I have a textarea
and I want to remove new lines from it, if the return key is pressed, without writing any text. I tried this, but it did not work:
function keypress(id) {
$("#"+id).keypress(function(event) {
$("#"+id).val().replace(/\n/g, "");
});
}
Try
function keypress(id) {
$("#" + id).keyup(function (event) {
$(this).val($(this).val().replace(/^\s*(\n)\s*$/, ''))
});
}
Demo: Fiddle
Why don't you use the Javascript trim
method.
From https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/Trim
The trim() method removes whitespace from both ends of a string. Whitespace in this context is all the whitespace characters (space, tab, no-break space, etc.) and all the line terminator characters (LF, CR, etc.).
function keypress(id) {
$("#"+id).keypress(function(event) {
$("#"+id).val().trim();
});
}
