頁面布局
機(jī)器人樣式參考了下圖，通過css拼造型的方式進(jìn)行實現(xiàn)。部分還原了設(shè)計圖
- 頭頂部分 頭頂部分是一個圓+偽類after實現(xiàn)白點
<div class="tianxian"></div> .tianxian{ width: 35px; height: 35px; border-radius: 50%; background: #0e58cc; position: absolute; left: 0; right: 0; top: 0; margin: auto; } .tianxian::after{ content: ''; display: block; width: 5px; height: 10px; border-radius: 12px; background: #fff; position: absolute; top: 10px; left: 5px; transform: rotateZ(20deg); }

整體布局采用絕對定位布局 利用整個頭部，實現(xiàn)耳朵和眼睛的定位
<div class="head"> <div class="erduo"></div> <div class="erduo"></div> <div class="face"> <div class="eye"></div> <div class="eye"></div> </div> </div>

- 立體效果 通過box-shadow 的inset特性，通過適當(dāng)偏移x,y軸，實現(xiàn)內(nèi)陰影的立體效果
box-shadow: -5px -5px 30px 1px #0075af inset;

- 文字轉(zhuǎn)語音實現(xiàn)
基于瀏覽器提供的SpeechSynthesisUtterance Api進(jìn)行實現(xiàn)
SpeechSynthesisUtterance基本屬性
SpeechSynthesisUtterance.lang獲取并設(shè)置話語的語言SpeechSynthesisUtterance.pitch獲取并設(shè)置話語的音調(diào)(值越大越尖銳,越低越低沉)SpeechSynthesisUtterance.rate獲取并設(shè)置說話的速度(值越大語速越快,越小語速越慢)SpeechSynthesisUtterance.text獲取并設(shè)置說話時的文本SpeechSynthesisUtterance.voice獲取并設(shè)置說話的聲音SpeechSynthesisUtterance.volume獲取并設(shè)置說話的音量
SpeechSynthesisUtterance.text基本方法
speak()將對應(yīng)的實例添加到語音隊列中cancel()刪除隊列中所有的語音.如果正在播放,則直接停止pause()暫停語音resume()恢復(fù)暫停的語音
為按鈕添加點擊事件，獲取input輸入框的值，并進(jìn)行播放，添加眼睛動畫，并在播放結(jié)束的回調(diào)移除眼睛動畫
$('#btn').click(function () { let text = $('#input').val() if (text) { $('.eye').addClass('shine') } let u = new window.SpeechSynthesisUtterance() u.text = text u.lang = 'zh' u.rate = 0.7 u.onend = function () { $('.eye').removeClass('shine') } speechSynthesis.speak(u) })
