flex string 怎么转换成 ArrayCollection

[{_id:0,FAcctGroupName:'科目',children:[{_id:"4dabf54ce631bfb8475d0f77",FAcctGroupName:"资产",children:[{_id:"4dabf54ce631bfb8485d0f77",FAcctGroupName:"流动资产"},{_id:"4dabf54ce631bfb8495d0f77",FAcctGroupName:"非流动资产"}]},{_id:"4dabf54ce631bfb84a5d0f77",FAcctGroupName:"负债",children:[{_id:"4dabf54ce631bfb84b5d0f77",FAcctGroupName:"流动负债"},{_id:"4dabf54ce631bfb84c5d0f77",FAcctGroupName:"非流动负债"}]},{_id:"4dabf54ce631bfb84d5d0f77",FAcctGroupName:"权益",children:[{_id:"4dabf54ce631bfb84e5d0f77",FAcctGroupName:"所有者权益"}]},{_id:"4dabf54ce631bfb84f5d0f77",FAcctGroupName:"成本",children:[{_id:"4dabf54ce631bfb8505d0f77",FAcctGroupName:"成本"}]},{_id:"4dabf54ce631bfb8515d0f77",FAcctGroupName:"损益",children:[{_id:"4dabf54ce631bfb8525d0f77",FAcctGroupName:"营业收入"},{_id:"4dabf54ce631bfb8535d0f77",FAcctGroupName:"营业成本及税金"},{_id:"4dabf54ce631bfb8545d0f77",FAcctGroupName:"期间费用"},{_id:"4dabf54ce631bfb8555d0f77",FAcctGroupName:"其他收益"},{_id:"4dabf54ce631bfb8565d0f77",FAcctGroupName:"其他损失"},{_id:"4dabf54ce631bfb8575d0f77",FAcctGroupName:"以前年度损益调整"},{_id:"4dabf54ce631bfb8585d0f77",FAcctGroupName:"所得税"}]},{_id:"4dabf54ce631bfb8595d0f77",FAcctGroupName:"表外",children:[{_id:"4dabf54ce631bfb85a5d0f77",FAcctGroupName:"表外科目"}]}]}]
我按照ArrayCollection的存储结构构造了一个字符串,就如上贴出的,上面字符串直接放在 new ArrayCollection()中是正确的,但是,如果是字符串该怎么办,不能new ArrayCollection(str)这样...............,该怎么办,求人指教

为什么要写成字符串呢，你new既然可以，那就new啊，或者你把这些数据写在xml里面，加载这个xml来给ArrayCollection赋值，一般都是写成xml的。
你这个应该是想做一个导航吧......

new ArrayCollection([{_id:0,FAcctGroupName:'科目'}]);这样是行,

但是

String str="[{_id:0,FAcctGroupName:'科目'}]";
new ArrayCollection(str);不行是错误的

除了存入xml中还有其他的办法没?

追答

ArrayCollection 的构造函数的参数不能是String型的，所以肯定是错误的。除了写在xml里面，我是没有别的办法了，不过写在xml里面多方便啊，想改的话只要改xml就可以了，要不还得再编辑AS3，还得再编译，多麻烦啊

追问

谢谢回答,我还是用xml了....
