I need to get the value of an html input after some text has been pasted. Seems obvious to handle the input's onpaste event, but that appears to fire before the text is actually pasted.
For example...
When one pastes some text into that input the alert shows an empty string. Clicking ok then shows the pasted text appearing in the text box.
I've tried using setTimer("someFunction()", 1), then looking at the input inside someFunction(), but that seems like a kludge.
What's the best way to get to the input's text after something's been pasted?
Thanks!

I need to present arbitrary text, which might include line breaks, in a square control with word wrap such that the square is as small as possible but sufficiently large to display the text in its entirety.
This is the closest I've gotten so far:
Load the text into a temporary rich text box, Rich, with BorderStyle = none
I increment the value of size, width=height=size until Rich.ClientRectangle.Width = Rich.Width.
If I could now extract the visual lines one by one I would be done, as I could then save the original string with appropriate line breaks for later display.
Visual lines are not, of course, the same as Rich.Lines array.
Any ideas?
Thank you.
I have a sketch in processing I am working on which contains a textfield and a submit button. When the submit button is pressed, a file with is created using the name given in the textfield. I want to make sure something has been entered into the textfield when the submit button is pressed, however, it appears that by default the string is not empty or contain white space and is not caught by if statements.
Is there any simple way to check that something has been entered in the text field without needing to resort to something like regex?
I am not sure I understood whether by default your string is not empty and also does not contain white space (which would make it an odd example). The best possible check I can think of is to trim whatever the entered string is and then check if it is empty:
if(enteredString.trim().length() > 0) println("The string is valid");
the trim() method trims leading and trailing spaces, so if there are only spaces they will be removed making the string empty. Also, since you are saving files you might want to check for invalid characters. With Processing (Java) you don't necessarily have to resort to regex since you can do stuff like these:
String s = "ashd/ah";
println(s.contains("/"));
println(s.replace("/","-"));
which will print:
true
ashd-ah
Background
I want to be able to select some text, hit a keystroke that pastes what is on the clipboard over that selection, but at the same time copying that selection to the clipboard. I often find myself doing this operation when switching variables, etc from place to place.
Example
First sentence here, I need to switch it with the second sentence below. (ctrl-c)
...
Second sentence here, I am going to put this where the first one is.
///////
First sentence here, I need to switch it with the second sentence below.
...
First sentence here, I need to switch it with the second sentence below. (ctrl-"vc" after selecting second sentence, first sentence pasted, second sentence copied now)
///////
Second sentence here, I am going to put this where the first one is. (ctrl-v)
First sentence here, I need to switch it with the second sentence below.
My question
Does anyone know if any IDE/software supports such a paste/copy functionality? Has anyone ever run into this?
More specifically, does any one know how to set up a keyboard shortcut to do this in sublime text 2?
You can do it with a plugin. I threw this together rather quickly. I don't do anything special for multiple cursors (though it should take the content of multiple cursors as well as paste to all the proper locations).
import sublime
import sublime_plugin
class PasteAndCopyCommand(sublime_plugin.TextCommand):
def run(self, edit):
view = self.view
current_content = []
cursors = view.sel()
for cursor in cursors:
current_content.append(view.substr(cursor))
for cursor in cursors:
view.replace(edit, cursor, sublime.get_clipboard())
sublime.set_clipboard("\n".join(current_content))
After you save the plugin, use paste_and_copy as the the command for your key binding or command palette entry.
If I select a variable (not just any string) in my code, all other instances of that variable get a stroke (white outline) around them:
Is there a keyboard shortcut that will let me select all of those instances of the variable and edit them all at once?
Things I've Tried:
⌘D, ⌘K, and ⌘U lets me select them one-by-one, but I have to manually exclude the non-variable string matches:
And using Ctrl⌘G simply selects all the string matches:
Clearly, Sublime is able to differentiate between variable and string matches. Is there no way to select just the variable matches?
Put the cursor in the variable.
Note: the key is to start with an empty selection. Don't highlight; just put your cursor there.
Press ⌘D as needed. Not on a Mac? Use CtrlD.
Didn't work? Try again, making sure to start with nothing selected.
More commands:
Find All: Ctrl⌘G selects all occurences at once. Not on a Mac? AltF3
Undo Selection: ⌘U steps backwards. Not on a Mac? CtrlU
Quick Skip Next: ⌘K⌘D skips the next occurence. Not on a Mac? CtrlKCtrlD
Sublime Docs
I know the question is about Macs, but I got here searching the answer for Ubuntu, so I guess my answer could be useful to someone.
Easy way to do it: AltF3.
Despite much effort, I have not found a built-in or plugin-assisted way to do what you're trying to do. I completely agree that it should be possible, as the program can distinguish foo from buffoon when you first highlight it, but no one seems to know a way of doing it.
However, here are some useful key combos for selecting words in Sublime Text 2:
Ctrl⌘G - selects all occurrences of the current word (AltF3 on Windows/Linux)
⌘D - selects the next instance of the current word (CtrlD)
⌘K,⌘D - skips the current instance and goes on to select the next one (CtrlK,CtrlD)
⌘U - "soft undo", moves back to the previous selection (CtrlU)
⌘E, ⌘H - uses the current selection as the "Find" field in Find and Replace (CtrlE,CtrlH)
This worked for me. Put your cursor at the beginning of the word you want to replace, then
CtrlK, CtrlD, CtrlD ...
That should select as many instances of the word as you like, then you can just type the replacement.
The Magic is, you have to start with an empty selection, so put your cursor in front of the word/character you want to multi-select and press Ctrl+D .
To me, this is the biggest mistake in Sublime. Alt+F3 is hard to reach/remember, and Ctrl+Shift+G makes no sense considering Ctrl+D is "add next instance to selection".
Add this to your User Key Bindings (Preferences > Key Bindings):
{ "keys": ["ctrl+shift+d"], "command": "find_all_under" },
Now you can highlight something, press Ctrl+Shift+D, and it will add every other instance in the file to the selection.
As user1767754 said, the key here is to not make any selection initially.
Just place the cursor inside the variable name, don't double click to select it. For single character variables, place the cursor at the front or end of the variable to not make any selection initially.
Now keep hitting Cmd+D for next variable selection or Ctrl+Cmd+G for selecting all variables at once. It will magically select only the variables.
It's mentioned by #watsonic that in Sublime Text 3 on macOS, starting with an empty selection, simply ⌃⌘G (AltF3 on Windows) does the trick, instead of ⌘D + ⌃⌘G in Sublime Text 2.
At this moment, 2020-10-17, if you select a text element and hit CTRL+SHIFT+ALT+M it will highlight every instance within the code chunk.
Just in case anyone else stumbled on this question while looking for a way to replace a string across multiple files, it is Command+Shift+F
