工作总结

 var LoadDownData = function() {
        $.ajax({
            type:‘post‘,
            url:‘@Url.Action("QuestionType","Question")‘,
            dataType: ‘json‘,
            contentType: ‘application/json; charset=utf-8‘,
            success: function(data) {
                $(‘#selectType‘).combobox({
                    valueField: ‘id‘,
                    textField: ‘text‘,
                    panelHeight: 400,
                    data: data
                });
            }
        });
    };

  function Append() {
        if (EndEditing()) {
            editButtonState = true;
            var myDate = new Date();
            var currentDate = myDate.getFullYear() + "-" + (myDate.getMonth() + 1) + "-" + myDate.getDate();

            $("#grid").datagrid(‘insertRow‘, { index: 0, row: { PROBLEM_TIME: currentDate, ANSWER_TIME: currentDate} }); //在这里给默认值,PROBLEM_TIME是Filed的名称，后面跟上值

            editIndex = 0;
            $("#grid").datagrid(‘selectRow‘, editIndex)
                .datagrid(‘beginEdit‘, editIndex);
        }
    }

{
            field: ‘TYPE‘,
            title: ‘类型‘,
            width: 100,
            align: ‘left‘,
            formatter: function(value, row, index) {
                if (row.TYPE != "" && row.TYPE != null) {
                    return row.TYPE;
                }
                return "";
            },
            editor: {
                type: ‘combobox‘,
                options: {
                    valueField: ‘id‘,
                    textField: ‘text‘,
                    data: null,//写到这里的话，直接写数据
                    url:‘@Url.Action("QuestionType","Question")‘//这里写个URL它自己会去请求
                }
            }
        }

 var _jhmc = $(‘#grid‘).datagrid(‘getEditor‘, { index: editIndex, field: ‘WELL_COMMON_NAME‘ });

获取特定的编辑器，options参数有2个属性：
index：行索引。
field:字段名。 
示例:

// get the datebox editor and change its value
var ed = $(‘#dg‘).datagrid(‘getEditor‘, {index:1,field:‘birthday‘});
$(ed.target).datebox(‘setValue‘, ‘5/4/2012‘);

$(ed.target).datebox(‘setValue‘, ‘5/4/2012‘);

CommUtils.getQueryString = function (name) {
    var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
    var r = window.location.search.substr(1).match(reg);
    if (r != null) return r[2]; return null;
}

 //回车键处理
        $(document).keydown(function (event) {
            if (event.keyCode == 13) {//13是回车键
              　　//do somthingreturn false;//注意：必须要return false,因为页面中其他控件可能会监听回车键，这样子避免其他事件的触发
            }
        });
