data = JSON.parse(data); syntax error unexpected end of input

I have a problem with my page. It works on localhost (WebServ). On my vps (Debian 8) it not work.
You can look: http://www.csgobeton.pl/withdraw.
When you do recaptcha it says "syntax error unexpected end of input".
In the console I can see there is a problem at line "data = JSON.parse(data);".
Please help me.

Remove frames and loading content into the div

Is there anyway i can unload a page that has been loaded inside an iframe? it likely removing the
windows and loading content from other pages into the div?
I am using iframe on my main screen to call a file left_nav.php
<iframe src='left_nav.php' name='left_nav' class="daemon" scrolling="auto" frameborder='0' height='100%' width="100%"></iframe>
In left_nav functions and methods to load content from other pages like main_title.php
Function created in left_nav.php file below
setEncounter(edate, eid, frname) {
if (eid == active_encounter) return;
if (!eid) edate = '<?php xl('None','e'); ?>';
var str = '<b>' + edate + '</b>';
setDivContent('current_encounter', str);
active_encounter = eid;
encounter_locked=isEncounterLocked(active_encounter);
reloadEncounter(frname);
syncRadios();
var encounter_block = $(parent.Title.document.getElementById('current_encounter_block'));
var encounter = $(parent.Title.document.getElementById('current_encounter'));
var estr = ' <b>' + edate + ' (' + eid + ')</b>';
encounter.html( estr );
encounter_block.show();
}
function loadCurrentEncounterFromTitle() {
top.restoreSession();
top.frames[ parent.left_nav.getEncounterTargetFrame('enc') ].location='../patient_file/encounter/encounter_top.php';
}
function getEncounterTargetFrame( name ) {
var bias = <?php echo $primary_docs[ 'enc' ][ 1 ]?>;
var f = document.forms[0];
var r = 'RTop';
if (f.cb_top.checked) {
if ( bias == 2 ) {
r = 'RTop';
}
}
return r;
}
This is a js script in left_nav to load loadFrame2
function loadFrame2(fname, frame, url) {
var usage = fname.substring(3);
if (active_pid == 0 && usage > '0') {
alert('<?php xl('You must first select or add a visitor.','e') ?>');
return false;
}
if (active_encounter == 0 && usage > '1') {
alert('<?php xl('You must first select or create an encounter.','e') ?>');
return false;
}
if (encounter_locked && usage > '1') {
alert('<?php echo xls('This encounter is locked. No new forms can be added.') ?>');
return false;
}
var f = document.forms[0];
top.restoreSession();
var i = url.indexOf('{PID}');
if (i >= 0) url = url.substring(0,i) + active_pid + url.substring(i+5);
if(f.sel_frame) {
var fi = f.sel_frame.selectedIndex;
if (fi == 1) frame = 'RTop'; else if (fi == 2) frame = 'RBot';
}
if (!f.cb_bot.checked) frame = 'RTop';
top.frames[frame].location = '<?php echo "$web_root/interface/" ?>' + url;
if (frame == 'RTop') topName = fname;
return false;
}
Funtions created in main_title.php file.
function toencounter(rawdata) {
document.getElementById('EncounterHistory').selectedIndex=0;
if(rawdata=='') {
return false;
} else if (rawdata=='New Encounter') {
top.window.parent.left_nav.loadFrame2('nen1','RBot','forms/newpatient/new.php? autoloaded=1&calenc=')
return true;
} else if (rawdata=='Past Encounter List') {
top.window.parent.left_nav.loadFrame2('pel1','RBot','patient_file/history/encounters.php')
return true;
}
var parts = rawdata.split("~");
var enc = parts[0];
var datestr = parts[1];
var f = top.window.parent.left_nav.document.forms[0];
frame = 'RBot';
if (!f.cb_bot.checked) {
frame = 'RTop';
}
parent.left_nav.setEncounter(datestr, enc, frame);
top.frames[frame].location.href = '../patient_file/encounter/encounter_top.php?set_encounter=' + enc;
}

In the last line of code where the new iframe source is set, you're using the href attribute instead of the src. Since iframe does not have an href attribute, that would explain the lack of results.
top.frames[frame].src = '../patient_file/encounter/encounter_top.php?set_encounter=' + enc;
Try changing to that and see if it works.

jquery html(array) doesn't insert all items in array

When I run the javascript code below, it load specified amount of images from Flickr.
By var photos = photoGroup.getPhotos(10) code, I get 10 images from cache.
Then, I can see the object has exactly 10 items by checking console.log(photos);
But actual image appeared on the page is less than 10 items...
I have no idea why this work this way..
Thank you in advance.

