这个封装的是一个供整个项目使用的表格,可多次复用.放在一个全局使用的公共组件文件下.
大致功能介绍,封装自定义指令,点击获得焦点,显示输入框,失去焦点显示文本内容,类型是字典决定类型,图片可以显示图片名还是上传图片
子组件
javascript
<script>
export default {
props: {
//生成表头
fields: {
type: Array,
default: () => [],
},
//数据
tableData: {
type: Array,
default: () => [],
},
},
data() {
return {};
},
created() {},
// 自定义指令
directives: {
focus: {
inserted: function (el) {
el.querySelector("input").focus();
},
},
},
methods: {
// 点击框 获取焦点 column列,row 行
cellClick(column, row) {
column.iseditor = true;
row.isnameSelected = true;
},
//输入框失去焦点触发,此处用提示框提示修改
blurEvent(column, row) {
// console.log(column, row);
column.iseditor = false;
row.isnameSelected = false;
},
},
};
</script>

这里还有封装了一个文件上传的组件嵌套在表格中,算是拓展
