I get the data from database randomly for my page. And I would like to add a <a> tag to link to the same page for getting another random data. However, since it does nothing if the target page is the same as the current page.
Is any better way to get the new data?
Have a look at this issue: https://github.com/EventedMind/iron-router/pull/324
Basically iron-router adds events to all your a tags. Also the corresponding bit of code: https://github.com/EventedMind/iron-router/blob/79861385df5d2b667630ec82abe4de3efa3166e3/lib/client/location.js#L48
So you need to pass a selector to IronLocation that does include the a tag that does this:
E.g you could do
IronLocation.configure({
'linkSelector' : 'a[href][data-router="true"]'
});
I'm not sure what you're a tags look like. But you could either make all the ones you want to work by changing all the a tags you want to work with iron router, like above. Or change a specific a tag and exlcude it:
'linkSelector' : 'a:not([ironskip])'
Then use <a href=".." ironskip>..</a> for the route you dont want iron-router to handle.
So this way you can specify what a tags you want iron-router to touch and which ones you dont.

Lets say I want to scrape the Neo4j RefCard found at: https://neo4j.com/docs/cypher-refcard/current/
And I would like to fetch a 'code' example along with its styling. Here's my target. Notice that it has CSS treatment (font, color...):
...so in Neo4j I call the apoc.load.html procedure as shown here, and you can see it's no problem finding the content:
It returns a map with three keys: tagName, attributes, and text.
The text is the issue for me. It's stripped of all styling. I would like for it to let me know more about the styling of the different parts of this text.
The actual HTML in the webpage looks like following image with all of these span class tags: cm-string, cm-node, cm-atom, etc. Note that this was not generated by Neo4j's apoc.load.html procedure. It came straight from my Chrome browser's inspect console.
I don't need the actual fonts and colors, just the tag names.
I can seen in the documentation that there is an optional config map you can supply, but there's no explanation for what can be configured there. It would be lovely if I could configure it to return, say, HTML rather than text.
The library that Neo4j uses for CSS selection here is jsoup.
So I am hoping to not strip the <span> tags, or otherwise, extract their class names for each segment of text.
Could you not generate the HTML yourself from the properties in your object? It looks they are all span tags with 3 different classes depending on whether your using the property name, property value, or property delimiter?
That is probably how they are generating the HTML themselves.
Okay, two years later I revisited this question I posted, and did find a solution. I'll keep it short.
The APOC procedure CALL apoc.load.html is using the scraping library Jsoup, which is not a full-fledged browser. When it visits a page it reads the html sent by the server but ignores any javascript. As a result, if a page uses javascript for inserting content or even just formatting the content, then Jsoup will miss the html that the javascript would have generated had it run.
So I have just tried out the service at prerender.com. It's simple to use. You send it a URL, it takes your url as an argument and fetches that page itself and executes the page's javascript as it does. It returns the final result as static HTML.
So if I just call prerender.com with apoc.load.html then the Jsoup library will simply ask for the html and this time it will get the fully rendered html. :)
You can try the following two queries and see the difference pre-rendering makes. The span tags in this page are rendered only by javascript. So if we call it asking for its span tags without pre-rendering we get nothing returned.
CALL apoc.load.html("https://neo4j.com/docs/cypher-refcard/current/", {target:".listingblock pre:contains(age: 38) span"}) YIELD value
UNWIND value.target AS spantags
RETURN spantags
...but if we call it via the prender.com website, you will get a bunch of span tags and their content.
CALL apoc.load.html("https://service.prerender.cloud/https://neo4j.com/docs/cypher-refcard/current/", {target:".listingblock pre:contains(age: 38) span"}) YIELD value
UNWIND value.target AS spantags
RETURN spantags
I'm using anchor tags helpers, which work fine for the most part. I'd like to clean up a particular URL that is getting generated, My tag looks like this (note that type is more specific than id in this case, not that it matters):
<a asp-controller="SomeController" asp-action="SomeAction" asp-route-id="#Model.ID" asp-route-type="#someType">
I would like to get a URL that looks like this:
http://localhost:1234/SomeController/SomeAction/42/1
But instead I get
http://localhost:1234/SomeController/SomeAction/42?type=1
Is there any way to get the 'additional' parameter(s) in a RESTful format, instead of a GET string? I could always just modify the route or URL in a more conventional manner, but was curious if I could make this work.
I'll answer my own question in the hopes that it benefits someone else. The issue was that I needed to create a custom route, like the below:
routes.MapRoute(
name: "newRoute",
template: "{controller=SomeController}/{action=SomeAction}/{id}/{type}");
Interested in alternative approaches, if there is a better practice.
I've made an Add-on which is a custom field.
