How to Jquery each complete

由 做~自己de王妃 提交于 2019-12-10 04:29:13
问题 I did not do the complete in $.each(). how this is done ? Please help me $("element").each(function (i, v) { //No problem }, function () { //How to complete finished ?? // alert(each finish); }) 回答1: To execute code after the each loop is over : var count = $("element").length; $("element").each(function (i) { // loop if (i+1 === count) { // this will be executed at the end of the loop } }); 回答2: The promise() method is usually for AJAX, but it can be used with each() to achieve what you want

java如何获取mac物理地址

由 若如初见. 提交于 2019-12-10 03:46:22
前言 原本以为这功能调用一个api就完事了，然而，查了一下没那么简单，网上查的资料实在忍不住要拿出来说说，估计真的都没有试过其他环境，而且，估计连背后的原理都没了解就用了。。 下面先说说找到的几份资料： ps：本机相关ip信息： 第一篇参考 Java获取本机MAC地址 点评：实际运行效果如下： 空指针啊。。。那么我们如果换个ip来试试？ 第二篇参考 使用java获取本机mac 看看代码： import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class getmac{ public static String getLinuxMACAddress() { String mac = null; BufferedReader bufferedReader = null; Process process = null; try { process = Runtime.getRuntime().exec(“ifconfig enp4s0”); bufferedReader = new BufferedReader(new InputStreamReader( process.getInputStream())); String line =

jQuery: animated, continuous loop through children

由 蓝咒 提交于 2019-12-10 03:17:18
问题 Close but not quite there. I'd like to have the first child div displayed for a couple seconds, slide down (via positioning) and fade out of view, then the next child slide up and fade into view. Repeat continuously, looping back after the last child is displayed. Looks like I've got the loop working though the count seems to pile the child divs on top of each other. What am I doing wrong? http://jsfiddle.net/rrbaker/Xmk2y/4/ 回答1: Here's my remix: http://jsfiddle.net/ddrace/DJuV7/1/ I

php array 处理函数

由 不打扰是莪最后的温柔 提交于 2019-12-09 16:57:27
current current -- 返回数组中的当前单元 说明 mixed current ( array &array ) 每个数组中都有一个内部的指针指向它“当前的”单元，初始指向插入到数组中的第一个单元。 current() 函数返回当前被内部指针指向的数组单元的值，并不移动指针。 如果内部指针指向超出了单元列表的末端， current() 返回 FALSE 。 警告 如果数组包含有空的单元（0 或者 ""，空字符串）则本函数在碰到这个单元时也返回 FALSE 。 这使得用 current() 不可能判断是否到了此数组列表的末端。 要正确遍历可能含有空单元的数组，用 each() 函数。 例 1. current() 及相关函数的用法示例 <?php $transport = array( 'foot' , 'bike' , 'car' , 'plane' ); $mode = current ( $transport ); // $mode = 'foot'; $mode = next ( $transport ); // $mode = 'bike'; $mode = current ( $transport ); // $mode = 'bike'; $mode = prev ( $transport ); // $mode = 'foot'; $mode = end
