How to do equivalent of the following pure JavaScript fragment with MooTools
x = document.createDocumentFragment();
x.[fill with nodes];
document.[somewhere].appendChild(x);
In particular as described in DOM 2 Core after attaching fragment to DOM the original variable x becomes empty DocumentFragment:
If it [the node to add] is a DocumentFragment object, the entire contents of the document fragment are moved into the child list of this node
Edit (2011-04-13 06:30 UTC):
What I'd like to get is something that behaves both as DocumentFragment from DOM 2 Core, but has all nice methods of Elements from MooTools Core.

Is it possible to remove an element (for example ) that exists only after is rendered?
I tried to use query selector inside my .js file:
this.template.querySelector('h3');
But I can't find the target element this way.
I defined component of polymer.js 2.0.
and inside member function of this component, I would like to get current component content as dom object after dom ready. is this possbile?
How can I get dom object of current component after it attached to document?
Since any Custom Element is an HTML element, this is a reference to the DOM object. Custom Elements created with the Polymer library are no different in this regard.
All the methods and properties of the HTMLElement prototype are available inside member functions of a Polymer Element:
_onClick() {
const span = document.createElement('span');
span.innerText = 'hi there!';
this.appendChild(span);
}
Here is a simple JSFiddle for this example: https://jsfiddle.net/vlukashov/oyr5bpyk/

But I have a problem due to that everytime I login SAP CRM generates a new hashed token and will be used in URL like below:

Is there any way to get the value from this DOM Properties using Jmeter?
Usually the choices are in:
CSS/JQuery Extractor
XPath Extractor
Regular Expression Extractor
Choose the one, you're most familiar with. Usually it is Regular Expression Extractor, however parsing HTML with regular expressions is not a good idea, moreover you will be very sensitive to DOM changes (part of the element goes to next line, attributes change positions, etc.).
So I would recommend choosing between CSS and XPath, but choose them wisely. I.e. if the number of styles on the page is not too big - go for CSS, if there are a lot of styles but the DOM itself is not very complicated - choose XPath.
GWT Query selector i.e. $("#id") not working inside callback function. However xyz.find("#id") works, where xyz -> Gquery variable. Is it that callback function doesn't support $ selector or is there some other problem.
Are you sure that the element with id "id" is attached to the dom when the callback function is called ?
When you execute $("#id"), gQuery try to find elements matching the selectors within the set of elements of the DOM tree .
When you execute xyz.find("#id"), gQuery try to find elements matching the selectors inside the array of elements selected by xyz no matter the elements are still or not in the dom tree.
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)
