Pure HTML + JavaScript client side templating

- by Dev er dev

I want to have achieve something similar to Java Tiles framework using only client side technologies (no server side includes). I would like to have one page, eg layout.html which will contain layout definition. Content placeholder in that page would be empty #content div tag. I would like to have different content injected on that page based on url. Something like layout.html?content=main or layout.html?content=edit will display page with content replaced with main.html or edit.html. The goal is to avoid duplicating code, even for layout, and to compose pages without server-side templating. What approach would you suggest? EDIT: I don't need a full templating library, just a way to compose a pages, similar for what tiles do.

Retreiving data from MySQL with html/javaScript on one domain and the PHP file on the other

- by Mike

I need to retrieve data from a MySQL database, and have it work one way for all types of servers. For example it should work on a server that runs no server side language, it should also work on LAMP, and IIS. I was thinking about using ajax and xmlhttprequest, but learned of the cross domain limitation. I also tried to just include the PHP in a tag, but it comes back with a syntax error in the HTML code created by the PHP file, even though it looks correct. Does anyone know how to fix either of these issues, or have a different way to go about it?

Spring-Security http-basic auth in addition to other authentication types

- by Keith

I have a pretty standard existing webapp using spring security that requires a database-backed form login for user-specific paths (such as /user/**), and some completely open and public paths (such as /index.html). However, as this webapp is still under development, I'd like to add a http-basic popup across all paths (/**) to add some privacy. Therefore, I'm trying to add a http-basic popup that asks for a universal user/pass combo (ex admin/foo) that would be required to view any path, but then still keep intact all of the other underlying authentication mechanisms. I can't really do anything with the <http> tag, since that will confuse the "keep out the nosy crawlers" authentication with the "user login" authentication, and I'm not seeing any way to associate different paths with different authentication mechanisms. Is there some way to do this with spring security? Alternatively, is there some kind of a dead simple filter that I can apply independently of spring-security's authentication mechanisms?

Selecting MXML siblings with actionscript, like javascript?

- by duder

I'm trying to get the sibling of an mxml tag similar to the way siblings are selected in javascript. Is this possible in Actionscript? For example, when I click the TextArea with id textarea1, I need it to tell me that the sibling has an id of rect1 so I can do further processing to it. <s:Group> <s:TextArea id="textarea1" click="getSibling(event)" /> <s:Rect id="rect1" /> </s:Group>

How to have a dynamic theme color in WPF

- by Ingó Vals

In WPF I have a few resource dictionaries and in them styles for my panels and controls in my app. I'm reusing the same colors again and again. I actually have 5 colors and they give my app a good color-scheme. However if I wan't to change the theme I have to go into the RD's and change each and every color there. I would like to somewhere have the colors set but don't know how or where. I tried to put a color tag in one RD but as soon as I referenced it in the same RD Visual Studio crashed. Also the best solution would be that I could have the color as a dynamic setting in the app itself so users could even change it themselves.

Ruby on Rails: link_to_remote and rel

- by DerNalia

I want a link to remote to have a rel tag, because I want to use facebox with it. I had it working with a regular link to... but I needed the link to remote to handle the event that a user doesn't have javascript enabled. this, currently does't work (except for the non-javascript part ) <%= link_to_remote "Ask a Question", {:url => {:action => :ask_question, :id => @container.id.to_s, :javascript_disabled => false }, :rel => 'facebox'}, :href => url_for( :controller => :view, :action => :ask_question, :id => @container.id.to_s, :javascript_disabled => true) %>

Div, Background Image, and Image Map

- by Coolmoondog

On a web page I'm creating, I have a div with a background image. I overlay some text over the image that I'll be changing frequently, so that's why I'm using a background image and real text instead of an img tag that contains the text. The background image contains some click-able areas, so I need an image map. I think the best way to do this is to have another overlay div with a transparent image, and have an image map for the transparent image that corresponds to the background area click-able areas. Am I on the right track, or is there a better way?

Sending BLOBs in a JSON service,... how?

- by Marten Sytema

Hello I have a webservice (ie. servlet) implemented in Java. It gets some data from a MySQL table, with one column being of type BLOB (an image), and some other columns are just plain text. Normally I would store the file outside the database with a pointer to it in the database, but due to circumstance I now have to use this BLOB column... What is the proper way to send this? How to encode the image in a JSONObject, and how to parse (and RENDER!) it on the otherside ? I want to use JSONP, to avoid having to proxy it through the consumer's webserver. So that the consumer can just put in a tag pointing to the webservice, calling a callback. Any thoughts how to handle images in this situation? Also thoughts on performance etc. are interesting!

