JavaScript 正则表达式 - i


描述

我执行不区分大小写的匹配。

例子

以下示例显示了 RegExp 表达式的用法。

<html>
   <head>
      <title>JavaScript RegExp</title>
   </head>
   
   <body>
      <script type = "text/javascript">
         var str = "abcABC";
         var pattern = /[aeiou]/ig;

         var result = str.match(pattern);
         document.write("Test 1 - returned value : " +  result); 

         pattern = /[aeiou]/g;
         result = str.match(pattern);
         document.write("<br/>Test 2 - returned value : " +  result); 	 		 
      </script>
   </body>
</html>

输出

Test 1 - returned value : a,A
Test 2 - returned value : a
