Javascript检查对象属性是否相等

Question

I have a function that loops through an object that currently returns 5 values. The last value it returns will always be undefined.

I would like to execute some code only if all 4 value.valueId === 2

This is what I have right now

Object.values(answers['3']).forEach(value => {
    console.log('checkboxValues', value.valueId)
    if (value.valueId === 2) {
      console.log('I AM 2')
    } else {
      console.log('I AM SOMETHING ELSE')
    }
  })

How do I check if all value.valueId === 2 ?

Answer 1

Just use 'every'. Info: https://www.w3schools.com/jsref/jsref_every.asp

Object.values(answers['3']).every(value => {
    return value.valueId === 2;
})

Here is it as an if statement:

if (Object.values(answers['3']).every(v => v.valueId === 2)) {
    // do success case
}
