更改链接的URL，具体取决于它们是否在移动设备上 [英] Change URL of a link depending on whether or not they are on mobile

问题描述

我有一个为移动和桌面用户显示的按钮，当前设置为tel:123-456-7890.这非常适合移动用户，但我希望桌面用户转至锚定链接#contact

I have a button that shows for mobile and desktop users, currently its set as tel:[phone]. This works great for mobile users, but I want Desktop users to instead go to an anchor link #contact

我会提到我无法更改按钮的类名，但可以设置ID.

I'll mention that I can't change the class name of the button but I can set an ID.

如果用户未设置JavaScript，我想将默认值更改为#contact锚标签.然后，如果确定为可移动，则将URL更改为tel:else锚标记.

I'd like to change the default to #contact anchor tag, in case users don't have javascript set. Then if determined to be mobile, change URL to tel: else anchor tag.

推荐答案

可以通过多种方式解决此问题.使用javascript，一个大概的想法是:我建议阅读这篇文章-> detecting-a-mobile-browser

THis problem can be solved in multiple ways. With javascript, a rough idea would be : I recommend reading this post -> detecting-a-mobile-browser

考虑到这一点，您可以仅使用该功能来检测用户是否为移动用户并更新链接

With this in mind, you can just use that function in order to detect whether the user is a mobile one or not and update the link

window.isMobile = function() {
  var check = false;

  return check;
};



if (isMobile()){
    document.getElementById("YOUR_BUTTON_ID").setAttribute("href","your mobile link");
   // Or use jquery like $("#YOUR_BUTTON_ID").attr("href,"your mobile link")
}

但是，如果您要使用js方法，我建议您做一些更通用的事情.例如，您可以通过自定义属性直接将移动href存储在按钮上，如果在移动设备上，则可以使用它替换实际的href值.这样，您将避免重复代码和逻辑

However, if you are to go with the js approach, I'd recommend doing something more generic. For example, you can store the mobile href on the button directly via a custom attribute , and just use that to replace the actual href value if on mobile. In this way, you would avoid duplicating code and logic
