Hi,

In the user form there are text input objects like "Team" and "Organisation" which allow any arbitrary input strings.
Now I'd like to replace the text objects with a select objects so that only predefined values can be chosen. As I understand it, changes to the core forms are overwritten with an update.

Is there nevertheless a possibility? Because I would like to prevent invalid entries from being made in some fields.

Hi Timo,

You are right. Changes to nuBuilder's core forms are overwritten whenever you run an update.
To prevent this from happening, you can execute JavaScript code in the (Setup->) header.

This example shows how to turn the Team and Department Text objects into Select object.

Code: Select all

function nuOnLoad() {

 if(nuFormType() == 'edit'){
 
     // Edit Form loaded
     if (nuGetProperty('form_id') == 'nuuser') {
        nuReplaceWithSelectObject('sus_team', ["","Team 1", "Team 2", "Team 3"]);
        nuReplaceWithSelectObject('sus_department', ["","Department 1", "Department 2"]);
     }

 } else
 if(nuFormType() == 'browse'){
     // Browse Form loaded
 }
 
}

function nuReplaceWithSelectObject(i, options) {

	let obj = $('#' + i);

	let p = obj.position();
	let h = obj.height();
	let w = obj.width()+2;
	let id = obj.data('nu-object-id');
	let field = obj.data('nu-field');
	let tab = obj.data('nu-tab');
	let placeholder = obj.attr('placeholder');
	let title = obj.attr('title');
	let value = obj.val();
	
	obj.replaceWith('<select id="' + i + '" onchange="nuChange(event)"></select>');  

    let optionList = document.getElementById(i).options;

    options.forEach(option =>
      optionList.add(
        new Option(option, option, false, option == value)
      )
    );

    let objNew = $('#' + i); 

	objNew.css({top: p.top, left: p.left, height: h, width: w, position: 'absolute'});
	objNew.attr('data-nu-object-id', id)
		  .attr('data-nu-field', field)
		  .attr('data-nu-form', '')
		  .attr('data-nu-tab', tab)
		  .attr('data-nu-format', '')
		  .attr('data-nu-prefix', '')
		  .attr('data-nu-type', 'input')
		  .attr('data-nu-data', '')
		  .attr('data-nu-access', '0')
		  .attr('placeholder', placeholder)
		  .attr('title', title)
}
