title: How to enter value in text box using Jmeter without post request
body: <p>I am building Jmeter test plan, in website I have one text both and as soon as I enter any value in textbox, it calculates something and populate one value. Here there is no post/get request. So how can I input some value in such case?</p>
  
  <p>I even recorded everything but did not see that value is posting so somehow I will have to enter value into textbox via jmeter without get/post.</p>
  
  <p>In below screenshot 880 is value which I want to insert via Jmeter.</p>
