As a beginner in programming, I am looking to create a filtering feature that allows users to filter results by a specific price range. Users should be able to input a minimum and maximum price to receive a list of items within that range. I am currently utilizing JavaScript and Angular 4 for the front end development.
To easily extract items with prices within a specified range, you can utilize the filter method in JavaScript. Here's a simple function that achieves this:
function filterItemsByPrice(items, minPrice, maxPrice){
return items.filter(item => item.price >= minPrice && item.price <= maxPrice);
}
One possible solution is to utilize the Array.filter() method, which filters out values in an array based on a specified condition.
For instance, if you have an array of price values stored in a variable named values:
var values = [10, 20, 30, 40, 50],
min = 15, max = 45;
var filteredValues = values.filter(function(value) {
// Filter out values that are greater than min and less than max
return value > min && value < max;
}
// The resulting filteredValues will be [20, 30, 40]
While there are more elaborate ways to write this function, the basic syntax above aims to provide clarity on its functionality :)
Alternatively, you can refer to this example for further insight.
