Javascript排序按字母顺序匹配字符串的开头，然后按字母顺序匹配包含的文本 [英] Javascript sort alphabetically matching the beginning of string then alphabetically for contained text

问题描述

我需要一些整理数据的帮助. 假设我在搜索栏中输入"piz".我得到返回并包含所有包含"piz"的条目的数组.

I need help sorting through some data. Say I type "piz" in a searchfield. I get in return and array with all the entries that contain "piz".

我现在要按以下顺序显示它们:

I now want to display them in the following order:

pizza 
pizzeria
apizzetto
berpizzo

首先以我按字母顺序键入的内容开头的项，然后是包含我按字母顺序键入的内容的项.

First the items that start with what I typed in alphabetical order then the ones that contain what I typed in alphabetical order.

相反，如果我按字母顺序对它们进行排序，则会得到以下内容

Instead if I sort them alphabetically I get the following

apizzetto
berpizzo
pizza 
pizzeria

有人知道该怎么做吗? 谢谢你的帮助.

Does anyone know how to do this? Thanks for your help.

推荐答案

您可以将数据拆分为两个数组，一个数组以您的输入开头，另一个数组不以您的输入开头.分别对它们进行排序，然后合并两个结果:

You can split the data into two arrays, one that starts with your input and one that doesn't. Sort each separately, then combine the two results:

var data = [
    'pizzeria',
    'berpizzo',
    'apizzetto',
    'pizza'
];

function sortInputFirst(input, data) {
    var first = [];
    var others = [];
    for (var i = 0; i < data.length; i++) {
        if (data[i].indexOf(input) == 0) {
            first.push(data[i]);
        } else {
            others.push(data[i]);
        }
    }
    first.sort();
    others.sort();
    return(first.concat(others));
}

var results = sortInputFirst('piz', data);
