I have a form that aggroup the data on classes class_a[name], class_a[description] , class_b[name], class_b[description], etc. On nodejs, using body parser, the output of req.body is
class_a[name]: "name of class a"
class_a[description] : "description of class a"
class_b[name]: "name of class b"
class_b[description] : "description of class b"
and so on.
But i cant get as an object, i.e. i cant do get the value like "class_a.name" or "class_b.description". How to do this ?
To use the shape as if it was an Array, you can create a previous shape and update with the values you are receiving. Try to take a look at how to update Array - https://developer.mozilla.org/pt-BR/docs/Web/JavaScript/Reference/Global_Objects/Array/observe
You need send data in the following format:
{
class_a: {
name: "name of class a",
description: "description of class a"
},
class_b: {
name: "name of class b",
description: "description of class b"
}
}
I think this is what you need.
class_a["name"]: "name of class a"
class_a["description"] : "description of class a"
class_b["name"]: "name of class b"
class_b["description"] : "description of class b"
You can map data in frontend in the following format, I guess that would be easy for you to iterate on it on node JS side:
const classData = [{
className: "a",
name: "name of class a",
description: "description of class a"
},
{
className: "b",
name: "name of class b",
description: "description of class b"
},
{
className: "a",
name: "name1 of class a",
description: "description1 of class a"
}];
For Eg: If you want to get data of className "a" from the above data, then you can get in the following way:
const dataWithClassA = classData.filter((singleClass) => {return singleClass.className === "a"});
