# 业务关系图JS连线组件

#### 项目介绍
纯div+css3实现模拟画线条功能，用于前端业务关系图绘制的连线组件

#### 软件架构
软件架构说明
使用前端模板引擎 artTemplate,
jquery,
数学计算方程库algebra 
div+css3实现
轻量级的纯div连线组件

#### 安装教程
###
1、引入 css: third/shape/shape.css

2. 引入jquery:  third/jquery/jquery-2.1.4.min.js 

3、引入artTemplate： third/template/template_debug_3_0_0.js

4、引入 algebra 数学公式计算库:third/algebra/algebra-0.2.5.min.js

5、引入画线图形组件库:third/shape_min/shape.min.js

#### 使用说明
1. 承载线条和div层的容器样式代码参考
###
        .paper-area {
            background-color: #ffffff;
            z-index: 1;
            position: relative;
            margin: 30px auto;
            overflow: hidden;
            display: block;
            box-shadow: rgba(0, 0, 0, 0.31) 0 0 13px;
        }
        .paper-area .paper-area{
            background-color: transparent;
            margin: 0 auto;
            z-index: 0;
        }
###

2. div层代码参考
 
        .control-abs-component{
            background-color: rgba(255,255,255,.7);
            width: 140px;
            height: 42px;
            padding: 5px;
            font-size: 0;
            display: block;
            border: 1px solid transparent;
            position: absolute;
            left: 0;
            top: 0;
            z-index: 1;
            -webkit-user-select: none;
            -moz-user-select: none;
            -ms-user-select: none;
            user-select: none;
        }
###
3、线条自定义样式参考
 .ours-line-text .text-color{
     color: #ffffff;
 }
###
4、body内html代码 参考
