I want to trigger a JavaScript function after the page loads all the elements and I have to echo some HTTP request data into the page somewhere and use JavaScript to get the information from the DOM.
Therefore, I create the function and fire it on page load using jQuery but it didn't call the javascript (I think the DOM hasn't loaded) so how can I fix this?
<script>
$( document ).ready(function(){
myFunction(); // firing the function
});
</script>
<script>
function myFunction(){
var target = document.getElementById("target");
var formscount = target.textContent(); // the number of items from [#target]
alert(target);
if (formscount > 0) {
active="";
for (i=0; i < formscount; i++) {
var str='active'
if (i > 0){
str = ''
}
$('#DOM').append($('SOME HTML ELEMENTS');
event.preventDefault()
}
}
}
</script>
DOM Called (target) for passing the data ($_POST['itemscount']):
<?
$count = $_POST['itemscount'];
?>
<div id="target" style="display:none;">
<? $output = $_POST['productscount']; // or $Count //
echo htmlspecialchars($output);
?>
</div>
First, textContent is not a function. So it should be written like this:
var formscount = target.textContent;
Second thing, you are missing the closing bracket ) in line $('#DOM').append($('SOME HTML ELEMENTS');
$('#DOM').append($('SOME HTML ELEMENTS'));
Third thing, event.preventDefault() will not work, as event is undefined. You may remove it.
and lastly, php tags begins with <?php and not with only <?.
<?php
$count = $_POST['itemscount'];
?>
<div id="target" style="display:none;">
<?php
$output = $_POST['productscount']; // or $Count //
echo htmlspecialchars($output);
?>
</div>
