Answer 1

According to this answer, you can add the condition within the for loop statement

Simply:

function refercheck(){
    var input_value = document.getElementById('refer').value;
    document.getElementById("valid").innerHTML = '';
    {% for i in refer if input_value == i.refercode %}
        $('#valid').append('Referred By {{i.username}}');
    {% endfor %}

Update: Jinja2 does not support break or continue statments

you have to use other ways to solve this problem

here is what came to my mind I didn't try the code but here is the idea.

function refercheck(){
    var input_value = document.getElementById('refer').value;
    refer = {{refer|safe}}

    for (i = 0; i < refer.length; i++) {
        document.getElementById("valid").innerHTML = '';
        if( input_value == i.refercode ){
            $('#valid').append('Referred By '+i.username);
            break;
        }
    }
}

if i.refercode and i.refercode does not work try i['refercode'] and i['refercode']
