Element Dialog对话框的使用示例

组件— 对话框

基本用法

<el-button type="text" @click="dialogVisible = true">点击打开 Dialog</el-button>

<el-dialog
 title="提示"
 :visible.sync="dialogVisible"
 width="30%"
 :before-close="handleClose">
 <span>这是一段信息</span>
 <span slot="footer" class="dialog-footer">
  <el-button @click="dialogVisible = false">取 消</el-button>
  <el-button type="primary" @click="dialogVisible = false">确 定</el-button>
 </span>
</el-dialog>

<script>
 export default {
  data() {
   return {
    dialogVisible: false
   };
  },
  methods: {
   handleClose(done) {
    this.$confirm('确认关闭？')
     .then(_ => {
      done();
     })
     .catch(_ => {});
   }
  }
 };
</script>

自定义内容

<!-- Table -->
<el-button type="text" @click="dialogTableVisible = true">打开嵌套表格的 Dialog</el-button>

<el-dialog title="收货地址" :visible.sync="dialogTableVisible">
 <el-table :data="gridData">
  <el-table-column property="date" label="日期" width="150"></el-table-column>
  <el-table-column property="name" label="姓名" width="200"></el-table-column>
  <el-table-column property="address" label="地址"></el-table-column>
 </el-table>
</el-dialog>

<!-- Form -->
<el-button type="text" @click="dialogFormVisible = true">打开嵌套表单的 Dialog</el-button>

<el-dialog title="收货地址" :visible.sync="dialogFormVisible">
 <el-form :model="form">
  <el-form-item label="活动名称" :label-width="formLabelWidth">
   <el-input v-model="form.name" autocomplete="off"></el-input>
  </el-form-item>
  <el-form-item label="活动区域" :label-width="formLabelWidth">
   <el-select v-model="form.region" placeholder="请选择活动区域">
    <el-option label="区域一" value="shanghai"></el-option>
    <el-option label="区域二" value="beijing"></el-option>
   </el-select>
  </el-form-item>
 </el-form>
 <div slot="footer" class="dialog-footer">
  <el-button @click="dialogFormVisible = false">取 消</el-button>
  <el-button type="primary" @click="dialogFormVisible = false">确 定</el-button>
 </div>
</el-dialog>

<script>
 export default {
  data() {
   return {
    gridData: [{
     date: '2016-05-02',
     name: '王小虎',
     address: '上海市普陀区金沙江路 1518 弄'
    }, {
     date: '2016-05-04',
     name: '王小虎',
     address: '上海市普陀区金沙江路 1518 弄'
    }, {
     date: '2016-05-01',
     name: '王小虎',
     address: '上海市普陀区金沙江路 1518 弄'
    }, {
     date: '2016-05-03',
     name: '王小虎',
     address: '上海市普陀区金沙江路 1518 弄'
    }],
    dialogTableVisible: false,
    dialogFormVisible: false,
    form: {
     name: '',
     region: '',
     date1: '',
     date2: '',
     delivery: false,
     type: [],
     resource: '',
     desc: ''
    },
    formLabelWidth: '120px'
   };
  }
 };
</script>

嵌套的 Dialog

<template>
 <el-button type="text" @click="outerVisible = true">点击打开外层 Dialog</el-button>
 
 <el-dialog title="外层 Dialog" :visible.sync="outerVisible">
  <el-dialog
   width="30%"
   title="内层 Dialog"
   :visible.sync="innerVisible"
   append-to-body>
  </el-dialog>
  <div slot="footer" class="dialog-footer">
   <el-button @click="outerVisible = false">取 消</el-button>
   <el-button type="primary" @click="innerVisible = true">打开内层 Dialog</el-button>
  </div>
 </el-dialog>
</template>

<script>
 export default {
  data() {
   return {
    outerVisible: false,
    innerVisible: false
   };
  }
 }
</script>

居中布局

<template>
 <el-button type="text" @click="outerVisible = true">点击打开外层 Dialog</el-button>
 
