MUI-button（按鈕），載入中按鈕
阿新 • • 發佈：2018-12-28
當用戶點選按鈕後，需要向服務端提交資料或等待服務端響應時，常常需要提示“正在提交”，並將按鈕設定為disabled，避免使用者重複點選、重複提交；載入中按鈕支援修改 loading狀態的文案、顯示的icon和icon的位置,如下:
| 屬性名 | 作用 |
|---|---|
data-loading-text |
loading 狀態顯示的文案,預設為: loading |
data-loading-icon |
loading 狀態顯示的icon,預設為mui-spinner或mui-spinner mui-spinner-white |
data-loading-icon-position |
loading 狀態顯示的icon的位置,支援left/right，預設left |
1、預設，左側loading圖示：
<button type="button" class="mui-btn mui-btn-primary">確認</button>
2、 右側loading圖示，增加data-loading-icon-position="right"：
<button type="button" class="mui-btn mui-btn-primary" data-loading-text="提交中" data-loading-icon-position="right">確認</button>
3、 無loading圖示，增加data-loading-icon=""：
<button type="button" class="mui-btn mui-btn-primary" data-loading-icon="">確認</button>
4、自定義loading圖示，增加data-loading-text、data-loading-icon、 data-loading-icon-position三個屬性的設定：
<button type="button" class="mui-btn mui-btn-primary" data-loading-text="提交中" data-loading-icon="mui-spinner mui-spinner-custom" data-loading-icon-position="right">確認</button>
5、觸發事件，JS如下：
mui(document.body).on('tap', '.mui-btn', function(e) {
mui(this).button('loading');//切換為loading狀態
setTimeout(function() {
mui(this).button('reset');//切換為reset狀態(即重置為原始的button)
}.bind(this), 2000);
});6、全部狀態展示效果：

mui的載入中按鈕就實現了類似效果，點選如下按鈕體驗：</p>
