Answer 1

检查 FIDDLE 上更新的代码。已对 SVG 标签进行更改，并将 data-index 属性应用于圆圈和按钮。如果选定的圆圈 dta-index 属性与单击的按钮 data-index 属性相同，那么它将应用颜色，否则显示警报。

var clickedPath = '';
var rIndex = '';
$('#select1,#select2,#select3').on("click", function() {
    clickedPath = $(this);
    rIndex = $(this).attr('data-index');
    clickedPath.css({ stroke: "#00ff00" });
});
		
$('.btn').on('click',function(){
    var attr = '';
    attr = $(this).attr('data-index').split(',');
    if($.inArray(rIndex,attr) >= 0 ){
      clickedPath.css({ fill: $(this).attr('data-color') });
    }else{
      alert("Wrong click");
    }
});