 <el-dialog title="外层 Dialog" :visible.sync="outerVisible">
  <el-dialog
   width="30%"
   title="内层 Dialog"
   :visible.sync="innerVisible"
   append-to-body>
  </el-dialog>
  <div slot="footer" class="dialog-footer">
   <el-button @click="outerVisible = false">取 消</el-button>
   <el-button type="primary" @click="innerVisible = true">打开内层 Dialog</el-button>
  </div>
 </el-dialog>
</template>

<script>
 export default {
  data() {
   return {
    outerVisible: false,
    innerVisible: false
   };
  }
 }
</script>

Element 对话框简单使用

官方文档介绍的是页内对话框，但没有基于组件的对话框，这里记录一下，原理就是父子传值是否显示

父页导入组件

<template>
  <div class="home">
    <el-button @click="btnAdd">添加用户</el-button>
    <Dialog :visible.sync="visible" title="添加用户"></Dialog>
  </div>
</template>

<script>
  import Dialog from "../components/dialog";

  export default {
    name: 'Home',
    components: {
      Dialog
    },
    data() {
      return {
        visible: false
      }
    },
    methods: {
      btnAdd() {
        this.visible = true
      }
    }
  }
</script>

对话框

<template>
  <div>
    <el-dialog
        v-bind="$attrs"
        v-on="$listeners"
        @open="onOpen"
        @close="onClose"
        :title="title"
        对话框打开后是否可以点击后边灰色区域关闭对话框
        :close-on-click-modal='false'>
      <el-row :gutter="15">
        <el-form ref="elForm" :model="formData" :rules="rules" size="medium" label-width="100px">
          <el-col :span="23">
            <el-form-item label="姓名" prop="userName">
              <el-input v-model="formData.userName" placeholder="请输入姓名" :maxlength="50" clearable
                   prefix-icon='el-icon-user-solid' :style="{width: '100%'}"></el-input>
            </el-form-item>
          </el-col>
          <el-col :span="23">
            <el-form-item label="性别" prop="sex">
              <el-radio-group v-model="formData.sex" size="medium">
                <el-radio v-for="(item, index) in sexOptions" :key="index" :label="item.value"
                     :disabled="item.disabled">{{item.label}}
                </el-radio>
              </el-radio-group>
            </el-form-item>
          </el-col>
          <el-col :span="23">
            <el-form-item label="生日" prop="birthday">
              <el-date-picker v-model="formData.birthday" format="yyyy-MM-dd" value-format="yyyy-MM-dd"
                      :style="{width: '100%'}" placeholder="请选择生日" clearable></el-date-picker>
            </el-form-item>
          </el-col>
        </el-form>
      </el-row>
      <div slot="footer">
        <el-button @click="close">取消</el-button>
        <el-button type="primary" @click="handelConfirm">确定</el-button>
      </div>
    </el-dialog>
  </div>
</template>

<script>
  export default {
    inheritAttrs: false,
    props: {
      title: String
    },
    data() {
      return {
        formData: {
          userName: undefined,
          sex: 3,
          birthday: null,
        },
        rules: {
          userName: [{
            required: true,
            message: '请输入姓名',
            trigger: 'blur'
          }],
          sex: [{
            required: true,
            message: '性别不能为空',
            trigger: 'change'
          }],
          birthday: [{
            required: true,
            message: '请选择生日',
            trigger: 'change'
          }],
        },
        sexOptions: [{
          "label": "男",
          "value": 1
        }, {
          "label": "女",
          "value": 2
        }, {
          "label": "保密",
          "value": 3
        }],
      }
    },
    methods: {
      onOpen() {
        //打开对话框执行
      },
      onClose() {
        //关闭对话框执行清除以上字段内容
        this.$refs['elForm'].resetFields()
      },
      close() {
        //手工调用关闭，显示状态为隐藏
        this.$emit('update:visible', false)
      },
      handelConfirm() {
        this.$refs['elForm'].validate(valid => {
          if (valid) {
            //点击确定后执行验证并执行方法,执行完毕后调用close()方法
            this.$message.success({
              message: "成功了"
            })
            this.close()
          }
        })
      }
    }
  }
