如何使用把手访问JSON对象中的Array元素

Question

 var express = require('express'); var router = express.Router(); var data = { curreny :{ name:'United States dollars', abbrev:'USD' }, tours:[ {name: 'Hood River' , price:'100'}, {name: 'Sri lanka' , price:'150'}, {name: 'Hood River' , price:'178'} ], specialsUrl:'/january-specials' } router.get('/detour',function(req,res){ res.render('tours',{object:data}); }) module.exports = router; 

Above is the code I used to export JSON object into handlebars. I need to access tour details in the tour array in a handlebars file. How can I access those details to make a list of tour details inside h3 tag. Following is the sample tour.handlebars file. Thanks in advance.

 <h2> Hello this is the body section</h2> <h3>currency : {{object.curreny.name}}</h3> <h3>tours : {{object.tours.body}}</h3> 

Answer 1

You can iterate over your tours array and then use it in handlebars like this:

{{#each object.tours}}
    <h3>name: {{name}} </h3>
    <h3>price: {{price}} </h3>
{{/each}}

Answer 2

If you are passing data in the template then you can iterate like this:

{{#each tours}}
   <h3>name :{{name}}</h3>
{{/each}}
