Javascript money format

Posted on by mario 
Number.prototype.moneyformat = function(decPlaces, thouSeparator, decSeparator) {
	var n = this,
	sign = n < 0 ? "-" : "",
	i = parseInt(n = Math.abs(+n || 0).toFixed(decPlaces),10) + "",
	j = (j = i.length) > 3 ? j % 3 : 0;
	return sign + (j ? i.substr(0, j) + thouSeparator : "") + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + thouSeparator) + (decPlaces ? decSeparator + Math.abs(n - i).toFixed(decPlaces).slice(2) : "");
};

usage:

var myMoney=3543.75873;
var formatedMoney = myMoney.moneyformat(2,'.',',') + ' EUR';

Akismet blows commentmeta wordpress

Posted on by mario

Today I noticed that the commentmeta table in the DB was huge, even the fact that I delete my spam daily. I saw that the commentmeta table had a size of 1,5 MB compared to the other tables with a few kb. I figured out that Akismet plugin caused that. I love that plugin cause it saved me a lot of time filtering the spam comments, but blowing my db is another thing. I have more than this blogs running with much more content. There is might be more trouble with the increase of the table.
However I executed the following query and the size of that table was only 7 kb. Woot!

DELETE FROM `wp_commentmeta` WHERE 
 `meta_key` = 'akismet_as_submitted' 
 OR `meta_key` = 'akismet_history' 
 OR `meta_key` = 'akismet_rechecking'
 OR `meta_key` = 'akismet_result' 
 OR `meta_key` = 'akismet_user' 
 OR `meta_key` = 'akismet_user_result';

Javascript get type

Get the type in javascript

var TYPES = {
    'undefined'        : 'undefined',
    'number'           : 'number',
    'boolean'          : 'boolean',
    'string'           : 'string',
    '[object Function]': 'function',
    '[object RegExp]'  : 'regexp',
    '[object Array]'   : 'array',
    '[object Date]'    : 'date',
    '[object Error]'   : 'error'
},
TOSTRING = Object.prototype.toString;

function type(o) {
    return TYPES[typeof o] || TYPES[TOSTRING.call(o)] || (o ? 'object' : 'null');
};

jQuery UI autocomplete mustMatch Ersatz

Posted on by mario

jQuery UI autocomplete versagt leider, wenn nur Begriffe aus der Liste ausgewählt werden dürfen. Die eingebaute option mustMatch: true funktioniert leider gar nicht. Deshalb eine Funktion, die Abhilfe schafft.

function jQueryUIAutoCompleteMustMatch(input) {
    var found = 0;
    var matcher = new RegExp( "^" + $.ui.autocomplete.escapeRegex( jQuery.trim($(input).val()) ) + "$", "i" );
    jQuery.each($('.ui-autocomplete li'), function(i, val) {
        if(jQuery.trim( $(val).text() ).match( matcher ) ) {
            found = 1;
        }
    });
    if (found) {
        return true;
    }
    else
    {
        $(input).val('');
        return false;
    }
}

Und dann

change: function(event, ui) {
                jQueryUIAutoCompleteMustMatch($(this));
            }

jQuery zoom with all browers

Posted on by mario

Well all browsers can do the same, except for Firefox. Wired, indeed! However this zoom script works in IE, Firefox,Chrome,Safari.

jQuery(document).ready(function() {
    var currFFZoom = 1;
    var currIEZoom = 100;

    jQuery(".make_greater").click(function(){
        var step;
        //only firefox sux in this case
        if (jQuery.browser.mozilla){
            step = 0.05;
            currFFZoom += step;
            jQuery('.maincontent').css('MozTransform','scale(' + currFFZoom + ','+ currFFZoom + ')');
            jQuery('.maincontent').css('transform-origin','0 0');
        }
        else
        {
            step = 5;
            currIEZoom += step;
            jQuery('body').css('zoom', ' ' + currIEZoom + '%');
        }
    });

    jQuery(".make_smaller").click(function(){
        var step;
        //only firefox sux in this case
        if (jQuery.browser.mozilla){
            step = 0.05;
            currFFZoom -= step;
            jQuery('.maincontent').css('MozTransform','scale(' + currFFZoom + ','+ currFFZoom +')');
            jQuery('.maincontent').css('transform-origin','0 0');
        }
        else
        {
            step = 5;
            currIEZoom -= step;
            jQuery('body').css('zoom', ' ' + currIEZoom + '%');
        }
    });
});

        if (jQuery(this).val() == jQuery(this).attr('title')){
            jQuery(this).val('').removeClass('hint');
        }
    }).blur(function() {
