Custom JavaScript form gets resetted in SimpleXML

Hello, everyone!

I'm trying to create a Splunk 6 SimpleXML dashboard with an <html> within a row. This html snippet contains a pretty simple form with a set of checkboxes and a submit button. The form should validate and process checkbox states and send it to an external web service.

I tried to do the following:

Insert a script="myscript.js" parameter into a toplevel <dashboard> tag
In myscript.js, I write:

require(['jquery'], function($) {

... functions ...

$(document).ready(function() {
$('#myform').submit(submit_func)
load_checkbox_states_from_external_source();
});

});

The problem is that checkboxes' states are not always loaded, and submit button is not always able to submit information (clicking on it just doesn't call any function at all). I checked everything - all functions are getting called and working good, but then some mysterious force resets all checkboxes' states and button's handler back to default. Calling these two functions with a 1 second timeout seems to help, but it isn't a nice and reliable solution.

What do you think, splunkers, what should I do here?

P.S. it seems that Advanced XML does not have this issue, but I do want to use Simple XML, because every other dashboard is written in Simple XML and I want to keep look&feel consistent throughout the app.

Try adding "simplexml/ready!".

require([
    'jquery',
    'splunkjs/mvc/simplexml/ready!'
], function($) {
...
}

Your tip seems to be a solution, thank you! I tried to reload my page about 10-15 times, and I didn't see a single checkbox getting resetted.

Could you point me to an explanation of "simplexml/ready!" thing, please?
