In an HTML document I have a large inline SVG object with groups bearing a variety of IDs (or none at all). I want to find all groups other than those whose IDs start with the letter sequences l0pzlo, l1pzloand l2pzlo. The task of finding just those IDs is easy
element.querySelectorAll("[id^=l0pzlo_],[id^=l1pzlo_],[id^=l2pzlo_]")
does the trick. However, I cannot work out how to get only those elements whose IDs DO NOT start with any of the three prefixes given above. I have attempted to use :notin a variety of different ways, e.g.
element.querySelectorAll(:not('[(id^=l0pzlo)]'))";
but nothing seems to be to the liking of the browser. How can I do this?
I think it would be more useful to leave my own answer here rather than just delete the question
element.querySelectorAll('*:not([id^=l0pzlo]):not([id^=l1pzlo]):not([id^=l2pzlo])');
works. Think of it as going about the task of filtering in a non-greedy way. First you get absolutely everything and then progressively filter out what you don't need with a sequence of one or more :nots
Using jqGrid free (version 4.15.6) to show very basic information about invoices (ie: date created, date due, client, total, status). The invoices grid only has a few pertinent columns that are displayed because it is just not needed to show more than that. In reality there are a lot of other invoice-related fields that are not shown. I would like to offer end-users the ability to filter the grid based on a lot of these other parameters that are simply not part of the grid contents.
I know jqGrid offers built-in searching, and you can easily just add hidden columns with all the data, but I feel this is not good for us--invoices contain a lot of data--data that is not necessarily present in just the invoices database table. We want the grid to provide many other filtering options outside of the base invoice data but we do NOT want to use the built-in filter options. Instead, I would like to use a separate HTML table with a bunch of search fields that our server-side code would know how to pull back). When one decides to invoke the external filter, we want the grid to load all invoices matching that combined filter. And if one chooses to navigate using the grid's paging buttons, we want the grid to continue using the original external filtering parameters.
Hope this makes sense. Maybe I am just overthinking this but I am fairly certain the grid is designed to use it's built in filtering/searching tools/dialog and I have not found anyway to override this behavior. Actually I have using an older jqGrid but that involved using jQuery to completely REPLACE the default pager with custom HTML and event handling. I never could figure this out with older jqGrid so I chose to write it myself. But that code is less than optimum and even I know it is subject to much criticism. Having upgraded to 4.15.6, I want to do this the best way and I want to keep it logical and practical.
I have tried using beforeRequest() and onPaging() events to change the 'url' parameter, thinking that if I modified the url, I could change the GET to include all of our custom filtering fields. It seems that does not work as the url NEVER changes from the originally defined value. Console logging does show the events firing but no change to url. On top of that, the grid ALWAYS passes its own page field, _search field, etc. to the server so the server NEVER sees the filter request.
How does one define their own custom filtering coupled with paging loader and still take advantage of the built-in paging events? What am I missing?
**** DELETED CODE THAT WAS ADDED TO QUESTION THAT DID NOT PERTAIN TO ORIGINAL QUESTION ISSUE *********
It's difficult to answer on your question because you didn't posted code fragments, which shows how you use jqGrid and because the total number of data, which could be needed to display in all pages isn't known.
In general there are two main alternatives implementing of custom filtering:
server side filtering
client side filtering
One can additionally use a mix from both filtering. For example, one can load from the server all invoices based on some fixed filters (all invoices of specific user or all invoices of one organization, all invoices of the last month) and then use loadonce: true, forceClientSorting: true options to sort and to filter the returned data on the client side. The user could additionally to filter the subset of data locally using filter toolbar of searching dialog.
The performance of client side is essentially improved last years and loading relatively large JSON data from the server could be done very quickly. Because of that Client-Side-Filtering is strictly recommended. For better understanding the performance of local sorting, filtering and paging I'd recommend you to try the functionality on the demo. You will see that the timing of local filtering of the grid with 5000 rows and 13 columns is better as you can expect mostly from the round trip to the server and processing of server side filtering on some very good organized database. It's the reason why I recommend to consider to use client side sorting (or loadonce: true, forceClientSorting: true options) as far it's possible.
If you need to filter data on the server then you need just send additional parameters to the server on every request. One can do that by including additional parameters in postData. See the old answer for additional details. Alternatively one can use serializeGridData to extend/modify the data, which will be set to the server.
