遇到了這個解決了，所以記錄一下：

完成vue.js下拉框選擇繫結與取值，實現效果圖如下：

template程式碼

<template>

    <div>
        <Form :model="formItem" ref="formItem" :rules="ruleInline" :label-width="80">

      

            <FormItem label="完成狀態 : " prop="sendValue">
                <Select style="width:200px" v-model="formItem.sendValue">
                    <Option v-for="item in formItem.stateList" :value="item.value" :key="item.value" name="sendValue">{{
                        item.label }}
                    </Option>
                </Select>
            </FormItem>
        
        </Form>
    </div>


</template>
 

js程式碼

<script type="text/ecmascript-6">
    export default {
        mounted() {
            this.getData();

                                that.$Message.error(res.data.result);
                            }


                        });

                    }

                        },

                            label: '停用'
                        },

                            value: '4',

                        }
                    ]
                
            

        }
    }
</script>
 

上述程式碼中this.formItem.sendValue獲取我們最終選中的值，可以做其他的操作了。
