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:
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 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)

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?

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.
I have been working on this project and I can't get the response that I needed for assertion because the response body in Jmeter only says "Your browser does not support framing. Please update your browser", but Im using the latest version of Firefox (image 2). I also manually execute the request in the real browser, same as what browser Im using in Jmeter, and didn't encounter the said message. Can someone please tell me whats going on? Thank you for your help

Most probably the value you're looking for lives inside an iframe is being loaded using some JavaScript function which is not being kicked off by JMeter as it doesn't evaluate JavaScript.
So you need to invoke the relevant request manually using another HTTP Request sampler which would load the required page. You can figure out the necessary request URL by looking into page source using your favorite browser developer tools or by recording your test scenario using JMeter's HTTP(S) Test Script Recorder.
Also be aware that due to asynchronous nature of JavaScript calls it is better to wrap it (and other JavaScript calls, if any, in Parallel Controller
You can install Parallel Controller and Sampler via JMeter Plugins Manager
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 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.
In my script i have multiple checkboxes,upon selecting which it populate values(like in first group -- Phone,tablets and in other group it --mac,android).I know that jmeter does not support javascript.If i want to automate it in my script that it selects random checkbox during execution.How can i do that?
There are two ways webpages handle dynamic data population.
Pre-caching
All the needed data is fetched from the server during the initial page load, and as the user makes selections, checkboxes or drop-down boxes or tags etc, the data is filtered on the client end and presented to the user. All of this happens through JavaScript execution on the front end and there is no server interaction. If you used JMeter proxy to record the page load, the pre-load should already be included in your test.
In the traditional JMeter testing sense, the subsequent UI interactions cannot be tested with JMeter - as there are no server interactions to simulate. However you can use the web-driver plugin to simulate and measure UI interactions if you so desire, with certain performance caveats as noted on the plugin webpage.
Lazy Loading
Only a minimal amount of data is fetched during page load, and when the user makes a selection a HTTP call (usually a XHR call) is made to fetch additional relevant data from the server. You can use JMeter proxy, fiddler, wireshark or any other HTTP inspection tools to capture the information in this call and convert it to a JMeter HTTP sampler.
The HTTP request url or body should contain parameters indicating what selection the user made in the UI, You need to parametrize/randomize this value to simulate random checkbox selections.
