How to add filter on a dynamically generated object strings values

问题

Sure, here's the translated code part:

  1. 我刚开始学编程，我有一个动态生成的对象数据如下：
  3. data: {
  4.     1-leadTimeNormal: 10
  5.     3-leadTimeNormal: 22
  6.     2-leadTimeNormal: 10
  7.     2-leadTimeOptimal: 2
  8.     3-leadTimeOptimal: 22
  9.     1-leadTimeOptimal: 7
  10. }
  11. 其中，左侧的整数值（1、3、2等）是动态生成的。
  12. 现在，我想要添加一个条件来检查1-leadTimeNormal是否小于1-leadTimeOptimal（使用if Else），以及2-leadTimeNormal是否小于2-leadTimeOptimal等等，并在控制台中使用JavaScript返回一些字符串。

I've translated the code portion for you.

英文:

I am new to coding, and I have a dynamically generated Object data as this:

  1. data: {
  2.     1-leadTimeNormal: 10
  3.     3-leadTimeNormal: 22
  4.     2-leadTimeNormal: 10
  5.     2-leadTimeOptimal: 2
  6.     3-leadTimeOptimal: 22
  7.     1-leadTimeOptimal: 7
  8. }

Where, the integer value on the left hand side(1,3,2, etc) is getting generated dynamically.
Now, I want to put a condition to check whether 1-leadTimeNormal is less than 1-leadTimeOptimal or not (using if Else) and 2-leadTimeNormal is less than 2-leadTimeOptimal or not and so on and return some string in console log using javascript

你可以循环遍历从1到键的数量除以2的每个值。

  1. data = {
  2.     '1-leadTimeNormal': 10,
  3.     '3-leadTimeNormal': 22,
  4.     '2-leadTimeNormal': 10,
  5.     '2-leadTimeOptimal': 2,
  6.     '3-leadTimeOptimal': 22,
  7.     '1-leadTimeOptimal': 7
  8. }
  9. let arr = Object.keys(data)
  11. for(let i=1; i<=arr.length/2; i++) {
  12.     if(data[`${i}-leadTimeNormal`] < data[`${i}-leadTimeOptimal`]) {
  13.         console.log('hello world')
  14.     } else {
  15.         console.log('bye world')
  16.     }
  17. }

如果你不知道附加的数字，你可以将它们过滤掉。

  1. data = {
  2.     '1-leadTimeNormal': 10,
  3.     '3-leadTimeNormal': 22,
  4.     '2-leadTimeNormal': 10,
  5.     '2-leadTimeOptimal': 2,
  6.     '3-leadTimeOptimal': 22,
  7.     '1-leadTimeOptimal': 7
  8. }
  9. let keys = Object.keys(data).filter(key => key.includes('leadTimeNormal'))
  11. keys.forEach(key => {
  12.     let num = key.replace(/^([0-9]+)-.*/, '$1')
  13.     if (data[key] < data[`${num}-leadTimeOptimal`]) {
  14.         console.log('hello world')
  15.     } else {
  16.         console.log('bye world')
  17.     }
  18. });
英文:

You can loop through each value from 1 to number of keys/2

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

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

  1. data = {
  2. 	&#39;1-leadTimeNormal&#39;: 10,
  3. 	&#39;3-leadTimeNormal&#39;: 22,
  4. 	&#39;2-leadTimeNormal&#39;: 10,
  5. 	&#39;2-leadTimeOptimal&#39;: 2,
  6. 	&#39;3-leadTimeOptimal&#39;: 22,
  7. 	&#39;1-leadTimeOptimal&#39;: 7
  8. }
  9. let arr = Object.keys(data)
  11. for(let i=1; i&lt;=arr.length/2; i++) {
  12. 	if(data[`${i}-leadTimeNormal`] &lt; data[`${i}-leadTimeOptimal`]) {
  13. 		console.log(&#39;hello world&#39;)
  14. 	} else {
  15. 		console.log(&#39;bye world&#39;)
  16. 	}
  17. }

