I have this javascript code which works fine
var QuestionID = panel.siblings('.QuestionIDWrapper').children('input[type=hidden]').val();
but if I convert it to use a multi level jQuery selector like this:
var QuestionID = panel.siblings('.QuestionIDWrapper input[type=hidden]').val();
I don't get any value in QuestionID.
Have a look at the docs: http://api.jquery.com/siblings/
You didn't provide the actual markup, but I assume that while .QuestionIDWrapper is a silbing, input[type=hidden] is not a direct silbing, only a silbings child. (and not matched therefore)
The second one will only select a sibling of panel if it matches the provided selector. Since your input is a child of one of panel's siblings, then it is not at the same level (not a sibling).
.QuestionIDWrapper input[type=hidden] - for this to work input element must be
immidiate child of QuestionIDWrapper class element.
You are using : Descendant Selector (“ancestor descendant”)
Where as in the first one you are seching for the childer elemtn with the specific selector.

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"]')
I have a div-structure like this:
<div id="company1">
<div class="space m-d p-r s-t">
<div class="zzr">
<div class="myTemplate">abc123</div>
</div>
</div>
</div>
I want to get the content form the class "myTemplate" over my "id"-div "company1"
Is it necessary to call all classes in my selector? Would be not good becaus of responsive design, the classes will change. So I woul prefer to call the "#company1" and then directly the "myTemplate". Tried this, but the content is empty and also the selector.
$('#company-'+currentTabIndex).children('.myTemplate').html()
//currentTabIndex has the current Tab-Index, in this case: 1
Firstly, the id property in your HTML has no - in it. Secondly, children looks at direct descendants, whereas you need to use find():
$('#company' + currentTabIndex).find('.myTemplate').html()
That said, you can use a single selector and remove the find() completely:
$('#company' + currentTabIndex + ' .myTemplate').html()
You want .find, not .children:
$('#company-'+currentTabIndex).find('.myTemplate').html()
.find looks for descendant elements. .children just looks for immediate children.
Or a single selector using the descendant combinator (the space before .myTemplate below — gotta love that name):
$('#company-' + currentTabIndex + ' .myTemplate').html()
See also Rory's note about the - in your selector, which isn't in your id. Either remove it from the selector, or add it to the id.
Children searches only for single level child elements, you have to use find().
$('#company-'+currentTabIndex).find('.myTemplate').html()
Given a jQuery object that represents a set of DOM elements, the
.children() method allows us to search through the children of these
elements in the DOM tree and construct a new jQuery object from the
matching elements. The .children() method differs from .find() in that
.children() only travels a single level down the DOM tree while
.find() can traverse down multiple levels to select descendant
elements (grandchildren, etc.) as well.
Reference: .find() - .children().
Instead of
$('#company-'+currentTabIndex).children('.myTemplate').html();
Try
$('#company'+currentTabIndex).find('.myTemplate').html(); //remove '-' from the selector
Use .find() instead of .children() as shown above.
I am trying to get class of fourth cell using eq() selector. Its working without eq selector like this :
alert($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.
$('.wrapper a').find('a'); //return empty object
But i am looking for a way get all anchors by selector. Problem is find method look at only descendants so what is alternative of it ?
Please test it on jsfiddle.net
jQuery find gets the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.
children gets the children of each element in the set of matched elements, optionally filtered by a selector.
I think you are trying to find the elements at the same level then you should use children. Alternatively you can also use filter to filter the matched results based on selector.
filter reduces the set of matched elements to those that match the selector or pass the function's test.
Try this
var div = $('.wrapper div').filter('.parent');
Looking for this?
var div = $('.wrapper div').filter('.parent');
A forked demo of yours
the alternatives of .find() function which are as below:
Child Selector (“parent > child”) it selects only first-level descendants or direct child elements. for example $('#parent_id > #child_id') or $(".parent > .first-level-child")
Descendant Selector (“ancestor descendant”) it selects a child, grandchild, great-grandchild, and so on, of that element. in it you can use $('#parent_id #child_id') or $('#parent_id #grandchild_id') or $(".parent .great-grand-child") or $( "form input" )
.filter() only search in those elements that match the precondition.
.parent() get the parent of each element in the current set of matched elements, optionally filtered by a selector.
.children() it works exactly the same way as find, but it will only find first-level-children, not more distant descendants.
.closest() get the closest (first) element that matches the selector, starting at the current element.
for detailed info about jquery selectors check JQuery Selectors
$('.wrapper a').find('a'); find links inside links that are descendants of .wapprer.
I think you might have meant $('.wrapper').find('a');. In your fiddle that would be
$('.wrapper').find('.parent');`
insetead of:
$('.wrapper div').find('.parent');
<div id="dad">
<img id="mum">
<input>
</div>
With jQuery, how could i get access to the input element, get is value or set it for example? I can't work out how to access something on the same level.. and i dont want to be using ID's, just parent/child nodes so i can use the code for loads of dad div's
Thanks!
an addition to Zed,
$(this).parent().children('input');
if you give a name to your input field then you can easily select throughout the others,
$(this).parent().children('input[name=my_input]');
then you can give any value as:
$(this).parent().children('input[name=my_input]').val('any value');
Sinan.
var myEl = $("#dad").children(":input");
$(this).parent().children() ?
Try this, to find the first child input element:
jQuery("div").find("input:first")
If i understand question, you would like achieve input from mum leve?
So try $("#mum ~ input")...
BTW, great site to search jquery function by category http://visualjquery.com/ +nice example.
I guess you want to find siblings (node with same depth and same parent and in DOM tree)
$(el).next() - next element (sibling) for all elements in the set
$(el).nextAll - all following siblings
$(el).nextUntil - all following siblings, stop on some condition (not including first "bad match").
Besides, you have next adjacent selector (+) and next sibling selector.
The same about prev, prevAll and prevUntil.
And you even have a siblings method.
Check this out.
