Question

这里的问题非常独特，当我的 SVG 用作 background image 时，不确定如何定位和更改它的填充颜色.在我的例子中，单击时将类 myGreen 交换为 myGray。

html

<div id="icon_phone">Phone</div>

CSS

#icon_phone {
    padding-left: 15px;
    height: 30px;
    font-family: Arial;
    background: url('http://leongaban.com/_codepen/svg/ico_my_phone.svg') no-repeat;
    background-size:10px 20px;
    cursor: pointer;
}

当前的 jQuery

$("#icon_phone").unbind('click').bind('click', function () {
    //$(this).css('background', 'none');
});

我在这里找到了如何将类添加到 svg 文件中: http://tutorials.jenkov.com/svg/svg-and-css.html

创建一个灰色背景图像文件并单击更改背景 URL 以指向备用图像。

Images cannot be manipulated by the host document. Think of SVG when used as an image as being like a scalable bitmap.