Combining regroup with get_foo_display in Django templates

- by shacker

I'm using the regroup template tag to group queryset output on a Choices field. In the model: RESOURCE_TYPES = ( ('tut','External tutorial'), ('read','Additional reading'), ('org','Company or organization'), ) restype = models.CharField('Resource type',max_length=6,choices=RESOURCE_TYPES) in the view: resources = Resource.objects.filter(tutorial=tutorial) in the template: {% regroup resources by restype as resource_list %} {% for type in resource_list %} <h3>{{type.grouper}}</h3> So type.grouper renders as 'tut' or 'org' on the page, rather than the long form. Normally you would use the get_foo_display syntax to get at the value of the choice, rather than the key. But the value doesn't seem to be available after going through regroup. There's no way I can find to use get_foo_display on {{type.grouper}}. It makes sense when you think about it, but what's the workaround? Thanks.

Missing safe control entry

- by Stefan Hennicken

I've got a working hello-world like webpart for my SPS3.0 I can compile, pack and deploy it using VS2008, makecab.exe and stsadm. So I know the theory of deploying sharepoint webparts. My problem: After I inserted an additional .webpart file, an elements.xml and a feature.xml to deploy the .webpart file and get knowledge about adding features to my webpart, the deployed webpart is missing its safe control entry in the web.config. But the dll can be found in the gac and my features are also deployed to the right folders. I didn't change anything in my manifest.xml especially not in it's -tag, because it definitely worked before i added my additional feature files. Can anybody help me? Should i provide you some code snippets? Thanks Stefan

Why element creation requires the document object in DOM?

- by maayank

As noted by others, in Java, with the default W3C DOM libraries, one is required to use the Document object a factory to elements, i.e.: import org.w3c.dom.Document; import org.w3c.dom.Element; Document d; Element e; e = d.createElement("tag"); Why is that necessary? Why conceptually a method can't create an XML element without knowing all of the target document? Why I can't just instantiate using 'new' or something to that effect?

Filtering foreign keys with AJAX in Django admin

- by cnobile

I have most of this figured out already. I have AJAX returning the region/state/province when a country is selected. The correct foreign key is saved to the database, however, when the record is viewed afterwards the selected state is not shown in the select nor are any states for the selected country. I understand why this is happening as, the admin view is not aware of the relation between the state and the country. So here is the question. Is there a hook in the admin view that will allow me to load the correct states for the country and set the selected attribute on the option in the select tag? Or how can I override the admin view for any forms that require the country and region/state/province set? I am using jQuery and Djando-1.1. Thanks

JSF and Ajax4JSF on WebSphere 6.1 --> Problem with Form Submission

- by Shamik

Has anyone setup JSF1.1 with Ajax4JSF on websphere 6.1 ? I followed the instructions as mentioned in the developer guide . The problem that I am facing is that once I use a4j:support on any of my h:inputText item, the form values are not getting set in the backing bean on the submission of the form. I do have <h:messages> tag present just above the form so that all the problems should be reported there but I do not see any error message once I submit the form. But I do see that the values are not getting set. I need to find the solution as early as possible otherwise I probably have to throw the ajax4jsf framework and write javascripts instead :(

So I want to submit the form to a confirmation page where the data is processed and where new data is added like the paypal e-mail and the IPN link that needs to be send to, and only then redirected to paypal. is there php code I can use to submit the form immediatly once the data is processed? or should this be done in the meta tag or something like that?

Weblogic / EjbGen: worker manager configuration.

- by Guillaume

I want to declare a worker manager to perform some work in managed thread. Weblogic documentation tells that we can declare a global worker manager using the admin console or declare it in an ejb-jar.xml config file. I want to use the second option. But my ejb-jar.xml is generated by the ejbgen tool. There is no tag in ejbgen that would allow me to declare a worker manager. So how should I create a local worker manager declaration ?

customising serialisation of java collections using xstream

- by Will Goring

I have an object that needs to be serialised as XML, which contains the following field: List<String> tags = new List<String>(); XStream serialises it just fine (after some aliases) like this: <tags> <string>tagOne</string> <string>tagTwo</string> <string>tagThree</string> <string>tagFour</string> </tags> That's OK as far as it goes, but I'd like to be able to rename the <string> elements to, say, <tag>. I can't see an obvious way to do that from the alias documentation on the XStream site. Am I missing something obvious?
