Question

function get() {

    $.post(
        'postchatfame.php', 
        {
            comment: postchatfamemsg.comment.value,
            userid: postchatfamemsg.userid.value
        },
        function(output) {
            $('#walls').html(output).show();
        }
    );

    document.forms["postchatfamemsg"].reset();

}

This is my code I used as Ajax, to store information into DATABASE. and returned some information in tabular form to the same page without refreshing page.
I called this function onclick of button by writing this code.

<input name="a" type="button" value="Share" onClick="get();"/>

Answer 1

I suggest a different name for the function – some names already have a meaning in HTML and the DOM, so using such a name may conflict with them (calling a function submit has similar problems).

Why not give it a more descriptive name – getChatFame, for example?
