我用过编辑按钮.编辑后,我有保存和取消按钮.save按钮正在按预期工作但不是取消按钮.
如果我在尝试编辑后单击取消按钮,它应该显示以前的文本.谁能帮帮我吗

<input ng-show="item.editing" ng-model="item.name" autofocus />
<button ng-show="item.editing" ng-click="doneEditing(item)">Save</button>
<button ng-show="item.editing" ng-click="Cancel(item)">Cancel</button>
</td>
</tr>
