convert HTML file contents into a string in Javascript -


i'm asking users upload , html file, convert contents of html file string.

html file:

<form action="">   <input type="file" name="pic" accept="html" id = "htmlfile"> </form>

javascript

function readtextfile(file) //this wrong think {     var rawfile = new xmlhttprequest();     rawfile.open("get", file, false);     rawfile.onreadystatechange = function ()     {         if(rawfile.readystate === 4)         {             if(rawfile.status === 200 || rawfile.status == 0)             {                 var alltext = rawfile.responsetext;                 alert(alltext);             }         }     }     rawfile.send(null); }

if understand correctly, can read file after input change filereader this:

function readsinglefile(evt) {    //retrieve first (and only!) file filelist object    var f = evt.target.files[0];       if (f) {      var r = new filereader();      r.onload = function(e) {         var contents = e.target.result;        alert( "got file.n"               +"name: " + f.name + "n"              +"type: " + f.type + "n"              +"size: " + f.size + " bytesn"              + "contents:" + contents             );        }      r.readastext(f);    } else {       alert("failed load file");    }  }    document.getelementbyid('htmlfile').addeventlistener('change', readsinglefile, false);
<form action="">    <input type="file" name="pic" accept="html" id="htmlfile">  </form>

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
