如何通过索引值删除数组元素

Question

我需要通过索引值删除数组元素。我有索引值，我只需要拼接它。 customSeriesIndexMatch是我需要从customSeriesSums.data

中删除的索引号

fiddle

var dataPointSum = 101100;
console.log(customSeriesSums[0].data);

 // loop through customSeriesSums and match with dataPointSum
    var index = customSeriesSums[0].data.indexOf(dataPointSum);
    var customSeriesIndexMatch = index + 1
   console.log("DataPointSum : " + dataPointSum + " " + "Matched with customSeriesSum Index : " + customSeriesIndexMatch);

 // now I need to remove the customSeriesSums.data array by its index that equals customSeriesIndexMatch

Answer 1

所以只需使用splice方法：

customSeriesSums[0].data.splice( customSeriesIndexMatch, 1 );

Answer 2

查看splice docs。

customSeriesSums[0].data.splice( customSeriesIndexMatch,1 );
