let arr = [5, 15, 25, 30, 35];
console.log(arr); //result [5, 15, 25, 30, 35]
let index = arr.indexOf(30);

if (index > -1) {
   arr.splice(index, 1);
}
console.log(arr); //result [5, 15, 25, 35]

ES6路。

const commentsWithoutDeletedArray = commentsArray.filter(comment => comment.Id !== commentId);

一个非常干净的解决方案工作在所有浏览器，没有任何框架是分配一个新的数组，并简单地返回它没有你想删除的项:

/**
 * @param {Array} array the original array with all items
 * @param {any} item the time you want to remove
 * @returns {Array} a new Array without the item
 */
var removeItemFromArray = function(array, item){
  /* assign a empty array */
  var tmp = [];
  /* loop over all array items */
  for(var index in array){
    if(array[index] !== item){
      /* push to temporary array if not like item */
      tmp.push(array[index]);
    }
  }
  /* return the temporary array */
  return tmp;
}

你要的是滤镜

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter

这将允许你做以下事情:

var ary = ['three', 'seven', 'eleven'];
var aryWithoutSeven = ary.filter(function(value) { return value != 'seven' });
console.log(aryWithoutSeven); // returns ['three', 'eleven']

这一点在其他地方也有注意到:https://stackoverflow.com/a/20827100/293492

这样看看:

delete this.arrayName[this.arrayName.indexOf(value)];

参考:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete

我使用了投票最多的选项，并创建了一个函数，该函数将使用另一个不需要的单词数组清理一个单词数组:

function cleanArrayOfSpecificTerms(array,unwantedTermsArray) {
  $.each(unwantedTermsArray, function( index, value ) {
    var index = array.indexOf(value);
    if (index > -1) {
      array.splice(index, 1);        
    }
  });
  return array;
}

要使用，请执行以下操作:

var notInclude = ['Not','No','First','Last','Prior','Next', 'dogs','cats'];
var splitTerms = ["call", "log", "dogs", "cats", "topic", "change", "pricing"];

cleanArrayOfSpecificTerms(splitTerms,notInclude)
