使用actionscript 3裁切字符串
使用actionscript 3裁切字符串
提问于 2010-05-26 11:30:17
我正在尝试从字符串的前部和尾部修剪空格。看起来as3没有trim函数。有人知道如何做到这一点吗？

在名为StringUtil => http://livedocs.adobe.com/flex/3/langref/mx/utils/StringUtil.html#trim%28%29的实用程序类中有一个名为trim的方法

你看过奥多比的文档了吗？http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/String.html
package {
import flash.display.Sprite;
public class StringExample extends Sprite {
public function StringExample() {
var companyStr:String = new String(" Company X");
var productStr:String = "Product Z Basic ";
var emptyStr:String = " ";
var strHelper:StringHelper = new StringHelper();
var companyProductStr:String = companyStr + emptyStr + productStr;
trace("'" + companyProductStr + "'"); // ' Company X Product Z Basic '
companyProductStr = strHelper.replace(companyProductStr, "Basic", "Professional");
trace("'" + companyProductStr + "'"); // ' Company X Product Z Professional '
companyProductStr = strHelper.trim(companyProductStr, emptyStr);
trace("'" + companyProductStr + "'"); // 'Company X Product Z Professional'
}
}}
类StringHelper {
public function StringHelper() {
}
public function replace(str:String, oldSubStr:String, newSubStr:String):String {
return str.split(oldSubStr).join(newSubStr);
}
public function trim(str:String, char:String):String {
return trimBack(trimFront(str, char), char);
}
public function trimFront(str:String, char:String):String {
char = stringToCharacter(char);
if (str.charAt(0) == char) {
str = trimFront(str.substring(1), char);
}
return str;
}
public function trimBack(str:String, char:String):String {
char = stringToCharacter(char);
if (str.charAt(str.length - 1) == char) {
str = trimBack(str.substring(0, str.length - 1), char);
}
return str;
}
public function stringToCharacter(str:String):String {
if (str.length == 1) {
return str;
}
return str.slice(0, 1);
}}
