I’m typing with my mobile phone and I don’t have access to a tool for writing the complete code easily, but look at this mistakes in your code: You must Add document. before any getElementById in your code. You must wrap visible between ” “: document.getElementById(‘bro’).style.visibility = “visible”; What is set (in set.setTimeout)? remove it … Read more
Ok, I know how much you loved my 10000 checkboxes so since I recently moved to 50000 checkboxes I figured it would be fun to post an answer (maybe I’ll get enough downvotes to keep me going till the ultimate target of 100000 checkboxes on a single page). I updated the HTML since last time … Read more
The event loop predates javascript.. but just by a tiny bit. The event loop was introduced to support progressive download of pictures in Netscape. And almost immediately it was also used to support early rendering where DOM elements are displayed on screen before all images are downloaded. At the time, other browsers displayed blank white … Read more
I’m getting my question from second hand research from mozilla’s documentation on the matter. Know I might understand better the intent if I was better in tune with W3C’s precedent but I have trouble finding and reading W3C’s intentions. The obsolete selectors-api2 spec says that the Selectors API definitions have been merged into the DOM … Read more
First of all if you want that something would happen you need to write that in the function. You already wrote variables, but you did nothing with them, so nothing could happen. Try this : <p id=”demo” onclick=”myFunction()”>Click me to change my HTML content (innerHTML).</p> <script> function myFunction() { document.getElementById(“demo”).innerHTML = “Paragraph changed!”; } </script> … Read more
The code seems to work but would makes strange html. Rows (tr elements) should contain cells (td elements). And your not iterating over your game_names array your just iterating from 0 to ten. See my example of your code below. var game_names = [ “first_game”, “second_game”, “third_game”, “fourth_game”, “fifth_game” ]; var parent = document.getElementById(“games”); for … Read more
This depends on what Element is and whether getAttribute is defined for it. If so, the question is: what does getAttribute do, if called with the parameter of “src”. For instance, if getAttribute is like this: function MyElement() { var that = this; var getAttribute = function(param) { return that.param; } } and Element is … Read more
This particular web page isn’t using <select> and <option>. That suggests to me that they are using some custom JavaScript to simulate a drop-down list using the illustrated <div> and <span> elements. In addition, they are using onselect rather than onclick to trigger event handlers. I can’t replicate your test case. However, I did make … Read more
You could use getElementById in case you have multipe nested images in different id’s. Then you could use getElementsByTagName to get the image elements and loop those using a for loop and storing the src in an array urls. var elms = document.getElementById(‘content’).getElementsByTagName(‘img’); var urls = []; for (var i = 0; i < elms.length; … Read more
The element you were trying to find wasn’t in the DOM when your script ran. The position of your DOM-reliant script can have a profound effect on its behavior. Browsers parse HTML documents from top to bottom. Elements are added to the DOM and scripts are (generally) executed as they’re encountered. This means that order … Read more
Since the question refers to a single element, this code might be more suitable: // Checks CSS content for display:[none|block], ignores visibility:[true|false] $(element).is(“:visible”); // The same works with hidden $(element).is(“:hidden”); It is the same as twernt’s suggestion, but applied to a single element; and it matches the algorithm recommended in the jQuery FAQ. We use … Read more
