Question

我有一个html字符串，我需要放入一个输入选择，但它超出了输入选择的位置......我想，看看我正在构建的选项变量？在任何一个类.product之后它需要在下一个选择内部...请告知。

    $(".product").change(function(){

        //get selected option of the select that changed
        var selected = $(this).val();
        //then create the url to reference the value of the selected option (product id)
        var url = "/order/getpricing/" + selected;

        //remove all options from that nearby select statement
        $(this).next('select').children().remove();

        var pricelist = $(this).next('select');

        $.getJSON(url, function(data, pricelist){

            var options = '';
            for(n = 0; n < data.length; n++){
                options += '<option value="' + data[n].volumeID + '">' + explainPricing(data, n) + '</option>';
                //setMeGlobal(options, "options");
                }

                $("#"+pricelist).html(options);


                //TODO NEXT: SOMEHOW ADD OPTIONS TO THE SELECT!


        });

        $(this).next('select').html = options;

    });

尝试尽可能多地重复使用pricelist变量。它可以自动提供给你的ajax处理程序，而不必传递它：

$(".product").change(function(){

    //get selected option of the select that changed
    var selected = $(this).val();
    //then create the url to reference the value of the selected option (product id)
    var url = "/order/getpricing/" + selected;

    var pricelist = $(this).next('select');

    //remove all options from that nearby select statement
    pricelist.find('option').remove();

    $.getJSON(url, function(data) {

        var options = '';
        for(n = 0; n < data.length; n++){
            options += '<option value="' + data[n].volumeID + '">' + explainPricing(data, n) + '</option>';
            //setMeGlobal(options, "options");
        }

        pricelist.html(options);
    });
});

如何在JQuery中使用变量遍历范围？
