I need to make script what can get load time of page (img, css, etc)
example: enter image description here
There is "Retrieve All Embedded Resources" box which instructs JMeter to parse response DOM and fetch all images, scripts, styles, fonts, sounds, etc. like real browser does:
I would also suggest adding HTTP Cache Manager as real browsers download these "resources" only once and on subsequent iterations they are being returned from the browser cache.

When I launch my application through JMeter in a browser - contents of the Login page are not displayed.
So I recorded a very basic scenario - just launching the Login page of my application through fiddler and imported it as a jmx file to JMeter. When I run the script, I see that the script fails.
If JMeter is not able to launch the page while recording, will JMeter to able to run a script that is recorded from Blazemeter/Fiddler for the same page?
As per JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
So JMeter will download the DOM and the scripts (as well as images, fonts, styles, sounds, etc.) given you "tell" JMeter to do this via HTTP Request Defaults
however it won't execute the JavaScript.
If your scripts don't generate any network requests - you can just skip it as scripts are executed in browser context so you should not be too interested in the timings. If the scripts are triggering network requests - you should be able to record them using JMeter's HTTP(S) Test Script Recorder and add them after the "main" request which gets the content of your login page.
You can put the "main" and the "scripts" request(s) under the Transaction Controller - this way you will also get "cumulative" time of their execution.
jmeter http request results in a page that has div's, but the div's do not contain the rest of the http page.
If I use a browser's developer's view, I can expand the div's to see the rest of the http page results.
How do I get jmeter to show everything that is below the div's? The problem with getting all of the embedded resources is that the embedded resource shows ALL of the possible resulting page code for many different pages. I simply need the RESULT of ONE page to do testing that is specific to THAT page result.
You need to tick Retrieve All Embedded Resources on "Advanced" tab of the HTTP Request sampler (or even better HTTP Request Defaults). If you're receiving resources you're not interested in you have URLs must match input which acts in 2 modes:
You can put specify URL pattern which will match your ONLY ONE PAGE
You can specify URL pattern which will not match specified pages, i.e. something like ^((?!google|facebook|cdn|yahoo|microsoft).)*$ will exclude requests originating from google, facebook, cdn, yahoo and microsoft domains.
Patterns should be in form of Perl-5 style regular expressions. See Excluding Domains from the Load Test for more details.

So if you "divs" are populated by AJAX calls - JMeter will not execute them automatically, you will need to add the relevant HTTP Request samplers to mimic each AJAX call separately. As real browsers execute JavaScript asynchronously (in parallel) you should put these requests under Parallel Controller
And finally to put everything together it makes sense to place all the requests under Transaction Controller so you could measure how much time does whole sequence take.
I have a form, which is inside a div on page. When page is loaded, form start to load with a loading screen. JMeter capture it, when page is loaded, it doesn't wait for the form, so page loader is on 0 % when I view results. I tried to use Constant Timer to delay processing. JMeter says too early in this case, that request is successful, because a failure can happen during loading of input fields.
JMeter waits for the whole response with one little exception, as per JMeter project main page:

So if your form is being loaded via AJAX request JMeter won't automatically execute it, you will have to add a separate HTTP Request sampler to invoke the relevant AJAX request(s) which will load your form.
In order to mimic real browser's behavior you can put the main and the "AJAX" requests under Parallel Controller (you can install it using JMeter Plugins Manager)
I recorded application. It record login get method page as the only html page. login post method pages not recorded instead it record as one authorization manager and some APIs. How can I load testing using only html pages. Now my record script seems full of APIs instead of .html pages. I asked to my developers. They told "In submit buttons they call APIs related to those pages". Help me to get out of this problem.
You must not record these requests to .js and woff2 as this is not how real browsers behave.
Real browsers execute main request to what you call "html page" followed by concurrent download of "embedded resources", in your case JavaScript and Font files. To make your JMeter test to behave more like a real browser you need to:
Exclude these requests from recording. Click "Add suggested excludes" button in the HTTP(S) Test Script Recorder
When you finish recording and will be preparing your script for execution add HTTP Request Defaults to your Test Plan, switch to the "Advanced" tab and tick Retrieve All Embedded Resources and Parallel Downloads boxes
This way you will be properly handing JavaScripts, Fonts, images, styles, whatever in your load test.
Just to be sure, if you load a page and let's say this page has 3 images. First refere to "/images/1.jpgn", the second to "/images/2.jpg" and the third to "/images/1.jpg" again. When the page sent to the browser, will the browser make a new request to the server and ask for the image? And if the image has already been request (like my "lets say", it has two time the same image) will it request it again or it will know that this image/url has already been loaded and will just retrieve it from the temp?
Which lead to my second question, is there a way to save with javascript/jquery this image on the computer (with the download box opening like if you were downloading a file) from the temp without having to request it again from the server?
I don't know if I am really clear but in short, I want to save an image of the page from the cache and not request a download to the server.
Browsers generally cache what they can, according to what the HTTP response headers say. That is, servers ultimately control what browsers can (or should) cache, so it's server configuration that usually controls such things.
This applies not only to images but all content: HTML pages, CSS, JavaScript, etc.
It is all on how the server sends the image the 1st time (with or without caching).
If you have caching enabled on your browser, the browser will usually check your cache before requesting the file from the server.
The browser should take care of. It won't continually re-request the same file.
Typically, the browser will see that two images have the same source and therefore only download it once.
However if the same image is requested again later, the browser will send an If-Not-Modified-Since header to the server. The server can then respond with 304 Not Modified, at which point the browser uses the local copy to "download instantly".
