接上一节,今天讲动态更新数据的方法
1、后端动态更新代码如下:
/**
* 根据主表名,关键字和数据动态更新一条记录
* @param tableName 主表名称
*/
@SaCheckPermission("workflow:form:edit")
@PostMapping(value = "/updateDataById")
public R<?> updateDataById(@RequestBody FormDataVo formDataVo) {
return R.ok(formService.updateDataById(formDataVo));
}
@Override
public int updateDataById(FormDataVo formDataVo) {
return baseMapper.updateDataById(formDataVo.getTableName(), formDataVo.getPrimaryKey(),Long.valueOf(formDataVo.getId()),formDataVo.getUpdateMap());
}
int updateDataById(@Param("tableName") String tableName, @Param("primaryKey") String primaryKey,
@Param("id") Long id, @Param("updateMap") Map<String,Object> updateMap);
<update id="updateDataById">
UPDATE ${tableName} SET
<foreach collection="updateMap" item="val" index="key" separator=",">
${key} = #{val}
</foreach>
WHERE ${primaryKey} = #{id}
</update>
2、前端代码如下:
/** 提交按钮 */
submitForm() {
this.$refs["form"].validate(valid => {
if (valid) {
this.buttonLoading = true;
console.log("submitForm this.form",this.form)
const id = this.form[this.primaryKey] || this.ids
const formData = {
tableName: this.tableName,
primaryKey: this.primaryKey,
id: id,
updateMap: this.form
}
console.log("submitForm formData",formData)
if (id != null) {
updateDataById(formData).then(response => {
this.$modal.msgSuccess("修改成功");
this.open = false;
this.getList();
}).finally(() => {
this.buttonLoading = false;
});
}
}
});
},
3、效果图如下:
