Because you reuse the variable name "content" as the name of your function,
then immediately within the function with this statement:

var content = encodeURI(document.getElementById('content').value);

The function named "content", the variable named "content" within the function and the HTML element with the ID of "content" are separate entities and should *not* be a problem.

It is confusing as all get out, but it remains valid.

you must have noticed that above i have input type=button , therefore the problem is coming, when i take input type=submit then problem does not come.

I don't know that a stdClass is.  That is not a standard JavaScript object.
