从子对象与值匹配的数组中删除对象

Question

I'm currently attempting to sort through some values based on a query string. I'm able to target each target individually in this loop but cannot seem to properly remove them from the array. How can I remove certain values that match on target.target from targetList ?'

targetList.forEach(function(target, key) {
    var os = getParameterByName('os');

    if (os == "android") {
        if (target.target.includes(":IOS")) {
            targetList.splice(key, 1);
        }
    } else if (os == "ios") {
        if (target.target.includes(":ANDROID")) {
            targetList.splice(key, 1);
        }
    }

    if (target.target.includes(":IOS")) {
        target.target = schools[target.target.replace(":IOS", "").toLowerCase()] + " (iOS)" || target.target;
    }

    if (target.target.includes(":ANDROID")) {
        target.target = schools[target.target.replace(":ANDROID", "").toLowerCase()] + " (Android)" || target.target;
    }

});

targetList contains an array like this:

[
  {
    "target": "t1",
    "datapoints": [
      [
        51.0,
        1483574400.0
      ],
      [
        54.0,
        1485561600.0
      ],
      [
        54.0,
        1485648000.0
      ]
    ]
  },
  {
    "target": "t2",
    "datapoints": [
      [
        56.0,
        1484265600.0
      ],
      [
        70.0,
        1484352000.0
      ],
      [
        71.0,
        1484438400.0
      ],
      [
        51.0,
        1484611200.0
      ]
    ]
  },
]

What I'm attempting to do is that where a target matches certain criteria .includes() I want to remove the entire containing object/array.

It seems to me your code works just fine. I've created a snippet where I removed the extra processing, to show that what you have already does what you ask.

Is there a reason you're doing stuff to target.target once you've removed it from the array? Do you have a reference to the containing object somewhere else?

 var targetList = [ { "target": "t1", "datapoints": [ [ 51.0, 1483574400.0 ], [ 54.0, 1485561600.0 ], [ 54.0, 1485648000.0 ] ] }, { "target": "t2", "datapoints": [ [ 56.0, 1484265600.0 ], [ 70.0, 1484352000.0 ], [ 71.0, 1484438400.0 ], [ 51.0, 1484611200.0 ] ] }, ]; targetList.forEach(function(target, key) { if (target.target.includes("t2")) { targetList.splice(key, 1); } }); console.log(targetList);
