我的问题是我从数据库中收到一堆完整的内联svg字符串，如下所示：

现在我想使用此模板将它们全部添加到容器中：

我想更改svg的整个大小，内容应按比例缩放，以便适合容器。

如何通过Javascript / JQuery或CSS执行此操作？

这是我使用的模板的html：

 <script type="text/template" id="previewGallerytmpl">

            <% for (var i = 0; i < svgList.length; i++) { %>

             <% var svg = svgList[i]; 
                var string = svg.svgString;
                console.log(string);
                    %>  

                        <div class="content-to-scale">
                          <%= string  %>


                        <%= svg.sketchErsteller %>
                        </div>
            <%
            }
            %>

    </script>

谢谢;）

Answer 1

还有一个跨浏览器的解决方案，可以让浏览器为您扩展SVG。但是，它要求您的SVG具有有效的viewBox属性。例如：

viewBox="0 0 640 480"

然后使用CSS宽度和高度来调整SVG的大小。它甚至可以在指定的框中自动缩放和居中SVG。

您没有说出您的SVG文件来自何处，因此我不知道您是否可以依赖具有viewBox的文件。您的示例没有，但是，例如，如果您的所有文件同样由svg-edit生成，您可以在将它们保存到数据库或从中拉出它时自动添加视图。

无论如何，在这里演示：http://jsfiddle.net/VddWR/

Answer 2

通过添加：

解决

svg g {
    -webkit-transform: scale(0.5);
}

到css文件。

使用CSS缩放所有svg元素