I fix your method getRandom() according to this article, and completely re-write method getPhotos():
this.getPhotos = function(numberOfPhotos) {
var available = _cache.length;
if (numberOfPhotos >= available) {
// just clone existing array
return _cache.slice(0);
}
var result = [];
var indices = [];
while (result.length != numberOfPhotos) {
var r = getRandom(available);
if ($.inArray(r, indices) == -1) {
indices.push(r);
result.push(_cache[r]);
}
}
return result;
}
Check full solution here: http://jsfiddle.net/JtDzZ/
But this method still slow, because loop may be quite long to execute due to same random numbers occurred.
If you care about performance, you need to create other stable solution. For ex., randomize only first index of your images sequence.

Codeigniter Auto completion is not working

Hello Auto completion is not working well in my application.When we type a name it displays only a blank list[ Screenshots attached ].
Controller Code
public function list_UserByName($letters)
{
if(strpos($letters, ","))
{
$letters1 = explode(",",$letters);
$lecount = count($letters1);
$letters = $letters1[$lecount-1];
}
$letters = preg_replace("/[^a-z0-9 ]/si","",$letters);
$response=$this->user_model->getAutoUserList($letters);
}
Model Code
public function getAutoUserList($letters)
{
$letters = preg_replace("/[^a-z0-9 ]/si","",$letters);
//AND user_type='C' AND user_status='A'
$query="select * from gm_users where uname Like '%$letters%'";
$result_query =$this->db->query($query);

Am a beginner in php as well as Codeigniter

Just echo your data in your controller
change
$response=$this->user_model->getAutoUserList($letters);
To
echo $this->user_model->getAutoUserList($letters);

change
onkeyup="ajax_showOptions(this,'getCountriesByLetters',event);
to
onkeyup="ajax_showOptions(this,'list_UserByName',event);
there is a question on this topic on stackoverflow, but an entire different process.

How to extract text from a PDF in JavaScript

I wonder if is possible to get the text inside of a PDF file by using only Javascript?
If yes, can anyone show me how?
I know there are some server-side java, c#, etc libraries but I would prefer not using a server.
thanks

Because pdf.js has been developing over the years, I would like to give a new answer. That is, it can be done locally without involving any server or external service. The new pdf.js has a function: page.getTextContent(). You can get the text content from that. I've done it successfully with the following code.
What you get in each step is a promise. You need to code this way: .then( function(){...}) to proceed to the next step.
PDFJS.getDocument( data ).then( function(pdf) {
pdf.getPage(i).then( function(page){
page.getTextContent().then( function(textContent){
What you finally get is an string array textContent.bidiTexts[]. You concatenate them to get the text of 1 page. Text blocks' coordinates are used to judge whether newline or space need to be inserted. (This may not be totally robust, but from my test it seems ok.)
The input parameter data needs to be either a URL or ArrayBuffer type data. I used the ReadAsArrayBuffer(file) function in FileReader API to get the data.
Note: According to some other user, the library has updated and caused the code to break. According to the comment by async5 below, you need to replace textContent.bidiTexts with textContent.items.
function Pdf2TextClass(){
var self = this;
this.complete = 0;
/**
*
* #param data ArrayBuffer of the pdf file content
* #param callbackPageDone To inform the progress each time
* when a page is finished. The callback function's input parameters are:
* 1) number of pages done;
* 2) total number of pages in file.
* #param callbackAllDone The input parameter of callback function is
* the result of extracted text from pdf file.
*
*/
this.pdfToText = function(data, callbackPageDone, callbackAllDone){
console.assert( data instanceof ArrayBuffer || typeof data == 'string' );
PDFJS.getDocument( data ).then( function(pdf) {
var div = document.getElementById('viewer');
var total = pdf.numPages;
callbackPageDone( 0, total );
var layers = {};
for (i = 1; i <= total; i++){
pdf.getPage(i).then( function(page){
var n = page.pageNumber;
page.getTextContent().then( function(textContent){
if( null != textContent.bidiTexts ){
var page_text = "";
var last_block = null;
for( var k = 0; k < textContent.bidiTexts.length; k++ ){
var block = textContent.bidiTexts[k];
if( last_block != null && last_block.str[last_block.str.length-1] != ' '){
if( block.x < last_block.x )
page_text += "\r\n";
else if ( last_block.y != block.y && ( last_block.str.match(/^(\s?[a-zA-Z])$|^(.+\s[a-zA-Z])$/) == null ))
page_text += ' ';
}
page_text += block.str;
last_block = block;
}
textContent != null && console.log("page " + n + " finished."); //" content: \n" + page_text);
layers[n] = page_text + "\n\n";
}
++ self.complete;
callbackPageDone( self.complete, total );
if (self.complete == total){
window.setTimeout(function(){
var full_text = "";
var num_pages = Object.keys(layers).length;
for( var j = 1; j <= num_pages; j++)
full_text += layers[j] ;
callbackAllDone(full_text);
}, 1000);
}
}); // end of page.getTextContent().then
}); // end of page.then
} // of for
});
}; // end of pdfToText()
}; // end of class

