concatenate two arrays using javascripts

I have one page on that page pagination are there initially selectable images are coming after selecting 1 or more images user will click on more activities and he want to select more images from that page then he clicks on confirm button all the selected images will go in one array please help me..
check this screen
right now like this coming
localhost/carc_app1/user/modal.php?ids=[{"id":"yoga"},{"id":"aerobics"}][{"id":"net ball"}]
but i want to concatenate both arrays
localhost/carc_app1/user/modal.php?ids=[{"id":"yoga"},{"id":"aerobics"},{"id":"net ball"}]
var item = JSON.parse(localStorage.getItem("test"));
//current page value
var item_json = JSON.stringify(item) ;
var page= <?php echo $json_value; ?>;
var set_image=JSON.stringify(page) ;
var image=set_image.concat(item_json);
alert(image);

// Ok. Let's just parse it once instead of turning it
// into a string and reparsing it 57 times needlessly.
var item = JSON.parse(localStorage.getItem("test"));
// No!!! What is your obsession with stringify???
//current page value
//var item_json = JSON.stringify() ;
var page= <?php echo $json_value; ?>;
// NO. just no.
//var set_image=JSON.stringify(page) ;
var image=page.concat(item);
// You can't alert an array, try console instead
//alert(image);
console.log(image);

How to use explode function to delimit and display different values

I’m making a random sentence generator for my English class. I’m close but because of my limited php and javascript knowledge I need to ask for help. I’m not bad at reading the code, I just get stuck writing it.
I want to use explode to break up a string of comma seperated values. The string is a mix of English and Spanish, on the .txt file they would seperated like:
The book, El libro
The man, El hombre
The woman, La mujer
etc.
I would like to break these two values into an array and display them in separate places on my web page.
I`m going to use a random text generator script that I found, it’s working great with no problems. I just need to modify it using explode to read, separate the values into an array, and be able to display the separate values of the array.
<?php
/* File, where the random text/quotes are stored one per line */
$settings['text_from_file'] = 'quotes.txt';
/*
How to display the text?
0 = raw mode: print the text as it is, when using RanTex as an include
1 = Javascript mode: when using Javascript to display the quote
*/
$settings['display_type'] = 1;
/* Allow on-the-fly settings override? 0 = NO, 1 = YES */
$settings['allow_otf'] = 1;
// Override type?
if ($settings['allow_otf'] && isset($_GET['type']))
{
$type = intval($_GET['type']);
}
else
{
$type = $settings['display_type'];
}
// Get a list of all text options
if ($settings['text_from_file'])
{
$settings['quotes'] = file($settings['text_from_file']);
}
// If we have any text choose a random one, otherwise show 'No text to choose from'
if (count($settings['quotes']))
{
$txt = $settings['quotes'][array_rand($settings['quotes'])];
}
else
{
$txt = 'No text to choose from';
}
// Output the image according to the selected type
if ($type)
{
// New lines will break Javascript, remove any and replace them with <br />
$txt = nl2br(trim($txt));
$txt = str_replace(array("\n","\r"),'',$txt);
// Set the correct MIME type
header("Content-type: text/javascript");
// Print the Javascript code
echo 'document.write(\''.addslashes($txt).'\')';
}
else
{
echo $txt;
}
?>
The script that displays the result:
<script type="text/javascript" src="rantex.php?type=1"></script>
Can someone please help me modify the rantex.php file so that I can use explode to separate the different comma separated values, and use a different script to call them in different places on my web page?
Thank you, and please excuse my noobness.

The following seems unnecessary, since file() will have already removed new line characters:
// New lines will break Javascript, remove any and replace them with <br />
$txt = nl2br(trim($txt));
$txt = str_replace(array("\n","\r"),'',$txt);
To break your line, you may instead use:
list($english, $spanish) = explode(', ', trim($txt));

It seems you are trying to use PHP to serve a static page with some random sentences, right? So why not use PHP to serve valid JSON, and handle to display logic on the client?
Heres a quick implementation.
// Get the data from the text file
$source = file_get_contents('./quotes.txt', true);
// Build an array (break on every line break)
$sentences = explode("\n", $source);
// Filter out empty values (if there is any)
$filtered = array_filter($sentences, function($item) {
return $item !== "";
});
// Build a hashmap of the array
$pairs = array_map(function($item) {
return ['sentence' => $item];
}, $filtered);
// Encode the hashmap to JSON, and return this to the client.
$json = json_encode($pairs);
Now you can let the client handle the rest, with some basic JavaScript.
// Return a random sentence from your list.
var random = sentences[Math.floor(Math.random() * sentences.length)];
// Finally display it
random.sentence
[edit]
You can get the JSON data to client in many ways, but if you don't want to use something like Ajax, you could simply just dump the contents on your webpage, then use JavaScript to update the random sentence, from the global window object.
// Inside your php page
<p>English: <span id="english"></span></p>
<p>Spanish: <span id="spanish"></span></p>
<script>
var sentences = <?= json_encode($pairs); ?>;
var random = sentences[Math.floor(Math.random() * sentences.length)];
var elspa = document.getElementById('spanish');
var eleng = document.getElementById('english');
elspa.innerText = random.sentence.split(',')[1];
eleng.innerText = random.sentence.split(',')[0];
</script>

