網(wǎng)上有很多關(guān)于pos機(jī)上如何輸字母,python獲取中文的拼音首字母的知識(shí)，也有很多人為大家解答關(guān)于pos機(jī)上如何輸字母的問(wèn)題，今天pos機(jī)之家(www.afbey.com)為大家整理了關(guān)于這方面的知識(shí)，讓我們一起來(lái)看下吧!

pos機(jī)上如何輸字母

最近需要實(shí)現(xiàn)拼音首字母搜索，順便整理一下其他語(yǔ)言的拼音首字母搜索的代碼進(jìn)行備用，有需要的直接拿走。話不多說(shuō)，直接上碼

JavaScript，只保留了核心的提取拼音的部分，如果需要可以留下郵箱或者私信我

第一種:

直接上代碼(有個(gè)別中文無(wú)法識(shí)別):
