About the method of passing array parameters to the background controller in js

Below I will share with you a method of passing array parameters to the background controller using js. It has a good reference value and I hope it will be helpful to you. Let’s take a look together

Pass parameters and pass strings, so you need to convert the array into a string,

var arr=[1,23,34,5];
var str = arr.toString();

str is passed to the background, str.split(" , "); splits the string into elements.

var arr=[1,23,34,5];
var str = arr.toString();
document.write(str);
var getArr = str.split(",");
for(var i=0;i<getArr.length;i++){
 document.write(getArr[i]+"|");
}
