What is the best way to cut the file name from 'href' attribute of an 'a' element using jQuery?

Question

For example I\'ve got the simple code:

  
Download file 01

        

Answer 1

var fileNames = new Array();

$('.list a').each(function(i, item){
    fileNames.push(this.href.substring(this.href.lastIndexOf('/') + 1))
});

This will give you an array of all the filenames, then:

for(var x=0; x<fileNames.length; x++)
{
    // Do something with fileNames[x]
}

Answer 2

use

lastIndexof and substring

Give anchor tag an id

var elem = document.getElementById ( "anch1" );

elem.href.substring (elem.href.lastIndexOf ( '/' ) + 1 );

Using jQuery

$(function() {
    $("ul.list li a").each ( function() {
        alert ( $(this).attr ( "href" ).substring ($(this).attr ( "href" ).lastIndexOf ( '/' ) + 1 ) )
    });
});

Answer 3

Here another way:

var arr = [];
$("ul.list li a").each (function(){
    arr.push( (this.href.match(/\/[^\/]+$/)[0] || '').substr(1) );
});

Answer 4

Though you don't have them in this case, in general you would want to strip off the ?search and #hash parts before looking for the last slash to get the file's leafname.

This is very easy using the built-in properties of the link object like pathname instead of processing the complete href:

var a= document.getElementById('link1');    // or however you decide to reference it
var filename= a.pathname.split('/').pop();  // get last segment of path

Answer 5

var files = $('a[href]').map(function() {
    return this.pathname.match(/[^\/]*$/)[0];
});

a[href] will exclude anchors without hrefs (such as named anchors), and pathname will remove query strings and fragments (?query=string and #fragment).

After this, files will contain an array of filenames: ['file01.pdf', 'file02.pdf'].

Answer 6

var myFilename = [];
$("ul.list li a").each(function() {
      var href = $(this).attr('href'); 
      var idx = $(this).attr('href').lastIndexOf('/');
      myFilename.push((idx >= 0) ? href.substring(idx+1) : href);
});
