# ionic 按鈕 按鈕是移動app不可或缺的一部分，不同風格的app，需要的不同按鈕的樣式。 默認情況下，按鈕顯示樣式為：**display: inline-block**。 ``` <button class="button"> Default </button> <button class="button button-light"> button-light </button> <button class="button button-stable"> button-stable </button> <button class="button button-positive"> button-positive </button> <button class="button button-calm"> button-calm </button> <button class="button button-balanced"> button-balanced </button> <button class="button button-energized"> button-energized </button> <button class="button button-assertive"> button-assertive </button> <button class="button button-royal"> button-royal </button> <button class="button button-dark"> button-dark </button> ``` button-block 樣式按鈕顯示為：**display: block**，它將完全填充父元素的寬度，包含了內邊距屬性padding。 ``` <button class="button button-block button-positive"> Block Button </button> ``` 使用 button-full 類，可以讓按鈕顯示完全寬度，且不包含內邊距padding。 ``` <button class="button button-full button-positive"> Full Width Block Button </button> ``` ## 不同大小的按鈕 button-large 設置為大按鈕，button-small 設置為小按鈕。 ``` <button class="button button-small button-assertive"> Small Button </button> <button class="button button-large button-positive"> Large Button </button> ``` ## 無背景按鈕 button-outline 設置背景為透明。 ``` <button class="button button-outline button-positive"> Outlined Button </button> ``` ## 無背景與邊框按鈕 button-clear 設置按鈕背景為透明，且無邊框。 ``` <button class="button button-clear button-positive"> Clear Button </button> ``` ## 圖標按鈕 我們可以在按鈕上添加圖標。 ``` <button class="button"> <i class="icon ion-loading-c"></i> Loading... </button> <button class="button icon-left ion-home">Home</button> <button class="button icon-left ion-star button-positive">Favorites</button> <a class="button icon-right ion-chevron-right button-calm">Learn More</a> <a class="button icon-left ion-chevron-left button-clear button-dark">Back</a> <button class="button icon ion-gear-a"></button> <a class="button button-icon icon ion-settings"></a> <a class="button button-outline icon-right ion-navicon button-balanced">Reorder</a> ``` ## 頭部/底部添加按鈕 頭部/底部可以添加按鈕，按鈕的樣式根據頭部/底部來設定，所以你不需要為按鈕添加額外的樣式。 ``` <div class="bar bar-header"> <button class="button icon ion-navicon"></button> <h1 class="title">Header Buttons</h1> <button class="button">Edit</button> </div> ``` button-clear 類可以設置無背景和邊框的頭部/底部按鈕。 ``` <div class="bar bar-header"> <button class="button button-icon icon ion-navicon"></button> <div class="h1 title">Header Buttons</div> <button class="button button-clear button-positive">Edit</button> </div> ``` ## 按鈕欄 我們可以使用 button-bar 類來設置按鈕欄。以下實例中，我們在頭部和內容中添加了按鈕欄。 ``` <div class="button-bar"> <a class="button">First</a> <a class="button">Second</a> <a class="button">Third</a> </div> ```
