Assuming you have something like this: <div id=”somecontent”><video …><p>Video Caption</p></div> You can use simple DOM scripting to select the element and replace its contents: <script> var element = document.getElementById(“somecontent”); element.innerHTML = “<audio><p>New Caption</p>” </script> You would then tie this replacement to the onclick event of an input or a link styled to look like a … Read more

This is called “mounting” in React. We also want to clear that timer whenever the DOM produced by the Clock is removed. This is … Read more
This error message means that you accessed the property “all” of the variable document, but this property is, let’s say, deprecated, so should not be used. The console says that you should use a method “getElementById”, which returns the element with given id, on which you can then proceed. To access the element by id … Read more
I believe it’s more like the second. Basically: Not necessarily in this order: The browser parses the HTML and creates a bunch of objects called The Document Object Model, or DOM. The browser parses the CSS. Each CSS block is made up of a selector and then a bunch of properties. For each CSS block, … Read more

These do different things. .closest(‘.DivB’) will traverse the DOM tree up until it finds an element that matches the selector (probably none). .parent().next() will do what it looks like it will do, find the parent then its next sibling. What you want is .closest(‘td’).find(‘.DivB’) and don’t worry about micro-optimizations. It won’t break when the DOM … Read more

The easiest way would be to use: document.getElementsByTagName(“*”).length Is there something necessary like the numerical coding for node types like: 1: for element-nodes 3: for text-nodes 9: for document-nodes? No. You could write a function which recursively loops over the children of every node (starting at the document) and testing the node type of each … Read more

Got it! I forgot to put .length after $titleArray and I used appendTo() instead of prependTo(). Although the code doesn’t look so elegant now. But it’s a good start. var $titleArray = $(‘.title’); for (var i = 0 ; i < $titleArray.length; i++){ var $imageWrapper = $($titleArray[i]).parent().prev(); $($titleArray[i]).prependTo($imageWrapper); }; solved DOM manipulation with JavaScript or … Read more
If your goal is just to remove a row as soon as its checkbox gets clicked, then the following snippet accomplishes that. Note that your checkboxes didn’t have the deleter class; I added that. $(‘.deleter’).click(function () { $(this).closest(‘tr’).remove(); }); <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js”></script> <div class=”table1″> <form> <table> <tr> <th>Primary</th> <th>Address</th> <th>Construction</th> <th>Town Grade</th> <th>Select All <br /> … Read more
