echo '<script type="text/javascript" src="../play.js">player_update(); creature_update();</script>';
I am trying to make these two scripts run when the data from my ajax files echo it to the screen. any help?
Ex: index.php sends data to .js file then js file sends the information to the servers php file which then returns the above script and runs the functions.
A script element with a src will ignore the body of the element completely.
If you want two scripts, then have them in two script elements.
<script src="../play.js"></script>
<script>
player_update();
creature_update();
</script>

I am trying to insert my profile from the external website (url) to my blog.
Cross-domain is prohibited so iframe, AJAX and jquery load don't work. PHP file_get_contents() do but dynamically generated content inside page doesn't load.
Help me to understand why and how can I solve this issue?
I use such code:
<head>
<base href="https://bookmate.com/">
</head>
<?php
$url = 'https://bookmate.com/kirillmazur/finished';
echo file_get_contents($url);
?>
this is due to missing of two javascript file. you can try by adding those two files in to your local directiry
<script src="/javascript/core.js?4417dc0"></script>
<script src="/javascript/modules.js?4417dc0">
check all the missing files in local directory usinging browser console
Hope It will help. I had same problem Here is what I did:
I used iframe and javascript to get page with all the dynamically loaded contents
contents =document.getElementById('load_page1').contentWindow.document.documentElement.outerHTML;
I loaded the page in iframe
<iframe id="load_page1"></iframe>
jQuery(document).ready(function(){
var url="www.google.com"
jQuery('#load_page1').attr('src',url);
});
then from Javascript I get contents of that iframe in a variable on button click event and sent it through ajax by encoding it into base64
<input type="button" id="load_css" />
jQuery(document).on('click',"#load_css",function(){
contents =document.getElementById('load_page1')
.contentWindow.document.documentElement.outerHTML;
contents = btoa(contents);
jQuery.ajax({
url:'process.php',
data:{contents:contents},
method:"post"}).done(function(data){
jQuery('.css_target').html(data);
});
});
and on ajax page I did all the processing thorugh decodeing it back from base64 to string.
so I have this in my HTML file
<script type="text/javascript" src="load.js"> </script>
<script type="text/javascript" src="load2.php"> </script>
Saw somewhere you could call an external php file using the js script tag and whatever js in the php file would be rendered first.
But my problem is, I can't assign no JS variable from load.js to a php variable in load2.php but, however, I could alert using echo "alert(js variable);"; So that tells me it finds the variable and I could use it, but I can't assign it to a php variable :/ any help please?
When working between JavaScript and php you must remember one is client side (JavaScript) and the other server side (php). Therefore php can insert values into javascript before it is sent to the client and then rendered (processed). Although the reverse cannot happen as the "scope" of JavaScript is on the clients computer.
The way around this is to use AJAX requests from the client back to the server sending back the data / variable values you need.
JQuery provides an easy to use library with AJAX functionality.
Please see http://api.jquery.com/jQuery.ajax/
PHP is server-side, JS is client side. This means the PHP will run far before the JS ever gets assigned. The only way a PHP file is going to get a JS variable is if you post it using Ajax
One option would be to dynamically load the PHP-generated script and pass some GET parameters to the PHP. This would still require ajax, but could be done cleanly with jQuery. If you go with jQuery, this is the documentation for getScript.
EDIT
So, your HTML file should look like this:
<!-- your first javascript file -->
<script type="text/javascript" src="load.js"></script>
<!-- load jQuery library -->
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript>
// get the variable from your first javascript file
// via a getter function or global variable
var x = getVarFromFirstFile();
// this will load your second 'javascript' (generated by php) file
// and will pass the variable 'x' as a GET parameter to the php
$.getScript("load2.php?x="+x);
</script>
Then the php in load2.php could access the variable x (originally from load.js) like this:
<?php
$x = $_GET['x'];
...
I have a main html file and I am using ajax to call another php file in same directory.
Inside that php file, I call some external Javascript functions. But my javascripts functions are not working. Is it not possible?
I see generated source in my web browser and it is normal. If i call those functions with using php file (without using ajax), then my functions are working and the generated source same as the previous case. Please help me.
In my html file I am using ajax as follows:
xmlhttp.open("GET","end_location_drop_down.php?q="+str,true);
xmlhttp.send();
in my php file functions as follow,
<?php
echo '<script type="text/javascript" src="../js/pointing.js"></script>'; //external script
$btn8="'btn8'";
$q=$_GET["q"];
echo '<script type="text/javascript">
nextpoint('.$at_id.'); //$at_id mean a variable,nextpoint() is my java script function
</script>';
?>
in my JavaScript function have some image swapping functions.they can call by nextpoint(). But it didn't work.
Javascript functions are executed only when you load the page directly in a browser, as your browser is the one who interprets and executes the javascript code. However when the javascript code is in a different page and that page is being called through AJAX, there is no browser to execute the javascript code before the ajax response is sent back to you. SO it won't work.
Javascript must be executed in browser, so you must insert that script in DOM to current document. Try to insert result of ajax call to DOM.
How do I enter a <? echo "hello"; ?> in a .js file.
This is a jquery app, therefore the js file.
Thanks

