parsing - How can I parse a text file using javascript -

the code below read text file using javascript. works. however, want read part of content. example, content of file :"hello world!" want display "hello". tried function split(), works on strings. don't know how insert here.

 var urls = ["data.txt"];  function loadurl() {     var urltoload = urls[0];     alert("load url ... " + urltoload);     browser.setattributens(xlinkns, "href", urltoload); } 

thank you!!!

i used

jquery.get('http://localhost/foo.txt', function(data) { var myvar = data; }); 

, , got data text file.

or try this

jquery provides method $.get can capture data url. "read" html/text document, needs accessible through url. once fetch html contents should able wrap markup jquery wrapped set , search normal.

untested, general gist of it...

var html_file_url = '/whatever/html/file.html';  $(document).ready(function() {     $.get(html_file_url, function(data) {         var filedom = $(data);         filedom.find('h2').each(function() {             alert($(this).text());         });     }); });
