最近在做仿微信聊天表情發送功能，所以需要展示常用的105個表情。
因為對接微信公眾號的時候，用戶聊天過程中發送的表情，微信服務器會轉成對應的代碼傳給我們的服務器，類似如下：
:/::)/::~/::B/::|/:8-)/::</::$/::X/::Z/::'(/::-|/::@/::P/::D/::O/::(/::+[囧]/::Q/::T/:,@P/:,@-D/::d/:,@o/::g/:|-)/::!/::L/::>/::,@/:,@f/::-S/:?/:,@x/:,
@@/::8/:,@!/:!!!/:xx/:bye/:wipe/:dig/:handclap/:&-(/:B-)/:<@/:@>/::-O/:>-|/:P-(/::'|/:X-)/::*/:@x/:8*/:pd/:<W>/:beer/:basketb/:oo/:coffee/:eat
/:pig/:rose/:fade/:showlove/:heart/:break/:cake/:li/:bome/:kn/:footb/:ladybug/:shit/:moon/:sun/:gift/:hug/:strong/:weak/:share/:v/:@)/:jj/:@@
/:bad/:lvu/:no/:ok/:love/:<L>/:jump/:shake/:<O>/:circle/:kotow/:turn/:skip/:&>/:#-0/:hiphot/:kiss/:<&/:oY
所以我們需要轉換成對應的表情文本
[:1:][:2:][:3:][:4:][:52:][:5:][:6:][:7:][:8:][:9:][:10:][:11:][:12:][:13:][:14:][:15:][:53:][:16:][:17:][:18:][:19:][:20:][:21:][:22:][:23:][:24:][:25:] [:26:][:27:][:28:][:29:][:30:][:31:][:32:][:33:][:34:][:35:][:59:][:36:][:37:][:38:][:39:][:54:][:40:][:41:][:42:][:43:][:44:][:45:][:46:][:47:][:48:] [:49:][:50:][:51:][:60:][:62:][:81:][:82:][:83:][:63:][:64:][:61:][:79:][:80:][:78:][:65:][:66:][:84:][:85:][:58:][:87:][:86:][:89:][:88:][:56:][:57:] [:90:][:55:][:67:][:68:][:69:][:70:][:71:][:72:][:75:][:76:][:77:][:74:][:73:][:104:][:105:][:91:][:92:][:93:][:94:][:95:][:96:][:97:][:98:][:99:] [:100:][:101:][:102:][:103:]
以上文本對應的中文含義如下：

css對應的編號如下：

之后就需要進行一系列js轉換展示了，以下是我完成后的功能：
微信端發送：
我的pc端展示結果：
這樣表情功能就完成了，是不是很簡單。
希望能幫助到有需要的朋友。
