1.弹出框动态绑定标题:title

		<el-dialog :title="titleMap[dialogStatus]" :visible.sync="dialogFormVisible" :rules="rules" ref="ruleForm">
			<el-form>
				<el-form-item label="角色" :label-width="formLabelWidth" :rules="[{ required: true, message: '输入角色名', trigger: 'blur' }]">
					<el-input v-model="form.roleName" auto-complete="off" style="width: 300px;"></el-input>
				</el-form-item>
			</el-form>
			<div slot="footer" class="dialog-footer">
				<el-button @click="cancel">取 消</el-button>
				<el-button type="primary" @click="update('ruleForm')">确 定</el-button>
			</div>
		</el-dialog>

2.在data中定义

titleMap: {
			addEquipment: '新增角色',   //根据自己内容定义名字
			editEquipment: "编辑角色"   //根据自己内容定义名字
		},
	//新增和编辑弹框标题
	dialogStatus: "",

3.在methods中你新增和编辑的绑定的方法中添加如下

//新增
add() {
				this.dialogStatus = "addEquipment";
				this.dialogFormVisible = true
			},
//编辑

  handleEdit() {
				this.dialogFormVisible = true
				this.dialogStatus = "editEquipment"
			},
