Javascript js simple implementation of adding, deleting, modifying and searching of arrays

Function definition

 Array.prototype.indexOf = function(val) { for (var i = 0; i < this.length; i++) { if (this[i] == val) return i; } return -1;};Array.prototype.remove = function(val) { var index = this.indexOf(val); if (index > -1) { this.splice(index, 1); }};Array.prototype.insert = function (index, item) { this.splice(index, 0, item);};

use:

myarray.remove(i); //Delete

//renew

myarray.remove(0);

myarray.insert(0,eventjson[0]);

//insert

myarray.insert(0,eventjson[0]);

The simple implementation of the above javascript js operation array addition, deletion, modification and search is all the content I share with you. I hope you can give you a reference and I hope you can support Wulin.com more.
