Javascript & JQuery

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();

Say you have a checkbox field, and you want to know if a particular option has been checked. Here is the JS to do it.

Example:

Fieldname: ManagerList

Manager to test for: 33

Items currently checked: 33, 34

Syntax:   '[ManagerList]'.indexOf("33") != -1

This means, starting at position 0 in the string of chosen options, the position of the first occurance of "33" is not -1

Otherwise you could easily get

- [ManagerList] returns 33,34
- [ManagerList:JsonArray] returns ["33","34"]

------------

Also

I think you can use the syntax

[CheckboxList].includes('Other')

in the Bind Expressions / Show of the optional field.

See my repro - here

Setting fields to Display:none hides them but the row that they are in still takes up vertical space. When you want to collapse that space, add the following

Add this class to the hidden field: HideFormGroup

Add this bit of JS somewhere in the form:  $('.form-group-HideFormGroup').parent().css("display","none");

dnnsf.api.actionForm.initForm(843, {});

843 is the ModuleID

Use this function to set the value of a dropdown with auto complete

function setAutocompletCurrentValue(id, value) {
   $(id).val(value);
   var textToShow = $(id).find(":selected").text();
   $(id).parent().find("span").find("input").val(textToShow);
}

Called like this:

setAutocompletCurrentValue(dnn843GCSFieldName, 'test');

Notes:

The value you set it to must be a correct choice for the control from its dataset,

Not sure if the single quotes are needed or not.
