需求分析

使用自定义组件进行场景搭建首先需要以下几点:

  • 跟客户进行深入的讨论和研究，确定客户的需求。
  • 通过手绘或者电脑绘制出大致的样式，继续跟客户确定是否可行。
  • 通过美术组对之前绘制的图形进行美化、加工和配色。
  • 拿到美术组绘制的图片后，确定下实施的方案。
  • 确定数据格式。 ===> (非常重要,如果数据不对极易出现双方返工的现象)
  • 通过 JavaScript 脚本来实现。

由于已经确定好客户的需求，以及通过美术组的设计，所以直接上需求图。

实施方案

选择组件

首先在编辑模式下从通用里面拖拽出一个空白组件

定义数据格式

定义数据格式分为两步

  • 确定数据格式

  • 将数据 “放” 到组件中

确定数据格式

放入数据

代码开发

首先通过双击的形式打开组件控制中心,进行 JavaScript 脚本的编写

PS: 如果宽度不够可以通过拖拽的形式增加宽度

编写代码如下所示

this.clearDom()  //在每次进入创建DOM之前必须清除之前的DOM
let dom = this.getDom() //获取DOM节点
let jq = this.getJquery() //获取Jquery
let data = this.getComponentData() //获取组件数据

let topTitle = data.topTitle //标签数据
let title = data.title  //标题数据
let content = data.content  //内容数据

let backgroundStyle = {  //整个面板的样式
    borderColor:'skyblue' //面板的边框色
}
let topTitleStyle = { //标签整体样式
    width:'100%',
    height:'50px',
    borderBottom:'1px solid #646464'
}
let titleStyle = { //标题整体样式
    width:'100%',
    height:'50px'
}
let contentStyle = { //内容整体样式
    width:'100%',
    height:'calc(100% - 100px)'
}
jq(dom).css(backgroundStyle) //将面板样式给面板
jq(dom).append('<div></div><div></div><div></div>') //创建标签、标题和内容的div
let domChildren = jq(dom).children() //获取到刚才创建的标签
jq(domChildren[0]).css(topTitleStyle) //赋予标签样式
jq(domChildren[1]).css(titleStyle)  //赋予标题样式
jq(domChildren[2]).css(contentStyle)  //赋予内容样式

let topTitleLength = topTitle.length //通过标签数据进行循环
for(let i = 0 ; i < topTitleLength ; i += 1) {
    let divStyle = `width:${topTitle[i].topTitleWidth};height:100%;text-align:center;float:left;line-height:50px;font-size:18px;border-right:1px solid #646464`
    if(i === topTitleLength -1) { //当是最后一条时，不添加边框
divStyle =`width:${topTitle[i].topTitleWidth};height:100%;text-align:center;float:left;line-height:50px;font-size:18px;` 
    }
    let topTitleDiv = `<div style="${divStyle}">${topTitle[i].topTitleName}</div>`
    let otherDiv = `<div style="${divStyle}"></div>`
    jq(domChildren[0]).append(topTitleDiv) //创建标签的div
    jq(domChildren[1]).append(otherDiv) //通过标签的宽来规划下面内容的宽
    jq(domChildren[2]).append(otherDiv)
}
let topTitleDom = jq(domChildren[0]).children() //获取到标签DOM
let titleDom = jq(domChildren[1]).children()  //获取标题DOM
let contentDom = jq(domChildren[2]).children()  //获取内容DOM
for(let i = 0 ; i < topTitleLength ; i += 1) {
    let titleData = title[jq(topTitleDom[i]).text()] //通过标签内容获取到标题的数据
    if(titleData) { //由于标题的第一格是空的所以要进行判断
let titleLength = titleData.length
for(let j = 0 ; j < titleLength ; j += 1) {
let divStyle = `width:${titleData[j].titleWidth};height:100%;text-align:center;float:left;line-height:50px;font-size:18px;border-right:1px solid #646464`
if(j === titleLength-1) {
    divStyle = `width:${titleData[j].titleWidth};height:100%;text-align:center;float:left;line-height:50px;font-size:18px`
}
let titleDiv = `<div style="${divStyle}">${titleData[j].titleName}</div>` //创建标题DOM 
let contentDiv = `<div style="${divStyle}"></div>` //通过标题的宽来规划下面内容的宽

jq(titleDom[i]).append(titleDiv) 
jq(contentDom[i]).append(contentDiv)
}
    }
}
let contentArr = Object.keys(content) //获取到内容的key
let contentArrLength = contentArr.length
for(let i = 0 ; i < contentArrLength ; i += 1) { //循环每一条数据
    let contentStatusList = content[contentArr[i]]
    let titleNameDiv = `<div style="width:100%;height:50px;border-top:1px solid #646464;">${contentArr[i]}</div>`
    jq(contentDom[0]).append(titleNameDiv)
    let titleLength = topTitle.length
    for(let j = 0 ; j < titleLength ; j += 1) { 
let contentNameDomArr = jq(titleDom[j]).children()
let contentNameDomList = jq(contentDom[j]).children()
let contentNameDomLength = contentNameDomArr.length
for(let z = 0 ; z < contentNameDomLength ; z += 1) {
let contentName = jq(contentNameDomArr[z]).text()
let status = contentStatusList[contentName].status
let divColor='' //根据状态来判定内容显示的颜色
if(status === 1) {
    divColor='color:#42F843;'
}
if(status === 2) {
    divColor='color:#228BFE;'
}
if(status === 3) {
    divColor='color:#F8D442;'
}
if(status === 4) {
    divColor='color:#F57027;'
}
if(status === 5) {
    divColor='color:#FA4C4A;'
}
let contentNameDomDiv = `<div style="width:100%;height:50px;border-top:1px solid #646464;font-size:40px;${divColor}">●</div>`
jq(contentNameDomList[z]).append(contentNameDomDiv) //创建内容DOM
}
    }
}
