Hi,
I previously posted this question as jquery/javascript: arrays - http://stackoverflow.com/questions/3969576/jquery-javascript-arrays. But since I am a complete beginner I have formulated the question wrong and didn't understand the answers either.... :(
After failing to implement the given solutions I did some more looking around I found out that I need to compare 6 arrays of possible choices and intersect them to finally display only the overlapping values.
So this is, hopely, a clearer formulation:
I have 6 questions/6 groups of radio buttons for answers. Each answer has multiple values (they can range from 1 to 38 items to be displayed in final 'advice'). I am collecting the values of checked radios in arrays. I get 6 arrays.
How do I intersect 6 arrays in order to get one final array containing only intersecting values form all 6 choices? How do I turn items of this final array into selectors?
Can someone please help me? Thank you!
My script looks now like:
(function($){
$.fn.checkboxval = function(){
var outArr = [];
this.filter(':checked').each(function(){
outArr.push(this.getAttribute("value"));
});
return outArr;
};
})
(jQuery);
$(function(){
$('#link').click(function(){
var valArr1 = $('#vraag1 input:radio:checked').checkboxval();
var valArr2 = $('#vraag2 input:radio:checked').checkboxval();
var valArr3 = $('#vraag3 input:radio:checked').checkboxval();
var valArr4 = $('#vraag4 input:radio:checked').checkboxval();
var valArr5 = $('#vraag5 input:radio:checked').checkboxval();
var valArr6 = $('#vraag6 input:radio:checked').checkboxval();
// var newArray = $.merge(valArr1, valArr2, valArr3, valArr4, valArr5, valArr6); <- test to see if I can merge them
// $('#output').text(newArray.join(',')); <- test to see if I can join them
//$("#output").html($("#output").html().replace(/,/gi, ',#diet')); <- test to see if I can append text so it looks like the selectors of divs I need to display later
// return false;
});
});
my form/inputs looks like:
<input name="vraag1" type="radio" value="1a,4,5,12,13,17a,18,19,22,23,24,26,27,28,29,30,33,38,6" class="radio advice" id="vraag1-0" /><label for="vraag1-0">ja</label>
<br />
<input name="vraag1" type="radio" value="1b,1,2,3,7,8,11,9,14,15,16,17,20,21,25,31,34,35,36,37,10,32" class="radio advice" id="vraag1-1" /><label for="vraag1-1">nee</label>
<br />
<input name="vraag1" type="radio" value="1c,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,17a,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38" class="radio advice" id="vraag1-2" /><label for="vraag1-2">maakt mij niet uit</label>
