How to display images in a table dynamically?

I am making a table whose data is dynamically changed with the following script. I also want to display the respective images of the groups beside the group names. When the group names will change, the image will also change.
The table works absolutely fine.
The image files are there in my ide, so the path mentioned is correct. However the images are not displayed.
<script>
//$, jQuery
var lookupTable = {
Palm: "PM",
Cedar: "CED",
Oak: "OA",
Chinar: "CHI"
};
var setGroup = function(groupName) {
var t = jQuery('<div></div>').addClass('group');
var tn = jQuery('<div></div>').addClass('group-name').appendTo(t);
jQuery('<img>').attr('src','/examples/media/images/'+ groupName.toLowerCase() + '.png').appendTo(tn);
jQuery('<span></span>').text(groupName).appendTo(tn);
return t;
};
$.getJSON('https://service_program', function(data){
var taf = $('#item1').empty();
var tar = $('#item2').empty();
var tat = $('#item3').empty();
var tao = $('#item4').empty();
jQuery.each(data, function(idx, game){
if (game['Category'] === 1){
var tr = $('<tr></tr>').appendTo(taf);
} else if (game['Category'] === 2) {
var tr = $('<tr></tr>').appendTo(tar);
} else if (game['Category'] === 3){
var tr = $('<tr></tr>').appendTo(tat);
} else if (game['Category'] === 4){
var tr = $('<tr></tr>').appendTo(tao);
}
$('<td></td>').text(game['group 1']).appendTo(tr);
$('<td></td>').text(game['group 2']).appendTo(tr);
$('<td></td>').text(game['itemName 1']).appendTo(tr);
$('<td></td>').text(game['itemName2']).appendTo(tr);
});
});
</script>
Where am I going wrong?

use this:
$('<td></td>').$('<img>').attr('src','/examples/media/image/'+ groupName.toLowerCase() + '.png').appendTo(tr);

isotope items disappearing when resize browser

I hacked an isotope combofilter with checkboxes, but here is the problem with the isotope items; They are disappearing when resizing browser window.
I dont why they are not displaying when I change the size of the browser!
Please so help!!
Normaly I use isotope V2. Here in JSFiddle, there is np with the window resizing however I used isotope v1..
I am driving crazy, when items disappeared I need to trigger by clicking a select button, then its going fine.
var $containerii;
var filters = {};
jQuery(document).ready(function () {
var $containerii = $('.isotope').isotope({
itemSelector: '.isotope-item'
});
getContent: '.isotope-item li'
var $filterDisplay = $('#filter-display');
$containerii.isotope();
// do stuff when checkbox change
$('#options').on('change', function (jQEvent) {
var $checkbox = $(jQEvent.target);
manageCheckbox($checkbox);
var comboFilter = getComboFilter(filters);
$containerii.isotope({ filter: comboFilter });
$filterDisplay.text(comboFilter);
});
});
function getContent() {
var items = document.getElementById("containerii")
}
function getComboFilter(filters) {
var i = 0;
var comboFilters = [];
var message = [];
for (var prop in filters) {
message.push(filters[prop].join(' '));
var filterGroup = filters[prop];
// skip to next filter group if it doesn't have any values
if (!filterGroup.length) {
continue;
}
if (i === 0) {
// copy to new array
comboFilters = filterGroup.slice(0);
} else {
var filterSelectors = [];
// copy to fresh array
var groupCombo = comboFilters.slice(0); // [ A, B ]
// merge filter Groups
for (var k = 0, len3 = filterGroup.length; k < len3; k++) {
for (var j = 0, len2 = groupCombo.length; j < len2; j++) {
filterSelectors.push(groupCombo[j] + filterGroup[k]); // [ 1, 2 ]
}
}
// apply filter selectors to combo filters for next group
comboFilters = filterSelectors;
}
i++;
}
var comboFilter = comboFilters.join(', ');
return comboFilter;
}
function manageCheckbox($checkbox) {
var checkbox = $checkbox[0];
var group = $checkbox.parents('.option-set').attr('data-group');
// create array for filter group, if not there yet
var filterGroup = filters[group];
if (!filterGroup) {
filterGroup = filters[group] = [];
}
var isAll = $checkbox.hasClass('all');
// reset filter group if the all box was checked
if (isAll) {
delete filters[group];
if (!checkbox.checked) {
checkbox.checked = 'checked';
}
}
// index of
var index = $.inArray(checkbox.value, filterGroup);
if (checkbox.checked) {
var selector = isAll ? 'input' : 'input.all';
$checkbox.siblings(selector).removeAttr('checked');
if (!isAll && index === -1) {
// add filter to group
filters[group].push(checkbox.value);
}
} else if (!isAll) {
// remove filter from group
filters[group].splice(index, 1);
// if unchecked the last box, check the all
if (!$checkbox.siblings('[checked]').length) {
$checkbox.siblings('input.all').attr('checked', 'checked');
}
}
}

If your using isotope v2, try this:
var $containerii = $('.isotope').isotope({
itemSelector: '.isotope-item',
isResizeBound: true
});
v1.5, this:
ADDENDUM
I don't see anything disappearing, just the col-md-10 shifting down when you resize your window. I changed the layout to avoid the shift and it seems to resize as it should.
jsfiddle

Thank you so much for helps and valuable responses. Finally I solved my problem by using trigger isotope on window resize at the end of the code.
$(window).on('resize', function () {
$containerii = $('.isotope');
triggerIsotope();
});

Cannot search multiselect after modification

I have 2 multi selects in a page, and I need to transfer some of the option in first into second, while mantaining the search capabilities.
The problem is, that when I use the search input, it restores the selects to their original options...
Here is the jquery search function:
jQuery.fn.filterByText = function(textbox) {
return this.each(function() {
var select = this;
var options = [];
$(select).find('option').each(function() {
options.push({value: $(this).val(), text: $(this).text()});
});
$(select).data('options', options);
$(textbox).bind('change keyup', function() {
var options = $(select).empty().data('options');
var search = $.trim($(this).val());
var regex = new RegExp(search,"gi");
$.each(options, function(i) {
var option = options[i];
if(option.text.match(regex) !== null) {
$(select).append(
$('<option>').text(option.text).val(option.value)
);
}
});
});
});
};
Here is the js fiddle : http://jsfiddle.net/C2XXR/ !
*I believe the problem lies in the options variable, but have no idea on how to solve it *
Thanks!

I have updated the fiddle. http://jsfiddle.net/C2XXR/2/
I have updated the code for right and left transfer. You have to change the option array itself got the filter, adding them in the dom will not work. In the changed code one issue is once we add from right to left or left to right it is getting added in the last position of the target select.
Please check and let me know if this is what you want.
Below is the main changed function. Later you can create a common function i suppose. Code can be optimized more.
$('[id^=\"btnRight\"]').click(function (e) {
var selected = $(this).parent().prev('select');
var target = $(this).parent().next('select');
target.find('option[value="999"]').remove()
var options = selected.data('options');
var selectedVal = selected.find('option:selected').val()
var tempOption = [];
$.each(options, function(i) {
var option = options[i];
if(option.value != selectedVal) {
tempOption.push(option);
}
});
var targetOptions = target.data('options');
targetOptions.push({value: selected.find('option:selected').val(), text: selected.find('option:selected').text()});
target.data('options', targetOptions);
selected.find('option:selected').remove().appendTo('#isselect_code');
selected.data('options', tempOption);
});
$('[id^=\"btnLeft\"]').click(function (e) {
var selected = $(this).parent().next('select');
var target = $(this).parent().prev('select');
var options = selected.data('options');
var selectedVal = selected.find('option:selected').val()
var tempOption = [];
$.each(options, function(i) {
var option = options[i];
if(option.value != selectedVal) {
tempOption.push(option);
}
});
if( tempOption.length == 0 )
{
// add 999 here
}
var targetOptions = target.data('options');
targetOptions.push({value: selected.find('option:selected').val(), text: selected.find('option:selected').text()});
target.data('options', targetOptions);
selected.find('option:selected').remove().appendTo('#canselect_code');;
selected.data('options', tempOption);
});

