Question

这是我目前的专栏模型：

   colModel: [
                    { name: 'LastName', index: 'LastName', width: 120, align: 'center' },
                    { name: 'FirstName', index: 'FirstName', width: 120, align: 'center' },
                    { name: 'MiddleName', index: 'MiddleName', width: 120, align: 'center' },
                    { name: 'DOB', index: 'DOB', width: 100, align: 'center' },
                    { name: 'id', index: 'id', align: 'center', hidden: true },
                    { name: 'checked', index: 'checked', align: 'center', hidden: true },
                    { name: 'courtType', index: 'courtType', align: 'center', editable: true, sortable: false, width: 100 },
                    { name: 'CaseNumber', index: 'CaseNumber', align: 'center', editable: true, sortable: false, width: 100 },
                    { name: 'CourtFileNumber', index: 'CourtFileNumber', align: 'center', editable: true, sortable: false, width: 100 },
                    { name: 'WarrantDocket', index: 'WarrantDocket', align: 'center', editable: true, sortable: false, width: 100 },
                    { name: 'Sentencing', index: 'Sentencing', align: 'center', editable: true, sortable: false, width: 100 },
                    { name: 'notes', index: 'notes', align: 'center', editable: true, sortable: false, width: 400 },

                    { name: 'name', index: 'name', width: 200,
                         sortable: true,
                         align: 'center',
                         editable: true,
                         cellEdit: true,
                         edittype: 'select',
                         formatter: 'select',
                         editoptions: { value: getAllSelectOptions() }
                     }
                  ],

这给了我一个来自getAllSelectOptions（）的下拉列表。

function getAllSelectOptions() {

    var states = { '1': 'Alabama', '2': 'California', '3': 'Florida',
        '4': 'Hawaii', '5': 'London', '6': 'Oxford'
    };
    return states;
}

有没有办法根据ID和webmethod调用（或其他方式）为每一行获取不同的列表？

var createCourtGridURL = AdminPath + "WebMethods/Kernel/Court.asmx/GetGetdData";

var jqGridDataURL = AdminPath + "WebMethods/Kernel/Court.asmx/GetSelectData";

            var html, errorInfo, i, errorText = textStatus + '\n' + errorThrown;
            if (jqXHR.responseText.charAt(0) === '[') {
                try {
                    errorInfo = $.parseJSON(jqXHR.responseText);
                    errorText = "";
                    for (i = 0; i < errorInfo.length; i++) {
                        if (errorText.length !== 0) {
                            errorText += "<hr/>";
                        }
                        errorText += errorInfo[i].ExceptionType + ": " + errorInfo[i].Message;

                    errorText = html[1];
                } else {
                    errorText = jqXHR.responseText.replace(/\n/, "<br>");
                }

您已经使用dataUrl。 jqGrid从4.5.3开始支持dataUrl。因此，您可以将dataUrl定义为回调，从而获取树参数rowid，value，columnName。因此，您可以从dataUrl返回包含rowid作为参数的URL。如果对dataUrl的调用因不同的行而异，则可以实现您的要求。

具有行特定下拉列表的JqGrid？
