我正在使用this插件为twitter-bootstrap-3中的表单的选择字段创建DualListBox。该表格是为编辑目的而创建的。所以我试图在右侧框中添加先前选择的值。并且还手动添加未选择的值。

为此,我从JSON收集了数据并手动设置了选项字符串。这是我的代码-

// Getting data related to the country of operations
    $.getJSON(country_of_operation_json_url)
        .done(function (data) {
            var options = '';

            for (var i = 0; i < data.length; i++) {
                var a = 1;
                for (var j = 0; j < port_ids.length; j++) {
                    // Appending "selected" attribute to the values which are already selected
                    if (port_ids[j] == data[i]["id"]) {
                        options += '<options value="' + data[i]["id"] + '" selected="selected">' + data[i]["port_iso"] + '</options>';
                        a = 0;
                    }
                }
                if (a == 1) {
                    options += '<options value="' + data[i]["id"] + '">' + data[i]["port_iso"] + '</options>';
                }
            }

            // Appending the options at the selected box of the dual box
            $("select#country-of-operation-edit").empty().append(options);

            // Loading Country of operating dual-box field
            $("#country-of-operation-edit").DualListBox();

        });


这是生成选择字段的html文件-

<div class="form-group row">
                    <label class="col-sm-2 form-control-label">Country of operation</label>
                    <div class="col-sm-10">
                        <select class="form-control" multiple="multiple" data-json="false" id="country-of-operation-edit">
                        </select>
                    </div>
                </div>


问题是该字段中没有显示任何值。这是屏幕截图-

我在这里找不到我在做什么错。如果这不是用值填充DualListbox的方法,还有其他方法吗?任何帮助将不胜感激。我在这里呆了几个小时。

编辑1:这是我的json-http://codebeautify.org/jsonviewer/cb7e1573

EDIT-2:要进行检查,您可以选择此值-

port_ids = ["41", " 47", " 61"]

最佳答案

options更改为option man :)

for (var i = 0; i < data.length; i++) {
                var a = 1;
                for (var j = 0; j < port_ids.length; j++) {
                    // Appending "selected" attribute to the values which are already selected
                    if (port_ids[j] == data[i]["id"]) {
                        options += '<option value="' + data[i]["id"] + '" selected="selected">' + data[i]["port_iso"] + '</option>';
                        a = 0;
                    }
                }
                if (a == 1) {
                    options += '<option value="' + data[i]["id"] + '">' + data[i]["port_iso"] + '</option>';
                }
            }