After the data are loaded from the server, it could be sorted and filtered locally before the first page of data will be displayed in the grid. To force local filtering one need just add forceClientSorting: true additionally to well known loadonce: true parameter. It force applying local logic on the data returned from the server. Thus one can use postData.filters, search: true to force additional local filtering and sortname and sortorder parameter to force local sorting.
One more important remark about using hidden columns. Every hidden column will force creating DOM elements, which represent unneeded <td> elements. The more DOM elements you place on the page the more slow will be the page. If local data will be used (or if loadonce: true be used) then jqGrid hold data associated with every row twice: once as JavaScript object and once as cells in the grid (<td> elements). Free jqGrid allows to use "additional properties" instead of hidden columns. In the case no data will be placed in DOM of the grid, but the data will be hold in JavaScript objects and one able to sort or filter by additional properties in the same way like with other columns. In the simplest way one can remove all hidden columns and to add additionalProperties parameter, which should be array of strings with the name of additional properties. Instead of strings elements of additionalProperties could be objects of the same structures like colModel. For example, additionalProperties: [{ name: "taskId", sorttype: "integer"}, "isFinal"]. See the demo as an example. The input data of the grid can be seen here. Another demo shows that searching dialog contains additional properties additionally to jqGrid column. The commented part columns of searching shows more advanced way to specify the list and the order of columns and additional properties displayed in searching dialog.
Forgive my answering like this but this question started out on one subject related to filtering and paging but with using an external filtering source. Oleg actually has several demos over many threads that I was able to use to accomplish the custom filtering and maintain default built-in paging. So his answer will be the accepted answer for the original question topic.
But in the solution of original, I encountered another issue with loading the grid initially. I wanted to have the grid load with default filtering values should no other filter already be in place. That really should have been a different question because it really did not affect the first.
I found yet another Oleg reply on a completely different question:
jqGrid - how to set grid to NOT load any data initially?.
Oleg answered that question and that answer solved our second need to load one way, then allow another way.
So, on initial load, we look for the filter params server-side. None given? We pull records using default filtering. Params present? We use initial provided params. The difference with initial loading we do not AJAX exit. We instead json_encode the data and place it in the grid definition as follows:
$('#grd_invoices').jqGrid(
...
url: '{$modulelink}&sm=130',
data: {$json_encoded_griddata},
datatype: 'local',
...
});
Since the datatype is set to 'local', the grid does NOT go to server initially, so the data parameter is used by the grid. Once we are ready to filter, we use Oleg's solution from yet another answer on yet another question to dynamically apply the filter as follows:
var myfilter = { groupOp: 'AND', rules: []};
myfilter.rules.push({field:'fuserid',op:'eq',data:$('#fuserid').val()});
myfilter.rules.push({field:'finvoicenum',op:'eq',data:$('#finvoicenum').val()});
myfilter.rules.push({field:'fdatefield',op:'eq',data:$('#fdatefield').val()});
myfilter.rules.push({field:'fsdate',op:'eq',data:$('#fsdate').val()});
myfilter.rules.push({field:'fedate',op:'eq',data:$('#fedate').val()});
myfilter.rules.push({field:'fwithin',op:'eq',data:$('#fwithin').val()});
myfilter.rules.push({field:'fnotes',op:'eq',data:$('#fnotes').val()});
myfilter.rules.push({field:'fdescription',op:'eq',data:$('#fdescription').val()});
myfilter.rules.push({field:'fpaymentmethod',op:'eq',data:$('#fpaymentmethod').val()});
myfilter.rules.push({field:'fstatus',op:'eq',data:$('#fstatus').val()});
myfilter.rules.push({field:'ftotalfrom',op:'eq',data:$('#ftotalfrom').val()});
myfilter.rules.push({field:'ftotal',op:'eq',data:$('#ftotal').val()});
myfilter.rules.push({field:'fmake',op:'eq',data:$('#fmake').val()});
myfilter.rules.push({field:'fmodel',op:'eq',data:$('#fmodel').val()});
myfilter.rules.push({field:'fserial',op:'eq',data:$('#fserial').val()});
myfilter.rules.push({field:'fitemid',op:'eq',data:$('#fitemid').val()});
myfilter.rules.push({field:'ftaxid',op:'eq',data:$('#ftaxid').val()});
myfilter.rules.push({field:'fsalesrepid',op:'eq',data:$('#fsalesrepid').val()});
var grid = $('#grd_invoices');
grid[0].p.search = myfilter.rules.length>0;
$.extend(grid[0].p.postData,{filters:JSON.stringify(myfilter)});
$('#grd_invoices').jqGrid('setGridParam',{datatype:'json'}).trigger('reloadGrid',[{page:1}]);
This allows us to have the grid show initial data loaded locally, and then subsequent filtering changes the grid datatype to 'json', which forces the grid to go to server with new filter params where it loads the more specific filtering.
