如果字母 > 在 AS3 中为 10,则拆分

Split if letters > at 10 in AS3

我正在尝试拆分包含超过 10 个字母的每个单词。

我该怎么办?

我做到了:

if (item.title.length > 10){
        trace("item.length>10");
// What should I put here in order to erase the letters after the 10th one ?
}
if (item.title.length > 10){
    trace("item.length>10"); // 0

    trace(String(item.title).substring(0,10)); // if item.title is "star wars : the force" it will shows "star wars "        

    var arr:Array=String(item.title).split("");

   for(var i:int=0;i<arr.length;i++)
   {
      trace(arr[i]);// it shows every letter in the array
   }

}
    var string0:String = 'hello';
    var string1:String = 'hello this is a test string';

    // trunkate to up to 10 chars...
    string0 = string0.slice(0, 10);
    string1 = string1.slice(0, 10);

    trace('>' + string0 + '<');         // result is >hello<
    trace('>' + string1 + '<');         // result is >hello this<
