dhtml

问题 I'm trying to add dhtml to the div with the id upload_results. That should work without replacing the current content in the div. The Code: (interesting part is at the bottom) <script language="JavaScript"> function do_show() { $("#webcamContainer").fadeIn(''); } webcam.set_hook( 'onComplete', 'my_completion_handler' ); function do_upload() { upload to server document.getElementById('upload_results').innerHTML = '<div>Uploading...</div>'; webcam.upload(); } function my_completion_handler(msg)

问题 I've inherited a project I'm working on and I'm updating some jquery animations (very little practice with jquery). I have a div I need to add and remove the style attribute from. Here is the div: <div id='voltaic_holder'> At one point in the animation I need to add a style to it: <div id='voltaic_holder' style='position:absolute;top:-75px'> I've searched around and found the .removeAttr() method but I can't see how to add it, or even remote parts of it (like the top:-75px only). Thanks, 回答1:

问题 This is based on my full question. I decided to take it in parts and see if I still can't get any help. What are all the options we've got for client-side frameworks? I've heard mostly about prototype and jquery , but I know there are way too many options out there beyond those two, and I don't know if they handle async download. From all of them which one is the fastest, both on the DHTML (interface) and the AJAX (download)? What are the advantages it has over the others? 回答1: What is it

问题 Is it possible to rotate a Div in cyclic rotation using javascript. I have four DIVs in an HTML page. I need to rotate those DIVs in a cyclic rotation. If it's possible tell me now. It is urgent. 回答1: It's actually not hard: function moveDiv(t,mdiv) { t = t + 0.05; // "time" var r = 10, //radius of circle xcenter = 400, //x location of circles centre on screen ycenter = 400, //y location of circles centre on screen x = Math.floor(xcenter + (r * Math.cos(t))), //circles parametric function y =

问题 I was wondering if there is a way to make a radio button select another radio buttons data. For example, a "select all" radio button, would select another radio button. Or In the event of a survey where a question could be rated from 0 to 5, when "select all as 0" is selected, all the following radio buttons are selected at "0". I feel like there is an easy way of doing this, but I have no Idea what it would be (possibly javascript?) Thanks! 回答1: HTML <button type='button' onclick='selectAs0(

问题 I have a list of elements that need to have a corresponding pop up for each element. This is not a pop up where the background is blacked. This is more like a javascript alert although I need to create my own styled button within the pop up with our own bespoke event assigned to it. I need each pop to position itself appropriately next to the relevant item within the UI. Whats the best way to do this? Are there any examples please? I only want the pop up to show when the visitor triggers an
