在实际的移动应用程序交互方式中,最常见的就是滑动操作。像左右滑动切换页面,手指张开来放大图片等,都是由滑动操作来完成的。微信小程序默认提供的相关事件如下:触摸相关操作事件tap对应点击操作,还提供了longtap来支持长按操作,这些都比较简单,就不多做讲述。touchmove对应滑动操作,通过bindtouchmove即可响应滑动操作。//wxml

简介:什么是事件 事件是视图层到逻辑层的通讯方式。 事件可以将用户的行为反馈到逻辑层进行处理。 事件可以绑定在组件上,当达到触发事件,就会执行逻辑层中对应的事件处理函数。 事件对象可以携带额外信息,如id, dataset, touches。
简介:本文只提供设计思路,即js代码.完整代码,请下载demo设计思路: 1.监听整个下拉区域的touchstart事件,并记录下pageY和clientY值 2.监听整个区域的touchmove 事件,并判断是上移还是下移,以及滚动开始时,clientY和pageY是否相等,最后实现动画 3.当滑动停止的时候,头部视图变为原来的,图片恢复原样

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

在PHP中,可以利用implode()函数的第一个参数来设置没有分隔符,该函数的第一个参数用于规定数组元素之间放置的内容,默认是空字符串,也可将第一个参数设置为空,语法为“implode(数组)”或者“implode("",数组)”。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。
