我有一个小问题.我正在使用REST/JS来填充下拉框,这需要首先查找列表中的列.

//Product Model Cascade
document.getElementById("productDD").onchange = function() {
    var prod = this.options[document.getElementById("productDD").selectedIndex].text;
    var select = document.getElementById("productModelDD");
    $(select).empty();


    var call2 = $.ajax({
        url: _spPageContextInfo.webAbsoluteUrl + "/_api/Web/Lists(guid'bb392616-24ee-47e2-9365-f17400348373')/Items", //the list
        type: "GET",
        dataType: "json",
        headers: {
            Accept: "application/json;odata=verbose"
        }

    });
    call2.done(function(data, textStatus, jqXHR) {
        var select = document.getElementById("productModellDD");
        for (index in data.d.results) {
            var parent = data.d.results[index].AT_ARMATECproducts; //Lookup column 
            console.log("parent var: " + parent);
            if (parent == prod) {
                var op = document.createElement("option");
                op.text = data.d.results[index].Title;
                op.value = data.d.results[index].Title;
                select.appendChild(op);
            }

        }
    }); …
