Question

我试图使文本显示为与复选框内联并取决于边栏的宽度的块。

示例

我已将代码粘贴到CodePen上（请牢记屏幕分辨率/宽度等），我尝试了多次尝试，甚至从更改为，以及使用“向左浮动”插入行内样式。要从更改为，可以在javascript中“此”下进行。

Answer 1

一种方法可能是在节点包装中添加一些填充，并在复选框内容上以负边距进行调整。我在外部div（.tree-node-adjusted）中添加了一个包装器（.tree-node-adjusted-wrapper）和一个类。这种方法有点破烂，可以计算px偏移量（ems或其他方式），也可以从字体大小中得出px偏移量。

模板

  this.tpl = `
  <div title="{{trvw.label(node)}}" class="tree-node-adjusted" >  
    <div class="tree-node-adjusted-wrapper">
    <span ivh-treeview-toggle >
      <span ivh-treeview-twistie>
      </span>
    </span>
    <span ng-if="trvw.useCheckboxes()" ivh-treeview-checkbox  >
    </span>
    <span class="ivh-treeview-node-label" ivh-treeview-toggle   >
    {{trvw.label(node)}}
    </span>
    </div>
    <div ivh-treeview-children></div>
  </div>`

CSS（在我的Codepen示例中为LESS）：

.ivh-treeview .tree-node-adjusted {

  .tree-node-adjusted-wrapper {
    padding-left: 40px;

    & > span:nth-child(1) {
      margin-left: -40px;
    }
  }
}

See example in Codepen

（另一种解决方案是用一些左填充使节点相对位置，并绝对定位复选框，这可能更精确）。

尝试使用display:flex将曲折的，复选框和标签包装在容器中，并将ivh-treeview-children指令保留为该容器的兄弟。

更新的代码笔：https://codepen.io/jtrussell/pen/qzQNdm?editors=0010

更新的节点模板代码段：

<div title="{{trvw.label(node)}}">       
  <div style="display:flex">
    <span ivh-treeview-toggle >
      <span ivh-treeview-twistie>
      </span>
    </span>
    <span ng-if="trvw.useCheckboxes()" ivh-treeview-checkbox  >
    </span>
    <span class="ivh-treeview-node-label" ivh-treeview-toggle>
    {{trvw.label(node)}}
    </span>
  </div>
  <div ivh-treeview-children></div>
</div>

结果截图：

使用<span>或<div>的HTML / CSS复选框文本对齐
