Retrieve numerical values in inch format from a given string and output the greater value

Question

Retrieve numerical values in inch format from a given string and output the greater value

Trying to extract size information from product names:

Product A 30" Metalic Grey
Product B 31.50" Led 54 watt
Product C 40"-60" Dark Green

The current code for fetching size information is:

var product_name = $(this).text();
product_name.split('"')[0].slice(-2);

Encountering difficulty with sizes containing decimal points like 31.50".

Looking for a better way to extract sizes from the given product names, especially when dealing with size ranges like the third product which should return the larger value of 60.

Answer 1

Answer №1

If you're looking to extract various sizes from a string, one approach is to utilize the power of regular expressions by using the pattern [\d.]+(?="):

var extractedSizes = text.match(/[\d.]+(?=")/g);

This will give you an array containing strings like ["31.50"] or ["40", "60"].

You have the option to perform further operations on this array, such as converting the elements into numbers:

extractedSizes = extractedSizes.map(Number); // ["31.50"] -> [31.50]

Additionally, you could find the maximum value within the array:

var maxFoundSize = Math.max.apply(null, extractedSizes); // ["40", "60"] -> 60

How do you handle this situation?

product_name.replace(/^.*?([\d\.]+)"[^"]*$/, '$1');

Answer №3

To extract the text before the first occurrence of the " symbol, you should locate the last space preceding it:

var product_name = $(this).text();
var size = product_name.split('"')[0];
var space = product_name.lastIndexOf(' ');
size.slice(space, -1);

This process will retrieve everything starting from the " symbol and moving backward to the space just before it.

Below is an illustration showcasing the use of a regular expression (regex) to identify strings and then return the largest one after analyzing each example string:

var examples = [
    'Item X 25" Shiny Red',
    'Item Y 27.75" Glowing Blue 48 watt',
    'Item Z 35"-50" Vibrant Yellow'
]

var findLargestInches = function(str) {
    var inches = str.match(/[0-9]+(\.[0-9]+)?"/g); // Regular expression pattern for inches format

    var largestMeasure = 0;
    for(i in inches){
        var measure = (inches[i]).slice(0,-1); // Remove the trailing "
        largestMeasure = Math.max(Number(measure), largestMeasure);
    }

    return largestMeasure;
}

for(var i in examples) alert(findLargestInches(examples[i]));
