我有一个仅限输入数字的文本区域。我想在用户按下回车键后删除回车符。这是我的代码:
// Change tempo
function changeTempo(event:KeyboardEvent):void {
if (event.charCode == 13) {
// Some code here
}
// Remove enter char
removeCarriageReturnsAndNewLines(tempo_txt.text);
}
function removeCarriageReturnsAndNewLines($myString:String):String {
var newString:String;
var findCarriageReturnRegExp:RegExp = new RegExp("\r", "gi");
newString = $myString.replace(findCarriageReturnRegExp, "");
var findNewLineRegExp:RegExp = new RegExp("\n", "gi");
newString = newString.replace(findNewLineRegExp, "");
return newString;
}
