Flex的丰富文本处理能力实在不敢恭维

• target: Specifies the name of the target window where you load the page.  Options include _self, _blank, _parent, and  _top. The _self option specifies the current frame in the current window,  _blank specifies a new window, _parent specifies the parent of the  current frame, and _top specifies the top-level frame in the current window.
• href: Specifies a URL. The URL can  be either absolute or relative to the location of the SWF file that  is loading the page. An example of an absolute reference to a URL is  http://www.adobe.com; an example of a relative reference is  /index.html. Absolute URLs must be prefixed with http://; otherwise, Flash treats them as relative URLs.  Note: Unlike the TextField class, ActionScript link events  are not supported. Neither are a:link, a:hover, and a:active styles.

• color: Only hexadecimal color (#FFFFFF) values are supported.
• face: Specifies the name of the font to use. As shown in the following example,  you can specify a list of comma-delimited font names, in which case Flash Player selects the first available  font. If the specified font is not installed on the local computer system or isn't embedded in the SWF file,  Flash Player selects a substitute font.
• size: Specifies the size of the font. You can use absolute pixel sizes, such as 16 or 18.  Note: Unlike the TextField class, you cannot use relative point sizes, such as +2 or -4.

The <img> tag supports the following attributes:

• src: Specifies the URL to an image or SWF file, or the linkage identifier for a movie clip  symbol in the library. This attribute is required; all other attributes are optional. External files (JPEG, GIF, PNG,  and SWF files) do not show until they are downloaded completely.
• width: The width of the image, SWF file, or movie clip being inserted, in pixels.
• height: The height of the image, SWF file, or movie clip being inserted, in pixels.
• align: Specifies the horizontal alignment of the embedded image within the text field.       Valid values are left and right. The default value is left.

Note: Unlike the TextField class, the following attributes are not supported: hspace, vspace,  id, and checkPolicyFile.

Flash displays media embedded in a text field at full size. To specify the dimensions of the media  you are embedding, use the <img> tag height and width  attributes.

In general, an image embedded in a text field appears on the line following the  <img> tag. However, when the <img> tag  is the first character in the text field, the image appears on the first line of the text field.

• align: Specifies alignment of text within the paragraph; valid values are left, right, justify, and center.
• Note: Unlike the TextField class, the class attribute is not supported.

• Note: Unlike the TextField class, the class is not supported.

The <textformat> tag lets you use a subset of paragraph formatting  properties of the TextFormat class within text fields, including line leading, indentation,  margins, and tab stops. You can combine <textformat> tags with the  built-in HTML tags.

The <textformat> tag has the following attributes:

• indent: Specifies the indentation from the left margin to the first character  in the paragraph; corresponds to TextFormat.indent. Both positive and negative  numbers are acceptable.
• leftmargin: Specifies the left margin of the paragraph, in points; corresponds  /* to TextFormat.leftMargin.
• rightmargin: Specifies the right margin of the paragraph, in points; corresponds  to TextFormat.rightMargin.

Note: Unlike the TextField class, the following attributes are unsupported: blockindent, leading, and tabstops.