The style of the text in the field changes depending on the properties of an issue.
I check which style should the text have in the .java file and I pass the html class in a variable called $indicator to the velocity template:
#if( ${value} )
<span class="$indicator">${value}</span>
#end
It works perfect everywhere but in gadgets. When I add this field to a table showing issues in a dashboard, the html code is correct, but it doesn't find the css resource. This is because gadgets are inside an iframe.
How can I make the iframe have a reference to the stylesheet?
You did not say exactly which gadget you were using, but try adding the following context within your <web-resource> module:
<context>jira.webresources:issue-table</context>
The above should work for at least Assigned to Me, Filter Results, In Progress, Voted, and Watched in JIRA 6.1+.
If that does not work, you might also try:
<context>com.atlassian.jira.gadgets:common-lite</context>
If that general context doesn't work, you can look for which exact contexts are #requireContext'ed by the specific gadget you are trying to use, and then make sure that your web-resource is listed in that context. You can figure this out by looking at the gadget's XML and then searching for the #requireContext. (You can find the gadget XMLs inside $JIRA_DATA/plugins/.osgi-plugins/transformed-plugins/jira-gadgets-plugin-*.jar)
Starting with JIRA 7 the Answer of Scott Dudley is no longer working. #requireContext was replaced with a #requireResource within the Atlassian sources of this gadget.
As it affects our plugin, I created a Improvement Request to make that possible again
I have a dynamic PHP stylesheet, but I can't find a way to send variables to it so I used sessions instead. Figured this kinda sucked, so I'm going to give it another try but could need some help. It's an external stylesheet where a variable has effect through the whole document.
You probably want to use an embedded stylesheet (a <style> block) in the page: it increases the size of the main page, but solves the variable access issue without needing sessions and reduces your number of requests. You can just load your dynamic stylesheet into the main page's view using load->view.
EDIT: Ah, massive amounts of CSS would be one problem. Well, two alternatives are to:
Turn on the $_GET support in your CI install, you COULD pass in a request parameter in the CSS link and then check for the request parameter in the PHP controller or view file that generates the actual CSS. Not visually the tidiest option, but it does work.
Put in a cookie that you check in the controller that gets called for the CSS: you can then check that in the controller or view and do the right thing. Visually much tidier than the request parameter option, but a bit more involved.
I know that I need to add the tracking code snippet at the bottom of all my pages, but is there a central location to do this?
Or do I need to add this tracking code to all of my templates?
I guess that I could wrap the snippet in a user control, or external .js file, and reference it on each page, but is there a global footer somewhere? The site I'm working on has about 30-40 layouts, and adding it to each one would be a pain!
Thanks in advance!
Actually, the role of a Sitecore layout is exactly this; to act as a global file that all individual page templates "derive" from.
Normally you'd stick the analytics code into the master layout, and use Sitecore sublayout/placeholder techniques to construct the various page templates you need. You would not normally need more than perhaps one or two layouts for any device you are serving content to. And I guess for most sites, the only device in use is regular web content delivery.
That being said, what you could do, is have all the layouts inherit their codebase from a common base class (inheriting from Page), and inject the google code centrally from here. Would still require you to go through all layout files however.
I have not tried the module, I think that is codebehind version. I have made this in XSLT, its pretty fast and easy to make. I have footer.xslt where I put the code that simply checks if page you are standing on uses template that I want to index and does not belong to page names that I want to exclude. Then I have an item with a custom template for Google Analytics with following memo fields.
IncludeTemplates -field contains list of templates that I want to include for analytics :
ExcludeItemsNames -field for excluding pages by item name
contains($includeTemplates, concat('|',./#template,'|')) and not(contains($excludeItemNames, concat('|',./#template,'|')))
Remember #key and #template is always in small letters
If you run many domains don't forget to add pageTracker._setDomainName("www.example.com"); in analytics script so you can separate sub-domains etc. if they use same footer.xslt
Normally we consider the actual Google code as content. Within Sitecore we normally have a settings folder, something like /sitecore/content/settings. This exists outside the root of the site. Beneath this have a settings item with a plain multi-line text field, I think the field type is memo or something similar.
Afterwards create an XSLT that renders out the content of this settings item. Something like (assuming the field is called value in the setting item):
<xsl:value-of select="sc:fld('Value','/sitecore/content/settings/footerJavaScript')" />
You may or may not need to set the disable-output-escaping attribute.
Then on the aspx page that your pages use as the template add a control that looks at the xslt rendering:
<sc:XslFile runat="server" Path="/xsl/footerJavaScript" />
The reason that we normally keep the javascript as content is this allows the client to change the analytics code without having to contact us.
