vue+element-ui表格最大高度适配解决方案

第一步：utils目录下创建一个文件为directive，新建auto-height.js文件，

  1. export default {
  2.   componentUpdated(el, binding, vnode) {
  3.       const ctx = vnode.context;
  5.       if (!ctx || typeof ctx[binding.arg] === 'undefined' || ctx.autoHeightResizeListenner) return;
  9.       ctx.autoHeightResizeListenner = () => {
  10.           let top = el.offsetTop;
  12.           let cur = el.offsetParent;
  14.           while(cur !== null) {
  15.           top += cur.offsetTop;
  17.           cur = cur.offsetParent;
  19.         }
  21.         const h = (window.innerHeight - top) + binding.value;
  23.         ctx[binding.arg] = Math.max(h, 100 );
  25.       };
  27.       window.addEventListener('resize', ctx.autoHeightResizeListener, false);
  29.       setTimeout(ctx.autoHeightResizeListenner, 50);
  31.     },
  33.     unbind(el, binding, vnode){
  34.       const ctx = vnode.context;
  36.       if(ctx && ctx.autoHeightResizeListener) {
  38.       window.removeEventListener('resize', ctx.autoHeightResizeListener, false);
  40.       ctx.autoHeightResizeListener = null;
  42.     }
  44.   },
  46. };

第二步：全局配置 在main.js中导入 auto-height.js文件

  1. import autoHeight from './utils/directive/auto-height';
  3. Vue.directive('auto-height',autoHeight)

第三步：组件中需要的标签添加两个属性 v-auto-height:maxHeight = ‘-10’ :max-height=”maxHeight”

  1. <el-table   v-auto-height:maxHeight = '-10' :max-height="maxHeight"></el-table>
