If I load a string containing HTML into a UIWebView, and that string contains objects (hyperlinks) that are relative to that string, i.e. , where there is some object with id "something," then the link works - click on it and the web view jumps to the referenced object.
What I want is to get navigation to a different file in my project, in other words as though the path to the different file were a URL.
I have found that if the href IS a URL, such as href="http://www.amazon.com", then the link works.
If I put the name of a file, OR the [NSBundle mainBundle] pathForResource: ] of that name, in the href, then the link does not work.
Is there some way I can generate the equivalent of a URL pointing to an HTML file that is in the project, so that an can link to that HTML file?
I found a solution at this link:
How to use Javascript to communicate with Objective-c code?
Essentially, the solution is to implement the UIWebViewDelegate protocol's shouldStartLoadWithRequest method, and "trap" a particular value of scheme. So my links, instead of saying something like:
<a href="http://someplace.location">
are like:
<a href="mylink://#filename.ext">
By catching attempts to load anything with scheme "mylink," I can use:
[[request URL] fragment]
within shouldStartLoadWithRequest, and get the filename.ext. I then release my previous UIWebView, load in the contents of the specified file, and make that the contents of a new UIWebView. The effect is that the links work with normal appearance, even though they are being implemented with my code. I return NO because I don't want the usual loading to take place. If the scheme is NOT mylink, I can return YES to allow normal operation.
Regrettably, I still have no way to jump TO a fragment within a web view. In linking to a real URL, you can say something like "www.foo.org#page50" and jump straight to wherever an object on the new page has an id of "page50." With my method, I can only go to the top of the page.
This is also not going to give me a "go-back" function unless I record the filenames and implement it myself.

In modern Website usually hidden path.
use this
https://google.com/main
instance of this
https://google.com/main.html
but I want to ask why they chose to hidden the file path.
I know that Initial web was use this file path.
But if they chose to cover up it, I think there was some reason.
Because of they just think it doesn't look good?
Or is there a security issue when using a file root?
in tranditional website.all content on the page is static and write in html file.so we can fetch and show the page directly by browser.
in modern internet,the content we browse is dynamic,for example we browse a news page,the content changed every second,so the server handle our request by some function not handle by a static html file,the function always print out latest news,so it is dynamic,not a unchanged static html file.
I'm trying to create a clone of getpocket.com for learning. On that app, every saved link gets converted into a markdown; and it seems like the it's a filtered content with only the page title and body without headers, footers, etc.
I could get the page's title using puppeteer api thru different means:
using page.title()
or get the page's opengraph "og:title"
But how do i get like the summarized version containing only the main content of the page.
Note that i don't know beforehand the "css class" of the main content since i'm planning on just entering a url in a textbox and scrape that site from there.
I have found what i've needed for this scenario.
I used the Readability.js library for making webpages readable by removing some certain html tags. Here's the library.
This library is what mozilla uses behind the scenes when rendering their reader view
In my custom page type, you can select an uploaded file. That's fine, but in my ascx transformation, i'm having a hard time getting the URL. The field is 'Process'.
Here's what i currently have.
<%# IfEmpty(Eval("Process"),"N/A","<a href=" + Eval("Process") +" target='blank' class='icon download'>Download</a>")%>
When rendered, the html is this:
Download
I'm missing something.
You can use either of the 2 methods below. Both have their downfalls though.
<a href="<%# GetFileUrl("Process", "Something") %>"Link here<a/> this will
Downfall with this is if there is no value in the "Process" field, it will return an invalid URL. So I tend to use something a little better (but not much)
Item to download
This will create a valid URL with some invalid properties to it. Meaning if there is no value in the Process field, it will return 00000000-0000-0000-0000-000000000000. If the NodeAlias field is empty, it will return "download". So again, not 100% fool-proof but it works well in most cases.
Update
Check out this link:
https://devnet.kentico.com/articles/options-for-file-fields-in-structured-data
I think the piece you need in here is in the "CMS.File page type" section:
This is the link to the picture
Check out transformation methods reference
You can use <%#GetImage(Eval("Process"))%>. This will return an Image tag. There are a couple other parameters for sizing if you want to use those.
See the "Transformation reference" link on your Trasnformation editor, it goes to all the available transformation methods you can use.
In it it shows:
This will generate an actual image tag. If however you want a link, it usually is
/getattachment/<%# Eval("TheImage")%>/ImageFileNameCanBeAnythingThough.jpg
example:
/getattachment/1936c69d-a28c-428a-90a7-09154918da0f/Christmas.jpg
I'm trying to render the HTML for a content item to a string from within a controller action. Technically I just want to get the "body" part of it without any header/footer stuff. I want to do this so I can get a content item rendering the way I want once, and then display it as a normal orchard page OR by requesting the HTML for the content item via ajax to display it in a div in a JavaScript app. I don't want to have to manually render everything in the JavaScript as that would be duplicating the layout logic I already did. I want to re-use the bulk of the server side rendering so any changes are reflected in my normal orchard page and my JavaScript page. I've been digging into the code and searching everywhere and have gotten close but not all the way there.
I found these:
How to render shape to string?
Using FindView in Orchard
In my controller I have:
var shape = _contentManager.BuildDisplay(contentItem);
Using either of the two methods above, I can render that shape to an HTML string in my controller. All was golden. I was getting the body of that page and using it in JS. Then, I changed a placement file:
<Place Parts_Common_Body="Content:1" />
was changed to:
<Place Parts_Common_Body="/AsideFirst:1" />
The body moved where I wanted it (AsideFirst) in my normal Orchard page but disappeared from the HTML retrieved using the two methods above.
If I look at shape.Content.Items after the BuildDisplay call, I can see the item for the body is no longer there... why is it not rendering all the zones? Or, I guess a more specific question is why is the BuildDisplay method not building the complete shape? Is there a way I can make this work?
I tried a million different things and eventually got this working. Not sure I totally get it yet, but I think the problem had to do with the fact that I was using shape.Content and I'd moved stuff out of the Content zone. And maybe when I was looking at what the BuildDisplay method was returning I was just not looking at some newly created zone that actually did had the stuff I thought was missing. Clearly I need to learn more about zones and shapes... Anyway, I have a new zone called "MainInfo" now that I created in a placement file. I get a MainInfo property on the main shape returned form BuildDisplay and pass shape.MainInfo to the view rendering code and all seems to be working well now.
I'm trying to create a CSS documentation library in Orchard. I want to save a description, CSS snippet and HTML snippet against each content type. The first view would show the description and CSS and HTML code written out. The second view would show a preview of what the CSS and HTML look like rendered.
cssdocumentation.com/content/item1
cssdocumentation.com/content/item1/live-preview
I've created the content type and the first view. But I'm not sure how to create the second view. I can see if I can create the alternative URL I can use the Url Alternates module to create an overriding .cshtml
To create an alternative URL I've looked at the autoroute module but this only allows you to adapt a single URL (unless I'm missing something?) and I've looked at Alias UI but this forces me to manually create an alternative URL everytime I create a content item.
Is this possible in Orchard without writting too much C#? (I'm a frontend developer so I only dabble in the behind the scenes stuff)
Thanks for any help
Best solution is to do this within your own module. But as a secondary option instead of having a second page, combine this content with your first page and hide it with CSS. When the user clicks a button to navigate to the next step render the CSS/HTML result on the same page. You can do this in many ways, here are a few ideas:
Render the CSS/HTML result out straight away on the same page but hide it. Show it when the user clicks a button
using jQuery to render the result on the client side. More dynamic if you allow editing of the HTML and CSS.
Redirecting the user to the same page with specific url parameters which you can pick up in your alternate to modify the output.
