dom-events

I have an HTML page where several JavaScript, CSS and images files are referenced. These references are dynamically injected and user can manually copy the HTML page and the support files to another machine. If some JS or CSS are missing, the browser complains in the console. For example: Error GET file:///E:/SSC_Temp/html_005/temp/Support/jquery.js I need somehow these errors reported back to me on the inline JavaScript of the HTML page so I can ask user to first verify that support files are copied correctly. There's the window.onerror event which just inform me that there's a JS error on

On a web app I need to work with a lot of high-res images, which are dynamically added to the DOM tree. They are pre-loaded, then added to the page. It's one thing to detect when such an image has finished loading, for this I use the load event, but how can I detect when it has finished being rendered within the browser, using Javascript? When working with high resolution images, the actual painting process can take a lot of time and it's very important to know when it ends. I used requestAnimationFrame to do the trick. After image loaded it will be rendered during the next animation frame. So

I can easily create a html input field that has text already in it. But when the user clicks on the input field the text doesn't disappears but stays there. The user then has to manually remove the text to type. How can I create an input field where when the user clicks on the input field box the text then disappear? Nayish What you want to do is use the HTML5 attribute placeholder which lets you set a default value for your input box: <input type="text" name="inputBox" placeholder="enter your text here"> This should achieve what you're looking for. However, be careful because the placeholder

Need JavaScript or jQuery something to change text every some seconds... with user doing anything. Example: "Welcome" changes to "Salmat datang" changes to "Namaste" etc after 3 secs and loops back. Thomas Shields As others have said, setInterval is your friend: var text = ["Welcome", "Hi", "Sup dude"]; var counter = 0; var elem = document.getElementById("changeText"); var inst = setInterval(change, 1000); function change() { elem.innerHTML = text[counter]; counter++; if (counter >= text.length) { counter = 0; // clearInterval(inst); // uncomment this if you want to stop refreshing after one

If this is for a double-click: window.addEventListener("dblclick", function(event) { }, false); How can I capture a triple-click? This is for a pinned tab in Google Chrome. You need to write your own triple-click implementation because no native event exists to capture 3 clicks in a row. Fortunately, modern browsers have event.detail , which the MDN documentation describes as : A count of consecutive clicks that happened in a short amount of time, incremented by one. This means you can simply check the value of this property and see if it is 3 : window.addEventListener('click', function (evt)

I am working with an existing web app, in the app there are a variety of submit buttons on different forms, some using regular http post, some defining an onClick function, and some binding a js event handler to the button using a class on the element. What I want to do, is bind another event handler to these buttons by just adding a class to the buttons, but what I want to determine is will the new event handler be guaranteed to be executed, or could one of the form submit actions happen before it does meaning my new function isn't hit. The example scenario is I want to add a class to these

We all know that you can simulate click or any other event on an element using one of these ways: $('#targetElement').trigger('eventName'); $('#targetElement').click(); I have encountered a situation in which, I should know how an element is clicked. I should know if it's been clicked automatically via code, or by pressing mouse button. Is there anyway I can do it without hacks or workarounds? I mean, is there anything built into browsers' event object, JavaScript, or jQuery that can tell us whether click has been initiated by a human action or by code? Try this: $('#targetElement').click
