weex开发的笔记
启动npm服务 npm run serve:lazy相当于本地发布服务，连接本地服务可实时查看weex页面的更新
向weex端注册方法和组件
/// 功能组件 [WXSDKEngine registerModule:@"MallModule" withClass:NSClassFromString(@"BHEMallWxEventModule")]; /// UI组件 [WXSDKEngine registerComponent:@"input" withClass:NSClassFromString(@"BHEWeexEditText")];
设置下载等自定义代理和注入JS函数
/// 实现自定义代理 [WXSDKEngine registerHandler:loader withProtocol:@protocol(WXImgLoaderProtocol)]; [WXSDKEngine registerHandler:loader withProtocol:@protocol(WXURLRewriteProtocol)]; /// 注入JS服务函数 /** * @abstract Registers a component for a given name, options and js code * * @param name The service name to register * * @param options The service options to register * * @param serviceScript service js code to invoke * */ + (void)registerService:(NSString *)name withScript:(NSString *)serviceScript withOptions:(NSDictionary * _Nullable)options;
Module提供方法给到weex端使用
/// weex端调用时方法名为最前面部分addEventListener(xx,(ret)=>{code;})，其他按照参数个数依次补充即可，不需要补充方法名 WX_EXPORT_METHOD(@selector(addEventListener:callback:))
weex端写一个js功能模块
/// date_utils.js const ONE_SECOND = 1000; const ONE_MINUTE = 60 * ONE_SECOND; const ONE_HOUR = 60 * ONE_MINUTE; const ONE_DAY = 24 * ONE_HOUR; export default { one_day: ONE_DAY, one_hour: ONE_HOUR, one_minute: ONE_MINUTE, one_second: ONE_SECOND, getSystemCurrTime() {//只到秒 var timestamp = Date.parse(new Date()); //var timestamp = (new Date()).valueOf(); //var timestamp=new Date().getTime(); return parseInt(timestamp / 1000); }, getSystemCurrTime2() {//精度：毫秒 var timestamp = Date.parse(new Date()); //var timestamp = (new Date()).valueOf(); //var timestamp=new Date().getTime(); return parseInt(timestamp); }, getCurrServerTime(serverTime) { if (!serverTime) { serverTime = 0; } return serverTime + this.getSystemCurrTime(); }, getTimeStrMDH(seconds) { var dateTime = new Date(seconds * 1000); var month = dateTime.getMonth() + 1; var day = dateTime.getDate(); var hour = dateTime.getHours(); return month + "月" + day + "日" + hour + "时"; }, calculateCutTime(timeInterval) { //传进来的是毫秒的时间戳 var day = parseInt(timeInterval / ONE_DAY); timeInterval %= ONE_DAY; var hour = parseInt(timeInterval / ONE_HOUR); timeInterval %= ONE_HOUR; var minute = parseInt(timeInterval / ONE_MINUTE); timeInterval %= ONE_MINUTE; var second = parseInt(timeInterval / ONE_SECOND); if (day <= 9) day = '0' + day; if (hour <= 9) hour = '0' + hour; if (minute <= 9) minute = '0' + minute; if (second <= 9) second = '0' + second; return [day, hour, minute, second]; }, getCountTime(time) { var countTime = ''; var day = parseInt(time / ONE_DAY); time %= ONE_DAY; var hour = parseInt(time / ONE_HOUR); time %= ONE_HOUR; var minute = parseInt(time / ONE_MINUTE); time %= ONE_MINUTE; var second = parseInt(time / ONE_SECOND); if (day <= 9) day = '0' + day; if (hour <= 9) hour = '0' + hour; if (minute <= 9) minute = '0' + minute; if (second <= 9) second = '0' + second; countTime = day + '天' + hour + '时' + minute + '分' + second + '秒'; return countTime; }, getCountTime3(time) { var countTime = ''; var day = parseInt(time / ONE_DAY); time %= ONE_DAY; var hour = parseInt(time / ONE_HOUR); time %= ONE_HOUR; var minute = parseInt(time / ONE_MINUTE); time %= ONE_MINUTE; var second = parseInt(time / ONE_SECOND); if (hour <= 9) hour = '0' + hour; if (minute <= 9) minute = '0' + minute; if (second <= 9) second = '0' + second; if (day > 0) { countTime = day + '天' + hour + '小时' + minute + '分'; } else { countTime = hour + '小时' + minute + '分' + second + '秒'; } return countTime; }, getCountTime2(time) { var countTime = ''; var day = parseInt(time / ONE_DAY); time %= ONE_DAY; var hour = parseInt(time / ONE_HOUR); time %= ONE_HOUR; var minute = parseInt(time / ONE_MINUTE); time %= ONE_MINUTE; var second = parseInt(time / ONE_SECOND); if (day > 0) { countTime += day + '天'; countTime += hour + '小时'; countTime += minute + '分'; countTime += second + '秒'; } else { if (hour > 0) { countTime += hour + '小时'; countTime += minute + '分'; countTime += second + '秒'; } else { if (minute > 0) { countTime += minute + '分'; countTime += second + '秒'; } else { if (second > 0) { countTime += second + '秒'; } } } } return countTime; }, dateFormat(dateTime, fmt) { if (!dateTime) { return dateTime } if (typeof dateTime == 'string' && !isNaN(dateTime)) { dateTime = +dateTime } dateTime = new Date(dateTime); var o = { "M+": dateTime.getMonth() + 1, //月份 "d+": dateTime.getDate(), //日 "h+": dateTime.getHours(), //小时 "m+": dateTime.getMinutes(), //分 "s+": dateTime.getSeconds(), //秒 "q+": Math.floor((dateTime.getMonth() + 3) / 3), //季度 "S": dateTime.getMilliseconds() //毫秒 }; if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (dateTime.getFullYear() + "").substr(4 - RegExp.$1.length)); for (var k in o) if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ?

使用定义的js功能模块时（相当于创建对象实例）
import dateUtil from './utils/date_utils.js';
引用其他vue文件的UI组件
import navigationBar from "./navigator.vue";
import noNetworking from './no_networking.vue';
import pro_tag from '../items/pro_tag.vue';
/// 通过模块名字实例化原生模块对象用作调用原生模块方法
const dom = weex.requireModule('dom');
const myModule = weex.requireModule('MallModule');
const navigator = weex.requireModule('navigator');
export default {
components: { navigationBar, noNetworking, pro_tag },
}
weex调用原生方法
getUserInfo(callback) { var msg = { "operation": "getUserInfo" }; // myModule.log('请求获取用户信息'); bridgeModule.commandInterface(JSON.stringify(msg), function (e) { var json = JSON.parse(e); // myModule.log('用户信息:' + e); if (callback) { callback(json); } }, function (failed) { // myModule.log('获取登用户息失败:' + failed); if (callback) { callback({}); } }) }, WX_EXPORT_METHOD(@selector(commandInterface:finalCallBack:finalCallbackFail:)) -(void)commandInterface:(NSString *)param finalCallBack:(WXModuleKeepAliveCallback)callback finalCallbackFail:(WXModuleKeepAliveCallback)failCallback
weex给控件赋值样式的几个方式
/// 样式应该为class加上style /// 直接在标签内作为属性编写 <text v-else-if="item.nOriginalPrice>item.nSalePrice" style="font-family: PingFang-SC-Medium;font-size: 24px;color: #C7C7CC;text-align: left;text-decoration: line-through;">¥{{item.nOriginalPrice/100.0}}</text> /// 通过函数获取 <div :style="appUtil.grayFloatStyle" v-if="appUtil.showGrayFloat()"></div> /// 通过函数给属性赋值 <div class="singleTag" :style="{backgroundColor:getTagColor(item.oTagInfo.SingleTag.TagColor),borderBottomRightRadius:item.lProMemPrice && item.lProMemPrice>0?'0':'18px'}" v-if="item.oTagInfo&&item.oTagInfo.SingleTag&&item.oTagInfo.SingleTag.TagName"> /// 通过css定义 <div class="wrapper" @click="cancelAddressSelect"> <style scoped> .wrapper { position: absolute; top: -100px; left: 0; right: 0; bottom: 0; background-color: rgba(0, 0, 0, 0.5); } .address_selector { background-color: #fff; position: absolute; bottom: 0; left: 0; width: 750px; height: 640px; border-top-right-radius: 20px; border-top-left-radius: 20px; overflow: hidden; } </style> /// 通过函数表达式获取值
给视图元素增加事件
