Prevent line/paragraph breaks in contentEditable

Question

When using contentEditable in Firefox, is there a way to prevent the user from inserting paragraph or line breaks by pressing enter or shift+enter?

Answer 1

$("#idContentEditable").keypress(function(e){ return e.which != 13; });

Solution proposed by Kamens doesn't work in Opera, you should attach event to document instead.

/**
 * Pass false to enable
 */
var disableEnterKey = function(){
    var disabled = false;

    // Keypress event doesn't get fired when assigned to element in Opera
    $(document).keypress(function(e){
        if (disabled) return e.which != 13;
    });                 

    return function(flag){
        disabled = (flag !== undefined) ? flag : true;
    }
}();
