一、调取参数

直接调取当前js中的方法,

调取参数that.bindViewTap();

二、跳转页面

navigateTo: function () {wx.navigateTo({ url: '../page4/page4' });},  全局变量使用方法a.jsvar app = getApp()Page({data: {hex1: [],})}//设置全局变量if (hex1 != null) {app.globalData.hex1 = hex1;} b.js接收全局变量var app = getApp()Page({ data:{  hex1:[] }, onLoad:function(options){   this.setData({   hex1:getApp().globalData.hex1  }); }, })

三、获取事件的方法:

获取事件的方法:bindViewTap1: function (e) {console.log('事件event',e)} 监听input方法a.wxml页面<input type="number" maxlength="2" placeholder="小于100分钟" placeholder-class="psection" bindinput="listenerTimeInput" /> a.js页面//监听input框输入listenerTimeInput: function (e) {this.data.time = e.detail.value;console.log('哒哒this.data.time', this.data.time)}, 获取当前时间戳var timestamp = Date.parse(new Date());timestamp = timestamp / 1000;console.log("当前时间戳为:" + timestamp); 时间转换为秒var stime = '';var format = '';stime = time * 60;console.log('秒', stime); 转换为时间Date.prototype.format = function (format) {var date = {"M+": this.getMonth() +1,"d+": this.getDate(),"h+": this.getHours(),"m+": this.getMinutes(),"s+": this.getSeconds(),"q+": Math.floor((this.getMonth() +3) /3),"S+": this.getMilliseconds()};if (/(y+)/i.test(format)) {format = format.replace(RegExp.$1, (this.getFullYear() +'').substr(4 - RegExp.$1.length));}for (var kin date) {if (new RegExp("(" + k +")").test(format)) {format = format.replace(RegExp.$1, RegExp.$1.length == 1? date[k] : ("00" + date[k]).substr(("" + date[k]).length));}}return format;}var oktime = '';oktime = newDate.format('yyyy-MM-dd h:m:s'); //获取当前时间var date = new Date();var seperator1 = "-";var seperator2 = ":";var month = date.getMonth() + 1;console.log('大大', month);var strDate = date.getDate();if (month >= 1 && month <= 9) {month = "0" + month;}console.log('大大', month);if (strDate >= 0 && strDate <= 9) {strDate = "0" + strDate;}var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate + " " + date.getHours() + seperator2 + date.getMinutes() + seperator2 + date.getSeconds();console.log('当前时间', currentdate);console.log('年', date.getFullYear());console.log('月', month);console.log('日', date.getDate());console.log('时', date.getHours())console.log('分', date.getMinutes())  转为串oktime = oktime.toString(); 提取数值var oktime = oktime.replace(/[^0-9]/ig, "");console.log('oktime', oktime); 获取年 月 日 时 分 秒var year1 = '';var month1 ='';var date1 ='';var hours1 ='';var min1 ='';year1 = oktime.substring(2, 4);console.log('year1', year1);month1 = oktime.substring(4, 6);console.log('month1', month1);date1 = oktime.substring(6, 8);console.log('date1', date1);hours1 = oktime.substring(8, 10);console.log('hours1', hours1);min1 = oktime.substring(10, 12);console.log('min1', min1); 转换为16进制  var zhen4000 = parseInt(zhen400);  console.log('飞zhen4000', zhen4000)    zhen4000 = zhen4000.toString(16); console.log('@@@@@zhen4000', zhen4000); 将值由16进制转10进制zhen1 = parseInt(zhen001, 16); // 进行异或运算//注:我使用过16进制的异或运算,没成功,最后使用了比较复杂的方法,由十六进制转化为十进制异或运算,将得到的值在转为十六进制zhen9 = zhen1 ^ zhen2

四、点击事件url传值

点击事件url传值wx.redirectTo({url: '../page1/page1?deviceId='+title+'&name='+name,success: function(res){// success}, .js传值到.wxml页面js页面this.setData({ntc: ntc,result: ntc})wxml页面<rich-text class='tep'>{{ntc}}℃</rich-text> .wxml页面bindtap点击事件传值到.js 页面跳转 监听id传值bindtap="bindViewTap1"值触发到到js里面的bindViewTap1:function方法.wxml<navigatorbindtap="bindViewTap1"id='time1'url="../page5/page5"hover-class="navigator-hover"> .jsbindViewTap1: function (e) {//hex1var id = e.currentTarget.id;console.log('坎坎坷坷扩id',id);} 设置跳出循环//跳出循环,只运行一次在data()里面添加flag : '',在你使用的方法里面加var flag = true;if (flag) {that.bindViewTap3();that.bindViewTap2();flag = false;}  函数间传值//设置全局data data{rtime:''} btn1: function(e){ this.setData({   rtime : time  })} btn2:funciton(e){ console.log('###@@@@@#',this.data.rtime)}
