Question

这里有一个独特的问题，当它用作background image时，不确定如何定位和更改SVG的填充颜色。在我的情况下，点击这个类myGreen交换到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');
});

由Illustrator创建的SVG代码

<?xml version="1.0" encoding="utf-8"?>

 width="15px" height="28px" viewBox="0 0 15 28" enable-background="new 0 0 15 28" xml:space="preserve">

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

Answer 1

创建灰色背景图像文件，然后单击更改背景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.

Answer 2

或者，如果您想在浏览器中执行此操作，请尝试：

var green = '3CB54A';
var red = 'ED1F24';
var svg = '<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"  width="320px" height="100px" viewBox="0 0 320 100" enable-background="new 0 0 320 100" xml:space="preserve"> <polygon class="mystar" fill="#'+green+'" points="134.973,14.204 143.295,31.066 161.903,33.77 148.438,46.896 151.617,65.43 134.973,56.679 118.329,65.43 121.507,46.896 108.042,33.77 126.65,31.066 "/><circle class="mycircle" fill="#'+red+'" cx="202.028" cy="58.342" r="12.26"/></svg>';      
var encoded = window.btoa(svg);
document.body.style.background = "url(data:image/svg+xml;base64,"+encoded+")";
