I have a problem with passing a form to an ExtJS6 AJAX request. The docs state:

form : Ext.dom.Element / HTMLElement / String

The form Element or the id of the form to pull parameters from.

Scope is not the problem, this references to Ext.form.Panel

My code is:

I have an EXTJS6.5 application. I want to use variables in my index.html that come from a properties file. However the change of the values of these variables should not require a new build of the application. This means that the variable can be changed if required (Without the need to build the extjs code).

Can someone please help with this?

I have already gone thru other threads where index.html can have placeholders, but do not seem to have a concrete example.

This is my properties file (Runtime.js)

I'm having difficulties retrieving my input values through Extjs6's references. There doesn't seem to be a clear cut answer and google is polluted with answers that seem distinct to many different Extjs versions.

I have a window which contains a textfield and a save button, from the textfield I need to retrieve the user's input and pass it along to my ajax call.

My code:

How do I databind my extjs6 grid to include "commission" using the following format I created from webapi ef?

grid columns should look like this.

In my extjs6 project I have a contextmenu button that I launch a modal popup window with a grid inside. I tried to create it so it only creates the component once, and that window isn't created everytime I click the contextmenu item but I am doing something wrong.

It works the first time, but when I click it the second time I get an error CANNOT READ PROPERTY 'viewModel' of null.

Can someone see what I am doing wrong?

the error appears when I get to this.tempWindow.show()

VIEW, window is popup window, grid is where the itemcontext menu is located

In my extjs6 project I have a grid, I want to add functionality to right click on grid, pick item from menu bar and launch pop up window, but passing row selection through to click method.

So far I have the right click menu bar working, but when clicking on menu item I want to pass through selected row from grid. Can someone help me pass grid row selection to controller method?

my view

In my extjs6 project I have this long running method. Starting with a loaded store, it groups by 'instrument', then creates an array with each item of that 'instrument', then creates a new store with only that data, then creates a series for a extjs chart, and adds the series to the chart.

there is a ton of data with about 100 instruments and a daily number for 2-3 years of data for each instrument. the process takes a long time and I want to update the mask window to say which instrument is being updated so the user can see what is going on.

How can I update the mask message in the middle of this long running method?

In my extjs6 project, in the current page I have a column layout. Inside column 2 I have a chart. How can I make the chart fill that column in height and width? Everything I try is not working.

Below is my view, column 1 has small components so no need to expand contents. I've tried 'fit' height '100%', nothing seems to work properly. also, I am populating the chart AFTER the view is created. not sure if that matters