/// @事件="函数(arvgs...)" <image :src="local_image.icon_sending_cancel" class="cancelBtn" @click="closeDialog()"></image> <input class="inputText" maxlength="30" @input="aliAccountInput" :value="aliaccount" @change="aliAccountInput"/> <list v-if="hasLoadData" style="flex: 1; width: 750px; margin-top: -1px;" @loadmore="onloadMoreHandle" @scroll="onScroll"> <div class="slider-pages" v-for="(item, i) in bannerList" :key="I" @click="jumpToActivePage(item,'banner',i)" @appear="appear(item,i)"> <app_dialog v-if="isShowNewGiftReceiveFailDialog" tipMsgText="请重试" messageText="领取失败" confirmText="确定" v-on:confirmClick="confirmReceiveGiftPackageDialog"></app_dialog> <div v-if="isShowNewGiftReceiveSuccessDialog" style="width: 750px; position: absolute; top: -88px; left: 0; bottom: 0; background-color: rgba(0,0,0,0); justify-content: center; align-items: center;"> <div style="width: 180px; height: 180px; justify-content: center; align-items: center;background-color: rgba(0,0,0,0.8); border-radius: 12px;"> <image style="width: 80px;height: 80px; margin-bottom: 20px;" :src="remote_image.receive_success"></image> <text style="font-size: 24px; color: #fff; text-align: center;">领取成功</text> </div> </div>
处理圆角等超出显示范围的时候显示效果配置的属性overflow https://www.w3school.com.cn/css/pr_pos_overflow.asp
给元素绑定别名，用于后续获取
/// ref <div v-if="showPromoteDialog" ref="refPromoteDialog" class="fullScreenDiv prompt_bg"> <div style="align-items: flex-end"> <image style="width: 100px; height: 100px; opacity: 0" :src="remote_image.close_envelope_btn" @click="closePrompt" ref="closeImg"></image> <image style="margin-top: 10px; width: 520px; height: 780px" :src="promoteDialogData.img" @click="toPromotePage" @load="onPromoteImageLoad"></image> </div> </div> const refPromoteDialog = this.$refs.refPromoteDialog; const closeImg = this.$refs.closeImg;
自定义组件通过props来提供给外部调用设置属性值
<template> <div v-if="showDialog" @click="" style="width:750px;position:absolute;top:0;bottom:0;flex:1;"> <div style="width:750px;position:absolute;top:-88px;bottom:0;background-color:#000000;opacity:0.75;flex:1;"> </div> <div class="tip-bg" style="background-color: #051C4F;"> <image style="width:534px; height: 586px;position:absolute;" :src="remote_image.dialog_fail_bg"></image> <image style="width:318px; height: 262px;margin-top:61px;" :src="remote_image.dialog_fail_headIcon"></image> <text class="tip-content">活动已下线，逛逛别的吧～</text> <image style="width:221px; height: 72px;margin-top:46px;" :src="remote_image.dialog_fail_button" @click="onClickOver"></image> </div> </div> </template> <script> import image from '../../../data/image_index.js'; import myImage from '../../../data/image_b_activity.js'; export default { data() { return { remote_image: myImage.remote }; }, props: { showDialog: { type: Boolean, default: false, } }, methods: { onClickOver() { this.$emit('onClickOver'); }, } } </script> <style scope> .tip-bg{ position:absolute; top:359px; width:534px; height:586px; margin-top:0px; margin-left:108px; align-items: center; } .tip-title{ margin-top:2px; margin-left: 151px; font-family: PingFangSC-Regular; color:#000000; font-size:34px; font-weight: bold; line-height: 34px; letter-spacing: 0; } .tip-content{ font-family: FZLTHJW--GB1-0; font-size: 24px; color: #FFFFFF; letter-spacing: 1px; text-align: center; line-height: 32px; text-shadow: 0 2px 3px rgba(0,0,0,0.50); margin-top: 19px; } </style>
自定义组件通过$emit给外界提供事件触发方法代理
export default {
data() {
return {
remote_image: myImage.remote
};
},
props: {
strUid:{
type: String,
default: null,
},
showDialog: {
type: Boolean,
default: false,
}
},
methods: {
onClickModify() {
this.$emit('onClickModify');
},
onClickSure() {
this.$emit('onClickSure');
}
}
}
