<template>
  <div class="newcom-wrap">
    <el-table ref="multipleTable"
		:data="newComList.list"
		tooltip-effect="dark"
		@selection-change="handleSelectionChange"
        :row-key="getRowKey"
        empty-text="数据正在加载……">
        <el-table-column
	        type="selection"
	        width="55" :reserve-selection="true">
        </el-table-column>
    </el-table>
   </div>
</template>
<script>
export default{
    data(){
        return {
            getNewComForm:{
    		    dataSource:0,
    		    listId:'',
    		    entId:[]
    	    }
        }
    },
    methods: {
        getRowKey(row){
          return row.id
        },
        handleSelectionChange(val) {//监听selection选择事件
    	    this.getNewComForm.entId = []
    	    for(let i in val){//去重以免发生意外的push
    		    if(!this.getNewComForm.entId.includes(val[i].id)){
    			    this.getNewComForm.entId.push(val[i].id)
    		    }  		
    	    }
        }
    }
