Getting Elements of a Div from Another Page (Php)

Getting elements of a div from another page (PHP)

You can use DOMDocument in PHP:

<?php

$doc = new DomDocument;

// We need to validate our document before refering to the id
$doc->validateOnParse = true;
$doc->loadHtml(file_get_contents('http://google.com/bla.php'));

var_dump($doc->getElementById('div1'));

?>

how to pass the id of a div to another php page when it is clicked

Not sure if this will suffice, but you could try this:

<a href="<?php echo 'video_tut.php?vid_id='.$video_id; ?>" title="View post details">
    <img width="370" height="193" src="http://img.youtube.com/vi/<?php echo  $video_id?>/hqdefault.jpg" class="img-responsive wp-post-image" alt="Teen girl sitting with a laptop" />
</a>

Instead of getting the id from the div, I added the id as a GET query in the href of the a element. Then in the video_tut.php, you can use this to get the id value:

if(isset($_GET['vid_id'])){
    $vidID = $_GET['vid_id'];
}

Here I'm assuming that exposing the $video_id in the URL does not pose some sort of security risks.

How to pass a div created with javascript to another page with php

You shouldn't have to send the entire div just the amount of data that's required for the next page to recreate it.
i.e. you could use a cookie and have the user remember:

document.cookie = "divinfo=The text field of the div's;\
                   path=/";

have a hidden input field that contained the relevant information.

<input name="divinfo" hidden value="The info required for the creation of the div"/>

If you use the cookie the javascript could recreate the data on the other side if you use the hidden input you should have the php recreate it.

Change loaded div from another page with another one on the same page

When the ("#innercont1").click event listener is created, there is no element in the DOM with the id innercont1, since that element is dynamically loaded from elsewhere. What you need for this instance is an event listener that will catch any element with that id at any time. You can bind the listener to the body element instead, like so:

$(document.body).on('click', '#innercont1', function(){
    //code
});

how to get all elements of div from another page in web service aspx

Pass it like this

JSON.stringify({'num':HTML});

You have to stringify the content to JSON properly. HTML may contain synataxes that would make
the JSON notation invalid.

  var dataToSend = JSON.stringify({'num':HTML});
         $.ajax({ url: "EditingTextarea.aspx/GetValue",
                type: "POST",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                data: dataToSend , // pass that text to the server as a correct JSON String
                success: function (msg) { alert(msg.d); },
                error: function (type) { alert("ERROR!!" + type.responseText); }

            });

Hyperlink to a div on another page in PHP

You are dealing with named anchors.

In this, you can give link to a particular section in the page.

E.g.

Say, I have following divs.

<div id="first">Bla Bla</div>

And this div is far below header, you can give a link to it using hash.

<a href="#first">Go to First</a>

By clicking on the link, your respective div will get focused.
