Set click as default

I´m using Megafolio so now I filter category with clic, but I want to set default category when page loads, how can I do that?
There is my filter function
function completeGalleryContent(data, target, eng) {
var items = data.d.results;
console.log(items);
var menu = "";
var cat = "";
for (var item in items) {
if(items[item].DescriptionEnglish==null)
items[item].DescriptionEnglish="";
if(items[item].Description==null)
items[item].Description="";
if(items[item].Categoria.results!= null && items[item].Categoria.results!= undefined && items[item].Categoria.results.length > 0){
cat =setCategories(eng,items[item].Categoria.results);
}
if (eng){
menu += "<div class='mega-entry " + cat + " cat-all' id='mega-entry-1' data-src='" + items[item].EncodedAbsUrl + "' data-width='' data-height='' data-lowsize=''><div class='mega-covercaption mega-square-bottom mega-landscape-right mega-portrait-bottom mega-red'><div class='mega-title'>" + items[item].TitleEnglish + "</div><p>" + items[item].DescriptionEnglish + "</p></div><div class='mega-coverbuttons'><div class='mega-link mega-red'></div><a class='fancybox' rel='group' href='" + items[item].EncodedAbsUrl + "' title='" + items[item].TitleEnglish + "'><div class='mega-view mega-red'></div></a></div></div>";
}else{
menu += "<div class='mega-entry "+ cat + " cat-all' id='mega-entry-1' data-src='" + items[item].EncodedAbsUrl + "' data-width='' data-height='' data-lowsize=''><div class='mega-covercaption mega-square-bottom mega-landscape-right mega-portrait-bottom mega-red'><div class='mega-title'>" + items[item].Title + "</div><p>" + items[item].Description + "</p></div><div class='mega-coverbuttons'><div class='mega-link mega-red'></div><a class='fancybox' rel='group' href='" + items[item].EncodedAbsUrl + "' title='"+ items[item].Title +"'><div class='mega-view mega-red'></div></a></div></div>";
}
}
$(target).html(menu);
var api = $(target).megafoliopro(
{
filterChangeAnimation: "pagebottom", // fade, rotate, scale, rotatescale, pagetop, pagebottom,pagemiddle
filterChangeSpeed: 400, // Speed of Transition
filterChangeRotate: 99, // If you ue scalerotate or rotate you can set the rotation (99 = random !!)
filterChangeScale: 0.6, // Scale Animation Endparameter
delay: 20,
defaultWidth: 980,
paddingHorizontal: 10,
paddingVertical: 10,
layoutarray: [9, 11, 5, 3, 7, 12, 4, 6, 13] // Defines the Layout Types which can be used in the Gallery. 2-9 or "random". You can define more than one, like {5,2,6,4} where the first items will be orderd in layout 5, the next comming items in layout 2, the next comming items in layout 6 etc... You can use also simple {9} then all item ordered in Layout 9 type.
});
//console.log("entra");
// FANCY BOX ( LIVE BOX) WITH MEDIA SUPPORT
jQuery(".fancybox").fancybox();
//console.log("sale");
// THE FILTER FUNCTION
$('.filter').click(function () {
$('.filter').each(function () { jQuery(this).removeClass("selected") });
api.megafilter(jQuery(this).data('category'));
$(this).addClass("selected");
});
var categorySelected = getParameterByName("Category");
$("div[data-category='"+categorySelected +"']").click();
}
I try change these line like these but did´t works:
var categorySelected = getParameterByName("Office");
Or something like
var categorySelected = getParameterByName().first;
To take first one populated of db

With jQuery, you can use click() function :
$(document).ready(function(){
$('[href="#first_steps"]').click();
});
Just change first_steps by other link if you want.
EDIT
With data-category :
$('[data-category="Office"]').click(); // An html attribute with value

JQuery access some JSON data

I've been working on this for like an hour now, but can't seem to figure it out.
The JSON response:
{"lastDate":"2013-11-22 00:00:35",
"lastId":"42460",
"response":[
{
"class":"rowgreen",
"id":"42460","date":"22 November 2013, 00:00:35\\u0026nbsp;",
"player":"\\u003Ca href=\\u0027logpersonal.php?playerName=skiwi2\\u0027\\u003Eskiwi2\\u003C\/a\\u003E\\u0026nbsp;",
"target":"\\u003Ca href=\\u0027logpersonal.php?playerName=UnholiestElite\\u0027\\u003EUnholiestElite\\u003C\/a\\u003E\\u0026nbsp;",
"weapon":"M1014 (\\u003Cb\\u003EHeadshot\\u003C\/b\\u003E)\\u0026nbsp;",
"server":"Test\\u0026nbsp;"
}
]}
This seems to be correct, now the jquery:
function longPolling() {
if (!longPollingAllowed) {
return;
}
console.log("Long polling started.");
$.ajax({
url: "logpersonal_ajax.php",
data: {
serverId: serverId,
playerName: playerName,
lastDate: lastDate,
lastId: lastId
},
cache: false,
dataType: "json",
beforeSend: function() {
longPollingBusy = true;
},
success: function(json) {
console.log("success");
$(json).each(function() {
console.log("this.lastDate = " + this.lastDate);
console.log("this.lastId = " + this.lastId)
console.log("this.response = " + this.response);
console.log(this.response);
this.lastDate = this.lastDate;
this.lastId = this.lastId;
if (this.response != "") {
this.response.each(new function() {
console.log(this);
var clazz = this.class;
console.log("clazz = " + clazz);
var id = this.id;
var date = this.date;
var player = this.player;
var target = this.target;
var weapon = this.weapon;
var server = this.server;
var string = "\t\t\t<tr class='" + clazz + "' id='" + id + "'><td>" + date + "</td><td>" + player + "</td><td>" + target + "</td><td>" + weapon + "</td><td>" + server + "</td></tr>\n";
console.log("string = " + string);
$(string).insertBefore($("#list tr.header").next());
});
}
});
if (lastDate != "" && lastId != "") {
//longPolling(serverId, playerName, lastDate);
}
longPollingBusy = false;
},
error: function(json, message) {
console.log("fail: " + message);
longPollingBusy = false;
}
});
}
The console.log("this.lastDate = " + this.lastDate); works, so does the one for this.lastId. this.response also works and nicely shows an array starting with index 0 and when expanded it you can see all elements in the developer view.
Now comes the part I cannot seem to understand: At the foreach over this.response it does not print anything useful (except Prototype skeleton) for this.
How can I access the values?

this.response.each(new function() {
This line is wrong. It should be:
this.response.forEach(function() {
P.S. I suggest doing $.each(json, function(){ instead of $(json).each(function() {.

While appending divs, delete older appended divs when there are more than 10

Consider the following JQuery loop. It appends this:
"<div id='1'>" + feedback + "</div>"
1st Question.
I want to increment the id of the appended div after the first one has been appended so that the first appended div's id is 1, the second div's id is 2 and so on.
2nd Question.
When the number of divs reaches 10, I want to delete the first appended div. Which in our case is:
<div id="1">php result</div>
This should keep looping and deleting older divs.
Here's the Jquery ajax loop:
new get_fb();
function get_fb(){
var feedback = $.ajax({
type: "POST",
url: "algorithm.php",
async: false
}).success(function(){
setTimeout(function(){get_fb();}, 8000);
}).responseText;
$('#BuzFeed').append("<div id='1'>" + feedback + "</div>");
}

For counting:
var get_fb = (function() {
var counter = 1;
return function(){
var feedback = $.ajax({
...
}).responseText;
$('#BuzFeed').append("<div id='" + counter + "'>" + feedback + "</div>");
}
})();
get_fb();
and for automatic removal, after
var $buzfeed = $('#BuzFeed').append("<div id='" + counter + "'>" + feedback + "</div>");
add
var $buzfeedDivs = $buzfeed.children('div');
if ($buzfeedDivs.length > 10) { $buzfeedDivs.first().remove(); }
Additionally, your code uses some not-so-good practices. The re-write, including my additions would be:
var get_fb = (function() {
var counter = 0;
var $buzfeed = $('#BuzFeed');
return function(){
$.ajax({
type: "POST",
dataType: "html", // based on chat
url: "algorithm.php"
}).done(function(feedback) {
counter += 1;
var $buzfeedresults = $("<div id='BuzFeedResult" + counter + "'></div>");
$buzfeedresults.text(feedback);
$buzfeed.append($buzfeedresults);
var $buzfeedDivs = $buzfeed.children('div');
if ($buzfeedDivs.length > 10) { $buzfeedDivs.first().remove(); }
setTimeout(get_fb, 8000);
}).fail(function(jqXhr, textStatus, errorThrown) {
var $buzfeedresults = $("<div id='BuzFeedError'></div>");
$buzfeedresults.text('Error: ' + textStatus);
if (typeof console !== 'undefined') {
console.error(jqXhr, textStatus, errorThrown);
}
});
};
})();
get_fb();

How can I compare these strings in jQuery?

