How to check if one or more words exist in a url-CodePudding

I'm trying to check if there is one or more words in a url, how could I proceed? I'm trying to check if a url has in it the category that a product has

I tried like this

const url = "http:/localhost/fast-food-ham/hotdog.html";

const words = "Fast Food";
console.log(
  url.toLowerCase().includes(words.toLowerCase())
);

You can use Regular Expressions.

const url = "http:/localhost/fast-food-ham/hotdog.html";

const words = /fast(-|\s)food/i;

if(url.match(words)) {
  console.log(true);
} else {
  console.log(false);
}

The above code prints true if the url contains fast food or fast-food; false otherwise. If you need to print true if is there a character that is not a space between fast and food (eg: fast food, fast_food) you can add \S for the captures in the regular expression:

const words = /fast(-|\s|\S)/i

The last /i means that the case of the text is ignoring. Since that you don't have to url.toLowerCase().

Learn more about regular expressions: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions

Hope this helps.

you can split the string to words:

const url = "http:/localhost/fast-food-ham/hotdog.html";

    const words = "Fast Food";
    words_lst=words.split(" ");
    let isexist=false;
    for (let word of words_lst)
         if(url.toLowerCase().includes(word.toLowerCase())){
            isexist=true;
            break;
        }
    console.log(isexist)

have fun :)

you can try this code

let text = "http:/localhost/fast-food-ham/hotdog.html";

 let words = "Fast Food";
let a = words.replace(/ /g,"-").toLowerCase();
var regex = new RegExp( a, 'i' );
 let result = text.match(regex);