<!-- end snippet -->
If you dont know the appended numbers, you can filter them out
<!-- begin snippet: js hide: false console: true babel: false -->

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

  1. data = {
  2. 	&#39;1-leadTimeNormal&#39;: 10,
  3. 	&#39;3-leadTimeNormal&#39;: 22,
  4. 	&#39;2-leadTimeNormal&#39;: 10,
  5. 	&#39;2-leadTimeOptimal&#39;: 2,
  6. 	&#39;3-leadTimeOptimal&#39;: 22,
  7. 	&#39;1-leadTimeOptimal&#39;: 7
  8. }
  9. let keys = Object.keys(data).filter(key =&gt; key.includes(&#39;leadTimeNormal&#39;))
  11. keys.forEach(key =&gt; {
  12. 	let num = key.replace(/^([0-9]+)-.*/, &#39;$1&#39;)
  13. 	if (data[key] &lt; data[`${num}-leadTimeOptimal`]) {
  14. 		console.log(&#39;hello world&#39;)
  15. 	} else {
  16. 		console.log(&#39;bye world&#39;)
  17. 	}
  18. });

You can use 模板文字 字符串作为访问您的 data 值的键

  1. const n = 1 // 可以是数字或字符串
  2. if (data[`${n}-leadTimeNormal`] &gt; data[`${n}-leadTimeOptimal`]) {
  3.     // ....
  4. }
英文:

You can use template literal string as key to access your data value

  1. const n = 1 // may be a number or string
  2. if (data[`${n}-leadTimeNormal`] &gt; data[`${n}-leadTimeOptimal`]) {
  3.     // ....
  4. }

  13.   // ensure key is in the form "x-leadTimeNormal"
  14.   if (key.match(/\d+-.+Normal/)) {

  16.     let number = key.substring(0, key.indexOf("-"))
  17.     // test inferiority
  18.     if (data[number + "-leadTimeNormal"] < data[number + "-leadTimeOptimal"]) {
  19.       console.log("log here for number " + number)
  20.     }
  21.   }

以下是您提供的代码的翻译部分：

  1. const data = {
  2.   '1-leadTimeNormal': 10,
  3.   '3-leadTimeNormal': 22,
  4.   '2-leadTimeNormal': 10,
  5.   '2-leadTimeOptimal': 2,
  6.   '3-leadTimeOptimal': 22,
  7.   '1-leadTimeOptimal': 7
  8. }
  9. const arr = Object.keys(data);
  10. const leadTimeNormals = arr.filter(i => i.includes("leadTimeNormal"));
  12. leadTimeNormals.forEach(item => {
  13.   const [number,] = item.split("-");
  14.   if (arr[item] < arr[`${number}-leadTimeOptimal`]) {
  15.     console.log("It is here");
  16.   } else {
  17.     console.log("it is not here");
  18.   }
  19. });

请注意，我已经忽略了注释部分，只提供了代码的翻译。

英文:

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

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

  1. const data = {
  2. 	&#39;1-leadTimeNormal&#39;: 10,
  3. 	&#39;3-leadTimeNormal&#39;: 22,
  4. 	&#39;2-leadTimeNormal&#39;: 10,
  5. 	&#39;2-leadTimeOptimal&#39;: 2,
  6. 	&#39;3-leadTimeOptimal&#39;: 22,
  7. 	&#39;1-leadTimeOptimal&#39;: 7
  8. }
  9. const arr = Object.keys(data);
  10. const leadTimeNormals = arr.filter(i =&gt; i.includes(&quot;leadTimeNormal&quot;));
  12. leadTimeNormals.forEach(item =&gt; {
  13.   const [number,] = item.split(&quot;-&quot;);
  14.   if(arr[item] &lt; arr[`${number}-leadTimeOptimal`]) {
  15.     console.log(&quot;It is here&quot;);
  16.   } else {
  17.     console.log(&quot;it is not here&quot;);
  18.   }
  19. });
