如何删除actionscript中的一部分字符串？ [英] How to delete part of a string in actionscript?

问题描述

所以我的字符串是像BlaBlaBlaDDDaaa2aaa345我想摆脱它的子字符串是BlaBlaBlaDDD，所以操作的结果将是一个字符串aaa2aaa345如何执行这样的事情与动作？

解决方案

我只是使用 String＃用正则表达式替换方法：

  var string：String =BlaBlaBlaDDD12345; 
 var newString：String = string.replace（/ [a-zA-Z] + /，）; //12345
  

这将删除所有单词字符。如果你正在寻找更复杂的正则表达式，我会乱在网上 Rubular 正则表达式测试人员。

这将删除所有非数字字符：

  var newString：String = string.replace（/ [^ \d] + /， ）;如果你知道你想删除的确切的字符串，那么只需要这样做：/ /12345
 
  var newString：String = string.replace（BlaBlaBlaDDD，）; 
  
如果你有一个你想删除的子串的列表（数组）每个 string.replace 方法。
 
So my string is something like "BlaBlaBlaDDDaaa2aaa345" I want to get rid of its sub string which is "BlaBlaBlaDDD" so the result of operation will be a string "aaa2aaa345" How to perform such thing with actionscript?
解决方案
I'd just use the String#replace method with a regular expression:
var string:String = "BlaBlaBlaDDD12345";
var newString:String = string.replace(/[a-zA-Z]+/, ""); // "12345"
That would remove all word characters.  If you're looking for more complex regular expressions, I'd mess around with the online Rubular regular expression tester.

This would remove all non-digit characters:
var newString:String = string.replace(/[^\d]+/, ""); // "12345"
If you know the exact string you want to remove, then just do this:
var newString:String = string.replace("BlaBlaBlaDDD", "");
If you have a list (array) of substrings you want to remove, just loop through them and call the string.replace method for each.
