我如何修改它以使用数组中的所有项目？

Question

Here is the code in a function I'm trying to revise. This example works on a single item from an existing array named "stream":

list = [
    {
        service: 'service1',
        user: stream [0],
        template: {
            posted:HTML1 +  stream[0] + HTML2
        }
    }
],

The code originally called for manual entry for the user value so I switched to an array since I use the same value(s) elsewhere with $.each for HTML stuff).

The stream array can vary in length so I want to avoid manually writing something like this below since I suspect it would need to match the count of stream items (could be anywhere from 1 to 50 or more):

list = [
    {
        service: 'service1', 
        user: stream [0], 
        template: { 
            posted:HTML1 +  stream[0] + HTML2
        }
    }, 
    { 
        service: 'service1', 
        user: stream [1], 
        template: { 
            posted:HTML1 +  stream[1] + HTML2
        }
    } 
],

Thanks for your help and guidance!

PS This is another attempt at this question and hope it is clearer this time. Still learning.

Answer 1

I believe, you want this:

var SERVICE = 'service1';

list = jQuery.map(stream, function (item) { 
  return {
    service: SERVICE, 
    user: item, 
    template: { 
        posted:HTML1 +  item + HTML2
    }
  }; 
});

Answer 2

A solution with just javascript: see Engineer's post for a (simpler) jQuery solution

var list = [];

for (var i = 0; i < stream.length; i++) {
    list.push({
        service: 'service1',
        user: stream[i],
        template: {
            posted: HTML1 + stream[i] + HTML2
        }
    });
}

Have a look at this: http://jsfiddle.net/xHfDb/

$.map(stream, function(item, index) {
        return {
            service: 'service' + index,
            user: item,
            template: {
                posted: HTML1 + item + HTML2
            }
        }
    })
