Code in JavaScript using VueJS to determine if an array includes an object with a certain value in one of its elements

I have a scenario where I need to address the following issue:

I have an Object with a property called specs. This property consists of an Array that contains several other Objects, each having two properties:

  • name
  • value

Here is an example of what my object looks like:

Object
-Title
-Date
-Specs [Array]
-- [0] Name: "Power"
-- [0] Value: 5
-- [1] Name: "Weight"
-- [1] Value: 100

Now, I would like to determine if my Specs Array includes an item with the name "Power". If it does, I want to access the value associated with that element.

Any suggestions on how I can achieve this?

Answer №1

To extract a specific value from an array based on the name attribute, you can apply a filter and then access the desired value using its index.

var data = {specs:[{Name:"Power",Value:"1"},{
    Name:"Weight",Value:"2"},{Name:"Height",Value:"3"}]}
    
var valObj = data.specs.filter(function(elem){
    if(elem.Name == "Power") return elem.Value;
});

if(valObj.length > 0)
    console.log(valObj[0].Value)

Answer №2

Let's assume the main object is named objTemp

You have the option to:

var arrR = objTemp.Specs.filter(function(ele){
   return (ele.Name == "Power")
});

if(arrR.length)
  // property exists
else
  // property does not exist

Answer №3


$.each(object.Specs, function(i, o){
if(o.Name === "Power")
var powerValue = o.Value;
});

Answer №4

To determine if a specific condition exists in an array, you can utilize the some method. This method returns either true or false based on your condition. Here is an example:

var powerIndex
var doesPowerExist = yourObj.specs.some((spec, index) => {
   var powerIndex = index
   return spec.name == "Power"
})

You can then use the variable doesPowerExist to determine whether to proceed with using the value of this element.
