本文實例講述了JS實現數組刪除指定元素功能。分享給大家供大家參考，具體如下：
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>m.survivalescaperooms.com JS數組刪除指定元素</title></head><body><script> var array = ["111", "222", "333", "444", "555", "666"]; var indexList = [0, 5, 6]; var indexList1 = [5]; Array.prototype.del = function(indexList) { function isValidate(number) { if(isNaN(number) && number > this.length) { return false; } } if(indexList instanceof Array) { indexList.sort(function(x, y) { if(x > y) { return 1; } else { return -1; } }); var lastIndex = indexList[indexList.length - 1]; isValidate(lastIndex); for(var i = 0; i < indexList.length; i++) { var n = i; if(n > 0) { indexList[i] = indexList[i] - n; } this.splice(indexList[i], 1); n++; } } else { isValidate(indexList); this.splice(indexList, 1); } } console.log("before delete: " + array); array.del(indexList1); console.log("after delete: " + array);</script></body></html>運行結果：
希望本文所述對大家JavaScript程序設計有所幫助。
