问题 Is there any way to change the attributes of an element when clicking on another element? For example, consider this approach where I have a link like so: <a href="#100">Click me!</a> And then close to it I have this: <span id="100" class="clickTarget">Important text</span> And then on my css file I have this: .clickTarget:target { color: #4f8dd5; } That means whenever the link is clicked, Important text changes its color. The problem with this approach is that the page is also scrolled even

问题 I'm using a DropDownListFor and provide a default selection of -- Select Make -- which has an empty value. I want to provide the user with a hint of what to do (thus the 'Select Make') but don't want to allow them to actually submit that value. Currently the website allows this to go through. I thought that adding a minimum length of 2 would prevent it but no luck. I'm fairly new to .NET MVC so let me know if I'm doing this in the completely wrong way. The actual POST request body is: Make=

问题 I have a Masonry Grid that is working beautifully. It loads perfectly and readjusts. But I am using a plugin that filters results (Search & Filter plugin for Wordpress) and uses AJAX to do that.

Does anyone know how I can do that? Here is my basic HTML structure. <div id="masonry-container> <div id="search

问题 I try to assign an onclick-event on list bullets, or rather the images replacing them, via JavaScript (or JQuery). I now how to get that work when the list-item is also clickable, but that is not what I need. The list item itself should get a doubleclick-event. Assuming we have that list: <ul id="allUsers" class="userselect"> <li id="group1" class="group">Group 1</li> <li id="user1-1" class="user">User 1.1</li> <li id="user1-2" class="user">User 1.2</li> <li id="group2" class="group">Group 2<

问题 I'm using web app from which i send data to server very frequently. Option for sending data should be disabled if app has no internet connection.

问题 what I'm trying to do is to create a login page which goes in front of the actual webpage. From research online, I found out that I can make the actual webpage blurred before the user login. Below is the coding: html: <div id="login"> <form class="form-signin"> <span id="reauth-email"><h2>Login</h2></span> <input type="email" id="inputEmail" placeholder="Email address"> <input type="password" id="inputPassword" placeholder="Password"> <div id="remember" class="checkbox"> </div> <button class=

问题 I'm developing a jQuery-based pivot table. The goal is not a web app but a desktop-based application (C++). In my idea, data is retrieved by the application from the database, then passed to a html page and then showed through the pivot-table plugin. There is no web server and the web page containing the plugin cannot access to the database. So, how to pass data in an efficient way? I've seen other questions here on SO around this matter, but I think we're in a different scenario. Of course I
