Jquery: An alternate method for fromcharcode() to convert integer to character

Question

I'm coding a chat box. And the Characters that I enter, is not reflected as it is.

This is basically the code I'm using.

$(document).ready(function() { $(".entry").keydown(function(event) { console.log(String.fromCharCode(event.which)); }); });

And so when I type (lower-case) "a", console tab shows me "A".

special characters will not get reflected unless I create separate condition for it.

Could someone help me with a different function which does it all by itself, and returns a string as entered by the user. Or a different approach to this challenge all together. Thanks.

Actual code - chat.js

var str=''; $(document).ready(function() { $(".entry").keydown(function(event) { console.log(event.which); if (event.which === 13 && event.shiftKey === false) { console.log(str); event.preventDefault(); } else { var c = event.which; str = str.concat(String.fromCharCode(c)); } }); });

So basically the every character entered would get concated to the string. and Enter key would dump the text to console.

Do you have any special filters applied for chat box which converts the chars? — Anand G

No i dont think so . var str=''; $(document).ready(function(){ $(".entry").keydown(function(event) { console.log(event.which); if (event.which === 13 && event.shiftKey === false) { //$(".entry").css("background-color", "blue"); //alert($(document.getElementById('entry1').innerHTML)); console.log(str); event.preventDefault(); } else { var c = event.which; str = str.concat(String.fromCharCode(c)); //console.log(String.fromCharCode(c)); } }); }); — Wisam Ahmed

It's seems that trying to get the value of event.which in keydown event could lead you to a wrong ascii code (What you need to pass to String.fromCharCode).

See https://stackoverflow.com/a/10192144/3879872

I don't know if it fits your needs, but you could try:

$(document).ready(function(){ $(".entry").keypress(function(event) { console.log(String.fromCharCode(event.which)); }); });

(Note the use of keypress instead of keydown)

EDIT: Added working Demo

var str = ''; $(document).ready(function() { $(".entry").keypress(function(event) { console.log(event.which); if (event.which === 13 && event.shiftKey === false) { console.log(str); event.preventDefault(); } else { var c = event.which; str = str.concat(String.fromCharCode(event.which)); } console.log('Formated Text', str); }); });
