IE input event for contenteditable?

由 心已入冬 提交于 2019-12-19 17:24:59
问题 I am wondering if there is a polyfill to support the contenteditable input event in IE11 ? I am specifically talking about this event: http://jsfiddle.net/ch6yn/ Which fires whenever a change happens on a contenteditable div regardless of the source (e.g. copy/paste/drag/drop/type etc). <div contenteditable="true" id="editor">Please type something in here</div> <script> document.getElementById("editor").addEventListener("input", function() { alert("input event fired"); }, false); </script>

How do I make Object.entries available in TypeScript? [duplicate]

问题 This question already has answers here : ES7 Object.entries() in TypeScript not working (3 answers) Closed 2 years ago . In my angular-cli-built app (which is currently using TypeScript 2.0.3) I want to be able to use this decomposition-based iterator: for (let [key, value] of Object.entries(obj)) { } What do I have to do in order to have it recognized: upgrade TypeScript? use a polyfill? if so: how do I import it - in individual .ts files or in a config file to make it globally available?

Why is the Temp.prototype on the MDN Object.create polyfill set to null?

由 烈酒焚心 提交于 2019-12-19 04:23:10
问题 Why does the MDN polyfill for Object.create have the following line: Temp.prototype = null; Is it so that we avoid maintaining a reference to the prototype argument enabling faster garbage collection? The polyfill: if (typeof Object.create != 'function') { Object.create = (function() { var Temp = function() {}; return function (prototype) { if (arguments.length > 1) { throw Error('Second argument not supported'); } if (typeof prototype != 'object') { throw TypeError('Argument must be an

I tried commenting web-animations polyfills but no luck. polyfill.ts /** * This file includes polyfills needed by Angular

Whats the best JSON JavaScript polyfill

由 自古美人都是妖i 提交于 2019-12-13 21:40:45
问题 I am looking for a JSON polyfill (for JSON support in older browsers) that I can use in some JavaScript I'm writing. I've looked and found JSON2 and JSON3 are quite popular and I've read that JSON3 is meant to be a drop in replacement for JSON2 but I was wondering if these are the best polyfills out there? The only problem I have with JSON3 is that when I run the google closure lint checks over the JSON3 library it complains about for loops not defining a body: If this if/for/while really

Useless function in Google Analytics?

由 断了今生、忘了曾经 提交于 2019-12-13 19:05:26
问题 I was looking through Google Analytics, and I came across this function (pretty-printed for readability): ha = function(a) { var b = []; if (Array.prototype.indexOf) return a = b.indexOf(a), "number" == typeof a ? a : -1; for (var c = 0; c < b.length; c++) if (b[c] === a) return c; return -1 }, This looks like an Array.prototype.indexOf polyfill. Trouble is, instead of the var b = this; you'd expect, there is instead var b = []; . I can't find any circumstance in which this would not return
