jsdoc二维数组

Question

I have an array of array of string and I can't figure out how to document that with JSDoc.

/**
@class
*/
function PostbackList() {
    /**
    @type {int}
    @default
    */
    this.TypeID = 0;
    /**
    @type {PostbackList.Field[]}
    */
    this.Fields = new Array();
    /**

    !! Issue here !!


    @type {string[][]}
    */
    this.Values = null;
}

Which results in errors.

Invalid type expression "string[][]": Expected "!", "?" or "|" but "[" found.

And I don't know if I should put ? in front of the type to indicate it can be null.

Answer 1

According to what the current maintainer of jsdoc says in this issue report , as we speak jsdoc 3 cannot handle declaring multidimensional arrays by adding square brackets. You can do it like you did with Array.<string[]> , or with Array.<Array.<string>> .

According to the issue report, version 3.3.0 will allow the notation you wanted to use.

Louis 的回答是有效的，但维护者更新了存储库，现在您提供的代码也有效：

@type {string[][]}
