您可以使用下面的 JavaScript：

function pageLoad() {
     var extender = $find("AutoCompleteEx"); // extender BehaviorID

     var original = Function.createDelegate(extender, extender._getTextWithInsertedWord);
     extender._getTextWithInsertedWord = function (wordToInsert) {
          var text = original(wordToInsert);
          return text + ';';
     }
}

You can use javascript below:

function pageLoad() {
     var extender = $find("AutoCompleteEx"); // extender BehaviorID

     var original = Function.createDelegate(extender, extender._getTextWithInsertedWord);
     extender._getTextWithInsertedWord = function (wordToInsert) {
          var text = original(wordToInsert);
          return text + ';';
     }
}
