To set the value of a Action Form dropdown using JQuery

If you place your code in the On Change/Click section of a form field, the following will work:

form.fields.FieldName.value = "AValue";

*Note the value you are setting must match one of the choices in the dropdown

If you are placing your code in a static text field or the initilization section,

you might need to get in-scope to set it. Try the following example

//gets the scope and uses it to set the value

  angular.element($("#dnn931Size")).scope().form.fields.Size.value = '12px';

//Update the UI with the change
  angular.element($("#dnn931Size")).scope().$apply();

If the Button ID is FillDirectInput,

Use the following syntax to get the ID and insert into a JQuery click command

$('#'+form.fields.FillDirectInput.id).click();

A way to get the form field values from an action form

${{form.fields.BodyType.value}}

form.fields.CarsName.value
form.fields.cbYear.selected.text

Here's a link that shows you how to detect if your page finished loading

jQuery(window).load(function () {
    alert('page is loaded');

    setTimeout(function () {
        alert('page is loaded and 1 minute has passed');   
    }, 60000);

});
