如何监视人体数据jQuery中的属性更改? [英] How to monitor when the body 'data' attribute changes in jQuery?

问题描述

我的body标签中有data-segment属性，该属性由滑块更改.更改时，我需要基于此值触发一个函数.

I have data-segment attribute in my body tag that is changed by a slider. I need to trigger a function based on the value of this, when it is changed.

在这种情况下，我不确定如何附加事件侦听器吗?

I'm not sure how to attach an event listener in this case though?

推荐答案

`当DOM节点属性更改时，没有可靠的跨浏览器方式来接收事件.有些浏览器支持"DOM突变事件"，但您不应该依赖它们，您可以使用Google这个短语来了解该技术的不幸历史.

`There is no reliable cross-browser way to receive an event when a DOM node attribute is changed. Some browsers support "DOM mutation events", but you shouldn't rely on them, and you may Google that phrase to learn about the ill-fated history of that technology.

如果滑块控件未触发自定义事件(我认为大多数现代事件都将触发该事件)，那么最好的选择是设置一个setInterval()方法以轮询该值.

If the slider control does not fire a custom event (I would think most modern ones do), then your best bet is to set up a setInterval() method to poll the value.
