How to disable pasting in a TextField in Swift?
I agree with Leonardo Savio Dabus, if I were you I’d use string checking and just give out a warning, it makes things easier. BUT, if disabling paste option is a fancy feature you really want to put into your app, then you need to do more work. I’ll provide the steps below. Step 1: … Read more
jQuery bind to Paste Event, how to get the content of the paste
There is an onpaste event that works in modern day browsers. You can access the pasted data using the getData function on the clipboardData object. $(“#textareaid”).bind(“paste”, function(e){ // access the clipboard using the api var pastedData = e.originalEvent.clipboardData.getData(‘text’); alert(pastedData); } ); Note that bind and unbind are deprecated as of jQuery 3. The preferred call … Read more
Pasting elements of two vectors alphabetically
slightly redundant because it sorts twice, but vectorised, paste(pmin(a,b), pmax(a,b)) Edit: alternative with ifelse, ifelse(a < b, paste(a, b), paste(b, a))

Split a character vector into individual characters? (opposite of paste or stringr::str_c)

Concatenate row-wise across specific columns of dataframe
Try data$id <- paste(data$F, data$E, data$D, data$C, sep=”_”) instead. The beauty of vectorized code is that you do not need row-by-row loops, or loop-equivalent *apply functions. Edit Even better is data <- within(data, id <- paste(F, E, D, C, sep=””))
Intercept paste event in Javascript
You can intercept the paste event by attaching an “onpaste” handler and get the pasted text by using “window.clipboardData.getData(‘Text’)” in IE or “event.clipboardData.getData(‘text/plain’)” in other browsers. For example: var myElement = document.getElementById(‘pasteElement’); myElement.onpaste = function(e) { var pastedText = undefined; if (window.clipboardData && window.clipboardData.getData) { // IE pastedText = window.clipboardData.getData(‘Text’); } else if (e.clipboardData && … Read more
