I have added the following polyfill to Array in the beginning of my project: if (!Array.prototype.find) { Array.prototype.find = function(predicate) { if (this === null) { throw new TypeError('Array.prototype.find called on null or undefined'); } if (typeof predicate !== 'function') { throw new TypeError('predicate must be a function'); } var list = Object(this); var length = list.length >>> 0; var thisArg = arguments[1]; var value; for (var i = 0; i < length; i++) { value = list[i]; if (predicate.call(thisArg, value, i, list)) { return value; } } return undefined; }; } This works perfectly

I am using this preg_match string preg_match('/Trident/7.0; rv:11.0/',$_SERVER["HTTP_USER_AGENT"] to detect IE11 so I can enable tablet mode for it. However it returns "unknown delimiter 7". How can I do this without PHP complaining at me? Is this really a regular expression or just a literal string? If it's just a string, you can use the strpos function instead. if (strpos($_SERVER['HTTP_USER_AGENT'], 'Trident/7.0; rv:11.0') !== false) { // your code } If it's a regular expression, you must escape special characters like / and . EDIT: You can see in the comments of this answer that the code

This question already has an answer here: ToLocaleDateString() changes in IE11 5 answers I've ran into a possible bug with IE where calling the JavaScript . length function returns a value that is off by 1 if/when the string was derived from .toLocaleString() . var d = new Date(); var locale = navigator.language; var month = d.toLocaleString(locale, { month: "long"}); // month.length will return the length of the month string +1 //(eg: if month = "March", month.length will return 6.) Interestingly, the code example of above will return true (in IE) for the following: (month[0] should be "M")

I don't know is that an issue or bug, but when I use overflow: hidden , selecting the text and moving the cursor to the page bottom in IE, the page is scrolling (I tried IE9-IE11)! When I use Firefox/Opera/Chrome/Safari the page isn't scrolling... I have to use overflow: hidden , but it has an odd behavior in IE. So, my question is: how can I avoid page scrolling in IE? Use -ms-scroll-limit: 0 0 0 0; to prevent any scrolling whatsoever in IE 10+. For older browsers you can write a workaround using JavaScript. Example of CSS and JavaScript: body { overflow: hidden; -ms-scroll-limit: 0 0 0 0; }
