This is a JSON snip that is created in WooCommerce by a plugin that adds some metadata. I cannot change the formatting of this JSON because it is generated by a plugin. The problem is that the keys and the values are added in a weird way. I am iterating through the line_items and statically referencing this data which I don't want to do, I would like to know if there is a smart way to reference for example:
"key": "_cpo_product_id",
"value": "3572",
if this was formatted correctly it would be: "_cpo_product_id": "3572" and not have "value" as a key, and it would be accessed by: foo.line_items[i]._cpo_product_id
but with this configuration I am a bit lost, I am sure there is an easy way to find the value for a specific key. I am doing this on Google app scripts, but a solution in JavaScript should suffice.
JSON snip:
"line_items": [
{
"id": 749,
"name": "Dune",
"product_id": 3572,
"variation_id": 0,
"quantity": 1,

I have a large json data that I have to parse and get object out of the following Json string. I added just top part of that large json data. I tried to parse it by
let obj = JSON.parse(this.state.data);
it doesn't work, it breaks with this msg "SyntaxError: Unexpected token L in JSON at position 0".
If I get the console.log by console.log(JSON.stringify(this.state.data, null, 2)); and try to validate output by online JSON validator, it says it is valid JSON data. Could you please tell me how can I parse it?

Your variable this.state.data is not a JSON. It's a Javascript Object, just like JSON, So, Why not just use let obj = this.state.data;
I have a data model that attempts to map all the incoming data, however I have to leave the data generic so i can add any number of meta data tags to my project. How can I either map these data fields to the Model or access these items in the array when applying grid filters.
{
"Link": "link.com",
"Title": "project",
"Description": "descript",
"State": "TN",
"Metadata": [
{
"Name": "County",
"Value": "32"
},
{
"Name": "Info",
"Value": "info"
},
{
"Name": "State",
"Value": "TN"
}
],
"XMin": "-1",
"XMax": "-1",
"YMin": "1",
"YMax": "1"
}
I think this is what you are looking for https://docs.sencha.com/extjs/4.2.1/#!/api/Ext.data.association.HasMany
There is also nice explanation about filtering on that page

"total": 69487,
"count": 10,
"per_page": 10,
"current_page": 1,

i am actually learning how to use javascript by dealing with localstorages. I am a serverside programmer, this is my 3rd day of javascript programming. Hope someone can help me here
JSON.stringify is a serialization function. The unserialize function is called JSON.parse.
In your code localStorage.setItem('all_currencies',JSON.stringify(d)); this line converts your JSON Object to String so it can store in localStorage
Now for get data back from there you have to write
var jsonStringFromLS = localStorage.getItem('all_currencies');
Now in jsonStringFromLS you have all data in string form to convert into Object pass this value into following function
console.log(JSON.parse(jsonStringFromLS));
from above line you get your data back in JSON object form so you can now process this object.
Demo
In a collection i need to set the value to one of attributes, but i cant find the way how do it
products.models[i].set({'category.name':'some_value'})
the rest api looks like this
{
"category": {
"id": 3,
"name": "Drink",
"icon": "staging/main/category/icon-drinks.png"
},
"id": 1,
"name": "Sugar54",
"dashboard": 1,
"last_buy": "2013-10-02",
"price": "102",
"buy_period": 7
},
How do i do that ?
If you have complex nested models, I suggest you take a look at BackboneRelational.
Otherwise in your case, you should be fine with
products.models[i].get('category').name = 'some_value';
supposing that category is a normal object.
