en',//map file
backgroundColor: ['#1E90FF'],//map background color
regionsSelectable:true,//this needs to be true to be able to select a region
onRegionClick: function(event, code){
var map = $('#map').vectorMap('get', 'mapObject');
var regionName = map.getRegionName(code);
$.getJSON('../countries.json', function(data) {
for (var i in data.country) {
if (data.country[i].name === regionName){
var answer = prompt(data.country[i].question, "Type your answer here.");
if(data.country[i].answer === answer){
map.setSelectedRegions(code);;
}else{
map.clearSelectedRegions();
}
}
}
});
},
});
});
