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.js
var 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">.js
bindViewTap1: function (e) {
//hex1
var 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datadata{rtime:''}btn1: function(e){this.setData({rtime : time})
}btn2:funciton(e){console.log('###@@@@@#',this.data.rtime)
}