Credit goes to Oleg because I used many of his posts from many questions to reach the end result. Thank you #Oleg!
I'm using a virtual document structure generated by a script to create a document from EA, and I'm trying to use the same template fragment several times with different elements and different headings.
For example, I have an element which describes the input data to one program, and the output data to another program, so I can't really store the information in the element I'm documenting.
Where it is the input, I want one heading (and similar references within the template), and where it is output I want different values for the headings.
I've tried using the ReportTitle tagged value in the individual <model document> element, but this appears to be ignored and only the <report package> value is used throughout (which makes me wonder why they are there in the first place).
While I could create multiple templates all referring to the same fragment and hard-code the different headings, but that is messy, and as I already have fragments within fragments so it could result in a lot of almost identical templates and fragments. Variables that I can set for each <model document> would be much preferable.
Has anyone got a better approach than this? Thanks!
I don't think there's an easy solution.
If there is a way to determine based on the element, package, or diagram ID whether you should use one title or the other then you could use a script or SQL fragment to return the correct title.
If that is not the case I guess the only possibility is to hardcode the different titles in your templates.
In order to avoid too much duplication you could create a template with only the title and use that on a model document. Since you are generating the modeldocuments by a script anyway that doesn't cost any user time.
Is there a way to dynamically create tables in wiki?
Usecase : I'm trying to mimic similar to soap sonar in fitnesse. SOAP SOANR 1. Once we import the wsdl, soap sonar generates inputs for operations in wsdl. 2. Choose a operation, Enter input and then execute the operation. 3. In case of arrays, we can select size of array and enter values in respective array.
Fitnesse 1. I'm able to achieve point 1 using soapui jars. 2. This i'm able to achieve using xmlhttptest fixture
I'm stuck in 3rd point. Is there a way i can do this in fitnesse? (My idea is from point 1, i can get sample input for each operation, from which i will get to know that there are arrays/complex types present in input.xml but how do we represent this in wiki dynamically?
Thanks in advance
What I've done in the past is use ListFixture (and MapFixture) to dynamically fill a List (and Map/Hashes for each element's properties) and then use these as input values to a XmlHttpTest's feature to create the body to be sent using a FreeMarker template (which allows iteration over a list, which I use to create elements in the array based on the list).
But this gets quite complex quickly. Is that level of flexibility truly required? I found that quite often hard coding the number of elements in arrays/lists in the wiki is simpler to do and makes the test far easier to understand/maintain.
I most cases I prefer to create a script (or scenario) with the right number of elements for the test case(s) in with the request in the wiki page. The use of scenarios allows me to test with different values (but the same number of elements). Another element count gets its own script/scenario.
Being able to dynamically change the number of elements is only worthwhile if you need to test for many different counts, otherwise the added complexity of dynamically creating the body is just not worth it.
I need to build a custom id validator that will apply to a single collection, whose id will always be pre-defined (won't need a generator).
In the docs about id generators, it's written:
Currently the configuration of the custom generator applies to every resources (buckets, groups, collections, records). This tiny limitation can easily be fixed, don’t hesitate to get in touch with us!
But there is nothing documented about id validation.
So, how do I:
Implement an id validator, that
Will apply to one collection only?
By default cliquet uses a generator which accepts the following regular expression r'^[a-zA-Z0-9][a-zA-Z0-9_-]*$' (All letters and numbers + underscore and "-").
Before you chose to have a different ID validation mechanism, ensure you really need to.
Now, if that's not enough, you would need to select the proper validator depending on some configuration or already existing values, but this is not implemented in cliquet / kinto.
https://github.com/mozilla-services/cliquet/blob/master/cliquet/resource/init.py#L147 is probably a good place to look at / start with.