the problem with your code is that after you click btnRight or btnLeft your collection of options for each select is not updated, so try after click on each button to call your filterByText as the following :
$('[id^=\"btnRight\"]').click(function (e) {
$(this).parent().next('select').find('option[value="999"]').remove()
$(this).parent().prev('select').find('option:selected').remove().appendTo('#isselect_code');
$('#canselect_code').filterByText($('#textbox'), true);
$('#isselect_code').filterByText($('#textbox1'), true)
});
$('[id^=\"btnLeft\"]').click(function (e) {
$(this).parent().next('select').find('option:selected').remove().appendTo('#canselect_code');
$('#canselect_code').filterByText($('#textbox'), true);
$('#isselect_code').filterByText($('#textbox1'), true)
});

hr tag in javascript

I am working on phonegap and I am new to it. I want to draw a line using hr under the menu items which are displayed. but unfortunately I am unable to do so.
if somebody can help in this regard. Thanks in advance.
here is the code snippet
{
success:function(res,code) {
entries = [];
var xml = $(res);
var items = xml.find("item");
$.each(items, function(i, v) {
category1.push($(v).find("category").text());
/* $("#status").append("menu_type <b>"+menu_type+"</b><br/>"); */
console.log( "PRICE" + ": " + $(v).find("menu_type").text() );
});
var category = category1.unique();
var select = document.getElementById("selectNumber");
for(var i = 0; i < category.length; i++) {
var el1 = document.createElement("li");
var opt = category[i];
var el = document.createElement("a");
el.textContent = opt;
el.value = opt;
el1.appendChild(el);
select.appendChild(el1);
}
}

Try adding something like this
document.getElementById("ElementBelowWhichHRShouldCome").appendChild(document.createElement('hr'));

Try innerHTML. Here is an example:
http://jsfiddle.net/Wxv6n/
var doc = document;
var get = function(id){return doc.getElementById(id);};
get("foo").innerHTML = '<hr/>';
..and don't forget to cache your references to document

After Every Menu Item,you can use this.Its pretty simple.
$("#menu_item").after('<hr/>');

How to assign values to a combobox

Ill post an image to explain it better.
So, imagine that I make a 1st search, then I make a 2nd, or 3rd, 4th..search and I want to back to my old searches.
I already have some code that saves old searches (working fine). My only problem is how to assign the values to a combobox in order to comboboxes return to an old state.
How could I start doing this?
edit:
$('#combos').on('change', '.combo', function() {
var selectedValue = $(this).val();
if (selectedValue !== '' && $(this).find('option').size() > 2) {
var newComboBox = $(this).clone();
var thisComboBoxIndex = parseInt($(this).attr('data-index'), 10);
var newComboBoxIndex = thisComboBoxIndex + 1;
$('.parentCombo' + thisComboBoxIndex).remove();
newComboBox.attr('data-index', newComboBoxIndex);
newComboBox.attr('id', 'combo' + newComboBoxIndex);
newComboBox.addClass('parentCombo' + thisComboBoxIndex);
newComboBox.find('option[value="' + selectedValue + '"]').remove();
$('#combos').append(newComboBox);
}
});
var check_combo_box_values = $('#combos .combo').map(function ()
{
return $('option:selected', this).map(function() {
return parseInt(this.value);
}).get();
}).get();

I made a fiddle how to add options to a combobox
http://jsfiddle.net/hRQqp/2/
Since you stated you had no troubles with saving the old searches, you should be able to put the pieces together
var dropdown = document.getElementById('dropdown');
var list = [
"first",
"second",
"third"
];
// remove old options
while (dropdown.length> 0) {
dropdown.remove(0);
}
// add new ones
for (var i=0;i<list.length; i++) {
var option = document.createElement("option");
option.textContent = list[i];
option.value = i;
dropdown.appendChild(option);
}​
