对象创建com对象并设置其字段

创建com对象并设置其字段

AH create|onEnd,threadid)[画数蕙优码]

使用异步方式生咸Com对象.

薑教onEnd[Optional :Function.回调醱L在5帧勺象成功生感后撫行*threadid冋选聲数]:String內部线程忆.如本参数为false,表示生成5呦过程不会异步调用函数

示例

(n ew Ap p)

.create( 〃fun ction (com) {// 被成功创建的对象coml in b.Ajax("ListL in ksql .ashx", n ul l , fun cti on (rsp) {var obj=_.un serial ize(rsp);for (i=0; i<obj.record s. l en gth; i++) {var rec=obj.record s[i];var items=obj.records;items[i]. id=rec. id;items[i].capti on=rec.n ame;
