Question

When a user messages another user. They can pick which type of profile to send to. (Common or Manager)… I’m checking in the backend which profile to send it to with “recipient_type”, How do I get my autocomplete to choose the hidden radio button for me?

The autocomplete looks like this:
To: John Doe - Manager
or
To: John Doe

template:

<div class="hide">
     <input type="radio" id="id_recipient_type" name="recipient_type" value="0" />
     <input type="radio" id="id_recipient_type" name="recipient_type" value="1" />
</div>
<div class="inline-block">
     <label for="id_omnibox"></label>
     <input type="hidden" name="recipient_username" id="id_recipient_username" />
     <input id="message-to" class="required input-text" style="width: 145%;"name="omnibox" placeholder="Search for user..." autocomplte="on" type="text" />
</div>

script:

$(document).ready(function(){
    $.get('/autocomplete/message/', function(data) {
        var completions = new Array();
        var dict = JSON.parse(data, function(key, value) {
            completions.push(key);
            return value;
        });
        $('#message-to').autocomplete({
            source: completions,
            minLength: 1,
            select: function(value, data){
                $('#id_recipient_username').val(dict[data.item.value])
                split_string = data.item.value.split("- ");
                $('#id_recipient_type_'+(split_string[1]=="Manager"?"1":"0")).attr('checked', true);
            }     
        });
    });
});

It seems that in order to your code to work you need to change or:

<div class="hide">
     <input type="radio" id="id_recipient_type_0" name="recipient_type" value="0" />
     <input type="radio" id="id_recipient_type_1" name="recipient_type" value="1" />
</div>

Radio boxes IDs. or:

$('#id_recipient_type[value="'+(split_string[1]=="Manager"?"1":"0")+'"]').attr('checked', true);

The jquery selector to #id_recipient_type[value="1"] or #id_recipient_type[value="0"].

I’d ratter use the first solution, since in html ids should be unique.

You need to solve a problem stated by kmfk with your split where it throws an error when don’t find the ' - ' string, so change:

split_string = data.item.value.split("- ");

To:

split_string = 'John Doe - Manage'.match(/ - (Manager)$/)
split_string = split_string != null ? "0" : "1";
