SVG＆LT;使用＆GT;在Chrome中不工作 [英] SVG <use> in Chrome doesn't work

问题描述

有是SAP（AngularJS和角度线）与SVG-精灵制作基于图标的导航。所以，我哈瓦直列code是这样的：

There is SAP (AngularJS and Angular Route) with icon-based navigation made by svg-sprite. So, I hava inline code like this:

<div style="height: 0; width: 0; position: absolute; visibility: hidden">
<svg xmlns="http://www.w3.org/2000/svg">
    <symbol id="icon-grid-32" viewBox="0 0 32 32">
        <g stroke-width="2" stroke-linecap="round" stroke-miterlimit="10" stroke-linejoin="round">
            <path d="M2 2h11v11H2zM19 2h11v11H19zM2 19h11v11H2zM19 19h11v11H19z"/>
        </g>
    </symbol>
</svg>
</div>

和导航的图标是这样的：

And the icons in navigation like this:

<a href=""><svg class="icon icon-32 outline black"><use xlink:href="#icon-grid-32"></use></svg></a>

所有我可以在此导航看到的是什么，＆LT;使用＆GT; 的大小为0×0像素。我知道Firefox的错误使用XML：基地，但添加的xml：基础没' ŧ帮助我。你可以试试这个例子：的http：// CSS .yoksel.ru /资产/演示/ SVG-在火狐/ SVG-HAS-base.html文件

All that I can see in this navigation is nothing, <use> has size 0 × 0 pixels. I know about Firefox bug with xml:base, but adding xml:base didn't help me. You can try this example: http://css.yoksel.ru/assets/demo/svg-in-firefox/svg-has-base.html

它工作在Firefox，Safari和其他浏览器，但无法在Chrome 49+（48版本没有这个问题）。

It works in Firefox, Safari and other browsers but not in Chrome 49+ (48 version doesn't have this problem).

推荐答案

我正经历真的类似的问题，给你一个不同的描述一下，我会产生我的图标＆LT; SVG＆GT; 和＆LT;使用方式＆gt;在指令

I was experiencing really similar issue to what you describe with a difference that I would generate my icons <svg> and <use> in a directive.

我一直在寻找今天的大部分时间的答案，并想出了一个变通的＆LT;使用＆GT; 和的xlink： HREF 的问题。它只需通过内联通缉SVG再现的功能。

I have been looking for an answer for a better part of today and came up with a workaround to the <use> and xlink:href question. Which simply recreates the functionality by inlining the wanted svg.

为了简单起见，假设我有＆LT;角图标＆GT;通过属性接收图标的名称指令 icon-名称

For the sake of simplicity let's say i have <angular-icon> directive that receives the name of the icon by an attribute icon-name

＆LT;角图标图标名称={{someObject.iconName}}＆GT;

工作指令现在看起来如下：

working directive now looks as follows:

angular.module('angularIcon', [])
.directive('angularIcon', IconDirective);

function IconDirective(){
    return{
        template:'',
        templateNamespace:'svg',

        link:function(scope, element, attributes){

            // my icon name comes from $http call so it doesnt exist when initialising the directive, 
            attributes.$observe( 'iconName', function(iconName){

                // let's grab the icon from the sprite
                var icon = angular.element( document.getElementById( iconName ) ); 
                // let's clone it so we can modify it if we want
                var iconClone = icon.clone();

                var namespace = "http://www.w3.org/2000/svg";

                // manually create the svg element and append the inlined icon as no other way worked
                var svg = document.createElementNS( namespace, 'svg' );
                svg.setAttribute( 'viewBox', '0 0 32 32' );
                svg.setAttribute( 'xml:space', 'preserve' );

                svg.appendChild( iconClone[0] );
                // let's add the newly created svg+icon to the directive's element
                element[0].appendChild( svg );

            });

        },
        scope:{
            iconName: '@'
        }
    }
}
