如何根据值来分隔字符串

var str = "apple,banana,orange";
var arr = str.split(",");
console.log(arr); // 输出：["apple", "banana", "orange"]

var str = "apple,banana;orange";
var arr = str.split(/[,;]/);
console.log(arr); // 输出：["apple", "banana", "orange"]

var str = "name:John;age:25";
var arr = [];
var index = 0;
while (index < str.length) {
  var colonIndex = str.indexOf(":", index);
  var semicolonIndex = str.indexOf(";", index);
  if (colonIndex !== -1 && (colonIndex < semicolonIndex || semicolonIndex === -1)) {
    var value = str.substring(index, colonIndex);
    arr.push(value);
    index = colonIndex + 1;
  } else if (semicolonIndex !== -1 && (semicolonIndex < colonIndex || colonIndex === -1)) {
    var value = str.substring(index, semicolonIndex);
    arr.push(value);
    index = semicolonIndex + 1;
  } else {
    break;
  }
}
console.log(arr); // 输出：["name", "John", "age", "25"]
