由 喜欢而已 提交于 2019-12-11 22:16:38

问题 How would you make a button event call a function which acts like a backspace keyboard event delete. I tried faking the dispatch keyboard event "keyup" "keydown" with keycode 8 and keynumber 8 without success. No other way than doing it by hand with begin and end select index plus substr ? I have a textinput i just want to add a button acting like a backspace. Thanks 回答1: You can use the ASCII code 8 and translate it to a char or use the escape character '\b' or you can manipulate the

How do I capture the backspace key in IE8 with jquery?

问题 I've got a simple javascript keydown event coded via jquery. The event should just alert the key that is "down." This works for most keys but not the backspace key in Internet Explorer. I read that IE messes this up on the keypress event but was supposed to work for the keydown and keyup events. Is there anything I can do via jquery to capture the backspace in IE? The version of IE I'm currently testing in is: 8.0.7600.16385 $('.AddressField').bind("keydown", function (e) { alert(e.keyCode);

问题 I'm trying to apply control characters, such as '\x08 \x08' that should remove the precedent char, to a string (move backwards, write space, move backwards) For example when I type into python console : s = "test\x08 \x08" print s print repr(s) I get in my terminal : tes 'test\x08 \x08' I'm looking for a function, let's says "function", that will 'apply' control characters to my string : v = function("test\x08 \x08") sys.stdout.write(v) sys.stdout.write(repr(v)) so I get a "clean", control

Using \\b in Python 3

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-05 18:20:58
I saw in another question that ( "\b" ) could be used to delete a character. However, when I tried \b it only put a space in between the character I was intending on deleting and the one after. Is there another way I could do backspace? (I'm trying to make a program that will write a word, delete it then rewrite a new one) bastelflp It depends on the terminal which is used and how it interprets the \b , e.g. print('Text: ABC\b\b\bXYZ') in the interactive console of PyCharm gives: Text: ABC XYZ but executed in the comand line (cmd.exe) it gives: Text: XYZ This is explained in more detail here:
