前端js代码

//增add: function () {    $('#SysResourceEdit').dialog({            href: SysResource.URL.inputUI(),            onLoad: function () {                $('#parentResource').combotree({                    onSelect: function (record) {                    },                    onChange: function (a,b) {                    },                    url: SysResource.URL.tree(),                    method: 'get',                    value:'0',                    panelHeight: 'auto'                });            }        })        .dialog("open");}复制代码
