how to map only parts of images source attribute-CodePudding

$('button').on('click', function(){
var str = $.map($('.bimg'), (e) => $(e).attr('src')).join(',');
console.log(str);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<img class='bimg' src='gall/lorem.jpg' alt='img'>
<img class='bimg' src='gall/ipsum.jpg' alt='img'>
<img class='bimg' src='gall/dolor.jpg' alt='img'>
<button>CLICK</button>

Result:

gall/lorem.jpg,gall/ipsum.jpg,gall/dolor.jpg

What I need:

lorem,ipsum,dolor

You can use regex to get the image name from src.

$('button').on('click', function() {
  var str = $.map($('.bimg'), (e) => $(e).attr('src').match(/\/(.*)\.jpg/)[1]).join(',')
  console.log(str);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<img class='bimg' src='gall/lorem.jpg' alt='img'>
<img class='bimg' src='gall/ipsum.jpg' alt='img'>
<img class='bimg' src='gall/dolor.jpg' alt='img'>
<button>CLICK</button>

Add the following to your map

.split('/').pop().split('.').shift()

So we split on each / and use pop() to get the last one found

Then we'll split on each . and use shift() to get the first part

$('button').on('click', function(){
    var str = $.map($('.bimg'), (e) => $(e).attr('src').split('/').pop().split('.').shift()).join(',');
    console.log(str);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<img class='bimg' src='gall/lorem.jpg' alt='img'>
<img class='bimg' src='gall/ipsum.jpg' alt='img'>
<img class='bimg' src='gall/dolor.jpg' alt='img'>
<button>CLICK</button>

lorem.jpg,ipsum.jpg,dolor.jpg
