在javascript中针对逗号分割单个数组

Question

I am getting an array of single string $scope.Obj= ["Talking Spanish,Spanish food,Spanish things,Football"];

The split should be by watching ,

I need to break it down = ["Talking Spanish","Spanish food","Spanish things","Football"];

How can I do it using javascript?

Answer 1

You can use split

 let arr = ["Talking Spanish,Spanish food,Spanish things,Football"]; let op = arr[0].split(',') console.log(op) 

Answer 2

You can split 0th index of $scope.Obj with , and reassign to $scope.Obj.

 $scope={}; $scope.Obj= ["Talking Spanish,Spanish food,Spanish things,Football"]; $scope.Obj=$scope.Obj[0].split(",") console.log($scope.Obj); 

Answer 3

str.split（separator，limit）上面是分割数组的常见语法https://medium.freecodecamp.org/how-to-make-your-react-native-app-respond-gracefully-when-the-keyboard -pops-up-7442c1535580

Answer 4

The split() method splits a String object into an array of strings by separating the string into substrings, using a specified separator string to determine where to make each split.

In the following example, split() looks for spaces in a string and returns the first 3 splits that it finds.

var myString = 'Hello World. How are you doing?';
var splits = myString.split(' ', 3);

console.log(splits);

This script displays the following:

["Hello", "World.", "How"]
