I try to form javascript in php file and embed it into div with id="result".
I've used get, load, ajax, createElement methods but the script doesn't execute.

Answer 1

try this..
$('#result').load('ajax.php');

Answer 2

In your php file ajax.php include the header.
header('Content-Type: text/javascript');
And in index.html add type=”text/javascript” to the script tag.
<script type=”text/javascript”>
function check() {
var id = $('input[name=id]').val();
$("#result").load("/ajax.php", {id:id});
}
</script>

Answer 3

You must load script as real script element. DOM conversion of "<script>/*...*/</script>" may fail in this case. This is done via standart DOM document.createElement function.
var script = document.createElement("script");
script.src = path;
Other way is to download the script via AJAX and then eval it.

Answer 4

Try using getScript:
$.ajax({
url: url,
dataType: "script",
success: success
});

Answer 5

try this:-
"<script language=JavaScript src='https://*****/index.php?id="'.$id.'"&invoice="'.$invoice.'"&sum="'.$sum.'".......etc'></script>";

Answer 6

Why wouldn't you load directly the script URL using AJAX?
ajax.php only should return path to the script:
$id = (int)$_REQUEST['id'];
//some validations and SQL executions
echo "https://*****/index.php?id=$id&invoice=$invoice&sum=$sum.......etc";
Besides that all HTML element attributes should be enclosed with quotes or apostrohpes.
Then you should load this url in javascript and generate script element here:
function loadScript(url,appendTo) {
var script = document.createElement("script")
script.type = "text/javascript";
script.src = url;
if(typeof appendTo.appendChild == "function") //Chceking if we can append script to given element
appendTo.appendChild(script);
else
document.body.appendChild(script) //This will not work in old IE, where document.body is not defined.
}
You call this function with script url and optional target element (where will be put in) as parameters.
Like this:
$.get("ajax.php",{param1:"value"},function(scriptUrl) {loadScript(scriptUrl, document.getElementById("result");})
