TextField嵌入表情圖標，實現圖文混排

TextField嵌入表情圖標，實現圖文混排

 

主要代碼是

 

/**

* 定位到表情符

*/

public function posSmileWord(){

clearSM();

var pattern:RegExp = //[sm/d/]/g;

var resultArray:Array = text.match(pattern);

if(resultArray!=null){

var sta:int=0;

for each(var s:String in resultArray ){

sta = bulidSmile(s,sta);

}

}else{

trace("==沒有匹配的表情符");

}

}

 

private function bulidSmile(str:String,staIndex:int):int{

var startNum:Number = this.text.indexOf(str,staIndex);

var r = this.TargetField.getCharBoundaries(startNum);

if(r==null) return startNum+1;

 

if(this.targetField.getLineIndexOfChar(startNum)>(this.targetField.bottomScrollV-1)) return this.text.length;

//todo：將文字的表情符進行隱藏

 

 

//定位表情位置

var newSm:Smile = new Smile(str);

this.smilesArray.push(newSm);

newSm.x = r.x;

newSm.y= r.y-(this.targetField.scrollV-1)*this.targetField.getLineMetrics(0).height;

this.addChild(newSm);

return startNum+1;

}
