常用笔记: JS实现VBS当中的Replace

<script>
 //JS实现VBS当中的Replace,替换全部.方法名大写,区别于原方法,与VBS相类似.
 String.prototype.Replace = function(oldValue,newValue,isIgnore) 
 { 
     var reg = new RegExp(oldValue,(isIgnore ? 'i' : '') + "g"); 
     return this.replace(reg, newValue); 
  }
 </script>

 调用方式:

<script>
  var str1 = 'ABCABcAbcaBCaBcabCabc'.Replace('abc','ABC'); // ABCABcAbcaBCaBcabCABC
  var str2 = 'ABCABcAbcaBCaBcabCabc'.Replace('abc','ABC',true); // ABCABCABCABCABCABCABC
 </script>
