JS实现数组删除指定元素功能示例
人气:0本文实例讲述了JS实现数组删除指定元素功能。分享给大家供大家参考,具体如下:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>www.qb5200.com JS数组删除指定元素</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>
运行结果:
希望本文所述对大家JavaScript程序设计有所帮助。
