阅读更多关于 Excel doesn't update value unless I hit Enter

问题 I have a very annoying problem in one of my worksheets in a workbook. I am using EXCEL 2007. Any cell's value will not be updated unless I hit ENTER. Either if the formula in the cell includes an if condition, or a VLOOKUP function or even an AVERAGE function. All the calculations are set to automatic, Application.Calculation = xlAutomatic, and even the calculations for the specific worksheet are enabled, like : ws.EnableCalculation = TRUE. Furthermore, the ScreenUpdating is set to TRUE.

问题 I have a website with 2 forms. One for search and another for the login. When I use the enter key to submit, the search is always called because it is the first form on the page.

问题 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.

阅读更多关于 Bash: Check if enter was pressed

问题 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 回答1: Firstly, check whether the exit status is normal ( $? should be 0). Secondly, check that $var equals "" . 回答2: You can also check the length of the $var variable after it was set by the read call.

Context Managers in Matlab: Invoking enter in Matlab

阅读更多关于 Context Managers in Matlab: Invoking __enter__ in Matlab

I have a python package and I would like to use its classes and methods in Matlab. I know that this can be done directly since Matlab 2014b. I mean all you have to do is add py. in the beginning of your statements. So far so good, however, I couldn't figure out how to deal with context managers through MATLAB, which are invoked using the with statement. For instance, assume that we have the following class in a module called app.py, class App(object): def __init__(self, input): self._input = input self._is_open = False def __enter__(self): self._is_open = True # many other stuff going after

vue监听键盘回车事件--Enter

阅读更多关于 vue监听键盘回车事件--Enter

vue监听键盘回车事件--Enter 方法一：keyup.enter vue文档提供了一种按键修饰符的方法: < input v-on:keyup.enter= "submit"> （keyCode事件已经被废弃），这种方法的使用前提是使用的当前元素必须要获取focus焦点，如果没有获取到焦点，绑定就会失效，因此给div或者p进行事件监听时，这种方法显示是不适用的；方法二：document.addEventListener监听keyup事件这种方法对任何元素都有效，不必须获取focus。但应该注意的是，跳出当前组件时一定要销毁监听。 mounted() { // 绑定enter事件 this.enterKeyup(); }, destroyed() { // 销毁enter事件 this.enterKeyupDestroyed(); }, methods: { enterKey(event) { const componentName = this.$options.name; if (componentName == "Login") { const code = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode; if (code == 13) { this.login();
