此组件只针对有输入框,然后点击确定进行网络请求,伴随菊花转,请求返回的时候在现实请求结果的,如上图显示
和直接显示菊花转,然后显示网络请求结果的。很简单直接上代码。import React from 'react';import { View, Text, ActivityIndicator, TextInput, TouchableOpacity, Modal,} from 'react-native';import Const from '../../util/const';import System_styles from '../../util/system_styles';import { Button,} from '../../common';export default class AlertView_NetRequest extends React.Component { /** * 组件介绍:本组件只针对直接有网络请求过程和结果显示的情况,和有输入再进行 * 网络请求过程 然后显示结果的情况 * 组件显示:菊花转----- 请求结果 & 输入框 确定 ------ 菊花转-----请求结果 * */ static defaultProps = { firstItem:{ title:'', subTitle:'', cancleBtn:undefined, confirmBtn:'确定', unit:'',输入框的单位 placeHolder:'',///占位符 }, secondItem:{ title:'', subTitle:'', cancleBtn:undefined, confirmBtn:'查看详情', }, firstConfirmBtnClicked:undefined, secondConfirmBtnClicked:undefined, top:140, type:0,///默认直接请求 }; constructor(){ super(); this.state = { text:'', visible:false, step:0,///请求步骤 }; } ///显示 show = ()=>{ this.setState({ step:0, visible:true }) }; ///隐藏 _hide = ()=>{ this.setState({ visible:false, }) }; showNetResult = ()=>{ const {step} = this.state; this.setState({ step:step+1, }) }; ///确定按钮点击 _confirmBtnClicked = ()=>{ const {firstItem,secondItem,type,firstConfirmBtnClicked,secondConfirmBtnClicked} = this.props; const {step}= this.state; var btnClicked = type == 0 ? secondConfirmBtnClicked : (step == 0 ? firstConfirmBtnClicked : secondConfirmBtnClicked); btnClicked&&btnClicked(this.state.text); if(type == 0){ this._hide(); }else { if(step == 0){ this.setState({ step:step+1, }) }else { this._hide(); } } } render() { const {firstItem,secondItem,type} = this.props; const {visible,step}= this.state; var item = type == 0 ? secondItem : (step == 0 ? firstItem : secondItem); let cancleBtnView = item.cancleBtn == undefined ? null : ( ); let bottomBtns = ({cancleBtnView} ); let textInput = type == 0 ? null :( step == 0 ? ():null); let normalContent = (type == 0&&step == 0)||(type == 1 && step == 1) ? ( this.setState({text})} keyboardType='numeric' > {item.unit} ):( ); return ( {textInput} {item.title} {item.subTitle} {bottomBtns} ) }} {normalContent}
导入后直接放到render()里,AlertView_NetRequest,注意使用位置,一定是最上层,同时设置标记 ref={ref=>{this.netRequestAlert=ref}},便于显示组件,开始请求,结果返回的显示
render() { var sub = '最低起购金额'+this.max+'万'; var firstItem ={ title:'申请额度', subTitle:sub, cancleBtn:undefined, confirmBtn:'确定', unit:'万',输入框的单位 placeHolder:'请输入申请金额',///占位符 }; var secondItem={ title:'您的额度申请已提交', subTitle:'在额度申请查询中查看审核结果', cancleBtn:'取消', confirmBtn:'额度申请查询', }; return() } {this._renderHeader()} {this._renderSalesInfoView()} {this._renderContents()} {this.netRequestAlert=ref}} style={ {marginTop:Const.screen_height/3.0}} firstItem = {firstItem} secondItem = {secondItem} firstConfirmBtnClicked = {this._alertConfirmBtnClicked} secondConfirmBtnClicked = {this._alertConfirmBtnClicked} type = {1} >
this.netRequestAlert.show();
_alertConfirmBtnClicked = (text)=>{ dispatch(ProductListsActions.requestApplyTrustCount(proItem.getIn(['productId']),Const.userInfo.id,text,this._requestCallBak)); };
this.netRequestAlert.showNetResult();
注意:上面的组件研究明白了,就能封装简单的弹出窗,前一部分是全部代码,里面有个组件Button记得用自己项目里的按钮组件替换掉。喜欢的请点
