control flow graphsimmediate post-dominator analysisWebsites today routinely combine JavaScript from multiple sources, both trusted and untrusted. Hence, JavaScript security is of paramount importance. A specific interesting problem is information flow control (IFC) for JavaScript. In this paper, we ...
再接下来我们要绑定数组中的一个对象的name属性到span上,由于当前的绑定上下文已经是数组了,所以我们可以直接使用数组元素的name属性来完成绑定 到这里,我们发现Binding Context随着Control Flow的使用,一层层向下延展开来,这样有一个好处,就是方便我们进行更细层次的绑定,语法更加简单。因为上下文已经随着foreach的指定而...
