Javascript Vue JS如何绑定复选框？

如何使用vue js表达式绑定复选框值？下面是filteroptions对象的数据，我将该值绑定到我在下面输入的#html1

我想知道的是如何将选中的值绑定到#html2？从#html1中的drpdown菜单中选择的值

正如您在html2上看到的我的过滤器，它不是动态的

多谢各位

html1

您应该绑定复选框，该复选框接受布尔值。因此，在您的情况下，它可能是

我不确定我是否完全遵循了您的代码，特别是setFilters（）方法，但Vue的原理是将所有页面状态封装在一个模型中，然后html2只查看与复选框双向绑定的模型值。这有意义吗
