select dropdown option from js

[oivanr]

Hi,
I am working in a form that get information of students. In this form I have between another, two select menu (dropdown). The first is about departaments (13_46) and, when I make a choice, populate a second one (13_47) based on the value selected in the first.
To edit the information I call all the data through an ajax call. The data is displayed inside the proper fields but I have problem with first dropdown (13_46) it doesn’t display the option text.
I assign the value and I tried to select the option inside a js script. I had use these:
a) $(‘.quform-field-13_46’).val().prop(‘selected’,true);
b) $(‘.quform-field-13_46’).filter(value=noDepto).prop(‘selected’,true);
c) if ($(‘.quform-field-13_46’).val() == noDepto){$(‘.quform-field-13_46’).prop(‘selected’,true)};
But nothing works.
I am not able to use the change() option because if I use it the next dropdown (13_47) doesn’t recognize the selected value, The (13_47) is working fine using this:
d) $(‘.quform-field-13_47’).val(valores[0][‘slg08_MuniNac’]).change();
Thanks in advance for your help,