You would only be able to do this if the PHP interpreter is configured to run on *.js files, which by default it won't be. Quite honestly, I wouldn't recommend this behavior.
What I'd do instead is something like this (This method can be used for CSS files, too.):
<script type="text/javascript" src="js.php"></script>
js.php
<?php
//GZIP the file and set the JavaScript header
ob_start("ob_gzhandler");
header("Content-type: text/javascript");
//Set a JavaScript variable based on PHP work
echo 'var logged_in_user = "'.$_SESSION['username'].'";';
//Require an external script
require_once($_SERVER['DOCUMENT_ROOT']."/path/to/jquery.js");
?>
//More Javascript functions and code here
$(document).ready(function() {
$('#mydiv').tipsy();
});
<?php
//Flush the output buffer
ob_end_flush();
?>
I personally do this for many reason.
I have many jQuery files I want to include, but I don't want my browser doing 5+ HTTP requests. Including them all in one file means less HTTP requests.
GZIP! I'm significantly reducing the size of the file be transferred and that speeds things up for the visitor.
It's a central location to add, remove, or modify my JavaScript for the whole site. I can even use $_GET checks to make certain scripts conditional based on how I wrote the <script> tag.
For example, <script type="text/javascript" src="js.php?var=1"></script>. I can then check $_GET['var'] within the js.php file.
You regularly don't use PHP within your JavaScript files. Javascript is a client-side language which is interpreterred in your web browser. PHP is run on the web server.
However, if you need to pass data from your PHP-code to your javascript document, you can do something like:
$js = "<script> myObject = " . json_encode($your_data) . " </script>";
print $js;
If you do this in your <head>-part of your HTML-document, you will have access to myObject in other JS files you load after that.
$your_data can be an array or any kind of object, string or integer. Look for PHP JSON around the interwebs.
I think is not possible to enter a php in the js file, but:
try to create an element div for example or an input ...
and then use this functions to get the value of the div tag.
function AddHiddenValue(oForm) {
var strValue = document.getElementById("city").value;
alert("value: " + strValue);
var oHidden = document.createElement("input");
oHidden.name = "printthisinput";
oHidden.value = strValue;
oForm.appendChild(oHidden);
}
It come from another object form (select .. )
document.getElementById("city").value;
Ok guys here is the answer
The Q: I want to input a value for a variable into a .js file, php tags are not permitted and the js would throw an error.
The A: write a
<script> <? var value_pass = echo "hello"; ?> </script> before the said .js file
In the said .js file
var value=value_pass;
So there is no need to have any of the ob_end_flush.
If this is not viable please let me know.
Thanks

i need to have some php code inside javascript
<script ...>
<?php
echo " ... ";
?>
</script>
but this doesnt work. how can u implement php inside javascript that is in a own file javascript.php?
That doesn't do what you probably think it does. It'll work, but the PHP gets run once, when the page is loaded, not every time the JavaScript function is called.
Just for clarification, this is what will happen
index.php
<script type="text/javascript">
<?php echo "alert('hello!');"; ?>
</script>
output html in browser
<script type="text/javascript">
alert('hello!');
</script>
If that is what you want to do, then you can output all the javascript you like. What you cannot do is execute PHP code in the user's browser.
your can use php to dynamically generate javascript code, but you cannot execute php client side. If you need to execute php you will need to postback or use AJAX
There seems to be a good bit of misunderstanding of the question... Here is what you want to do to generate JS from PHP on the server:
file javascript.js.php
<?php
header('Content-Type: text/javascript');
?>
// javascript code here
function PrintTime()
{
alert("The time is " + <?php echo json_encode(time()); ?>);
}
Now, include it on the HTML page using normal script tags:
<script type="text/javascript" src="/url/to/javascript.js.php"></script>
The server will process the PHP file, and return javascript from it.
You can't run PHP inside a javascript file. Primarily because PHP runs server side and is processed before the client is sent any actual http info. JavaScript is processed by the browser on the client side and is sent as text.
It looks like you want to pass some kind of dynamic info to the JavaScript. You can do this by passing a variable like this:
<?php $variable="its me"; ?>
<script>
alert('<?php print($variable)?>')
</script>
The output passed to the client is:
<script>
alert('its me')
</script>
What are you trying to accomplish and maybe we can help you come up with a better solution?
