备份并分享一下

var line:TextFlowLine;

var arrayLine:Array = new Array();

var text:String = "";

var dlim:int = 0;

for(var n:int = 0; n < realCount; n++) {
line = textarea.textFlow.flowComposer.getLineAt(n);
text = textarea.text.slice(dlim,dlim+line.textLength);
dlim = dlim+line.textLength;
arrayLine.push(text);
}
