$("select option[value*='Sold Out']").prop('disabled',true);
        ?

According to edit

根据编辑

$('#previous_select').on('change', function() {
   // after creating the option
   // try following
   $("select option[value*='Sold Out']").prop('disabled',true);
});

function lockDownDropDownList(ddlName) {
    ddlName = "#" + ddlName;
    var chosenValue = $(ddlName).val();

    var downDownListItems = $(ddlName).children('option').map(function (i, e) {
        return e.value || e.innerText;
    }).get();

    downDownListItems.forEach(function (item) {
        if (item != chosenValue)
        {
            $("select option[value*='" + item + "']").prop('disabled', true);
        }
    });
}

In case anyone wants to be able to disable a drop down list by text instead of value, here's what I did:

如果有人希望能够通过文本而不是值禁用下拉列表，这就是我所做的：

$("#DDL option").filter(function () {
    return $(this).text() === "Text 1" ||
           $(this).text() === "Text 2" ||
           $(this).text() === "Text 3";
}).prop("disabled", true);
