材质2.0.0-beta.3 md滑块不拖动 [英] Material 2.0.0-beta.3 md-slider not dragging

问题描述

希望这是一个愚蠢的问题.

Hopefully, this is a stupid question.

我刚刚在为雇主创建的项目中添加了md滑块. (因此我没有代码表示抱歉)

I just added a md-slider to a project I am building for my employer. (thus I have no code to show sorry)

我将MdSliderModule导入到我正在使用的模块中.在我想要的模板中添加了标签.它出现了，看起来不错，但不会拖动.我可以单击它来更改其值，但不能拖动它.

I Imported MdSliderModule into the module I'm working in. Added the tag in my template where I wanted it. It showed up and looks great but won't drag. I can click on it to change its value but I can't drag it.

我错过了什么吗? Angular是否有我需要导入的该组件使用的拖动模块?其他人看到了吗?

Am I missing something? Does Angular have a Dragging module this component uses that I need to import? Has anyone else seen this?

我们正在使用:

• 角^ 4.0.2
• 材料2.0.0-beta.3

我想尝试的任何帮助或建议都将有所帮助.预先感谢您的宝贵时间.

Any help or suggestions of things for me to try will be helpful. Thank you in advance for your time.

推荐答案

在发现我没有安装Hammer.js之前，我遇到了完全相同的问题.

I had exactly the same problem until I discovered that I hadn't installed hammer.js.

npm install --save hammerjs

然后在您的angular-cli.json文件的scripts数组中添加Hammerjs作为依赖项:

then add hammerjs as a dependency in the scripts array of your angular-cli.json file:

 "scripts": [
    //possibly other scripts here...
    "../node_modules/hammerjs/hammer.min.js"
  ],
 ...

希望这可以解决问题-重新编译所有内容以确保更改生效

Hopefully this will resolve the issue - recompile everything to be sure that changes take effect
