這里有三點需要說明:
1. 使用:before-close="closeHandle" 將其 $emit() 出去
2. 取消按鈕 也需要$emeit出去
3. 控制對話框顯示隱藏的變量需要props給父組件來傳值,這個相當重要,不然控制不了對話框的顯示隱藏
4.1,2步驟是為了在子組件不再重復操作顯示隱藏的變量,vue會報錯
現在看代碼:
對話框子組件:
<el-dialog :title="dialogTitle" :visible.sync="createDialog" width="544px" center custom-class="dialogStyle" :before-close="handleClose"> <el-form ref="pushForm" label-position="right" :model="pushForm" :rules="Rules" label-width="100px"> <el-form-item label="URL" prop="url"> <el-input placeholder="請輸入URL鏈接" clearable v-model="pushForm.url"></el-input> </el-form-item> <el-form-item label="備注" prop="depicts"> <el-input type="textarea" :rows="4" placeholder="請輸入備注內容(255字符以內)" v-model="pushForm.depicts" maxlength="255"> </el-input> </el-form-item> <el-form-item label="是否啟用" prop="isEnable"> <el-radio-group v-model="pushForm.isEnable"> <el-radio :label="0">啟用</el-radio> <el-radio :label="1">禁用</el-radio> </el-radio-group> </el-form-item> </el-form> <div slot="footer" class="dialog-footer"> <el-button @click="handleClose">取 消</el-button> <el-button type="primary" @click="submitPushForm">確 定</el-button> </div> </el-dialog> export default { name: '', props: { title: { type: String, default: '' }, createDialog: { type: Boolean } // pushDataList: { // type: Array, // // default: [] // } }, .... methods: { addDialog (sign, item) { // this.createDialog = true this.$emit('opendialog') this.dialogTitle = sign + this.title this.typeNum = item.type this.reMark = sign }, editDialog (sign, item) { // this.createDialog = true this.$emit('opendialog') this.dialogTitle = sign + this.title this.typeNum = item.type this.reMark = sign }, submitPushForm () { this.$refs.pushForm.validate((valid) => { if (valid) { console.log(this.pushForm) this.pushForm.type = this.typeNum if (this.reMark === '添加') { this.$emit('addPushHandle', this.pushForm) } else if (this.reMark === '編輯') { this.$emit('updatePushHandle', this.pushForm) } } else { console.log('error submit!') } }) }, handleClose () { this.$emit('closeDialog') // 取消和 x 按鈕的事件,防止重復操作createDialog變量
}, }
父組件:
<push-data :title="title" :createDialog="createDialog" @opendialog="opendialog" @addPushHandle="addPushHandle" @updatePushHandle="updatePushHandle" @closeDialog="closeHandle"></push-data> data () { return { title: '應用推送', createDialog: false } }, methods: { opendialog () { this.createDialog = true }, addPushHandle (form) { // console.log('添加應用推送') // console.log(form) // console.log(this.applicationId) let params = Object.assign({},form,{applicationId: this.applicationId}) console.log(params) this.createDialog = false // 親測。操作dialog可以生效 }, updatePushHandle (form) { console.log('編輯應用推送') applicationPushUpdate().then((res) => { }).catch((err) => { }) }, closeHandle () { this.createDialog = false // 控制取消和X按鈕,關閉彈窗 }
以上就是個人總結,如果小伙伴有更好的方法,歡迎留言交流哦!!!^_^
