Select all the elements within an element having an attribute set to a specific value

I have the followings defined :
var excludedFiltersPanel = $("#excludedFiltersPanel");
var includedfiltersPanel = $("#includedfiltersPanel");
where *Panel is just a div.
in excludedFiltersPanel there are some div's with attribute data-iscorefilter="true" e.g. :
<div id="filterPanel-LastName" class="filterPanel" data-iscorefilter="true">
<Some Stuff here!>
</div>
I am trying to get them and move them to includedfiltersPanel:
It seems neither of these is a correct syntax:
excludedFiltersPanel.('[data-iscorefilter="true"]')
excludedFiltersPanel.$('[data-iscorefilter="true"]')
1.What is the correct syntax?
2.How do I append them to includedfiltersPanel? (I know how to append a single item, but not sure what is the common good practice here, e.g. using for loop or some JQuery magic)

Since excludedFiltersPanel there are some div's with attribute data-iscorefilter="true"
Use .find()
Description: Get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.
It would look like :
excludedFiltersPanel.find('[data-iscorefilter="true"]')

id to fields in jquery

I have a table and I have multiple text boxes in a column.I am add rows to the table using jquery clone method
var row = $('#nameTable tbody>tr:last').clone(true);
Now I want to add ids to the text fields of the new row.
Any help?

Just add attribute id to that new row object.
$(row).find('input').attr("id","newId");
Docs of attr()
note: Considering only one input element is there in your new object. If multiple input elements are there, you have to loop on them and have assign individual id's to them, Since Id must be unique.

Try with this
var row = $('#nameTable tbody>tr:last').clone(true);
row.find("#someInput").attr("id","someInput_2");

Since you referring to text fields you can make use of this selector
$(row).find('input[type=text]').each(function(element) {
element.attr("id","newId");
})

For set multiple IDs use (be careful, because ID must be unique):
var row = $('#nameTable tbody>tr:last').clone(true);
row.find(':text').each(function () {
this.id = 'new_id' + Math.random();
});
I prefer access to ID via pure javascript instead of jquery http://jsperf.com/browser-diet-this-attr-id-vs-this-id/12

Get class of forth cell adjacent to current cell

I am trying to get class of fourth cell using eq() selector. Its working without eq selector like this :
alert($cell.closest( "td" ).next().next().next().attr("class"));
I tried using multiple variation of eq() but it's not working please help.
None of the below are working.
$cell = $(this);
alert($cell.find( "td" ).eq(3).attr("class"));
alert($cell.closest( "td" ).eq(3).attr("class"));
alert($cell.( "td:eq(3)" ).attr("class"));

That's not how the eq method work.
Given a jQuery object that represents a set of DOM elements, the .eq() method constructs a new jQuery object from one element within that set. The supplied index identifies the position of this element in the set.
As the closest method returns one element, eq(3) returns an empty set in here. You can use the nextAll method for creating a set of next siblings. Then eq(3) will return the fourth element in that set:
$cell.closest("td").nextAll().eq(3).attr("class");
Please note that if this here refers to a td element then closest('td') does nothing.

How to select cell using jQuery id selector

I am getting ID of table cell using the following Javascript
var tempCell = e.target.parentNode.id;
Now I have to append a table in tempCell using jQuery like that
var htmlToAppend = '<table id="tbleSelectApproovers"></table>';
$(???).append(htmlToAppend);
I am not sure how to write the syntax to use id for the purpose to add table in td. What to write in place of question mark to add table in tempCell

You have to give id to td in id selector. Before id you need to give #
$('#idoftd').append(htmlToAppend);
If you can get the element by e.target.parentNode then you can pass it to jQuery method to make jQuery object out of it.
$(e.target.parentNode).append(htmlToAppend);

use escaping rule from selector http://api.jquery.com/category/selectors/
$('#e\\.target\\.parentNode\\.id').append(htmlToAppend);
or
$('[id="e.target.parentNode.id"]').append(htmlToAppend);
update:
$('#'+e.target.parentNode.id).append(htmlToAppend);
or
$('#'+tempCell ).append(htmlToAppend)

From the looks of it you are trying to append the element to the current elements parent so
var htmlToAppend = '<table id="tbleSelectApproovers"></table>';
$(e.target.parentNode).append(htmlToAppend);

easy way : keep an id or class attribute to the table cell like for example say
<td id="tablecellid">
now if you want to append anything keep it in a variable for readability
var data = ''
and do the following
$("#tablecellid").append(data);

Assuming your cell looks like this:
<td id='myfavcell'></td>
you would call
$('#myfavcell').append(htmlToAppend);
as jquery uses the css selector type (#) for locating element IDs.

How to get attributes of container in jquery?

How can I get attributes values from an container using jquery ?
For example:
I have container div as:
<div id = "zone-2fPromotion-2f" class = "promotion">
here how can I get attribute id value using jquery and than how can I trim the value to get component information ?
update : how can i get attribute values ?
UPDATE: If I have multiple components on page with same div information than how would I know what attribute value is for which component ?
Thanks.

First, that seems to be a ridiculously long ID -- I'm sure it could be made much shorter while still retaining its uniqueness.
Anyway, on to the answer: First you need a way of accessing your "container" div. Typically, one might use a class or ID to get an element. For example, you could "select" this div with the following call to jQuery:
var container = jQuery('#zone-3a...'); // Fill in ... with really long ID
But, since you're asking how to retrieve the ID, I'm presuming that selecting it via the ID is not an option. You could also select it using the class, although it's not guarenteed to be the only element on the page with that class:
var container = jQuery('.promotion');
There are other ways to narrow down the search, such as:
jQuery('div.promotion');
jQuery('div.promotion:first');
Once you have a reference to your "container", you can retrieve the ID like so:
container.attr('id'); // => zone-3a...
// or:
container[0].id; // => zone-3a...

So assuming your div looks like this.
<div id="foo"/>
You could get the ID attribute by using the attr method.
$("div").attr("id);
That assumes that you only have one div on the page. Not really sure what component information you are looking to get?

You read node attributes with the attr() method.
var id = $( '.promotion' ).attr( 'id' );
In terms of parsing that ID for any other arbitrary information, I can't say since it looks like you're using some sort of proprietary format of which I have no knowledge.

loop thru and get all divs with the class promotion and get the id of each...
$('div.promotion').each(function(){
var attr = $(this).attr('id'); // or whatever attribute
});
or single
var myDivClass = $('zone-3a-2f-2f-2fPortal-2fPages-2fHome-2fZones-2fLeft-2f-7ccomponent-3a-2f-2f-2fSpm-2fComponents-2fPromotion-2f').attr('class');
or another single
var myDivID = $('.promotion').attr('id');
