问题 I currently have a textarea which I requires control over text that has been pasted in, essentially I need to be able to take whatever the user wants to paste into a textarea and place it into a variable. I will then work out the position in which they pasted the text and the size of the string to remove it from the textarea, Then at the end deal with the text thats is in the variable in my own way. My question: how would I go about getting a copy of the text in a variable that was just

问题 I have a Data Frame df0 with n columns. Only one of the columns contains a string, all other columns are empty or contain the "" string. Is it possible to collapse the data frame into a single column data frame where for each row I get the non-empty element? df0: A B C 1 Car 2 Car 3 Bike 4 Car 5 Train 6 Train should give: 1 1 Car 2 Car 3 Bike 4 Car 5 Train 6 Train 回答1: Maybe: >>> df.max(axis=1) 1 Car 2 Car 3 Bike 4 Car 5 Train 6 Train dtype: object which is a Series , not a DataFrame , but

Can I add a custom paste option to the windows text editing context menu?

孤者浪人 提交于 2019-12-07 06:51:26
I am looking for a way to add an option(s) to the right click context menu when editing text on a WinXP machine. I already do a lot of copy/pasting on it, so the clipboard is always changing, but there is one string I type repeatedly in almost every file I edit. I've already added some custom option to the context menu for .zip files to batch unzip them, but I'm not having any luck finding a way to add this. The machine is used for a single purpose and I try to keep it as stable as possible so I'm trying to stay away from any new third-party software that could bloat the system. I don't think

问题 How can I paste from clipboard using jQuery ? 回答1: I don't think you can do this using javascript. Since clipboard data is part of the operating system your javascript code ill not be able to access that. 回答2: It may be possible in some browsers/environments using document.execCommand , but shouldn't be relied on and you're better off finding another solution. For posterity: document.execCommand('paste', false, null); 回答3: There is a very good JS / Flash library for this: Zero Clipboard Its

How can you catch a contentEditable paste event?

旧街凉风 提交于 2019-12-07 01:27:42
问题 I've got a great editable text area going with wysihat and contentEditable. I really need a way to intercept paste events to either stop them, or process their DOM before allowing insertion. It's a little crazy they people can paste entire webpages into the editable areas. Is this possible? Come on future, arrive on my doorstep. HTML5 gurus, fire! 回答1: You can't access the content's that will be inserted. What you can do is add an event listener that runs some cleanup code on Ctrl+V (with a

“Paste” string variable in excel VBA instead of the contents of clipboard?

天涯浪子 提交于 2019-12-06 21:35:32
I have a string variable that contains an HTML table in excel VBA. I know that when this table is stored in the clipboard and I invoke .PasteSpecial, Excel does some nifty preprocessing and fills the cells out in the current sheet the same way as they appear in the table. However, if I simply set the .Value of a cell/range to the string variable, no such preprocessing takes place and the entire string, HTML tags and all, are dumped into the cell. I want the former result, but I cannot use the clipboard because it is being used by this application elsewhere and there is no guarantee I would not

问题 In text fields of my JSP, I wish to know whether user is typing in the data or just pasting. How can I identify this using javascript ? EDIT: As per Andy's answer I know how I can go about it, but still curios how those guys wrote onpaste event. 回答1: Safari, Chrome, Firefox and Internet Explorer all support the onpaste event (not sure about Opera). Latch onto the onpaste event and you will be able to catch whenever something is pasted. Writing this is simple enough. Add the event handler to

Wpf MVVM How to handle TextBox “paste event” in the ViewModel

你。 提交于 2019-12-06 04:49:11
I develop application with using MVVM pattern. I using MVVMLight library to do this. So if I need to handle TextBox TextChange event I write in XAML: <I:EventTrigger EventName="TextChanged"> <I:InvokeCommandAction Command="{Binding PropertyGridTextChange}"/> </I:EventTrigger> where PropertyGridTextChange is Command in ViewModel . But TextBox has no Paste event! This solution only works if application don't use MVVM pattern, because you need to have link on TextBox . <DataTemplate x:Key="StringTemplate"> <TextBox Text="{Binding Value, ValidatesOnDataErrors=True, Mode=TwoWay, UpdateSourceTrigger

Paste only plain-text into editable div

问题 i need to be able to allow a user to paste into an editable div (via whatever the user chooses: right-click and paste, shortcut key, etc), but i want to discard formatting and only take the plain text. i can't use a textarea since the div will allow basic formatting (bold and italic) if applied by user-initiated events. the onbeforepaste event looked promising, but according to quirksmode the support is so limited as to be unusable. tyia for any suggestions 回答1: This is tricky but not
