_.toPairsIn()方法用於為對象創建自己的和繼承的可枚舉字符串鍵值對的數組,該對象可以由_.fromPairs()函數使用。如果對象是Map或集合,則返回其條目。
用法:
_.toPairsIn(object)
參數:此方法接受如上所述和以下描述的單個參數:
- object:此參數保存要查詢的對象。
返回值:此方法返回鍵值對數組。
範例1:
Javascript
// Requiring the lodash library
const _ = require("lodash");
function Fb() {
this.id = 2045;
this.username = 'fb_myself';
this.password = 'fb1234';
}
Fb.prototype.email = 'myself@gmail.com';
// Use of _.toPairsIn() method
console.log(_.toPairsIn(new Fb));
輸出:
[ [ 'id', 2045 ], [ 'username', 'fb_myself' ], [ 'password', 'fb1234' ], [ 'email', 'myself@gmail.com' ] ]
範例2:
Javascript
// Requiring the lodash library
const _ = require("lodash");
function Gfg() {
this.x = 1;
this.y = 2;
}
Gfg.prototype.z = 3;
// Use of _.toPairsIn() method
console.log(_.toPairsIn(new Gfg));
輸出:
[ ['x', 1], ['y', 2], ['z', 3] ]
範例3:
Javascript
// Requiring the lodash library
const _ = require("lodash");
var GfG = {
"Geek":"GFG"
}
// Use of _.toPairsIn() method
console.log(_.toPairsIn(GfG));
輸出:
[ [ 'Geek', 'GFG' ] ]
