I'm trying to count the text inside my title tag. But it doesn't seem to work. I've tried count(), strlen() etc. For example:
<title>Count me!</title>
When i use strlen() i get this error:
strlen() expects parameter 1 to be string, object given
When i use count u just get 2. I think it counts the title tags inside my file.
Controller:
$title = $dom->getElementsByTagName('title');
$count = strlen($title);
Index:
{{$count}}
$title_tag = $dom->getElementsByTagName('title');
foreach($tital_tag as $title){
$title_length = strlen($title->nodeValue);
}
You need to loop through title tags ... It doesn't mean you have multiple tags . Dom simply return object which need to be accessed and then you get length of title
According to the documentation, DOMDocument::getElementsByTagName returns a DOMNodeList object, not a string.
You need to iterate over the elements in the list with a foreach loop and retrieve the length of each node's value.
Just an alternative using jquery you can count the character as follows :
<script type="text/javascript">
$(document).ready(function(){
var title = $(document).prop('title').length;
console.log(title);
});
</script>
You can't achieve the result doing just that because what the getElementsByTagName() function does is return "A NodeList object, representing a collection of elements with the specified tag name.".
ie. if you called it on a ul tag it would give you a collection of li tags within that ul.
You could try this though;
<html>
<head>
<title>Heello</title>
</head>
<body>
<script type="text/javascript">
var text = document.getElementsByTagName("title")[0].innerHTML.length;//get the length of the first title tag
alert(text);//text no contains the length of characters within the title tag
</script>
</body>
</html>Note: The elements in the returned collection are sorted as they appear in the source code.
