想把JS的匿名函数改为普通函数，求助如何传递参数

Question

现在有类似这样的代码

mui(document).on("tap", ".delete", function() {
    console.log('mui(document).on("tap", ".delete")');
    commentId = this.getAttribute('comment-id');
    console.log(commentId);
    deleteLetterComment(commentId);
});

我想把这里面的function提出来复用。我知道可以这么写

mui(document).on("tap", ".delete", beforeDeleteLetterComment);

function beforeDeleteLetterComment() {
    console.log('mui(document).on("tap", ".delete")');
    commentId = this.getAttribute('comment-id');
    console.log(commentId);
    deleteLetterComment(commentId);
}

然而还有一段代码需要传递参数

function beforesubmitComment(str)
{

}

我想也这样用，但是直接写mui(document).on("tap",".delete",beforesubmitComment(str));不生效

求助该怎么写。

Answer 1

mui(document).on("tap",".delete",function(){
    beforesubmitComment(str)
});

Answer 2

mui(document).on("tap",".delete",function() { beforesubmitComment(str); });

Answer 3

能想到的方法就是上面两位写的了，其他方法暂时不晓得

Answer 4

判断argument的长度，有就拿来用，没有就是默认空参