Ok, so I have this figured out, I take 0 credit because I paid someone to do it. Special thanks to #stormpat for sending me in the right direction, if not for him I wouldn't have looked at this from a JSON point of view.
The .PHP file is like so:
<?php
$f_contents = file('quotes.txt');
$line = trim($f_contents[rand(0, count($f_contents) - 1)]);
$data = explode(',', $line);
$data['eng'] = $data[0];
$data['esp'] = $data[1];
echo json_encode($data);
?>
On the .HTML page in the header:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
(function ($) {
$(function()
{
function load_random_data() {
$.get('random_line.php', function(data) {
var data = $.parseJSON(data);
$('#random_english').text(data.eng);
$('#random_spanish').text(data.esp);
});
}
load_random_data();
$('#get_random').click(function(e){
e.preventDefault();
load_random_data();
});
});
})(jQuery);
</script>
This splits the different variables into classes, so to call them into my html page I call them by their class, for instance I wanted to drop the variable into a table cell so I gave the individual td cell a class:
<td id="random_spanish"></td>
<td id="random_english"></td>
Plus as a bonus the coder threw in a nifty button to refresh the json classes:
<input type="button" value="Get random" id="get_random" />
So now I don`t have to have my students refresh the whole web page, they can just hit the button and refresh the random variables.
Thanks again everyone!

Drupal 6 javascript in module block for front page

I'm trying to create a simple image slider on the front page of my drupal website. I wrote a module with the basic outline as follows
<?php
function slider_init(){
drupal_add_js(drupal_get_path('module', 'slider') .'/slider.js');
}
function slider_block($op = 'list', $delta = 0, $edit = array()) {
$block = array();
switch ($op) {
case "list":
// Generate listing of blocks from this module, for the admin/block page
$block[0]["info"] = t("slider");
break;
case "view":
// Generate content for blocks from this module
$block_content = "";
$block_content .= "hello";
//Query for the projects
$icons = db_query("SELECT * FROM {alumni_frontpage_projects}");
//Initiation arrays from each table column: title, description, url, icon link
$links = array();
$title = array();
$description = array();
$url = array();
//Generate arrays from each table column: title, description, url, icon link
while($icon_data = db_fetch_array($icons)){
$links[] = $icon_data['slider_image_location'];
$title[] = $icon_data['title'];
$description[]= $icon_data['description'];
$url[] = $icon_data['url'];
}
//Count elements in array and randomly choose one
$res = count($links)-1;
$seed = rand(0,$res);
//Generate HTML and Javascript of Slider
//Check that content isn't empty
if ($block_content == "") {
$block_content = t("Sorry No Content");
}
$block["content"] = $block_content;
break;
case "save":
break;
case "configure":
break;
}
return $block;
}
Now, everything is fine. I generate a block and I can place it wherever I want. Great. But I would really like to use javascript in this block so that I can pass the arrays and use onclick events to slide through some images from the arrays i queried. So I found out that I will have to pass the variables into javascript and I'll have to identify the javascript file i want to use in the module.
//add variable to the Javascript
drupal_add_js(array('slider_settings' => array('variable_name' => $variable_name)), 'setting');
//add Javascript file to module
drupal_add_js(drupal_get_path('module', 'slider') .'/slider.js');<br>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I put these in the hook_init BUT NOTHING HAPPENS!!!!! I tested to see basic alerts. If I put hard code into the _block, such as:
$block_content .= '
<script type="text/javascript">
var x
x = 50;
document.write(x); //prints the value of x
</script>';
Then I see '50' prints.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If I try to pass a variable to the hard coded script. That DOES NOT WORK either.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If I try to write 50 through the previous code, but from a separate file called slider.js which is in the same folder using "drupal_add_js(drupal_get_path('module', 'slider') .'/slider.js');", That DOES NOT WORK either (even though I'm not passing a variable)
So what the heck is going on!! Is it possible I'm missing some important core drupal files? Is there a way to trouble shoot this further?
Thanks!

drupal_add_js should work in hook_init().First Check whether your hook function is correctly named as ModuleName_init() or not.

js typing text to screen

hey guys i have a problem with a function which runs just fine on my localhost by when i upload it to the server it doesn't work, could some one please point me to the solution:
var text = "some text";
var textArray = text.split("");
var looptimer;
function letterloop(){
if (textArray.length > 0){
$("#divx").append(textArray.shift());
}
else {
clearTimeout(looptimer);
var div = $("continue").hide().fadeIn(4000);
$("#div").append(div);
return false;
}
looptimer = setTimeout("letterloop()",60);
}
letterloop();

You probably didn't upload the jquery.js file to your server or include it in the HTML <script src="jquery.js"></script>.

