If statement not accepting variable value

Question

I have this code:

meJi = 33;
$.ajax({
type: "POST",
url: mega,
data: string,
beforeSend: function() {
    $('#loading').html("<img src='images/loading.gif'/>").fadeIn('fast');
},
complete: function() {
    $('#loading').fadeOut('fast');
},
success: function(msg) {
    loading_hide();
    f = (msg).length;
    if (f <= 1250) {
        alert("su busqueda no presenta resultados");
        code(3);

        else {
            $("#container").html(msg);
            fdemandados();
        }
    }
});
function code(ig) {
    console.log(img);
    meJi = ig;
}

$("#select_comprobar3").on('click', function(event) {
    tacuba = $("#amazon").val();
    ca = "2";
    dan = "g";
    if (meJi ==3) {
        avisobusqueda2 = $("#avisofiltro").html("zzzFiltro activado Busqueda por la palabra: " + tacuba + " - clic para quitar ").fadeIn('slow');
    } else {}
    if (!tacuba) {
        alert("Debe ingresar una palabra");
    } else {
        lor = tacuba;
        var page = "1";
        loadData(page, dan, lor);
    }
    event.stopImmediatePropagation();
    return false;
});

the problem is this:

if (meJi==3) {

I don't know why but meJi variable never changes to 3 so the conditional always assume that meJi is 33.

edit: Im change the conditional part but the problem still exist.

In this code it will never get to "3", but you are also comparing String with Integer. — Niels

@DaveNewton I am aware it returns true, but it's kinda nasty. — Niels

In

function code(ig){
  console.log(img);
  meJi = ig;
}

Should it not be console.log(ig);? How you have it would cause an error (with img not defined) and therefore, meJi would not get set.

This would NOT cause an error. It would just output undefined in the console.

@Orin yes, but this is not the question. Is another mistake.

@Steve If img is not defined it will throw a RefereneceError and prevent meJi from being set.

epascarello Over a year ago

@Steve It would throw ReferenceError: img is not defined error, not undefined. Unless I missed where it is declared. Meaning it would never set the variable to 3.

@aug it changes nothing. I am correct that error and the problem still exist.
