const sort = ["this","is","my","custom","order"]; const myObjects = [ {"id":1,"content":"is"}, {"id":2,"content":"my"}, {"id":3,"content":"this"}, {"id":4,"content":"custom"}, {"id":5,"content":"order"} ];
我们需要编写一个JavaScript函数,该函数接受两个这样的数组,并根据第一个数组对第二个对象数组进行排序,以使对象的content属性与第一个数组的字符串匹配。
因此,对于上述数组,输出应类似于-
const output = [ {"id":3,"content":"this"}, {"id":1,"content":"is"}, {"id":2,"content":"my"}, {"id":4,"content":"custom"}, {"id":5,"content":"order"} ];
为此的代码将是-
const arrLiteral = ["this","is","my","custom","order"]; const arrObj = [ {"id":1,"content":"is"}, {"id":2,"content":"my"}, {"id":3,"content":"this"}, {"id":4,"content":"custom"}, {"id":5,"content":"order"} ]; const sortByReference = (arrLiteral, arrObj) => { const sorted = arrLiteral.map(el => { for(let i = 0; i < arrObj.length; ++i){ if(arrObj[i].content === el){ return arrObj[i]; } }; }); return sorted; }; console.log(sortByReference(arrLiteral, arrObj));
输出结果
控制台中的输出将是-
[ { id: 3, content: 'this' }, { id: 1, content: 'is' }, { id: 2, content: 'my' }, { id: 4, content: 'custom' }, { id: 5, content: 'order' } ]
