You may want to set a breakpoint within the event handler for the textarea
to track down where the new line comes from. Though it sounds like the new
line comes from hitting Enter within the textarea.
As Farshid mentioned you can prevent the default behavior (i.e. entering a
new line) when hitting Enter using
event.preventDefault()<https://developer.mozilla.org/en-US/docs/Web/API/event.preventDefault>,
though his code has a little flaw as it's not the click event you need to
react to but the keydown event. So the code would actually look something
like this (with some other improvements):
textarea.addEventListener("keydown", function(event) {
if (event.keyCode === KeyEvent.DOM_VK_RETURN) {
event.target.value = "";
event.preventDefault();
}
});
