Hi there I want to ask something very simple , unfortunately I run out of ideas , I want a function when is being $GET to do a JavaScript function straight away, but I just want to make sure that's how you do it...
<script>
function watch()
document.getElementById("home").style.display="none";
document.getElementById("watch").style.display="block";
</script>
<a href="index.php?id=8">8</a>
<?PHP
if(isset($_GET['id'])) {
watch () <<<ISSUE
//run that function if ittselts GET
}
?>Is easy, just do the following:
<a href="index.php?id=8">8</a>
<script>
var myFunction = function() {
...
};
<?php
if(isset($_GET['id'])) {
echo 'myFunction();';
}
?>
</script>
When you receive the id parameter, it will print the code to run the JS function, just put this <script> tags just before </body> so it can be executed after the DOM has been lodaded.
Replace the line with the issue with:
echo "<script>watch() </script>";
Because watch is a Javascript function, and you are calling it like a PHP function.
There are two problems in your code
you cannot name your function "function" since it is a keyword
you'll need to echo the JavaScript function call with php so that it is printed on the document sent to client.
Simply use like below:
<a href="index.php?id=8">8</a>
<?PHP
if(isset($_GET['id'])) {
echo "<script> myFunction () {
...........
}
</script>";
?>
function function- cannot call functions using one of the keywords
