vue常用组件之confirm

一些自带的方法，比如alert，confirm等，往往由于浏览器不同而展现出不同的样式，为了统一，我们可以自己实现简单封装，下面代码是vue的一个组件，它简单实现了confirm功能。代码如下：

<!--
 *
 * 确认对话框
 * 
 * 使用方法：
 * <dialogConfirm :show-dialog="showDialog" :ok-text="'删除'" :cancel-text="'取消'" :content="'content'" v-on:confirm="confirmFn" v-on:cancel="cancelFn" :hide-confirm="false"></dialogConfirm>
 *
 * show-dialog: 是否显示对话框，布尔值  
 * ok-text: 确认按钮文字，默认为‘好’      
 * cancel-text: 取消按钮文字，默认为‘取消’
 * hideConfirm: 是否隐藏删除按钮
 * hideCancle 是否隐藏取消按钮
 * content: 对话框文字 
 * confirmFn: 确定按钮回调
 * cancelFn: 取消按钮回调

    <div class="dialog" v-if="showDialog">
        <transition name="dialog-fade">
            <div class="dialog-bg" v-if="showDialog" @click="confirmHide"></div>
        </transition>

        <transition name="dialog-show">
            <div class="dialog-box" v-if="showDialog">

                    <div class="dialog-confirm-cancel" @click="clickCancel" v-if="!hideCancle">{{cancelText || '取消'}}</div>
                    <div class="dialog-confirm-button" @click="clickConfirm" v-if="!hideConfirm">{{okText || '好'}}</div>
                </div>
            </div>
        </transition>
    </div>
