Usage

there are some utils in this package.you can use them by import them. for example:

// this function can be used to get tree data from list data
import { arrayToTree } from 'log1997-utils'
const arrData=[
    {id:1,name:'a',pid:0},
    {id:2,name:'b',pid:1},
    {id:3,name:'c',pid:1},
    {id:4,name:'d',pid:2},
    {id:5,name:'e',pid:2},
    {id:6,name:'f',pid:3},
    {id:7,name:'g',pid:3},
    {id:8,name:'h',pid:4},
]
cosnt treeData=arrayToTree(arrData);
console.log(treeData);

ArrayFuc

arrayToTree

there are some params in this function: your arrData's item have to have idKey and pidKey.

• arrData:a array and it's necessary.
• idKey:the key of id in arrData,it's default value is 'id',not necessary.
• pidKey:the key of pid in arrData,it's default value is 'pid'.not necessary.
• childrenKey:the key of children in arrData,it's default value is 'children'.not necessary.

there are a return data:

• treeData:it's a tree data.

treeToArray

there are some params in this function:

• treeData:a tree data and it's necessary.
• childrenKey:the key of children in treeData,it's default value is 'children'.not necessary.

there are a return data:

• arrData:it's a array data.

ColorFunc

getRandomGradientColor

this function can be used to get a random gradient color string. there are some params in this function:

• hexColor:the number of hexcolor in gradient color string. like:#ffffff.not necessary.
• deg:the deg of gradient color,it's tyep is number. like:90.not necessary.
• Colorangle:the angle of gradient color,it's type is number. like:90.not necessary. there are a return data:
• color:it's a gradient color string.like:linear-gradient(90deg, #ffffff, #ffffff).

and ther are other functions in this package.

| Function | Description | | --- | --- | |rgb2Hsv|rgb to hsv| |rgb2Hsl|rgb to hsl| |rgb2Hex|rgb to hex| |hex2Rgb|hex to rgb| |hsv2Rgb|hsv to rgb| |rotateHsv|rotate hsv default angle is 30°| |randomColor|get a random color|

MathFunc

byteToUnit

this function can be used to convert byte to unit. for example,if you want to convert 1024 byte to kb, you can use this function like this:

import { byteToUnit } from 'log1997-utils'
const kb=byteToUnit(1025,'kb'); //100.10KB

params:

• byte:the number of byte.necessary.
• unit:the unit of byte.default value is ''not necessary.
• fixed:the number of fixed.default value is 2.not necessary.

return:

• unitByte:the string of unit data.
