javasciprt程式碼：

<input name="textfield" type="text"  value="浮水印自訂文字" style="color: #AAAAAA;" onfocus="if (this.value == '浮水印自訂文字') {this.value = ''; this.style.color='#333333'}" onblur="if (this.value == '') {this.value = '浮水印自訂文字'; this.style.color='#AAAAAA'}" >

程式碼(AS3)：

view sourceprint?

01	// txtfield1 是要放浮水印的目標文字欄位

02	txtfield1.addEventListener (FocusEvent.FOCUS_OUT, addTextDefault);

03	txtfield1.addEventListener (FocusEvent.FOCUS_IN, removeTextDefault);

04

05	var default_tf = txtfield1.getStyle ("textFormat");

06

07	function addTextDefault (e) {

08	if (e.currentTarget.text == "") {

09	e.currentTarget.setStyle ("textFormat", new TextFormat(null,null,0xAAAAAA));

10	e.currentTarget.text = "←請輸入資料";

11

}

12

}

13	function removeTextDefault (e) {

14	if (e.currentTarget.text == "←請輸入資料") {

15	e.currentTarget.setStyle ("textFormat", default_tf);

16	e.currentTarget.text = "";

17

}

18

}

19	addTextDefault ({currentTarget:txtfield1});

很短的程式碼, setStyle函式是用來設定組件的樣式
