我目前有一个表单可以禁用基于两个文本字段的发送按钮。一个字段是一个消息框。我想拥有它,这样一个人就不能只放一堆入口和空间。我目前检查空格,但 charAt 只返回一个空格:/ 这是我希望它的样子:
_sendComposeBtn.visible = true;
// if the length of the message is zero, don't let people send it
if (_messageLength == 0)
{
trace("hiding");
_sendComposeBtn.visible = false;
_realMessage = false;
}
_allSpaces = true;
// start with allSpaces true. If there is a nonspace (or non-enter character then hide send button
for (i = 0; i < _bigMessageTextField.length; i++)
{
if (_bigMessageTextField.text.charAt(i) != " " && _bigMessageTextField.text.charAt(i) != (ENTER_CHARACTER))
{
trace("not a space");
_allSpaces = false;
}
}
if (_allSpaces == true)
{
_sendComposeBtn.visible = false;
}
