一、list数据结构转tree父子结构
export const translateDataToTree = (data) => {
let parents = data.filter(
value => value.parentId == "undefined" || value.parentId == 0
);
let children = data.filter(
value => value.parentId !== "undefined" && value.parentId != 0
);
let translator = (parents, children) => {
parents.forEach(parent => {
children.forEach((current, index) => {
if (current.parentId === parent.deptId) {
let temp = JSON.parse(JSON.stringify(children));
temp.splice(index, 1);
translator([current], temp);
typeof parent.children !== "undefined" ?
parent.children.push(current) :
// parent.push(current) :
(parent.children = [current]);
}
});
});
};
translator(parents, children);
return parents;
}
二、tree数据结构转list数据结构
export default function treeToArray(data, children = 'children') {
let tmp = []
data.forEach((item, index) => {
Vue.set(item, '_index', index)
tmp.push(item)
if (item[children] && item[children].length > 0) {
const res = treeToArray(item[children], children)
tmp = tmp.concat(res)
}
})
return tmp
}
三、对象深拷贝
方案一:
export const deepClone = data => {
var type = getObjType(data);
var obj;
if (type === 'array') {
obj = [];
} else if (type === 'object') {
obj = {};
} else {
//不再具有下一层次
return data;
}
if (type === 'array') {
for (var i = 0, len = data.length; i < len; i++) {
obj.push(deepClone(data[i]));
}
} else if (type === 'object') {
for (var key in data) {
obj[key] = deepClone(data[key]);
}
}
return obj;
};
方案二:
export const function deepClone(obj){
let _obj = JSON.stringify(obj),
objClone = JSON.parse(_obj);
return objClone
}
四、深度递归搜索
/**
* @param {Array} arr 你要搜索的数组
* @param {Function} condition 回调函数,必须返回谓词,判断是否找到了。会传入(item, index, level)三个参数
* @param {String} children 子数组的key
*/
const deepFind = (arr, condition, children) => {
// 即将返回的数组
let main = []
// 用try方案方便直接中止所有递归的程序
try {
// 开始轮询
(function poll(arr, level) {
// 如果传入非数组
if (!Array.isArray(arr)) return
// 遍历数组
for (let i = 0; i < arr.length; i++) {
// 获取当前项
const item = arr[i]
// 先占位预设值
main[level] = item
// 检验是否已经找到了
const isFind = condition && condition(item, i, level) || false
// 如果已经找到了
if (isFind) {
// 直接抛出错误中断所有轮询
throw Error
// 如果存在children,那么深入递归
} else if (children && item[children] && item[children].length) {
poll(item[children], level + 1)
// 如果是最后一个且没有找到值,那么通过修改数组长度来删除当前项
} else if (i === arr.length - 1) {
// 删除占位预设值
main.length = main.length - 1
}
}
})(arr, 0)
// 使用try/catch是为了中止所有轮询中的任务
} catch (err) {}
// 返回最终数组
return main
}
let myarr = deepFind(fuck, (item, index, level) => item.value === 63, 'children')
console.log(20181115092957, myarr) // [{…}, {…}, {…}]
console.log(20181115092957, myarr.map(_ => _.value)) // [32, 58, 63]
五、浏览器全屏、退出全屏
/**
* 浏览器全屏
*/
export const reqFullScreen = () => {
if (document.documentElement.requestFullScreen) {
document.documentElement.requestFullScreen();
} else if (document.documentElement.webkitRequestFullScreen) {
document.documentElement.webkitRequestFullScreen();
} else if (document.documentElement.mozRequestFullScreen) {
document.documentElement.mozRequestFullScreen();
}
};
/**
* 浏览器退出全屏
*/
export const exitFullScreen = () => {
if (document.documentElement.requestFullScreen) {
document.exitFullScreen();
} else if (document.documentElement.webkitRequestFullScreen) {
document.webkitCancelFullScreen();
} else if (document.documentElement.mozRequestFullScreen) {
document.mozCancelFullScreen();
}
};
六、根据数据字典的value查找对应的index
export const findArray = (dic, value) => {
for (let i = 0; i < dic.length; i++) {
if (dic[i].value == value) {
return i;
}
}
return -1;
};
