Multiple default values in a column of type “Checkboxes”

I got this request from Larry:

choice – Multiple select, check boxes, is there a way to have multiple default values. I may want the same 3 items to always be selected. by default SP only allows one option. This field for 90% may need those 3 requests. Can it be done?

Add this code to a CEWP below the form in NewForm or EditForm: Alter the reference to jQuery as needed.

01	<script type="text/javascript" src="../../Javascript/jquery-1.3.2.min.js"></script>

02	<script type="text/javascript">

03	/* Multiple default values in a column of type "Checkboxes (allow multiple selections)"

13	fields = init_fields();

14	// Define the array if values

15	var myArr = ['Choice 4','Choice 9'];

16	// Call the function with the FieldInternalName of the field and the array.

17	setMultiSelectDefaultValues('MyMultiChoice',myArr);

19	function setMultiSelectDefaultValues(FieldInternalName,arrOfValues){

20	$(fields[FieldInternalName]).find('input:checkbox').each(function(){

21	var thisText = $(this).next().text();

22	if($.inArray(thisText,arrOfValues)>-1){

23	$(this).attr('checked',true);

24

}

25

});

26

}

28	function init_fields(){

29	var res = {};

30	$("td.ms-formbody").each(function(){

31	if($(this).html().indexOf('FieldInternalName="')<0) return;

32	var start = $(this).html().indexOf('FieldInternalName="')+19;

33	var stopp = $(this).html().indexOf('FieldType="')-7;

34	var nm = $(this).html().substring(start,stopp);

35	res[nm] = this.parentNode;

36

});

37	return res;
