推荐答案
您不能动态地改变输入的类型,因为IE不允许这一点,AngularJS必须是跨浏览器兼容。所以,即使你可能会看到改变的类型在源$ C $ C AngularJS显示不会把它捡起来 - 类型只计算一次,不能更改
You can't change input's type dynamically since IE disallows this and AngularJS needs to be cross-browser compatible. So even if you might see the changed type displayed in the source code AngularJS won't pick it up - type is only evaluated once and can't be changed.
请注意,同样的限制适用于jQuery的: jQuery的改变输入类型
Please note that the same restriction applies to jQuery: jQuery change input type
您只对动态类型的选项要么自定义指令(在这里你可以下载一个动态模板或prepare上即时DOM)或使用 NG-包括
包括包括谐音,其中输入类型是一个静态值。
You only options for dynamic types are either a custom directive (where you can download a dynamic template or prepare DOM on-the-fly) or using ng-include
to include include partials where the input type is a static value.
