//一级分类
var oaalFtype = "${base}/risen/pub/dictCombo.action?uuid=/DICT/OA/ASSETLIB/FTYPE&TYPE=jsn_grid";
initSelect("oaalFtype",oaalFtype);
//批次
var oaalBatch = "${base}/risen/pub/dictCombo.action?uuid=/DICT/OA/ASSETLIB/BATCH&TYPE=jsn_grid";
initSelect("oaalBatch",oaalBatch);
//监控一级分类
form.on(&#39;select(oaalFtype)&#39;, function(data){//2级联动
//二级分类初始化
var oaalStype = "${base}/risen/pub/dictCombo.action?uuid=/DICT/OA/ASSETLIB/FTYPE/"+encodeURI(data.value)+"&TYPE=jsn_grid";
initSelect("oaalStype",oaalStype);