You should check whether the js files like jquery you quoted are on the server

Insert javascript from an external script into javascript in the HTML

I have some JS from an external JS file that I want to insert inside of a JS function in the HTML file. I can not touch the JS script in the HTML file, so I am wondering if this method can be done.
Here is the JS I want to insert inside of the JS function in the HTML file.
// FIRST JS TO INSERT
if (OS == "mobile"){
killVideoPlayer();
}
// SECOND JS TO INSERT
if (OS == "mobile"){
loadHtmlFiveVideo();
if (!document.all){
flvPlayerLoaded = false;
}
}else {
loadVideoPlayer();
}
Then I want to insert it into here.
<script>
function mediaTypeCheck() {
if (bsiCompleteArray[arrayIndex].mediaType == "video") {
// INSERT FIRST JS HERE
document.getElementById("bsi-video-wrap").style.display = "block";
document.getElementById('pngBsi').style.display = "block";
document.getElementById("frame_photo").style.display = "none";
document.getElementById("relativeFrame").style.display = "block";
document.getElementById("buy-me-photo-button-bsi").style.display = "none";
// INSTER SECOND JS HERE
loadVideoPlayer();
}
if (bsiCompleteArray[arrayIndex].mediaType == "photo") {
killVideoPlayer();
document.getElementById("bsi-video-wrap").style.display = "none";
document.getElementById('pngBsi').style.display = "block";
document.getElementById("relativeFrame").style.display = "block";
document.getElementById("frame_photo").style.display = "block";
document.getElementById("buy-me-photo-button-bsi").style.display = "block";
if (!document.all){
flvPlayerLoaded = false;
}
}
}
</script>
Thank you!

In JavaScript, you can overwrite variables with new values at any time, including functions.
By the looks of it, you could replace the mediaTypeCheck function with one of your own that does what you need and then calls the original function.
E.g.
(function(){
// keep track of the original mediaTypeCheck
var old_function = mediaTypeCheck;
// overwrite mediaTypeCheck with your wrapper function
mediaTypeCheck = function() {
if ( conditions ) {
// do whatever you need to, then ...
}
return old_function();
};
})();
The above can be loaded from any script, so long as it happens after the mediaTypeCheck function is defined.

The easiest way for me in the past has been using server-side includes. Depending on your back end, you can set up a PHP or ASP page or whatever to respond with a mime type that mimics ".js".
I'm not a PHP guy, but you'd do something like this: (if my syntax is incorrect, please someone else fix it)
<?php
//adding this header will make your browser think that this is a real .js page
header( 'Content-Type: application/javascript' );
?>
//your normal javascript here
<script>
function mediaTypeCheck() {
if (bsiCompleteArray[arrayIndex].mediaType == "video") {
//here is where you would 'include' your first javascript page
<?php
require_once(dirname(__FILE__) . "/file.php");
?>
//now continue on with your normal javascript code
document.getElementById("bsi-video-wrap").style.display = "block";
document.getElementById('pngBsi').style.display = "block";
.......

You cannot insert JS inside JS. What you can do is insert another tag into the DOM and specify the SRC for the external JS file.

You can directly insert js file using $.getScript(url);
if you have script as text then you can create script tag.
var script = docuent.createElement('script');
script.innerText = text;
document.getElementsByTagName('head')[0].appendChild(script);

The issue in your case is that you cannot touch the script in the html, so I'll say that it cannot be done on the client side.
If you could at least touch the script tag (not the script itself), then you could add a custom type to manipulate it before it executes, for example:
<script type="WaitForInsert">

Your question looks some strange, but seems to be possible. Try my quick/dirty working code and implement your own situation:
$(document.body).ready(function loadBody(){
var testStr = test.toString();
var indexAcc = testStr.indexOf("{");
var part1 = testStr.substr(0, indexAcc + 1);
var part2 = testStr.substr(indexAcc + 1, testStr.length - indexAcc - 2);
var split = part2.split(";");
split.pop();
split.splice(0,0, "alert('a')");
split.splice(split.length -1, 0, "alert('d')");
var newStr = part1 + split.join(";") + ";" + "}";
$.globalEval(newStr);
test();
}
function test(){
alert('b');
alert('c');
alert('e');
}
