只需要在:width后面加上.sync即可实现动态修改Dialog宽度
<el-button type="text" @click="dialogVisible = true">点击打开 Dialog</el-button>
<el-dialog
title="提示"
:visible.sync="dialogVisible"
:width.sync="dialogWidth">
<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,
dialogWidth:"30%"
};
},
};
</script>
