用element怎么写一个弹框

以下是一个基于 Element UI 的弹框组件的示例代码：

<template>
  <el-dialog
    :visible.sync="dialogVisible"
    :title="dialogTitle"
    :width="dialogWidth"
    @close="handleClose"
  >
    <span>{{ dialogContent }}</span>
    <div slot="footer">
      <el-button @click="dialogVisible = false">取消</el-button>
      <el-button type="primary" @click="handleConfirm">确定</el-button>
    </div>
  </el-dialog>
</template>

<script>
export default {
  data() {
    return {
      dialogVisible: false,
      dialogTitle: '',
      dialogWidth: '',
      dialogContent: '',
    };
  },
  methods: {
    openDialog(title, width, content) {
      this.dialogTitle = title;
      this.dialogWidth = width;
      this.dialogContent = content;
      this.dialogVisible = true;
    },
    handleClose() {
      this.dialogVisible = false;
    },
    handleConfirm() {
      // 处理确认操作
      this.dialogVisible = false;
    },
  },
};
</script>

使用时，可以在组件中调用 `openDialog` 方法来打开弹框，例如：

<template>
  <div>
    <el-button @click="openDialog">打开弹框</el-button>
  </div>
</template>

<script>
import Dialog from './Dialog';

export default {
  components: {
    Dialog,
  },
  methods: {
    openDialog() {
      this.$refs.dialog.openDialog('弹框标题', '50%', '弹框内容');
    },
  },
};
</script>
