一、主要运用element封装的控件并封装成组件运用,如图所示
代码如图所示:
下面是子组件的代码:
- {{ item.name }}
*{ box-sizing: border-box; margin: 0;padding: 0; } *:before,*:after{ box-sizing: border-box; } ul, li { list-style: none; } .current{ color: #e9c309 !important } .l_tree_container { width: 100%; height: 100%; box-shadow: 0 0 3px #ccc; margin: 13px; position: relative; } .l_tree { width: calc(100%); padding-left: 15px; } .l_tree_branch { width: 100%; height: 100%; display: block; padding: 13px; position: relative; } .l_tree_branch .l_tree_children_btn { width: 12px; height: 12px; background-color: #515a68; font-size: 8px; text-align: center; color: #bbbec1; outline: none; border: 0; cursor: pointer; border: 1px solid #bbbec1; line-height: 11px; margin-left: 5px; } ul.l_tree:before { content: ''; border-left: 1px dashed #999999; height: calc(100% - 24px); position: absolute; left: 10px; top: 0px; } .l_tree, .l_tree_branch { position: relative; } .l_tree_branch::after { content: ''; width: 18px; height: 0; border-bottom: 1px dashed #bbbec1; position: absolute; right: calc(100% - 10px); top: 24px; left: -5px; } .l_tree_container>.l_tree::before, .l_tree_container>.l_tree>.l_tree_branch::after { display: none; } .l_folder { font-size:11px; margin-left: 5px; display: inline; color: #bbbec1; cursor: pointer; }
主要难点是:current传值问题,所以current绑定在父组件
父组件中的值和方法:
当然在运行npm时是需要安装npm install ewtree -S,实现组件化
最终效果如下:
