easy ui combobox getValue 获取不到值问题

必须设置属性showblank: true，否则只能从onSelect事件中获取

$("#ddlType").combobox({        valueField: 'id',        textField: 'text',        editable: false,        mode: 'local',        data: defultlist,        //showblank: true        onSelect: function (row) {            $("#ddlType").val(row.id);          });

 

combobox 多选案例

var JsonData = $("#hdWTData").val();    var defultlist = [];//    if (JsonData != "") {        JsonData = JSON.parse(JsonData);        for (var i = 0; i < JsonData.length - 1; i++) {            defultlist.push({ "id": JsonData[i].BZlevelID, "text": JsonData[i].BZlevelName });        }    }    $('#BZlevelID').combobox({        valueField: 'id',        textField: 'text',        editable: false,        //disabled: blDisabled,        //required: true,        showblank: true,        //validType: 'cmbrequired',        multiple: true,        formatter: function (row) {            var opts = $(this).combobox('options');            return '  ' + row[opts.textField]        },        mode: 'local',        data: defultlist,        onSelect: function (row) {            var opts = $(this).combobox("options");            var objCom = null;            var children = $(this).combobox("panel").children();            $.each(children, function (index, obj) {                if (row[opts.valueField] == obj.getAttribute("value")) {                    objCom = obj;                }            });            if (objCom != null && objCom.children && objCom.children.length > 0) {                objCom.children[0].checked = true;            }        },        onUnselect: function (row) {            var opts = $(this).combobox("options");            var objCom = null;            var children = $(this).combobox("panel").children();            $.each(children, function (index, obj) {                if (row[opts.valueField] == obj.getAttribute("value")) {                    objCom = obj;                }            });            if (objCom != null && objCom.children && objCom.children.length > 0) {                objCom.children[0].checked = false;            }        }    });    if (defultlist.length > 0) {        $("#BZlevelID").combobox("select", "3");        $("#BZlevelID").combobox("select", "4");        $("#BZlevelID").combobox("select", "5");    }
