JavaScript/VueJS: Check if an Array contains an object with an element that has specific value

rated 0 times [ 48] [ 7] / answers: 1 / hits: 64188 / 7 Years ago, fri, february 3, 2017, 12:00:00

I would like to solve this problem:

I got an Object that contains a property named specs. This property contains an Array of Objects that all have 2 properties:

name

value

So my object is like this:

Object

-Title

-Date

-Specs [Array]

-- [0] Name: Power

-- [0] Value: 5

-- [1] Name: Weight

-- [1] Value: 100

So - now I would like to check, if my Specs-Array contains an item that has the name Power. If this is the case, I would like to use the value of this element.

How can I solve this?

You can filter the array based on the name attribute and check if the filter returns a result array , if yes then you can use it with index to get the value.

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)
