Twitter Bootstrap 中的树 [英] Trees in Twitter Bootstrap

问题描述

我一直在尝试创建一棵树(如目录树)，它使用尽可能多的 CSS 和尽可能少的 JS(仅用于状态等)，我想知道是否有一些好的现有树添加到 Bootstrap.请参阅 http://jhfrench.github.io/bootstrap-tree 上的项目文档/docs/example.html.

或者，这里是生成该 CSS 的 LESS 源(可以从 jsFiddle):

@import "../../../external/bootstrap/less/bootstrap.less";/* 替换你的 bootstrap.less 文件路径 */@import "../../../external/bootstrap/less/responsive.less";/* 可选的;替换你的responsive.less 文件的路径*//* 可折叠的树 */.树 {.border-radius(@baseBorderRadius);.box-shadow(inset 0 1px 1px rgba(0,0,0,.05));背景色:变亮(@grayLighter，5%)；边框:1px 实心@grayLight；底边距:10px；最大高度:300px；最小高度:20px；溢出-y:自动；填充:19px；一种 {显示:块；溢出:隐藏；文本溢出:省略号；宽度:90%；}李{列表样式类型:无；边距:0px 0;填充:4px 0px 0px 2px；位置:相对；&::before, &::after {内容: '';左:-20px；位置:绝对；右:自动；}&::before {左边框:1px 实心@grayLight；底部:50px；高度:100%；顶部:0；宽度:1px；}&::after {边框顶部:1px 实心@grayLight；高度:20px；顶部:13px；宽度:23px；}跨度 {-moz-border-radius: 5px;-webkit-border-radius: 5px;边框:1px 实心@grayLight；边框半径:5px；显示:内联块；行高:14px；填充:2px 4px；文字装饰:无；}&.parent_li >跨度 {光标:指针；/*一些悬停效果的时间*/&:hover, &:hover+ul li span {背景:@grayLighter；边框:1px 实心@gray；颜色:#000；}}/*删除最后一个孩子之后的连接器*/&:last-child::before {高度:30px；}}/*删除root之前的连接器*/>升 >里::之前，>升 >里::之后{边框:0；}}

I have been trying to work on creating a tree (like a directory tree) that uses as much CSS and as little JS as possible (only for states, etc), and I want to know if there are some good existing tree plugins for bootstrap or jquery-ui bootstrap.

For reference or for people confused about this question, I am looking for something like dynatree for bootstrap.

解决方案

Building on Vitaliy's CSS and Mehmet's jQuery, I changed the a tags to span tags and incorporated some Glyphicons and badging into my take on a Bootstrap tree widget.

Example:

For extra credit, I've created a GitHub project to host the jQuery and LESS code that goes into adding this tree component to Bootstrap. Please see the project documentation at http://jhfrench.github.io/bootstrap-tree/docs/example.html.

Alternately, here is the LESS source to generate that CSS (the JS can be picked up from the jsFiddle):

@import "../../../external/bootstrap/less/bootstrap.less"; /* substitute your path to the bootstrap.less file */
@import "../../../external/bootstrap/less/responsive.less"; /* optional; substitute your path to the responsive.less file */

/* collapsable tree */
.tree {
    .border-radius(@baseBorderRadius);
    .box-shadow(inset 0 1px 1px rgba(0,0,0,.05));
    background-color: lighten(@grayLighter, 5%);
    border: 1px solid @grayLight;
    margin-bottom: 10px;
    max-height: 300px;
    min-height: 20px;
    overflow-y: auto;
    padding: 19px;
    a {
        display: block;
        overflow: hidden;
        text-overflow: ellipsis;
        width: 90%;
    }
    li {
        list-style-type: none;
        margin: 0px 0;
        padding: 4px 0px 0px 2px;
        position: relative;
        &::before, &::after {
            content: '';
            left: -20px;
            position: absolute;
            right: auto;
        }
        &::before {
            border-left: 1px solid @grayLight;
            bottom: 50px;
            height: 100%;
            top: 0;
            width: 1px;
        }
        &::after {
            border-top: 1px solid @grayLight;
            height: 20px;
            top: 13px;
            width: 23px;
        }
        span {
            -moz-border-radius: 5px;
            -webkit-border-radius: 5px;
            border: 1px solid @grayLight;
            border-radius: 5px;
            display: inline-block;
            line-height: 14px;
            padding: 2px 4px;
            text-decoration: none;
        }
        &.parent_li > span {
            cursor: pointer;
            /*Time for some hover effects*/
            &:hover, &:hover+ul li span {
                background: @grayLighter;
                border: 1px solid @gray;
                color: #000;
            }
        }
        /*Remove connectors after last child*/
        &:last-child::before {
            height: 30px;
        }
    }
    /*Remove connectors before root*/
    > ul > li::before, > ul > li::after {
        border: 0;
    }
}
