问题 I am using HighCharts together with Python to dynamically create charts. All works fine, however I get cannot read property "0" of undefined exception under IE8. Unfortunetly my client want it to work under IE8 as well. So heres the code of the main function: function generateChart(series) { var chart = new Highcharts.Chart({ chart: { renderTo: 'company_chart', }, xAxis: { type: "datetime", }, yAxis: [{ title: { text: "T1", }, },{ title: { text: "T2", }, }, opposite: true, }], plotOptions: {

问题 I'm trying to make the background-color of a tr opaque with this CSS: .faded{ background-color: red; height: 100px; opacity: 0.4; filter: alpha(opacity=50); } Here is my test HTML: <table> <tr class="faded"> <td><div>testtesttesttestt</div></td> <td><div>testtsttesttesttt</div></td> </tr> </table> Everything works fine in IE9,10 FF24 Chrome 31+, but not in IE11.

问题 This is an annoying problem, and I don't suppose that it's only IE that has this problem. Basically I have a Node.js server, from which I am making cross-domain calls to get some JSON data for display. This needs to be a JSONP call and I give a callback in the URL. What I am not sure is, how to do this? So the website (domainA.com) has an HTML page with a JS script like this (all works fine in Firefox 3): <script type="text/javascript"> var jsonName = 'ABC' var url = 'http://domainB.com:8080

问题 When the user edits a contenteditable div , and press some keys, I would like to override the default behavior. For instance, I want to insert a normal line break when the user press ENTER. I do that using document.execCommand("insertText",...) This is the only way I have found so far to make this action undoable and redoable by the user. <div id="editor" contenteditable="true" style="white-space:pre-wrap"> Some text.... </div> <script> $("#editor").keydown(function(evt){ console.log(evt

问题 In javascript is there any difference between using element.style.setAttribute('width', '150px'); and element.style.width = '150px'; ? I have seen that keywords won't work with the first way (like this), but for non-keyword attributes is there a difference? 回答1: Both are perfectly valid. Can you give some examples which doesn't work in second way? Are you aware that attribute names needs to be camelcased first? E.g. element.style.marginTop instead of incorrectly element.style.margin-top . The

问题 So I'm trying to display images as big as possible with no cropping on any screen size. This means height: 100%; width: auto in landscape and width: 100%; height: auto in portrait . I'm serving up images that are big enough to fill retina iPads so pretty much every screen size will be scaling the images down. It does this fine in every browser & orientation except Internet Explorer & Firefox in landscape mode, leaving them far too big for pretty much every screen. This is only in landscape,

问题 I have already gotten my project to work on with async/await in every other browser, but apparently its not compatible in IE. (async function () { try { await getLayers(); } catch (err) { console.error(err) } }()); which calls my other function: async function getLayers() { try { $.when( await $.getJSON('http://' + ipAddress + '/api/Barriers/barrierGeoJSON', function (data) { createLayer(data[0].row_to_json, 'Barrier'); }), await $.getJSON('http://' + ipAddress + '/api/DistPoints
