在選定的SVG中添加屬性 <object> 觸發mouseenter時標記

Question

我正在處理其中包含SVG文件的對象元素。 這是一張地圖。 每個路徑都有相同的默認顏色，但是當mouseenter觸發時，我想用相同的顏色值更改它，但是我不想為所有城市手動設置顏色。 如何動態地做到這一點？

我假設所有“城市”都具有類似於path-number-link ID

重新閱讀問題-忽略：D之前的“樣式”建議

var haritasvg = document.getElementById('haritasvg');
haritasvg.addEventListener("load",function() {
    var svgDoc = haritasvg.contentDocument;
    var pathCatalca = svgDoc.getElementById('pathCatalca');

    var mouser = (function() {
        var saveOldFill = {};
        return function (e) {
            var fill;
            if (e.target && e.target.id && /^path-\d+-link$/.test(e.target.id)) {
                if (e.type == 'mouseenter') {
                    saveOldFill[e.target.id] = e.target.fill;
                    fill = 'url(#redGradient)';
                    e.style.cursor = 'pointer';
                }
                else {
                    fill = saveOldFill[e.target.id];
                }
                e.target.fill = fill;
            }
        }
    }());
    svgElement.addEventListener('mouseenter', mouser);
    svgElement.addEventListener('mouseleave', mouser);
});
