示例

限定在指定文件中搜索

import javascript
from MethodCallExpr call
where call.getFile().getBaseName() = "string-manipulations.js"
select call

递归寻找使用location的表达式

import javascript
Expr useLocation(Expr call) {
    call.getAChildExpr().toString() = "location" and result = call
    or call = useLocation(result.getAChildExpr())
}
from MethodCallExpr call, int i
where call.getFile().getBaseName() = "string-manipulations.js"
select call, useLocation(call.getArgument(i))
