read是一个重要的命令，用于从键盘或标准输入中读取输入。 一般只有按回车键的时候才标志输入完毕，但有些情况下没法按回车键，read提供了一种不需要按回车键的方法。 1.-p “提示语句” 变量名 [wang@localhost 桌面]$ vim testcmd.sh #!/bin/bash read -p "Enter your name :" name1 name2 //name1前面要 空格 ，可以赋值给多个变量 echo $name1 echo $name2 [wang@localhost 桌面]$ chmod +x testcmd.sh [wang@localhost 桌面]$ ./testcmd.sh Enter your name :william sam william sam [wang@localhost 桌面]$ ./testcmd.sh Enter your name :william sam linux // 多余的输入会赋值给最后一个变量 william sam linux 2.-n 输入个数 当输入 字符 数达到预定数目，则自动退出，不用按回车。 [wang@localhost 桌面]$ read -n 4 -p "Enter your name :" name;echo $name Enter your name :wangwang /

I have a problem with the key Enter in javascript and asp.net I have a control like this with a textchanged event which does a find but I want to control it when the user does enter <asp:TextBox ID="TextBox1" runat="server" onkeyup="EnterEvent(event)" AutoPostBack="true" OnTextChanged="TextBox1_TextChanged" /> That's why I created this javascript function which works very well. Because it avoids the Enter postback at any character input function EnterEvent(e) { var keycode = (e.keyCode ? e.keyCode : e.which); if (keycode == 13) { return true; } else { return false } } And then I wanted to

How can I check in Bash if the Enter key has been pressed? I'm using the read command: read -p "Please press ENTER" var Firstly, check whether the exit status is normal ( $? should be 0). Secondly, check that $var equals "" . You can also check the length of the $var variable after it was set by the read call. If it's 0, the user just hit enter without typing anything else: read -p "Please press ENTER" var if [ ${#var} -eq 0 ]; then echo "Enter was hit" fi Anton try this: read var echo $REPLY|hexdump -C 来源： https://stackoverflow.com/questions/10385782/bash-check-if-enter-was-pressed

过渡和动画 　　使用<transition> 组件包裹 　　例：　　<transition name="fade"> 　　　　　　　　<div v-if="true">过渡动画</div> 　　　　　　</transition> 　　style：.fade-enter-active, .fade-leave-active {transition: opactiy .5s} 　　　　　.fade-enter, .fade-leave-to{opacity:0;} 　　以上切换v-if的状态能够让div元素渐显渐隐，而不是直接添加删除 　　原理是VUE通过tansition组件的name属性值，然后使用它在过渡的各个节点为包含的元素添加类名。当元素被添加到文档或者从文档中移除时，会分别应用enter和leave两类过渡。以下是会添加的类名： 　　　　{name}-enter（常用）:这个类名会在元素被插入DOM时加入，然后在下一帧立刻移除。可以使用它来设置那些需要在元素开始进入过渡时移除的CSS属性。 　　　　{name}-enter-active（常用）: 在元素整个动画阶段应用。和-enter 同时被添加，然后在动画完成时被移除。适用于设置css过渡时间长度，过渡的属性和使用的曲线函数。 　　　　{name}-enter-to: 这个类名会在

I've blocked Enter (return) key, actually, transformed it in Tab key. So when pressed inside input text fields it acts as Tab key. This is good, but I need it to trigger the submit button when pressed in the last field, below is the code for the Enter key mutation: $('input').keydown(function(event) { if(event.which == 13) { event.preventDefault(); $(this).nextAll('input:first').focus(); } }); And the form code is a sequence of input type="text" and a button type="submit" at the end [Edited] Actually the code is this one, taken from jquery: Enter to Tab trigger in specific parts . But I don't
