在我的研究过程中,我了解到我需要指定我需要使用的(图标),如下所示:

import {faChevronLeft, faChevronRight} from '@fortawesome/fontawesome-free-solid';
import fontawesome from '@fortawesome/fontawesome';
然后我需要将这些图标传递给Fontsome对象:

fontawesome.library.add(faChevronLeft, faChevronRight);
最后,我发现(在中),我需要调用i2svg方法来实现这个神奇的过程:

fontawesome.dom.i2svg();
文档说明我必须调用不带参数的方法。但编译器将我指向另一个方向,我必须通知以下数据:

export interface DOM {
  i2svg(params: { node: Node; callback: () => void }): void;
  css(): string;
  insertCss(): string;
}
到目前为止,我所获得的最大值是font awesome在浏览器中创建的一个日志,其中包含以下信息“fontawesome.dom.i2svg()”:

fontawesome.dom.i2svg({ node: document.body, callback: callbacki2Svr });

function callbacki2Svr() { }
我已经尝试了很多(null导致“uncaughttypeerror:cannotreadproperty'queryselectoral'ofnull”),现在我无法前进。有人有什么建议吗

安装:

1) 按照([TOKEN]是我从购买中收到的密钥)上的说明进行操作:

2) 更新的angular cli 3) 使用(ng b-aot)重新生成应用程序 4) 启动了这个项目

我们正在开发一个官方的角度组件(目前正在预发布中)

然而,@daniel santana告诉我们,这不可能集成到他们的大型应用程序中


所以我能给你的最好建议是不要使用SVG和JS方法。它使用了诸如requestAnimationFrame和MutationObserver之类的高级功能,但这些功能在Angular应用中并不好。如果你无法重构你的应用程序以使用新的SVG格式(这在字体Awesome 5中是新的),那么请坚持使用。版本5的Web字体与版本4中的Web字体一样工作。升级到5将涉及更改任何已重命名图标的名称。我们有详细信息。

您能否共享相关的html模板或组件代码?似乎在fontawesome.dom.i2svg({node:document.body,callback:callbacki2Svr})中用于查找标记的“document.body”为空。这就是为什么它抛出“UncaughtTypeError:无法读取null的属性'querySelectorAll'”尝试添加角度字体。配置如下:@janathanan,按照您的建议添加了代码。只有一点:当我传递null时会发生异常。传递document.body仅在控制台中打印一条消息(“fontawesome.dom.i2svg()”。@SaptarshiBasu,谢谢您的建议。这个软件包使用了font Asome4.7版本,但我计划使用我购买的:5.0。你在哪里指定了你使用的图标?我的意思是,有人告诉我,我需要像你在全局区域中那样将图标添加到库字段中,但我不确定全局区域在项目中的含义。谢谢你,Rob。我认为你的问题是解决问题的问题。
