如何从javascript变量中删除对象/数组?
You can use Array.prototype.pop()
to remove the last element of an array.
bankBranchReponse.pop();
To remove an element at a specific index, for example the 3rd element:
var index = 2; // zero based so 2 is the 3rd element
bankBranchReponse.splice(index, 1);
As for W3CSchool http://www.w3schools.com/jsref/jsref_pop.asp
You can use the .pop()
method.
var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.pop();
The result of fruits will be:
Banana,Orange,Apple
Remove another element
To remove a certain element at an index inside the array you can use the method splice
So For example
var myFish = ['angel', 'clown', 'drum', 'surgeon', 'apple'];
// removes 1 element from index 3
removed = myFish.splice(3, 1);
And the result will be
myFish is ['angel', 'clown', 'drum', 'apple']
removed is ['surgeon']
Remember that array is zero-indexed so the 3rd element is the element number 2.
