问题 I know that this question is answered many times, but I still can't figure out how to do it. Maybe it's because I don't know the correct keyword to search for. Using echo -ne '\n' | enter doesn't work. My code is: #! /bin/bash #Grub-customizer sudo add-apt-repository ppa:danielrichter2007/grub-customizer echo -ne '\n' | return sudo apt-get update sudo apt-get install grub-customizer 回答1: You're supposed to pipe the \n into the command that's going to be receiving it (otherwise it won't ever

Reading a sentence until ENTER key pressed using 2-D char array

与世无争的帅哥 提交于 2021-02-07 03:28:57
问题 I need to read a sentence word by word until "ENTER" key is pressed. I used a do..while loop to read words until ENTER key is pressed. Please suggest me some conditions for checking ENTER key press (or) others ways for reading similar input. #include<iostream> #include<string.h> using namespace std; int main(){ char a[100][20]={'\0'}; int i=0; do{ cin>>a[i++]; } while( \\ Enter key is not pressed ); for(int j= 0 ; j < i ; j++) cout<< a[j] << " "; return 0; } 回答1: while (cin.peek() != '\n') {

Triggering submit button with Enter keypress event and mouse click

问题 I am a total beginner and am learning front-end using a "just do it" and project-focus route. My web app will essentially work similar to that of a to-do list. I assume it is because I have "getElementById" twice for the same element. This works initially: // add idea to list button document.getElementById('btnSubmit').addEventListener("submitIdea", submitIdea); function submitIdea() { var ul = document.getElementsByClassName('anIdea')[0]; var enterIdea = document.getElementById('enterIdea');

使用JavaScript在文本框中的Enter键上触发按钮单击

梦想的初衷 提交于 2020-04-07 00:30:23
问题: I have one text input and one button (see below). 我有一个文本输入和一个按钮(见下文)。 How can I use JavaScript to trigger the button's click event when the Enter key is pressed inside the text box? 当在文本框中按下Enter键时,如何使用JavaScript 触发按钮的click事件 ? There is already a different submit button on my current page, so I can't simply make the button a submit button. 当前页面上已经有一个不同的“提交”按钮,因此我不能简单地将该按钮设为“提交”按钮。 And, I only want the Enter key to click this specific button if it is pressed from within this one text box, nothing else. 而且,如果 只 从一个文本框中按下该按钮,我 只 希望按Enter键即可单击该特定按钮,没有别的。 <input type="text" id="txtSearch" />

JQ中mouseover和mouseenter的区别

   我最近也在学习JQuery,所以最近对JQ中的一些小问题进行总结,方便学习。  在对于刚开始学习JQ的初学者来说,mouseover事件和mouseenter事件总是傻傻分不清楚,毕竟刚开始学习的时候,需求没那么详细,毕竟俩事件的大致意思都一样 ---就是鼠标移上去,就执行该事件的自定义函数。其实我们自己去看下他们的概念,我想你应该可以从中发现区别于不同:     mouseover:当鼠标指针位于元素上方时,会发生 mouseover 事件。     mouseenter:当鼠标指针穿过元素时,会发生 mouseenter 事件。   从这里的一个小插曲上,我们应该可以看出,mouseenter是穿过,所以只能触发一次改事件,而mouseover是位于上方, 可以想下,如果给div设定了一个mouseover事件,其子孙后代都可以响应改事件,so...一旦鼠标从父级进入自己也会触发这个效果,当从子集回到父级也会触发这种效果。 所以,你可以这么理解:mouseenter事件只作用于目标元素,而mouseover最用于目标元素及其后代元素。   如果还没明白,DOM案例如下:   JS代码: $(document).ready(function(){ $("div.over").mouseover(function(){ $(".over span").text(x+=1);

IBM X3650 M3 7945XJ9 Raid10 配置

某厂面试归来,发现自己落伍了!>>> IBM X3650 M3 7945XJ9 Raid10 配置 一、RAID介绍 RAID是Redundent Array of Inexpensive Disks的缩写,直译为“廉价冗余磁盘阵列”,也简称为“磁盘阵列”。后来RAID中的字母I被改作了Independent,RAID就成了“独立冗余磁盘阵列”,但这只是名称的变化,实质性的内容并没有改变。可以把RAID理解成一种使用磁盘驱动器的方法,它将一组磁盘驱动器用某种逻辑方式联系起来,作为逻辑上的一个磁盘驱动器来使用。 RAID的优点 1. 传输速率高。在部分RAID模式中,可以让很多磁盘驱动器同时传输数据,而这些磁盘驱动器在逻辑上又是一个磁盘驱动器,所以使用RAID可以达到单个的磁盘驱动器几倍的速率。因为CPU的速度增长很快,而磁盘驱动器的数据传输速率无法大幅提高,所以需要有一种方案解决二者之间的矛盾。 2. 更高的安全性。相较于普通磁盘驱动器很多RAID模式都提供了多种数据修复功能,当RAID中的某一磁盘驱动器出现严重故障无法使用时,可以通过RAID中的其他磁盘驱动器来恢复此驱动器中的数据,而普通磁盘驱动器无法实现,这是使用RAID的第二个原因。 RAID的分类 RAID 0,无冗余无校验的磁盘阵列。数据同时分布在各个磁盘上,没有容错能力,读写速度在RAID中最快
