vue-echarts /div动态的计算高度

Posted 2023-03-01

参考技术A DIV部分

<chart

  ref="taskChart"

  :theme="charts.theme"

  autoresize :options="charts.optionsu"

  @click="zydwclick"

  :style="width:charts.width,height:charts.height">

</chart>

<iframe width="100%" ref="mapIframe" class="rectCorner" id="zykhMapIframe" scrolling="no"

        :src="YZKH_URL" :height="ifram_height"

        frameborder="0">

</iframe>

data部分

charts:

//div的高度

ifram_height:0,

//echarts的高度宽度

width:'100%',

height:"230px",

//自动设置chart的高度

methods:

RowResize()

let me =this;

  const deviceHeight = document.documentElement.clientHeight

  const chartHeight = (Number(deviceHeight) *0.82) /2//两个row

//计算echarts 的高度

  me.charts.height = chartHeight +'px';

//计算div部分的高度

  me.ifram_height = (Number(deviceHeight) *0.78) +'px'

,

在mountd里面调用

mounted()

let me =this;

me.RowResize();

//监视窗口发生变化再调用一次

window.onresize =function ()

me.RowResize();



获取DOM的高度宽度公式

DOM可视高度/DOM最长的高度=计算比例

计算  table高度 

<Table border

      @on-sort-change="onSortChange"

      :columns="tableA.tableColumns"

      :data="tableA.tableData"

      :height="height"

      ref="currentRowTable"

      :percent="percent"

      style="white-space: nowrap;word-break: keep-all"

></Table>

data()

return

height:100,

//自动设置列表的高度

RowResize()

let me =this;

  const deviceHeight = document.documentElement.clientHeight

  if (me.$refs.currentRowTable)

me.height = Number(deviceHeight) *0.65

 

,

let me =this

me.RowResize();

//监听窗口大小变化

window.onresize =function ()

me.RowResize();
