在对象中存储内容时,如何在文本中插入变量?

object arrays javascript

我正在使用下面的代码将内容插入页面。我需要在文本中插入一些变量来生成一些动态值,并且不确定如何执行此操作。有人能告诉我需要改变什么吗?

下面是我在JS中存储数据的精简示例:

var fruit = {
    'apples': {
        'goldenDelicious' : {
            color: 'yellow',
            sale: 'A sale of $XXXXX (need to insert a number in here). Be sure to buy some before they are all gone!',
            link: {
                linkText: ('This company sells this for $XXXXX (eed to insert a price here). Click here to visit their site.'),
                url: 'I NEED TO INSERT THE URL HERE'
            }
        }
    }
}

下面是一个我如何称呼它的例子:(它比这个更具活力,但你知道这个想法)

var fruitType = 'apples';
var fruitVariety = 'goldenDelicious';

fruit[fruitType][fruitVariety], function () {
    // do something
});

所以我希望能够在对象中插入价格、销售和URL等值。

var fruit = {
    'apples': {
        'goldenDelicious' : {
            color: 'yellow',
            sale: 'A sale of PLACEHOLDER_1. Be sure to buy some before they are all gone!',
            link: {
                linkText: ('This company sells this for PLACEHOLDER_2. Click here to visit their site.'),
                url: 'I NEED TO INSERT THE URL HERE'
            }
        }
    }
}

fruit.apples.goldenDelicious.sale = fruit.apples.goldenDelicious.sale.replace("PLACEHOLDER_1", "the real value");
