Question

i am sorry if this question has been asked before I couldn't seem to find something to answer this.

Below is my Json decoded array:

cart_id:1
cart_items:
  1:
    cost:4
    name:"Titleist Pro V1"
    quantity:4
  2:
    cost:1
    name:"Titleist Pro V1x"
    quantity:1

How can i dynamically display this into html using JQuery or javascript? I have figured out to be able to display a single variable by using this:

$result['cart_items']['1']['name'];

This will give me "Titleist Pro V1" in return. I am struggling with a lot of errors from all sides and felt the code itself would be too messy to paste here. It would be amazing if somebody could please just show me how i can dynamically create this data into an ul using the next pasted format with a loop or something.

<ul>
  <li> $name x $quantity <br> cost: $cost</li>
  <li> $name x $quantity <br> cost: $cost</li>
</ul>

EDIT: I meant to show the top list bit as pure html but stackoverflow is converting it too an actual list, i hope its still understandable.

NOTE: My data is brought in from a database through laravel/php. i receive an json encoded file that i then proceed to decode with:

$result = jQuery.parseJSON(result);

I need to be able to take any amount of results and display a list of items and their costs. Sorry if this is a lot of trouble, I'm struggeling with Laravel at the moment and things feel very overwelming.

Thank you for all your help in advance!

假设您的JSON采用以下格式

$result = {
  "cart_id" : 1,
  "cart_items": {
      "1": {
        cost:4,
        name:"Titleist Pro V1",
        quantity:4
      },
      "2": {
        cost:1,
        name:"Titleist Pro V1x",
        quantity:1
      }
  }
};

您可以使用jQuery each方法循环访问对象，使用下面的代码生成<ul>

var b = "<ul>";

$.each($result['cart_items'], function(property, value) {
  b += "<li>" + value['cost'] * value['quantity'] + "<br/>" + "cost " + value['cost'] + "</li>";
});

b += "</ul>";

$(".container").html(b);
