Ext 要讲json拼成Ext的datagrid格式的字符串

var nodeInfo = Ext.JSON.decode(['{total:1,', 'result:[{cname:"', treedata.cname,  '",cidver:"', treedata.cidVer, '",supplier:"',treedata.supplier, '",responsibleName:"', treedata.responsibleName,  '", cmpNo: "', treedata.csymbol,'", quality: "', treedata.quantity, '", weight: "', treedata.weight,'"}]}'].join(''), true);

一定要记得拼上=、=！写此贴来告诫自己别犯低端错误。
