迭代变量 (JavaScript)

Question

I have variables experience_company_1, experience_position_1, experience_company_2, experience_position_2,....

How do I apply a for loop to these variables? What I tried:

for(let i = 1; i < 5; i++){
   console.log(experience_company_ + i)
}

but not working.

Note: These are the values of axios response.

Answer 1

First of all, you should use an array in cases like these. However, if you do want to go with your approach, you can use eval() and Template Literals .

for(let i = 1; i < 5; i++){
  exp_var = eval(`experience_company_${i}`);
  console.log(exp_var);
}

Caution: eval() is evil and is not recommended.

Answer 2

Something like this:

 var experience_company_1 = 'Company 1', experience_position_1 = 'Position 1', experience_company_2 = 'Company 2', experience_position_2 = 'Position 2'; [ experience_company_1, experience_position_1, experience_company_2, experience_position_2 ].forEach(value => { console.log(value); });

Answer 3

use a jso structure:

 var experience = { company_1: 'c-1', position_1: 'p-1', company_2: 'c-2', position_2: 'p-2', company_3: 'c-3', position_3: 'p-3', company_4: 'c-4', position_4: 'p-4', company_5: 'c-5', position_5: 'p-5' } experience.position_2 = 'something else' for(let i=1;i<6;++i) { console.log(experience['company_'+i], experience['position_'+i] ) }
