Javascript：检查数组的每个值是否包含在字符串中？

Question

I have a JS function that creates an array based on the filters the user selects (this part works fine), and then I have another function (below) which loops through this array and should return true if the value is contained in the string and false if not.

var testString = "winter casual";
var valArray = ["winter", "casual"];


function filterArray(...values){ 
  for (i=0; i<values.length; i++){
    if (testString.includes(values[i])){
      console.log(true);
    } else {
      console.log(false);
    }
  }

 filterArray(valArray);

However, I click 1 filter button to add "winter" to the values array and it returns "true", but then I click another to add casual and it returns false, even though casual is included in the string as well. I have console logged values[] to ensure that both "winter" and "casual" are in my array, and they are.

Answer 1

Replace ...values with values as the parameter:

 var testString = "winter casual"; function filterArray(values){ for (i=0; i<values.length; i++){ if (testString.includes(values[i])){ console.log(true); } else { console.log(false); } } } filterArray(['winter']); filterArray(['winter', 'casual']);

I'm not quite sure if this is what you're looking for, as your function doesn't actually return anything, but this is a fairly simple function that might be useful:

 const containsAll = (str, strs) => strs.every(s => str.includes(s)) console.log(containsAll("winter casual", ['winter'])) //=> true console.log(containsAll("winter casual", ['winter', 'casual'])) //=> true console.log(containsAll("winter casual", ['winter', 'casual', 'medium'])) //=> false
