一起使用 Flash AS2 embedFonts = true AND textField.onSetFocus() 时出现问题

我注意到 AS2 和在使用 createTextField() 添加到舞台的文本字段中使用字体时出现一些奇怪的行为。这是针对最初显示“年份”的文本字段 - 用户可以输入年份，单击“确定”，该年份被接受，然后文本字段恢复为“年份”。我希望它始终是无衬线字体，例如 Arial （当然这并不困难！）

这是我想要实现的目标 -

1）当用户单击文本字段时，单词“年份”被清除，并且闪烁的光标表示可以输入文字。 2）当用户单击“确定”（并提供年份是四位数字）时，文本字段会返回“年份”（Arial 格式）

我的代码 -

this.createTextField("uiYear", 99, 0, 0, 65, 20);
uiYear.type = "input";
uiYear.antiAliasType="advanced";
uiYear.restrict = "0-9";
//
var my_fmt:TextFormat = new TextFormat();
my_fmt.font = "Arial";
my_fmt.size = 12;
my_fmt.align = "left";
//
uiYear.embedFonts = true;
uiYear.setTextFormat(my_fmt);
uiYear.text = "Year";
//
uiYear.onSetFocus = function() {
  if(uiYear.text == "Year") {
      uiYear.text = "";
  }
}
//
button_ok.onRelease = function() {
  uiYear.text = "Year";
}

看起来不错吧？

我注意到的是 -

当我单击文本字段时，“年份”一词消失，但闪烁的光标不显示，并且我无法在文本字段中输入文本。如果我删除该行 -

uiYear.embedFonts = true;

...那么它就可以正常工作，“年份”一词消失，当我单击文本字段时，我可以在文本字段中输入数字。因此，嵌入字体似乎可以防止在触发 onSetFocus 函数后将焦点设置在 textField 上。然而，我现在输入的文本不是 Arial，当我单击“确定”按钮并且“年份”一词被替换时，它是衬线字体 - 例如 Times 或其他字体。我不想那样！

同样，如果我尝试嵌入库中的字体 - 例如，我的库中有一个新字体，我使用链接标识符year_font 将其导出到actionscript，并更改my_fmt.font=my_font，然后单击链接对话框中的Export for actionscript。然后，当我单击文本字段时，“年份”一词消失，但无法编辑文本字段。

如果我只是接受 onSetFocus 导致问题并继续保留看起来更好的嵌入字体，我会遇到更多问题 -

如果我单击文本字段，光标现在会出现在“年份”一词之后，正如我所期望的那样，因为我有删除了删除单词的 onSetFocus 函数。因此，如果我通过按退格键 4 次来删除“年份”，那么由于某种原因，光标会消失并且我无法输入文本。请注意，在本地测试时不会发生这种情况，但仅在浏览器中发布和运行时才会出现问题。
但是，如果我突出显示“年份”一词，然后开始输入，我就可以正常输入数字，如果我点击“确定”按钮，年份一词就会以正确的字体显示。奇怪的是，现在上面第 1 条中的行为不再发生 - 如果我按删除键删除年份一词，光标会保留下来，我可以再次输入。第一似乎只是第一次发生。

有什么想法吗？

谢谢

I am noticing some strange behaviour with AS2 and using fonts in a textField that is added to the stage using createTextField(). This is for a textField which originally says Year - and user can enter a year, click ok and the year is accepted then the textField reverts back to saying Year. I want this to always be a sans serif font, such as Arial (surely this cant be difficult!)

Here is what I want to achieve -

1) When user clicks on textField, the word "Year" is cleared and flashing cursor indicates that text can be entered.
2) When user clicks ok (and provided year is a four digit number) the textField goes back to saying "Year" (in Arial)

My code -

this.createTextField("uiYear", 99, 0, 0, 65, 20);
uiYear.type = "input";
uiYear.antiAliasType="advanced";
uiYear.restrict = "0-9";
//
var my_fmt:TextFormat = new TextFormat();
my_fmt.font = "Arial";
my_fmt.size = 12;
my_fmt.align = "left";
//
uiYear.embedFonts = true;
uiYear.setTextFormat(my_fmt);
uiYear.text = "Year";
//
uiYear.onSetFocus = function() {
  if(uiYear.text == "Year") {
      uiYear.text = "";
  }
}
//
button_ok.onRelease = function() {
  uiYear.text = "Year";
}

Looks ok right?

What i'm noticing is this -

When I click on the textField the word "Year" disappears but the flashing cursor doesnt show and I cant enter text into the textField. If I remove the line -

uiYear.embedFonts = true;

...then it works ok, the word "Year" disappears and I can type number into the textField when I click the textField. So embedding the fonts seems to prevent focus being set on the textField after the onSetFocus function is triggered. However the text i now enter is not Arial, when I click the ok button and the word "Year" is replaced it is in a serif font - like Times or something. I dont want that!

Similarly if I try to embed a font from my library - eg I have a new Font in my library that I export to actionscript with the linkage identifier year_font and change the my_fmt.font=my_font and click Export for actionscript in the linkage dialog. Then when I click the textField, the word Year disappears but the textField cannot be edited.

If I just accept that the onSetFocus is causing the problem and go with keeping the embedded fonts which looks much better I have more probs -

If I click on the textField the cursor now appears after the word "Year" as I would expect because I have removed the onSetFocus function that deletes the word. So if I delete "Year" by pressing backspace 4 times then for some reason the cursor disappears and I cannot enter text. Note this does not happen when testing locally but is only a problem when published and running in browser.
However if I highlight the word "Year" then start typing I am able to type in numbers ok and if I hit the button ok, the word year shows up in the right font. Strangely now the behaviour in number 1 above doesnt happen anymore - if I press delete to remove the word year the cursor stays and I can type again. Number 1 only seems to happen the first time.

Any ideas?

thanks