This program right now reads in xml code, gets a stock abbreviation, alphabetically sorts them, and then prints them out in an uo list. If you hover over the abbreviations the color will change to red. The goal I'm having is when you hover over an abbreviation, it will show all the data from the xml data just for that company. I tried using the if statement saying if the symbol (abbreviation in xml file) is equivalent to the name (abbreviation in array) then it prints out all the junk for it. The line that prints everything out works correctly in the format I want. I just need to work on the if statement.
What I have figured out is I cannot compare two variables with the ==. Keep in mind symbol is an attribute as well, and name is from an array that stores the symbols. I also tried just saying - if(checkPassword(name, symbol)) - and print it all out as I did in the jQuery code below, but that did not work.
I put a comment next to the if statement I am working on, it's towards the bottom of the jQuery.

Simple weather code using Yahoo API

I want to show the weather on my website. I have some javascript code like
$(function () {
// Specify the ZIP/location code and units (f or c)
//var loc = '10001'; // or e.g. SPXX0050
//var u = 'f';
var loc = 'TUXX0002';
//var loc = 'TUXX0014';
var u = 'c';
//var locA = 'TUXX0002';
//var locI = 'TUXX0015';
var query = "SELECT item.condition FROM weather.forecast WHERE location='" + loc + "' AND u='" + u + "'";
var cacheBuster = Math.floor((new Date().getTime()) / 1200 / 1000);
var url = 'http://query.yahooapis.com/v1/public/yql?q=' + encodeURIComponent(query) + '&format=json&_nocache=' + cacheBuster;
window['wxCallback'] = function (data) {
var info = data.query.results.channel.item.condition;
$('#wxIcon').css({
backgroundPosition: '-' + (61 * info.code) + 'px 0'
}).attr({
title: info.text
});
$('#wxIcon2').append('<img src="http://l.yimg.com/a/i/us/we/52/' + info.code + '.gif" width="34" height="34" title="' + info.text + '" />');
$('#wxTemp').html(info.temp + '°' + (u.toUpperCase()));
};
$.ajax({
url: url,
dataType: 'jsonp',
cache: true,
jsonpCallback: 'wxCallback'
});
});
For now it shows only one location. (with loc variable). I want to add a dropdown or something like a change location link. Than if user selects 'A' location it shows 'A location's weather' etc. I added a dropdown item. Here is the code.
<select id="wxCombo">
<option value="istanbul">istanbul</option>
<option value="ankara">ankara</option>
<option value="izmir">izmir</option>
</select>
Than I add some javascript code for change function, on the same javascript page.
var wxCombo = $("#wxCombo").val();
$("#wxCombo").change(function()
{
if (wxCombo == 'Ankara')
{
loc 'TUXX0002';
}
});
It didn't worked. I need some guide for fixing this issue.

Here's a few things I would change.
First off, declare a function that will update the weather information, based on location:
function updateWeather(loc, u)
{
var query = "SELECT item.condition \
FROM weather.forecast \
WHERE location='" + loc + "' AND u='" + u + "'",
url = 'http://query.yahooapis.com/v1/public/yql?q=' + encodeURIComponent(query) + '&format=json';
$.ajax({
url: url,
dataType: 'jsonp', // this automatically disables cache too
success: function(data) {
var info = data.query.results.channel.item.condition;
$('#wxIcon').css({
backgroundPosition: '-' + (61 * info.code) + 'px 0'
}).attr({
title: info.text
});
$('#wxIcon2').append('<img src="http://l.yimg.com/a/i/us/we/52/' + info.code + '.gif" width="34" height="34" title="' + info.text + '" />');
$('#wxTemp').html(info.temp + '°' + (u.toUpperCase()));
}
});
}
Then, hook this into the .change() handler:
$("#wxCombo").change(function() {
var country = $(this).val();
if (country == 'ankara') {
updateWeather('TUXX0002', 'C');
}
// etc.
});
Demo: http://jsfiddle.net/ZF3aW/

on first glance you are missing an = sign...
var wxCombo = $("#wxCombo").val();
$("#wxCombo").change(function()
{
if (wxCombo == 'Ankara')
{
loc **=** 'TUXX0002';
}
});
