建议字段无法正常工作-AS3 AIR代码

问题描述

我的应用程序中有一个建议字段。到目前为止，该代码是有效的（或者我认为是可行的）。 它链接到txt文件。文本文件中的每个句子都用＃分隔； @H_502_1@

示例：@H_502_1@

嗨，你好吗？＃干得好＃@H_502_1@

我有175个句子​​。@H_502_1@

奇怪的是，如果我为“ Non”输入“ N”，则该代码有效，并建议我每个字母为N的句子@H_502_1@

Every sentences with "N" is suggested @H_502_1@

但是，如果我输入“否”，则不再建议使用“无”！@H_502_1@

"Non" is not here @H_502_1@

它用很多句子来做到这一点。...@H_502_1@

这是我的代码：@H_502_1@

function checkKeypress(event: KeyboardEvent): void {
                    if (event.keyCode == Keyboard.BACK) {

        }

任何想法可能是什么问题吗？@H_502_1@

解决方法

在检查每个建议中是否存在小写输入时，您没有将suggestions标准化为小写。因此，第一次选择时，“ Non”对结尾的“ n”有反应，但是“ Non”不包含“ no”，因此在第二种情况下不会显示。因此，创建suggestions_lower数组，用小写的建议填充它，然后在用原始建议填充文本字段时进行检查。
