Question

我的tags-modal上有一个ng-style =“tghov.top”，但它没有转换为标记中的style="top:50!important"。

this.top = { "top" : "50px !important" };

  var app = angular.module('plunker', ['ui.bootstrap'])
  .component('tagHover', {
        template: `<section class="tags-modal"
          ng-show="tghov.tag.hoverDisplay"
          ng-style="tghov.top"
          ng-mouseleave="tghov.leave()">
          <h1>Hover for: {{ tghov.tag.term }}</h1>
          Top position: {{ tghov.top }}
        </section>`,
        controller: TagHoverController,
        controllerAs: 'tghov',
        bindings : {
            tag: '<'
        }
      });

  TagHoverController.$inject = [
      '$scope'
  ];

  function TagHoverController(
      $scope) {
        
      this.top = { "top" : "50px !important" };
  }

  app.controller('MainCtrl', function($scope) {
  });

  app.component('myComponent', {
    bindings: {},
    template: `<section class="tags-view">
        <div class="tags-column">
          <h1>Tags</h1>
          <div class="tags-container">
            <ul>
              <li ng-repeat="tag in tgs.tags">
                
                <div class="tag-container-container" ng-mouseleave="tgs.leaveTag(tag)">
                  <div class="tag-container">
                    <div class="tag" ng-mouseover="tgs.tagHover(tag)">{{ tag.term }}</div>
                    <tag-hover tag="tag"></tag-hover>
                  </div>
                </div>
                
              </li>
            </ul>
          </div>
        </div>
        <div class="tags-content">
          <div class="tags-box">
            <h2>Tags Content</h2> 
          </div>
        </div>
      </section>`,
    controllerAs: 'tgs',
    controller: TagsCtrl
  });


  TagsCtrl.$inject = [
      '$scope',
      '$uibModal'];

  function TagsCtrl(
      $scope,
      $uibModal) {
      ///////////////////////////////////
      
      this.hello = "hello world";
      
      this.leaveTag = (tag) => tag.hoverDisplay = false;
      
      this.tagHover = (tag) => tag.hoverDisplay = true;
      
      this.tags = [
        { id:0, term: 'apple'},
        { id:1, term: 'butter'},
        { id:2, term: 'charlie'},

我将!important修改为没有position: "absolute"，并将!important属性添加到您的热门媒体资源，现在似乎可以正常工作。

您无需担心.superview，因为您将添加html标记的style属性，该标记在CSS中具有最高优先级。
