So here is the thing:
<div id="wrapper" > <div id="x"></div ><div id="x"></div ><div id="x"></div><div id="y"></div>
</div>
So how do i select last div with id=x not y inside of wrapper? Sorry , but i dont know how to pase code to be visible.
An ID is unique so to select it you should just be using
#x {}
I would question why you are using multiple id's though, maybe a class would be better?
Edit
Just noticed you pasted some code.
You really shouldn't be using ID's the way you are, you need to be using classes replace your id's with:
class="x"
If only for modern browsers you can use the last-of-type selector
.x:last-of-type
if going back to IE6 you can always add a class like last and then select it
class="x last"
.x.last {}
Edit For question
To use your wrapper selection you add it to the front of your selector:
#x .x.last {
/** css goodness here **/
}

I want to display some contentlement on every page with fluid templates. My solution was to create a typoscript element like:
lib.my.myelement= CONTENT
lib.my.myelement {
table = tt_content
select {
pidInList = 15
where = uid=99
}
}
and then use it in the fluid template with:
<f:cObject typoscriptObjectPath="lib.my.myelement" />
Another way is to create them directly in fluid with v:content.render or v:content.get. In this example I get all content elements on one page and save them in an array:
<v:variable.set name="contentElements" value="{v:content.get(column:'0', limit:'3', pageUid:'9', render:'FALSE')}" />
I can not use the first solution, cause on this page there will be much different languages ( I could use it, but every time a new language is added I would have work to declare all new uids of the new elements in typoscript).
The second solution would work better, cause when you translate a page the element uids change, but the pageUid does not change. But here I have the problem that I don't just need all elements, I also have to identify each element.
Here is how I use the second solution:
<v:variable.set name="contentElements" value="{v:content.get(column:'0', limit:'3', pageUid:'9', render:'FALSE')}" />
<f:for each="{contentElements}" as="contentElement" iteration="footerIteration">
<div class="column{v:math.sum(a: footerIteration.index, b: 1)}">
<v:content.render contentUids="{0:contentElement.uid}" />
</div>
</f:for>
As you can see, I use every element the same way.
lets create a simple case:
I have a page with the pageUid = 10 (this page will have translations). On every of this translations will be 3 elements. Lets say 1 element got the "id" (with id I mean something how I can identify this element) title1 and the other two elements have the id list1 and list2.
And my question now is How could I access for example list1?
I hope its understandable, if something is not clear please leave a comment.
Edit: I could use the same order on every translation for the elements and then check the iteration in the for-loop (see the second solution) to identify them. But I wonder if there a better, cleaner way.
I'm trying to set a class or id parameter on a <h:inputHidden> in JSF. The code looks like this:
<h:inputHidden value="#{getData.name}" class="targ" />
But in the browser, the class isn't set:
<input type="hidden" name="j_idt6" value="j_idt6">
I need to set a class to this parameter, because I have a JavaScript autocomplete function for a <h:inputText> that sets a value in the hidden input, which needs to be passed in the next page.
Any ideas? Thanks!
I know it's a little bit late, but it can help someone in the future.
As inputHidden shows nothing in the browser there's no sense to allow it to have a class.
You can use the Id but as the Id could change as you change the component parents using it would bring some headache.
I'd suggest as a workaround, you can give it a parent so you can manipulate it by javascript.
Exemple:
JSF
<h:panelGroup styleClass="someCssClass">
<h:inputHidden id="someId" value="someValue" />
</h:panelGroup>
Javascript (using jQuery, you could use pure javascript also)
$('.someCssClass input[type=hidden]').val('yourNewValue');
None of these answers here satisfied my needs (need the PrimeFaces component, need class not ID, wrapping is too much work), so here's what I came up with:
Use pass-through attributes: https://www.primefaces.org/jsf-2-2-pass-through-attributes
Use pass:hidden-class="blah" (in my case, it's xmlns:pass up top)
Use [attribute=value] selector:
https://www.w3schools.com/cssref/sel_attribute_value.asp
document.querySelector multiple data-attributes in one element
That basically boils down to using something like this (because h:inputHidden becomes a regular input): document.querySelector("input[hidden-class=" + blah + "]")
Please, see similar question - How can I know the id of a JSF component so I can use in Javascript
You can sed "id" property, but in final html code it can be not the same, but composite: for example, if your input with id="myhidden" is inside form with id="myform", final input will have id="myform:myhidden".
In the end, I used a standard HTML <input type="hidden"> tag, as I had no advantages for using the JSF one. If you're trying to set a value in a hidden input with JavaScript, I recommend using this workaround.
One part of my meteor application is a semi-collaborative table where users can edit different rows at the same time. When a user is editing a row, the static text values need to switch to input boxes so that the values can be edited and then saved. I would like a template/helper to do this, essentially I want:
<td>
{{#if iAmEditing}}
{{foo}}
{{else}}
<input type="text" name="foo" value="{{foo}}">
</td>
except that there are several columns with different values of "foo" and I don't want to copy and paste this several times. What's the right way to approach this with templates and helpers?
Another approach might be to use the HTML5 contenteditable attribute. Either way, what is the right way to template these values with handlebars?
