I have an unordered list with several divs contained inside. Each list item is created with jquery and put into a variable.
I need a way to select the :nth-child(even) of each div within the jquery object.
ele = myList.append("<li> \
<div class='name'>"+this.name+"</div> \
<div class='test'>test</div> \
</li>");
How would I use the variable "ele" within a jquery object to get the nth-child contained within?
What I had imagined, which doesn't work:
$(ele+" div:nth-child(even)").addClass("my-class");
Another thing I imagined
ele.children("div:nth-child(even)").addClass('my-class'));
Also doesn't seem to work.
use .find()
ele.find("div:nth-child(even)").addClass('my-class');

I need to create the element and then delete it. Is there a way to find the element by it's text after it was created?
The xpath of the element is //div[#id='mif-tree-6']/span/span[3].
You can use xpath for it for example. Like:
//div[#id='mif-tree-6']//span[contains(text(),'your_text_here')]
UPDATE
Please provide an example of your html. It is possible to find a parent of your element with xpath and after that to find all the childs. For example your html =
<div id='lol'>
<div>first_item</div>
<div>second_item</div>
<div>third_element</div>
</div>
You get an array of elements with xpath =
//div[contains(text(),'first_')]/../div
So you can do something like:
click | //div[contains(text(),'first_')]/../div[2]
BUT if there are a lot of brothers-elements to find by text of one sibling it will be necessary to use loop to get every of them.
Once again. If you will provide full information about what are you doing and an example of your html it will be much easier to suggest.
I am trying to implement something which I hope is relatively straight forward... I have one component (lets call it the wrapper component) which contains another component (lets call it the inner component) inside it via the data-sly-resource tag:
<div data-sly-resource="${ 'inner' # resourceType='/projectname/components/inner' }"></div>
I would like to pass in some additional parameters with this tag, specifically a parameter that can be picked up by sightly in the inner component template? I am trying to specify whether the inner templates outer html tag is unwrapped based on a parameter being passed in when the component is called via data-sly-resource.
After experimenting and perusing the sightly documentation, I can't find a way of achieving this.
Does anyone know if this is possible?
Many thanks,
Dave
You can use the Use-API to write and read request attributes if the alternatives proposed here don't work for you.
A quick example of two components where the outer component sets attributes that are then displayed by the inner component:
/apps/siteName/components/
outer/ [cq:Component]
outer.html
inner/ [cq:Component]
inner.html
utils/ [nt:folder]
setAttributes.js
getAttributes.js
/content/outer/ [sling:resourceType=siteName/components/outer]
inner [sling:resourceType=siteName/components/inner]
/apps/siteName/components/outer/outer.html:
<h1>Outer</h1>
<div data-sly-use="${'../utils/setAttributes.js' # foo = 1, bar = 2}"
data-sly-resource="inner"></div>
/apps/siteName/components/inner/inner.html:
<h1>Inner</h1>
<dl data-sly-use.attrs="${'../utils/getAttributes.js' # names = ['foo', 'bar']}"
data-sly-list="${attrs}">
<dt>${item}</dt> <dd>${attrs[item]}</dd>
</dl>
/apps/siteName/components/utils/setAttributes.js:
use(function () {
var i;
for (i in this) {
request.setAttribute(i, this[i]);
}
});
/apps/siteName/components/utils/getAttributes.js:
use(function () {
var o = {}, i, l, name;
for (i = 0, l = this.names.length; i < l; i += 1) {
name = this.names[i];
o[name] = request.getAttribute(name);
}
return o;
});
Resulting output when accessing /content/outer.html:
<h1>Outer</h1>
<div>
<h1>Inner</h1>
<dl>
<dt>bar</dt> <dd>2</dd>
<dt>foo</dt> <dd>1</dd>
</dl>
</div>
As commented by #AlasdairMcLeay, this proposed solution has an issue in case the inner component is included multiple times on the request: the subsequent instances of the component would still see the attributes set initially.
