constructor
• new McGeStringArray(imp?
)
构造函数。
Example
ts
import { McGeStringArray } from "mxcad";
// 创建一个新的 McGeStringArray 实例
const myArray = new McGeStringArray();
// 通过传入一个对象初始化 McGeStringArray
const initialValues = { data: ["apple", "banana", "orange"] };
const myArray2 = new McGeStringArray(initialValues);
Parameters
Name | Type | Description |

Methods
append
▸ append(val
): void
添加一个值
Example
ts
import { McGeStringArray } from "mxcad";
const array = new McGeStringArray();
array.append("apple");

at
▸ at(index
, decodeFromGb2312?
): string
根据数组索引得到数据元素的值
Example
ts
import { McGeStringArray } from "mxcad";
const array = new McGeStringArray();
array.append("apple");
array.append("banana");
console.log(array.at(0)); // 输出: "apple"

Returns
string
字符串
clear
▸ clear(): void
清空数组
Example
ts
import { McGeStringArray } from "mxcad";
const array = new McGeStringArray();
array.append("apple");
array.append("banana");
array.clear();
console.log(array.length()); // 输出: 0
Returns
void
copy
▸ copy(val
): McGeStringArray
复制对象的值
Example
ts
import { McGeStringArray } from "mxcad";
const array1 = new McGeStringArray();
const array2 = new McGeStringArray();
array2.append("apple");
array2.append("banana");
// 复制 array2 的值到 array1
array1.copy(array2);
Parameters
Name | Type |
---|---|

, decodeFromGb2312?
): void
遍历数组
Example
ts
import { McGeStringArray } from "mxcad";
const array = new McGeStringArray();
array.append("apple");
array.append("banana");
array.forEach((val, index) => {
console.log(`Index ${index}: Value ${val}`);
});
// 输出:
// Index 0: Value apple
// Index 1: Value banana
