Property Detail
mxmlChildren | property |
mxmlChildren:Array| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Sets text based on content within span tags; always deletes existing children. This property is intended for use during MXML compiled import in Flex. Flash Professional ignores this property. When TLF markup elements have other TLF markup elements as children, the children are assigned to this property.
Implementation
public function get mxmlChildren():Array public function set mxmlChildren(value:Array):voidThrows
TypeError — If array element is not a SpecialCharacterElement or a String.
|
text | property |
text:String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Receives the String of text that this SpanElement object holds.
The text of a span does not include the carriage return (CR) at the end of the paragraph
but it is included in the value of textLength.
Implementation
public function get text():String public function set text(value:String):voidConstructor Detail
SpanElement | () | Constructor |
public function SpanElement()| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Constructor - creates a SpanElement object to hold a run of text in a paragraph.
Method Detail
replaceText | () | method |
public function replaceText(relativeStartPosition:int, relativeEndPosition:int, textValue:String):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Updates the text in text span based on the specified start and end positions. To insert text, set the end position equal to the start position. To append text to the existing text in the span, set the start position and the end position equal to the length of the existing text.
The replaced text includes the start character and up to but not including the end character.
Parameters
relativeStartPosition:int — The index position of the beginning of the text to be replaced,
relative to the start of the span. The first character in the span is at position 0.
| |
relativeEndPosition:int — The index one position after the last character of the text to be replaced,
relative to the start of the span. Set this value equal to relativeStartPos
for an insert.
| |
textValue:String — The replacement text or the text to add, as the case may be.
|
Throws
RangeError — The relativeStartPosition or relativeEndPosition specified is out of
range or a surrogate pair is being split as a result of the replace.
|
Example ( How to use this example )
This example calls replaceText() several times to do the following:
insert a string at the beginning of text; append a string to the end of text;
insert a string in the middle of text; replace text entirely with a new string.
The example uses a second span (span2) to display the results.
