问jQuery .inArray()总是真的吗？

$("#select-by-color-list li").hide();

// get the select
var $dd = $('#product-variants-option-0');

if ($dd.length > 0) { // make sure we found the select we were looking for

    // save the selected value
    var selectedVal = $dd.val();

    // get the options and loop through them
    var $options = $('option', $dd);
    var arrVals = [];
    $options.each(function(){
        // push each option value and text into an array
        arrVals.push({
            val: $(this).val(),
            text: $(this).text()
        });
    });




};

//This is where it is returning true...


if($.inArray('Aqua', arrVals)) {
    $("#select-by-color-list li#aqua").show();
    };
    if($.inArray('Army', arrVals)) {
    $("#select-by-color-list li#army").show();
    };
