问题 I have the following Content Security Policy value="default-src 'self' style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval' http://svc.webspellchecker.net; img-src 'self' data: https://s3.amazonaws.com; frame-src 'self' *.salesforce.com *.force.com;" This works fine in Chrome and Firefox. In Edge it is not running because we have some inline scripts (ie onClick="foo() ). My understanding is the the default-src sets the defaults and the script-src should override

问题 I have a memory "leak" problem in Microsoft Edge browser. When I run a memory profiling session and take several snapshots, I see the memory between snapshot being freed. but the total memory consumption keep growing (see image). The memory difference between snapshots are an iframe being add and then removed from the DOM. How is this possible ? 回答1: I have been using the Edge memory profiler to try to test memory leaks with an iFrame as well. We found that the Edge profiler itself leaks

In IE11 and Edge, however, it doesn't work in the second scenario. What's going on? 回答1: IE appears to be treating all unknown elements as being the same element type. If you remove the bar type selector, you'll

问题 The following works fine in Chrome and Firefox, however in Edge it will alert NaN no matter the input document.querySelector('button').addEventListener('click', function(){ alert(document.querySelector('input').valueAsNumber); }); <input type='number' value='34'> <button> Alert number </button> Now, I am not asking how to fix this (using parseFloat(el.value) does that trick), I am asking however what Edge did implement valueAsNumber for then if the most basic function doesn't seem to work. As

问题 I'm currently working on a project, where I have to generate a report on a button click using jsPDF. The code works perfectly fine in Google Chrome and Mozilla Firefox but doesn't work on Microsoft Edge. The PDF document loads in an iframe in the background but the page is white and blank. Can anyone suggest a solution for displaying the PDF correctly in Microsoft Edge? Note: I cannot share the code because it causes copyright infringement. I'm sorry. Also, the debugger shows no such

问题 Is there a reliable, programmatic way to determine that Microsoft Edge is the default browser? I know one option would be to use the IApplicationAssociationRegistration::QueryCurrentDefault method to return the default application registered for http. It's unclear that the ProgID returned by this call is a fixed string though so it may not be the best way to verify that Edge is indeed the default browser. 回答1: Use the following code snippet. Haven't tested with Firefox or any of the other

问题 I'm using a code from here to paste images from clipboard on a page. It works fine in all browsers (Chrome, Firefox, Edge and Opera). The problem is: when the image is a PNG or GIF with alpha channel (transparent areas), the alpha becomes black in Firefox and Edge. Here's the code snippet (or jsfiddle if you prefer): document.getElementById('pasteArea').onpaste = function (event) { // use event.originalEvent.clipboard for newer chrome versions var items = (event.clipboardData || event
