将光标移至文本区域内结束
我的表单上有一个文本区域控件，该控件应该接受 5 位数的美国邮政编码。我已经为控件分配了一个 keyUp 事件，该事件检查输入的字符数，直到达到 5，然后强制换行。
public function forceNewLine(event:KeyboardEvent):void
{
var maxLineChars:int = 5;
var currentLine:int = 1;
var numChars:int;
numChars = (txtList.text.length);
currentLine = Math.round(txtList.text.length / 6);
if (numChars == (maxLineChars * currentLine))
{
txtList.text = txtList.text + "\n";
txtList.setCursorPosition()
//This is not a function I have defined but I think I need too..
}
}
<s:TextArea id="txtList" keyUp="forceNewLine(event)"/>
它工作正常，只是当插入新行时，光标移动到文本区域的开头。我希望它能走到最后。
I have a text area control on a form that is supposed to accept 5 digit US zip codes. I have assigned the control a keyUp event that checks the number of characters entered until it reaches 5 then forces a new line.
public function forceNewLine(event:KeyboardEvent):void
{
var maxLineChars:int = 5;
var currentLine:int = 1;
var numChars:int;
numChars = (txtList.text.length);
currentLine = Math.round(txtList.text.length / 6);
if (numChars == (maxLineChars * currentLine))
{
txtList.text = txtList.text + "\n";
txtList.setCursorPosition()
//This is not a function I have defined but I think I need too..
}
}
<s:TextArea id="txtList" keyUp="forceNewLine(event)"/>
It works fine except that when the new line is inserted, the cursor moves to the beginning of the textarea. I want it to go to the end.

尝试使用 Spark textArea 的 selectRange 函数。
Try using the selectRange function of the spark textArea.
