通过 jQuery 从 SVG 中的 PATH 获取 FILL 属性

Question

当我点击 SVG 时，我想从这个 SVG 中获取所有路径的列表。然后从每个 PATH 获取 FILL。但似乎 jquery 不知道属性 FILL.

jQuery

$("#element1").click(function () {
    $('#element1').children('svg').children('path').each(function () {
        alert(this.attr('fill'));
    });
});

Answer 1

您的问题是，jQuery 的 each()-回调获取对 DOM 元素的引用，而不是相应的 jQuery 对象。

所以这对我有用：

$('#element1').children('svg').children('path').each(function () {
    alert( $(this).attr('fill') );
});
