如何通过其索引值删除数组的元素

Question

I need to remove a element of a array by its index value. I have the index value already I just need to splice it. The customSeriesIndexMatch is the index number that i need to remove from customSeriesSums.data

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

因此，只需使用splice方法：

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

Answer 2

查看拼接文档 。

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