anchor

问题 Given an anchor element (with something like $("a:first") ), how do you get the absolute URL that the anchor points to? 回答1: If you're using jQuery 1.6+, you can use .prop() : $("a:first").prop("href") Prior to 1.6, you can access the href property directly on the DOM element: $("a:first")[0].href; 回答2: to get the URL attached you can do something like... var url = $("a:first").attr('href'); this will give you the URL but doesnt guarantee absolute or relative. To find the absolute URL you can

问题 I'm trying to create an image link with the HTML helper of Laravel 4. But it seems that isn't really working. I have this line of code {{ HTML::link("#", HTML::image("img/logo.png", "Logo") ) }} But that just outputs a strin like this: <img src="http://localhost/worker/public/img/logo" alt="Logo"> How come.?? 回答1: You probably will have to: <a href="#">{{ HTML::image("img/logo.png", "Logo") }}</a> Because, link() uses entities to escape the title: public function link($url, $title = null,

问题 I'm trying to use Bootstrap's Pagination style. The documentation says to create the page list like so: <div class="pagination"> <ul> <li class="disabled"><a href="#">«</a></li> <li class="active"><a href="#">1</a></li> <li><a href="#">2</a></li> <li><a href="#">3</a></li> <li><a href="#">4</a></li> <li><a href="#">»</a></li> </ul> </div> The first two links, the left arrow and the 1, should be disabled. When I incorporate it into my django template though, those two are still usable.

问题 I have some links that are placed in my page dynamically via JSON and have no way to directly edit them. I want to force all links to open in new tabs, ala target="_blank" Thought this would work.. but sadly it isn't. Any ideas? $('a').attr("target","_blank"); Here's a jsFiddle with the dynamic code: http://jsfiddle.net/danielredwood/mrgta/7/ 回答1: You could do this (which lets the users browser decide whether to open a new window or tab) $('a').live('click', function() { window.open($(this)

问题 is it possible to somehow send $_POST[] data via a <a> tag? because it seems to automaticly execute the $_POST[] once the page loads rather than when I press the Anchor tag. edit: so what I'm trying to achieve is something like this: I want an anchor tag which would normaly go to somepage.php?variable=something but instead of using $_GET[] I want to send the variable via $_POST 回答1: You can achieve this using jQuery and a HTML form HTML: <form method="post" name="redirect" class="redirect">

问题 I have a button at the top of the page, and I want to code it to proceed to the next anchor regardless of what it is. Actually I will want to do next / previous buttons to go to next and previous anchors. This button is on a static frame so it should scroll the rest of the page ideally. Any suggestions would be great. Again I won't know what the anchor is, this is more like a chapter navigation using a generic button. Seems like finding next anchor object in the dom and go there should be a

问题 As the single way I found to uninstall a webapp is to go to the about:apps page, I wanted to code the following: <p>To uninstall the webapp, please go to <a href="about:apps">about:apps</a></p> But, on Firefox v21 it does not open any page. Then, I failed also using about:config. <a href="about:config">about:config</a> Therefore I wonder whether it is possible to provide a hypertext link to the about:apps or about:config... What are your advices about this issue? EDIT: document.location does

问题 When a FloatingActionButton is anchored to a CollapsingToolbarLayout, it disappears when you scroll up, reappears when you scroll down after a certain point. I was wondering if you can do that with any type of view. In my app, I'm trying to anchor an ImageView to the CollapsingToolbarLayout but it won't disappear like the FloatingActionButton. Here's the XML code. <android.support.design.widget.AppBarLayout android:id="@+id/bar" android:layout_width="match_parent" android:layout_height="252dp

问题 There is a standard from Adobe that in theory specifies opening PDF documents from a link clicked in a browser in a way to open specific sections (AKA "anchor", "named reference") of PDF document. This functionality should be of great help if one would like to refer to a specific portion of large PDF (such as some standard or specification). However, from what I see now, support for this standard is close to non-existent. For example, these links should open Scala Reference PDF at section 3.2
