如何检查字符串是否是数组中任何元素的子字符串 [英] How to check if a string is a substring of any element in an array

问题描述

我有一个数组

var months = ["January", "February", "March", "April", \
    "May", "June", "July", "August", "September", "October", \
    "November", "December"];

我有"Nov"，"October"，"Jun"，"June"，"Sept"，"Sep"等字符串.要点是，该字符串可以是一个月中的一个子字符串.

I have strings like "Nov", "October", "Jun", "June", "Sept", "Sep" etc. The point is, the string can be a substring of one of the months.

将字符串比较为数组元素的子字符串的最佳方法是什么?如何查找月份索引?

What is the best way to compare the string to be a substring of the array elements? How do I find out the index of the month?

我正在查看javascript/jQuery.

I am looking at javascript/jQuery.

我知道我可以使用search遍历数组检查每个元素，并在找到时中断.我想要更好的东西.

I know I can just loop through the array checking against each element using search and break when found. I want something better.

推荐答案

var month_index = function(target) {
        target = target.toLocaleLowerCase();
        return jQuery.inArray(true, jQuery.map(months, function(s) {
            return s.toLocaleLowerCase().indexOf(target) > -1;
        }))
    };

var index_of_october = month_index("oct");
