el-dialog body滾動的設置

　　 .el-dialog {
      position: relative;
      margin: 0 auto 0px;
      background: #FFFFFF;
      border-radius: 2px;
      -webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.3);
      box-shadow: 0 1px 3px rgba(0, 0, 0, 0.3);
      -webkit-box-sizing: border-box;
      box-sizing: border-box;
      width: 50%;
      height: 60%;
    }
    .el-dialog__body {
      border-top: 1px solid #dcdfe6;
      border-bottom: 1px solid #dcdfe6;
      max-height:85%  !important;
      min-height: 70%;
      overflow-y: auto;
      //如需設置滾動條樣式
      &::-webkit-scrollbar {
        width: 2px;
        background-color: #ccc;
      }
      &::-webkit-scrollbar-thumb {
        background-color: #0ae;
      }
      &::-webkit-scrollbar-track {
        background-color: #ccc;
      }
    }

 

 或者

 

.el-dialog {
    margin: 4% auto auto auto !important;
    height: 500px;
    .el-dialog__body {
      position: absolute;
      left: 0;
      top: 54px;
      bottom: 0;
      right: 0;
      padding: 0;
      z-index: 1;
      overflow: hidden;
      overflow-y: auto;
      box-sizing: border-box;
　　　　
      &::-webkit-scrollbar {
        width: 2px;
        background-color: #ccc;
      }
      &::-webkit-scrollbar-thumb {
        background-color: #0ae;
      }
      &::-webkit-scrollbar-track {
        background-color: #ccc;
      }
    }
  }

 

 或者極簡模式：

.el-dialog {
    .el-dialog__body {
      //border-top: 1px solid #dcdfe6;
      //border-bottom: 1px solid #dcdfe6;
      max-height: 500px !important;
      min-height: 100px;
      overflow-y: auto;
    }
  }
