小程序的一些函数调用方法
数据缓存的地址在这: http://blog.csdn.net/qq_27229113/article/details/78123683
直接调取当前js中的其他方法,
调取参数that.bindViewTap();
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
});
},
})
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 k
in 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);
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
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
<
navigator
bindtap
=
"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data
data{rtime:''}
btn1: function(e){
this.setData({
rtime : time
})
}
btn2:funciton(e){
console.log('###@@@@@#',this.data.rtime)
}
