如何捕获iOS Safari事件在Javascript中的文本选择更改？ [英] How to capture iOS Safari event on text selection change within Javascript?

问题描述

以下情况：在iOS Safari上选择文字（允许假设普通html页面）时，会发生蓝色叠加，表示您已选择特定的段落。此外，您可以更改该选项，以更正您的初始选择区域。当选择区域更改完成时，我有兴趣捕获该事件。是否可能（当是，如何？）在Javascript中捕获这样的事件？提前Thx。

Following scenario: When selecting text on iOS Safari (lets assume a "normal" html page) an blue overlay occurs, indicating that you have selected a specific passage. Furthermore, you are able to change that selection, in order to correct your initial selection area. I'm interested in capturing exactly that event, when selection area change is done. Is it possible (when yes, how?) to catch such an event within Javascript? Thx in advance.

推荐答案

Mobile Safari支持 selectionchange 事件，它在文档节点：

Mobile Safari supports the selectionchange event, which fires on Document nodes:

document.addEventListener("selectionchange", function() {
    alert("Selection changed!");
}, false);
