更名词怎么多加？

Question

我可以用这个正则表达式换个词，

editor = CKEDITOR.instances.txtisi;     
var edata = editor.getData();    
var rep_text = edata.replace("INSERT INTO", "INSERT-INTO");    
editor.setData(rep_text);

但是，如何增加更多的单词，将取代，而不仅仅是一个词。我已经试过了，但我总是得到最后的答案。如this.editor = CKEDITOR.instances.txtisi；

var edata = editor.getData();
var rep_text = edata.replace("INSERT INTO", "INSERT-INTO"); // you could also 
var rep_text = edata.replace("DELETE TABLE", "DELETE-TABLE"); // you could also 
var rep_text = edata.replace("TRUNCATE TABLE", "TRUNCATE-TABLE"); // you could also use a regex in the replace 
editor.setData(rep_text);

您的代码中有一个bug。

这是固定版本

      var edata = editor.getData();
      var edata = edata.replace("INSERT INTO", "INSERT-INTO"); // you could also 
      var edata = edata.replace("DELETE TABLE", "DELETE-TABLE"); // you could also 
      var edata = edata.replace("TRUNCATE TABLE", "TRUNCATE-TABLE"); // you could also use a regex in the replace 
      editor.setData(edata);

原因是string.replace()返回一个新字符串，而旧字符串不受影响。(就像任何字符串操作一样)。因此，您需要在每次调用edata之后使用新的数据更新.replace()变量。
