Referencing the context path from within Javascript?
Hello,
I would like to avoid hard-coding the context path for the *url* variable
below:
* <script type="text/javascript">*
* jQuery(document).ready(function() {*
* jQuery("#accountPostcode").autocomplete({*
* source : function(request, response) {*
* var jqxhr = jQuery.ajax({*
* url : "
http://localhost:8080/bignibou-web/utils/JSonPostcodesWithQueryParam",*
* type: 'GET',*
* data: { term: request.term },*
* dataType : "json"*
* }).fail(function() { *
* console.log("error:");*
* console.log(jqxhr.statusText);*
* }).success(function(data) {*
* response(data);*
* });*
* },*
* minLength : 2*
* });*
* });*
* </script>*
How can I achieve this with T5?
Thanks in advance,
Julien.

Page templates don't handle anything. Pages, components (through events
URLs), request filters (not common) and dispatchers (common). I still
don't know what you're doing unless you post the code.

That's ok, but then you're not using a stack. It would have worked if you
included it as a library. I've never used tapestry5-jquery myself, but I
do think it deserves to be tried at least once. ;)

@Thiago,
I actually wanted to avoid an additional dependency.
I am going to include the autocomplete javascript within the root layout as
a library.
@All
Thanks all for helping me with this issue!! I understand how Tapestry deals
with javascript much better now!! [?]

Julien.

Are you using tapestry5-jquery? It should take care of it. In addition, to
use 'context:...', you should use @Import(library="..."), not stack.

I tried using the "@Import stack=" in order to include the jquery libraries
to no avail.
I get this:
Render queue error in SetupRender[Index:childminderlayout.layout]: No
JavaScriptStack with name 'context:/js/jquery-1.6.2.js'.
Any one has any clue?

You don't. Make it a parameter of a function you'll call through
JavaScriptSupport.addScript().
To include a JS file, use @Import. addScript() is used to add lines of
JavaScript at the bottom of your page, typically to do initialization
stuff. JumpStart has one nice example:

You're right François,
It is an issue with the inclusion order of my files.
I noticed that the files @Import(ed) by my main layout component come after
the files @Import(ed) by the pages that use that layout. It should be the
other way around.
Is there a way to have more control over that?
Julien.

This should work. Perhaps a conflict regading inclusion order of your js file.
At this point you have to debug with firebug to see why
Tapestry.Initializer.bignibou_autocomplete() is not defined.
perhaps extend failed as jquery was already there.

Hi François,
I like your solution as it seems more flexible. I tried to implement it as
follows:
/js/jquery.autocomplete.js:
*jQuery.noConfict();*
*(function($) {*
* $.extend(Tapestry.Initializer, {*
* bignibou_autocomplete : function(specs) {*
* $("#accountPostcode").autocomplete({*
* source : function(request, response) {*
* var jqxhr = $.ajax({*
* url : specs.link,*
* type : "GET",*
* data : {*
* term : request.term*
* },*
* dataType : "json"*
* }).fail(function() {*
* console.log("error:");*
* console.log(jqxhr.statusText);*
* }).success(function(data) {*
* response(data);*
* });*
* },*
* minLength : 2*
* });*
* }*
* });*
*})(jQuery);*
*
*
>From my T5 java page:
*
*
*@Import(library = "context:/js/jquery.autocomplete.js")*
*...*
*
@AfterRender
public void afterRender() {
Link jSonPostcodesWithQueryParamLink =
pageRenderLinkSource.createPageRenderLink(JSonPostcodesWithQueryParam.class);
String link = jSonPostcodesWithQueryParamLink.toAbsoluteURI();
JSONObject specs = new JSONObject();
specs.put("link", link);
javaScriptSupport.addInitializerCall("bignibou_autocomplete", specs);
}
*
I get the following T5 error:
Function Tapestry.Initializer.bignibou_autocomplete() does not exist.
Any idea what I am getting wrong?

J.

Re: Referencing the context path from within Javascript?
Posted by Julien Martin <ba...@gmail.com>.
Thanks Lenny,
Is the dependency to "com.flowlogix.web.services.AssetMinimizer" necessary?
Is there a "pure-T5" way of retrieving the string from the script?
Here is what I came up with borrowing from your code:
*javaScriptSupport.addScript(getString(openStream(jsAutocomplete)), link);*
*
*
*
private String getString(InputStream is) throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = br.readLine()) != null) {
sb.append(line).append("\n");
}
return sb.toString();
}
private InputStream openStream(Asset asset) throws IOException {
return asset.getResource().openStream();
}
*
It is very low-level but does work.

J.

Thanks François,
I have actually. The issue is how to replace a variable within the js file
with the appropriate value. This seems easy enough with an inline script as
above but if the script is located in its own file I don't know how to
achieve the desired effect.
Regards,
Julien.

Hi Julien,
did you try the use of @Import to import your js file as explained
http://tapestry.apache.org/javascript.html?

Hi Thiago!
Using your advice, I managed to generate the link easily. I have also moved
the script to a separate file as advised.
Now what remains unclear to me is that the *addScript* method takes a
String and not a url to my javascript file.
So on the one hand I have my link, on the other my javascript file. I
understand the rationale behind the addScript method: formatting the
content of the js file with one or several variables passed as the second
argument but what I have is js file not a short script as in the
documentation:
javaScriptSupport.addScript(
"$('%s').observe('click', hideMe());",
container.getClientId());
How do I pass my js file to the addScript method or do I use another method?
Regards,
Julien.

So the correct way of generating an URL for a page is to @Inject
PageRenderLinkSource and use one of its methods. They return a Link. Pass
the result of the toAbsoluteURI() method to your JavaScript method by
@Inject'ing JavaScriptSupport and using its addScript() method.
In addition, as you're returning JSON content, instead of return
TextStreamResponse, you can return a JSONObject or a JSONArray.

Thiago,
Yes it is indeed a Tapestry page. Here is the java code for it (there is no
template for this page):

*
*
*import com.bignibou.domain.utils.PostcodeJson;*
*import com.bignibou.service.AccountService;*
*import com.google.gson.Gson;*
*
*
*public class JSonPostcodesWithQueryParam {*

Is JsonPostcodesWithQueryParam a Tapestry page? By the away, avoid using
inline JavaScript (just as you've done in the template you've posted) and
move it to a .js file which you can include automatically using @Import.

Hello Thiago,
Here is the code from the T5 template:
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery("#accountPostcode").autocomplete({
source : function(request, response) {
var jqxhr = jQuery.ajax({
*url : "http://localhost:8080/bignibou-web/utils/JSonPostcodesWithQueryParam
",*
type: "GET",
data: { term: request.term },
dataType : "json"
}).fail(function() {
console.log("error:");
console.log(jqxhr.statusText);
}).success(function(data) {
response(data);
});
},
minLength : 2
});
});
</script>
The bold line is the problematic one. I need to generate dynamically this
part of the url:
*
*
*"http://localhost:8080/bignibou-web/*

Julien.

As a general answer, you can @Inject HttpServletRequest and use its
getContextPath() method. Depending on who handles this URL (a Tapestry
page? a Tapestry page event handler method), the response would be
different.
