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>
