如何从jquery中的数组中删除元素

Question

var arr = [ "alice","bob","charli","dane","elisha","furnos"]; var temp = "bob";

I want to remove bob from arr by using variable temp.

Answer 1

This is an easy one liner:

arr.splice( arr.indexOf(temp), 1 );

Looks for the variable temp in the array and removes one element at that index.

Answer 2

arr.filter((name) => name !== temp);

Answer 3

We can use Javascript array's filter method to remove the required item.

 var arr = ["alice", "bob", "charli", "dane", "elisha", "furnos"]; var temp = "bob"; var filteredArray = arr.filter(item => item !== temp); console.log(filteredArray);

OR

With Jquery we can go with grep,

var arr = ["alice", "bob", "charli", "dane", "elisha", "furnos"];
var temp = "bob";
arr = jQuery.grep(arr, function (value) {
    return value != temp;
});
console.log(arr);