I couldn't get gm2008's example to work (the internal data structure on pdf.js has changed apparently), so I wrote my own fully promise-based solution that doesn't use any DOM elements, queryselectors or canvas, using the updated pdf.js from the example at mozilla
It eats a file path for the upload since i'm using it with node-webkit.
You need to make sure you have the cmaps downloaded and pointed somewhere and you nee pdf.js and pdf.worker.js to get this working.
/**
* Extract text from PDFs with PDF.js
* Uses the demo pdf.js from https://mozilla.github.io/pdf.js/getting_started/
*/
this.pdfToText = function(data) {
PDFJS.workerSrc = 'js/vendor/pdf.worker.js';
PDFJS.cMapUrl = 'js/vendor/pdfjs/cmaps/';
PDFJS.cMapPacked = true;
return PDFJS.getDocument(data).then(function(pdf) {
var pages = [];
for (var i = 0; i < pdf.numPages; i++) {
pages.push(i);
}
return Promise.all(pages.map(function(pageNumber) {
return pdf.getPage(pageNumber + 1).then(function(page) {
return page.getTextContent().then(function(textContent) {
return textContent.items.map(function(item) {
return item.str;
}).join(' ');
});
});
})).then(function(pages) {
return pages.join("\r\n");
});
});
}
usage:
self.pdfToText(files[0].path).then(function(result) {
console.log("PDF done!", result);
})

Just leaving here a full working sample.

Here's some JavaScript code that does what you want using Pdf.js from http://hublog.hubmed.org/archives/001948.html:
var input = document.getElementById("input");
var processor = document.getElementById("processor");
var output = document.getElementById("output");
// listen for messages from the processor
window.addEventListener("message", function(event){
if (event.source != processor.contentWindow) return;
switch (event.data){
// "ready" = the processor is ready, so fetch the PDF file
case "ready":
var xhr = new XMLHttpRequest;
xhr.open('GET', input.getAttribute("src"), true);
xhr.responseType = "arraybuffer";
xhr.onload = function(event) {
processor.contentWindow.postMessage(this.response, "*");
};
xhr.send();
break;
// anything else = the processor has returned the text of the PDF
default:
output.textContent = event.data.replace(/\s+/g, " ");
break;
}
}, true);
...and here's an example:
http://git.macropus.org/2011/11/pdftotext/example/

Note: This code assumes you're using nodejs. That means you're parsing a local file instead of one from a web page since the original question doesn't explicitly ask about parsing pdfs on a web page.
#gm2008's answer was a great starting point (please read it and its comments for more info), but needed some updates (08/19) and had some unused code. I also like examples that are more full. There's more refactoring and tweaking that could be done (e.g. with await), but for now it's as close to that original answer as it could be.
As before, this uses Mozilla's PDFjs library. The npmjs package is at https://www.npmjs.com/package/pdfjs-dist.
In my experience, this doesn't do well in finding where to put spaces, but that's a problem for another time.
[Edit: I believe the update to the use of .transform has restored the whitespace as it originally behaved.]

For all the people who actually want to use it on a node server:
/**

*/
"use strict";
let pdfUrl = "http://example.com/example.pdf";
let request = require('request');
var pdfParser = require('pdf2json');
let pdfPipe = request({url: pdfUrl, encoding:null}).pipe(pdfParser);
pdfPipe.on("pdfParser_dataError", err => console.error(err) );
pdfPipe.on("pdfParser_dataReady", pdf => {
//optionally:
//let pdf = pdfParser.getMergedTextBlocksIfNeeded();
let count1 = 0;
//get text on a particular page
for (let page of pdf.formImage.Pages) {
count1 += page.Texts.length;
}
console.log(count1);
pdfParser.destroy();
});

It is possible but:
you would have to use the server anyway, there's no way you can get content of a file on user computer without transferring it to server and back
I don't thing anyone has written such library yet
So if you have some free time you can learn pdf format and write such a library yourself, or you can just use server side library of course.