This could be solved by removing the attributes at the moment when they are accessed (in getAttributes.js). But this would then again be a problem in case the inner component is split into multiple Sightly (or JSP) files that all need access to these attributes, because the first file that accesses the request attributes would also remove them.
This could be further worked-around with a flag telling wether the attributes should be removed or not when accessing them... But it also shows why using request attributes is not a good pattern, as it basically consists in using global variables as a way to communicate among components. So consider this as a work-around if the other two solutions proposed here are not an option.
There is a newer feature that request-attributes can be set on data-sly-include and data-sly-resource :
<sly data-sly-include="${ 'something.html' # requestAttributes=amapofattributes}" />
Unfortunately it doesn't seem to be possible to construct a Map with HTL (=Sightly) expressions, and I don't see a way to read a request attribute from HTL, so you still need some Java/Js code for that.
unfortunately, no. there is no way to extend sightly functionality. you cannot add new data-sly attributes or modify existing ones. The best you can do is write your own helper using the USE API
If you just need to wrap or unwrap the html from your inner component in different situations, then you can just keep the html in the component unwrapped, and wrap it only when needed by using the syntax:
<div data-sly-resource="${ 'inner' # resourceType='/projectname/components/inner', decorationTagName='div', cssClassName='someClassName'}"></div>
If you need more complex logic, and you need to pass a value to your inner component template, you can use the selectors. The syntax for including the resource with selectors is:
<div data-sly-resource="${ 'inner' # resourceType='/projectname/components/inner', selectors='mySelectorName'}"></div>
The syntax to check the selectors in the inner component is:
${'mySelectorName' in request.requestPathInfo.selectorString}"
or
${'mySelectorName' == request.requestPathInfo.selectorString}"
I use SHtml.jsonForm in myjsonclass.show to wrap a jsonform to the HTML page with the following command:
<div id="form" class="lift:myjsonclass.show">
It works fine.
The SHtml.jsonForm method defines a random id for the form tag, I wonder if there is a solution to get that id and use it in the HTML. It will make easier for example to apply form validators in Javascript.
I have solved that by accessing a known element of the form and asking for its parent in javascript: element.parent(); So I am able to get id of the form with: element.attr('id').
I'm using an API that returns a JQuery Object which is a reference to a DIV container. I know my structure inside of the DIV container. I basically need to read some attributes from the first .
I've tried chaining the standard selectors off of my object but I get an error.
XML filter is applied to non-XML value ({selector:"div.panes > div.slice(0,1)", context:({}), 0:({}), length:1})
[Break on this error] var svideo = $(api.getCurrentPane()).('a').get(0);
Change your code to use .find() when you're going for descendant elements, like this for the DOM element reference directly:
$(api.getCurrentPane()).find('a').get(0)
//or..
$(api.getCurrentPane()).find('a')[0]
or if you want a jQuery object...
$(api.getCurrentPane()).find('a:first')
//or..
$(api.getCurrentPane()).find('a:eq(0)')
//or..
$(api.getCurrentPane()).find('a').eq(0)
typically when you refer to an object you would use a selector like this :
$(this).jqueryfunction()
if u would need an element within this object you would use :
$('typicalselector',this).jqueryfunction()
My question is how would I use jquery selector to select various objects something along the lines of :
($(this.fistobject) and $(this.secondObject)).jqueryfunction()
thanks for your help
When you wrap an object or run a selector, you get a set or collection. So this would return a collection and then add another collection to it, and then perform jqueryfunction() to the combined set:
$('someSelector').add('anotherSelector').jqueryfunction()
This works with contexts, too.
You can use a comma, just like in CSS. I.e.
$('div, a', this)
would select all div and a elements in 'this'.
I dont think you can work jQuery on Javascript objects, they should be jQuery-wrapped HTML Elements.
You can use multiple selectors like this:
$(selector1, selector2, ..., selectorn).jqueryfunction();
