Loop through Object and push into Array

问题

我想循环遍历对象并在JavaScript中将这些对象添加到数组中。

  1. // 我的对象:
  2. var raw_data = {
  3.   name: "Mike",
  4.   age: "27",
  5. };
  7. var array_data = [];
  9. // 然后我遍历对象:
  10. for (let [key, name] of Object.entries(raw_data)) {
  11.   if (name !== "") {
  12.     array_data.push({
  13.       email: `${raw_data.name}`,
  14.       password: `${raw_data.age}`,
  15.     });
  16.   }
  17. }
  18. console.log(array_data);

我的输出是:

  1. [
  2.   { email: 'nang@gmail.com', password: '1234567' },
  3.   { email: 'nang@gmail.com', password: '1234567' }
  4. ]

我希望只得到一个插入:

  1. [
  2.   { email: 'nang@gmail.com', password: '1234567'}
  3. ]

请问如何做到这一点？

I am looking to loop the object and want to add those object in array in Javascript.

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

  1. //My Object:
  3. var raw_data = {
  4.   name: &quot;Mike&quot;,
  5.   age: &quot;27&quot;,
  6. };
  8. var array_data = [];
  10. //Then I loop through the object:
  12. for (let [key, name] of Object.entries(raw_data)) {
  13.   if (name !== &quot;&quot;) {
  14.     array_data.push({
  15.       email: `${raw_data.name}`,
  16.       password: `${raw_data.age}`,
  17.     });
  18.   }
  19. }
  20. console.log(array_data);

<!-- end snippet -->

My out put is :

  1. [
  2.   { email: &#39;nang@gmail.com&#39;, password: &#39;1234567&#39; },
  3.   { email: &#39;nang@gmail.com&#39;, password: &#39;1234567&#39; }
  4. ]

I would like expect to get only one insert:

  1. [
  2.   { email: &#39;nang@gmail.com&#39;, password: &#39;1234567&#39;}
  3. ]

Could you please help me how to get that?

我认为你想要这个，只需将一个对象推入一个数组中，并借助 map 方法循环遍历数组，用你想要的键替换你的键

  1. var raw_data = {
  2.   name: "Mike",
  3.   age: "27",
  4. };
  6. var array_data = [];
  7. array_data.push(raw_data);
  9. var new_array = array_data.map(item => {
  10.   return { email: item.name, password: item.age };
  11. });
  13. console.log(new_array);
英文:

I think you want this, just push an object into an array and with the help of map method loop through the array to replace your keys with your desired ones

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

  1. var raw_data = {
  2.   name: &quot;Mike&quot;,
  3.   age: &quot;27&quot;,
  4. };
  6. var array_data = [];
  7. array_data.push(raw_data);
  9. var new_array = array_data.map(item =&gt; {
  10.   return { email: item.name, password: item.age };
  11. });
  13. console.log(new_array);

<!-- end snippet -->
