从数组中删除所有特定值

Question

i have an array called acceptedTermsPoints(), and it is outputting 0,3,3,0,0 which is fine. What i need is a way to remove all of the values equal to 0, so that the array is equal to 3, 3

I don't have any code but please use acceptedTermsPoints() in the example. Thanks! Any help is appreciated

Answer 1

使用filter

var newArray = acceptedTermsPoints().filter(e => e != 0);

Answer 2

Try This

var acceptedTermsPoints = [0,3,3,0,0];

function isGreaterThanZero(value) {
  return value > 0;
}
var NewacceptedTermsPoints = acceptedTermsPoints.filter(isGreaterThanZero);

Answer 3

Using filter with a functional approach:

function notEquals(n) {
  return function (el) {
    return el !== n;
  }
}

function removeZeros(arr) {
  return arr.filter(notEquals(0));
}

removeZeros(acceptedTermsPoints()); // [3, 3]

Answer 4

You can use Array#filter() with Boolean as callback. This filters all values not like 0 or other falsy values.

 var array = [0, 3, 3, 0, 0], result = array.filter(Boolean); document.write('<pre>' + JSON.stringify(result, 0, 4) + '</pre>');
