CustomEvent.detail “tainted”?

由 淺唱寂寞╮ 提交于 2020-01-15 07:02:19
问题 I'm developing a Chrome extension to add convenience to a website. I have access to the page's DOM, but I also need to interact with the "first-party" JS on that page, which I cannot do from my extension. I can inject arbitrary tags into the page (most notably also <script> tags), but since escaping strings like { html: '<div onclick="doSomething(this, \'someName\')"></div>' } is a real pain, I'd like to keep the injected code at an absolute minimum.

How to determine if browser supports properties on event object?

问题 Some touch-enabled browsers (such as Mobile Safari) have a scale and rotation property available on their event object for events such as touchmove . I can detect support for the scale property like so... document.body.addEventListener("touchmove", function(event) { var supportsScaleProperty = !!event.scale; }); However, is there a way to detect it without having to bind a listener and then look for the property in the callback? For example, if this worked? var supportsScaleProperty = !!(new

问题 I'd like to delete an object after it's done animating with a CSS transition, but I'm not able to use a JavaScript library. How do I detect when the animation is done?
