使用Dialog组件1

• 常规使用
  

<template>
  <div>
    Dashboard 使用visible {{ visible }}
    <Dialog
      :visible="visible"
      @changeDialog="changeDialog"
      @comfirmBtn="comfirmBtn"
    >
      <div slot="content" class="apply-wrap">
        我是content
        <el-select v-model="value" placeholder="请选择">
          <el-option
            v-for="item in options"
            :key="item.value"
            :label="item.label"
            :value="item.value"
          >
          </el-option>
        </el-select>
      </div>
    </Dialog>
    <el-button @click="btn1">按钮</el-button>
  </div>
</template>

<script>
import Dialog from "./child/Dialog.vue";
export default {
  name: "Dashboard",
  components: {
    Dialog,
  },
  data() {
    return {
      visible: false,
      options: [
        {
          value: "选项1",
          label: "黄金糕",
        },
        {
          value: "选项2",
          label: "双皮奶",
        },
        {
          value: "选项3",
          label: "蚵仔煎",
        },
      ],
      value: "",
    };
  },
  methods: {
    btn1() {
      this.visible = true;
      this.resetData();
    },
    // 改变dialog状态
    changeDialog() {
      this.visible = false;
    },
    // 确定 -> 需要做提交等处理什么的 区别于取消！
    comfirmBtn(flag) {
      this.visible = flag;
    },
    // 重置表单数据
    resetData() {
      this.value = "";
    },
  },
};
</script>
<style  lang="scss" scoped>
.apply-wrap {
  height: 200px;
}
</style>

使用Dialog组件2

• 使用底部按钮插槽与title
  

<template>
  <div>
    Dashboard 使用visible {{ visible }}
    <Dialog
      :footerSlot="true"
      :visible="visible2"
      @changeDialog="changeDialog2"
			width="65%"
			title="测试之dialog"
    >
      <div slot="content">我是content</div>
      <div slot="footer">
        <el-button @click="save">保存</el-button>
      </div>
    </Dialog>
    <el-button @click="btn2">按钮2</el-button>
  </div>
</template>

<script>
import Dialog from "./child/Dialog.vue";
export default {
  name: "Dashboard",
  components: {
    Dialog,
  },
  data() {
    return {
      visible2: false,
    };
  },
  methods: {
	// 按钮2
	btn2(){
	 this.visible2 = true;
    },
	// 保存
	save() {
     this.visible2 = false;
    },
    changeDialog2() {
      this.visible2 = false;
    },
  },
};
</script>
