The approach you suggest is not guaranteed to give you the result you’re looking for – what if you had a tbody for example: <table id=”myTable”> <tbody> <tr>…</tr> <tr>…</tr> </tbody> </table> You would end up with the following: <table id=”myTable”> <tbody> <tr>…</tr> <tr>…</tr> </tbody> <tr>…</tr> </table> I would therefore recommend this approach instead: $(‘#myTable tr:last’).after(‘<tr>…</tr><tr>…</tr>’); … Read more
Assuming you have a button with the id button, try this example: $(“#button”).click(function() { $([document.documentElement, document.body]).animate({ scrollTop: $(“#elementtoScrollToID”).offset().top }, 2000); }); I got the code from the article Smoothly scroll to an element without a jQuery plugin. And I have tested it on the example below. <html> <script src=”https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js”></script> <script> $(document).ready(function (){ $(“#click”).click(function (){ $(‘html, … Read more
If you take advantage of how == works, you could simply create an object with a custom toString (or valueOf) function that changes what it returns each time it is used such that it satisfies all three conditions. const a = { i: 1, toString: function () { return a.i++; } } if(a == 1 … Read more
This is a trick, function openInNewTab(url) { window.open(url, ‘_blank’).focus(); } //or just window.open(url, ‘_blank’).focus(); In most cases, this should happen directly in the onclick handler for the link to prevent pop-up blockers, and the default “new window” behavior. You could do it this way, or by adding an event listener to your DOM object. <div … Read more
Use location.reload(). For example, to reload whenever an element with id=”something” is clicked: $(‘#something’).click(function() { location.reload(); }); The reload() function takes an optional parameter that can be set to true to force a reload from the server rather than the cache. The parameter defaults to false, so by default the page may reload from the … Read more
Update: Jan-2022 Using Proxy() is faster than using Object.fromEntries() and better supported const params = new Proxy(new URLSearchParams(window.location.search), { get: (searchParams, prop) => searchParams.get(prop), }); // Get the value of “some_key” in eg “https://example.com/?some_key=some_value” let value = params.some_key; // “some_value” Update: June-2021 For a specific case when you need all query params: const urlSearchParams = … Read more
Check out the built-in function encodeURIComponent(str) and encodeURI(str). In your case, this should work: var myOtherUrl = “http://example.com/index.html?url=” + encodeURIComponent(myUrl);
Note: Using stopPropagation is something that should be avoided as it breaks normal event flow in the DOM. See this CSS Tricks article for more information. Consider using this method instead. Attach a click event to the document body which closes the window. Attach a separate click event to the container which stops propagation to … Read more
Standard Method (no library) The arguments are stored in process.argv Here are the node docs on handling command line args: process.argv is an array containing the command line arguments. The first element will be ‘node’, the second element will be the name of the JavaScript file. The next elements will be any additional command line … Read more
Use new Date() to generate a new Date object containing the current date and time. var today = new Date(); var dd = String(today.getDate()).padStart(2, ‘0’); var mm = String(today.getMonth() + 1).padStart(2, ‘0’); //January is 0! var yyyy = today.getFullYear(); today = mm + “https://stackoverflow.com/” + dd + “https://stackoverflow.com/” + yyyy; document.write(today); This will give you … Read more
