javascript - 检查 JSON 文件内数组中的值

Question

我有一个 JSON 文件，我为其创建了一个 jQuery 函数来查找匹配值并将其显示在 div 中。我不太确定如何比较 JSON 文件中的 activities 数组中的单个值。它似乎只返回整个数组。

如何检查 JSON 文件中的每个 resort 并查看 JSON 文件内的 activities 数组中的值之一是否包含特定值，例如 水肺潜水

JavaScript:

var destination = $('option:selected', "#destination").attr('value');
var comfortLevel = $('option:selected', "#comfortLevel").attr('value');
var activities = $('option:selected', "#activities").attr('value');
var date = $('option:selected', "#date").attr('value');
var price = $('option:selected', "#price").attr('value');

$.getJSON('resort.json', function(data) {
    $.each(data.resorts, function(key, val) {
        if (destination == val.destination) {
            if (comfortLevel == val.comfortLevel || activties == val.activities || date == val.startDate || price > val.price) {
                $("#resortData").html("<img src= "+val.picture+" class='miniPic'> Destination: "+ val.destination + "<br>" + "Name: " + val.name + "<br>" +"Location: " 
                + val.location + "<br>" + "Comfort: " + val.comfortLevel + " Star <br>" + "Activities: " + val.activities + "<br>" + "Price: £" 
                + val.price + "<br>" + "Start Date: " + val.startDate + "<br>" + "End Date: " + val.endDate + "<br>" + "Description: " + val.short_description 
                + "<br><br>" + "<a href=':" + val.url +"'>Click HERE for more info</a>");
            }
        }
    });
});

Answer 1

How do I check through each resortin the JSON file and see if one of the values in the activities array inside the JSON file contains a specific value like scuba diving

在事件数组上使用indexOf()。

注意这里有一个拼写错误(activties):if (comfortLevel == val.comfortLevel || activties == val.activities ...
