我很快就要拍了(提问者注意)
这是我正在使用的 SVG 图像:http ://en.wikipedia.org/w/index.php?title=File:World98.svg&page=1
这是一个免费的公共领域——用 SVG 制作的全球地图,其中(几乎)每个国家都被各自的边界所包围。
不要去那里!您不必立即寻找它。
我有件事要先告诉你。
这是图像的相关部分:(
编辑)西班牙是我在这两个例子中试图操纵的国家

我想要做的是用 Javascript 用红色填充国家。
我试过这个:
尝试#1 -没有成功
function selectedCountryChanged(id) {
var tmp = $("#selectedCountry").find("option:selected");
var val = tmp.data('alpha');
console.log('val'); // shows ESP in console
for (var s in a.style) {
console.log(s); // shows correctly all style properties in console
}
var a = document.getElementById("g"+val);
a.style.fill = '#ffff00';
console.log(a.style.fill); // shows rgb(255, 0, 0) in console
}
尝试#2 -没有成功
function selectedCountryChanged(id) {
var tmp = $("#selectedCountry").find("option:selected");
var val = tmp.data('alpha');
var a = document.getElementById("g"+val);
console.log(val); // shows ESP in console
for(var s in a.style) {
console.log(s); // shows all css-properties correctly
}
console.log(id + " " + val);
a.setAttribute("style", "fill: #ff0000");
console.log(a.style.getPropertyValue("fill")); // shows rgb(255, 0, 0) in console
}
即使所有的调试信息都显示一切正常,这该死的东西为什么没有用红色填充一定是有原因的?如果我通过在 SVG 文件中分叉 css-part 手动执行此操作,则显示正常。
我只包含了代码中最相关的部分(恕我直言)。我会根据要求发布更多信息。
编辑:使用 Google Chrome 和 Mozilla Firefox 测试。两者都失败了。
编辑#2:在这两种方法中,Firebug 和 Javascript 控制台(在 Chrome 中)都没有出错。

@Bill 在他的评论中和@Simon Boudrias 在他的回答中都指出了问题所在。
主元素的许多子路径都填充了白色,需要被覆盖。解决方案终于是微不足道的。
解决方案
function selectedCountryChanged(id) {
// use the selection id to get alpha3-country identifier
var tmp = $("#selectedCountry").find("option:selected");
var val = tmp.data('alpha');
// Get the style - element defined in SVG
var a = document.getElementById("mapStyle");
// By assigning the * as class name, we quarantee
// that all the children are filled with red as well
var newFill = "#g"+val+" * { fill: red; }";
// If prevSelectedCountry is set, remove the red filling by
// setting it white
if (window.prevSelectedCountry != undefined) {
$(a).append(window.prevSelectedCountry);
}
// Add this country to prevSelectedCountry
window.prevSelectedCountry = "#g"+val+" * { fill: white; }";
// Fill this country with red
$(a).append(newFill);
}
