用javascript

Question

我正在获取单个字符串$scope.Obj= ["Talking Spanish,Spanish food,Spanish things,Football"];

的数组

拆分应通过观看,

我需要细分= ["Talking Spanish","Spanish food","Spanish things","Football"];

我该如何使用JavaScript？

Answer 1

您可以使用split

let arr = ["Talking Spanish,Spanish food,Spanish things,Football"];

let op = arr[0].split(',')

console.log(op)

Answer 2

您可以使用分割$ scope.Obj的第0个索引，然后将其重新分配给$ 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（分隔符，限制） 上面是分割数组的常用语法 https://medium.freecodecamp.org/how-to-make-your-react-native-app-respond-gracefully-when-the-keyboard-pops-up-7442c1535580

Answer 4

split()方法通过使用指定的分隔符字符串确定将每个字符串拆分为子字符串的方式，通过将字符串对象拆分为子字符串，将String对象拆分为字符串数组。

在下面的示例中，split()在字符串中查找空格，并返回找到的前三个拆分。

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

console.log(splits);

此脚本显示以下内容：

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