将json编码的关联数组从php传递给javascript时显示错误

Question

I have an associative array after json_encode like this

{"1":"CourseA", "2":"CourseB"}

and it is stored in a php variable named $jsonObject.Now, I want to send this to a javascript function and use that array inside that function. The function is invoked onclick like this:

 <a href="#" onclick="popup('.$jsonObject.');">link</a>

The problem is: It shows an error:invalid id popup({....

Whats the reason and what should be the solution for that? btw, I am working in moodle and the above link is shown inside a moodle block and declared inside $this->content->text.

Answer 1

Html encode the JSON to escape special characters,

<a href="#" onclick="popup('.htmlspecialchars($jsonObject).');">link</a>