You should be able to integrate with Bootstrap Editable
For reference, an answer to the original question...
As of today, handlebars partials can't accept anything other than a context argument, but helpers can. Hence. you can define a helper that sets up the context for the template:
Coffeescript:
Handlebars.registerHelper "eventCell", (context, field, editable) ->
return new Handlebars.SafeString(
Template._eventCell
_id: context._id
field: field
value: context[field]
editable: editable
)
Template:
<template name="_eventCell">
<td><div data-ref="{{field}}" class="{{#if editable}}editable{{/if}}">
{{value}}
</div></td>
</template>
Then, I just use the following to render each field:
{{eventCell this "province" iAmEditing}}
I ended up integrating with bootstrap editable, so the template is a little different than my original question. Also, I'm not sure if this is the best way to do it, but it's a lot cleaner than what I had before.
meteor-editable is a new project implementing something like x-editable, but nicely integrated with Meteor reactivity. Unfortunately inline editing is not supported yet (you have to use a popover the way it's set up now).
I am wondering if it is possible to use Knockout.js's ko.applyBindings() multiple times to bind different ViewModels to one part of a page. For example, let's say I had this:
<div id="foo">...</div>
...
ko.applyBindings(new PageViewModel());
ko.applyBindings(new PartialViewModel(), $('#foo')[0]);
I am now applying two ViewModel bindings to <div id="foo>. Is this legal?
You do not want to call ko.applyBindings multiple times on the same elements. Best case, the elements will be doing more work than necessary when updating, worse case you will have multiple event handlers firing for the same element.
There are several options for handling this type of thing that are detailed here: Example of knockoutjs pattern for multi-view applications
If you really need an "island" in the middle of your content that you want to call apply bindings on later, then you can use the technique described here: http://www.knockmeout.net/2012/05/quick-tip-skip-binding.html
This is a common road block that comes when implementing JqueryMobile-SPA.
The method : ko.applyBindings(viewmode,root dom element) accepts two arguments. The second argument comes helpful when you have multiple VM's in your page.
for example :
ko.applyBindings(model1, document.getElementById("view1"));
ko.applyBindings(model2, document.getElementById("view2"));
where view1 and view2 are the root dom element for that model. For a JqueryMobile-SPA this will be the page ids for corresponding model.
The best way to do this would be use the "with" binding construct in the div that you want the partial view model to be bound. You can find it in this fiddle
<div data-bind="with: model">
<p data-bind="text: name"></p>
</div>
<div data-bind="with: anothermodel">
<p data-bind="text: name"></p>
</div>
var model = {
name: ko.observable('somename'),
}
var anothermodel = {
name: ko.observable('someanothername'),
}
ko.applyBindings(model);
Also check out the "with" binding documentation on the Knockout site, to look at an AJAX callback - partial binding scenario.
My english is very bad.... =)
I use Sammy to load partial views, and Knockout to bind the Model, I try use ko.cleanNode but clean all my bindings, all DOM nodes has changed when has a bind, a property __ko__ is aggregated, then i removed that property with this code, and works !!, '#main' is my node.
var dom = dom || $("#main")[0];
for (var i in dom) {
if (i.substr(0, 6) == "__ko__") {
delete (dom[i]);
break;
}
}
after use Ggle translator:

Sorry for the bad wording of the title, but here's my problem. Suppose I have a list where every item has a class:
<ol>
<li class="chapter">Chapter 1</li>
<li class="chapter">Chapter 2</li>
...
I want to select the item which is corresponding to make the user's current chapter, which is known by javascript, in bold. So if the user is on Chapter 2 I would do something like:
$(".chapter:eq(2)").css("font-weight", "bold");
But I can't do
$(".chapter:eq("+currentChapter+")").css("font-weight", "bold");
as it gives me Uncaught SyntaxError: Unexpected identifier
Any help would be appreciated.
Edit: I'm using a template to insert the variables but I have verified that currentChapter is in fact defined and the number I expect it to be.
function fetchContent(startSlide) {ldelim}
var chapterSize = {$chapterSize};
var currentChapter = {$chapter};
var chapterName = "{$chapterName}";
alert(typeof(currentChapter)); // number
alert(currentChapter); //e.g. 3 works
alert(currentChapter + "aaa"); //e.g. 3aaa
$(".chapter:eq("+currentChapter+")").css("font-weight", "bold"); // doesn't work
Try a different approach, fetch all elements and then select only the one you want (I know it's best to select your element right in the selector, but just to try it out).
$(".chapter").eq(currentChapter).css("font-weight", "bold");
Also, looking at your code, it seems like currentChapter is a local variable inside the fetchContent function. Are you sure you can access that variable when you are calling the jQuery function? Try to check the existence and value of the currentChapter variable right before calling the jQuery function which is causing you problems.
EDIT
From the jQuery documentation jQuery :eq() selector
Because :eq() is a jQuery extension and not part of the CSS
specification, queries using :eq() cannot take advantage of the
performance boost provided by the native DOM querySelectorAll()
method. For better performance in modern browsers, use
$("your-pure-css-selector").eq(index) instead.
