AngularJS ng-href和svg xlink [英] AngularJS ng-href and svg xlink

问题描述

我想要一些有关将XML命名空间属性与angular一起使用的信息.

I'd like some input on using xml namespaced attributes with angular.

问题是angular附带了一些指令，用于在angular分析了表达式后处理诸如href和src之类的书写属性(否则浏览器将尝试将{{mymodel.myimage}}加载为url)

The problem is angular comes with a couple of directives to handle writing attributes such as href and src when angular has parsed the expresssions (otherwise the browser will try to load {{mymodel.myimage}} as a url)

https://github.com. com/angular/angular.js/blob/master/src/ng/directive/booleanAttrs.js#L329

我面临的问题是我正在使用angular来与D3一起输出svg，并且由于angular没有办法输出xlink:href，所以我被卡住了.

The problem I'm facing is that I'm using angular to output svg together with D3 and since angular doesn't have a way to output xlink:href I was stuck.

我创建了一个自定义指令，该指令输出xlink:href

I created a custom directive that outputs xlink:href

app.directive('ngXlinkHref', function () {
  return {
    priority: 99,
    restrict: 'A',
    link: function (scope, element, attr) {
      var attrName = 'xlink:href';
      attr.$observe('ngXlinkHref', function (value) {
        if (!value)
          return;

        attr.$set(attrName, value);
      });
    }
  };
});

但是，如果我不手动将xlink:href添加到元素，则svg图像将无法呈现.

But it seems that if I don't manually add xlink:href to the element, the svg image will not render.

任何有关如何最好地与xml一起处理xml名称空间/svg的建议将不胜感激.

Any suggestions on how to best handle xml namespaces / svg together with angular would be greatly appreciated.

推荐答案

您可以使用ng-attr-<some attribute>

ng-attr-xlink:href="{{xxx}}"为我工作.

请注意，您还需要一个空的xlink:href=""作为初始值. –徐熙re

Note that you also need an empty xlink:href="" as initial value. – Derek Hsu
