Remove from string using JS

Question

I have a string with a list of filenames such as

var string = '1.jpg,2.jpg,3.png,4.jpg,5.webp'

Is there a way to remove everything that doesn't end in .jpg so the output would look like this:

var newstring = '1.jpg,2.jpg,4.jpg'

Answer 1

You may write something like this

 string
        .split(",")
        .filter(value => value.endsWith(".jpg"))
        .join(",")

Answer 2

Did you experiment with possible regular expressions you could use? You might be able to find the answer yourself thanks to this page from the Mozilla Developer Network: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions

Answer 3

If your string is always a comma separated list, then split the string on commas, which will give you an array of items. Then splice the array and remove items that contain the .jpg pattern.

Answer 4

var string = '1.jpg,2.jpg,3.png,4.jpg,5.webp';
string.split(',').filter((name)=> name.includes('.jpg')).join(',');
//"1.jpg,2.jpg,4.jpg"

Answer 5

var string = '1.jpg,2.jpg,3.png,4.jpg,5.webp';

var stringArray=string.split(',');
newArray=[];

stringArray.forEach(element => {
  if(element.indexOf('.jpg')>-1){ newArray.push(element)}
});

console.log("jpg Array  :"+newArray)// output : jpg Array  :1.jpg,2.jpg,4.jpg
