jquery template - jumate de MVC

Nu odata am scris ceva asemanator cu aceste cond in jQuery:

var sablon = "<b> ${nume} </b>";
Problema la acest template este modul in care se poate manipula . In cazul in care dorim sa facem o modificare, suntem nevoiti sa cautam in cod unde avem definit template-ul si sa facem modificari pe el. In cazul in care un nou dezvoltator trebuie sa faca modificari, el o sa fie nevoit sa cauta in cod.

O solutie este sa folosim un template pentru acest lucru. Primul pas este sa definim template-ul in forma urmatoare:

<script id="numeTemplate" type="text/html">
<b> ${nume} </b>
</script>
Prin acest mod, o sa ne putem referi template-ul nostru in orice loc din cod pe baza unui ID, totodata o sa fie foarte usor de grupat toate template-urile.

Urmatorul pas este sa referim pe langa libraria de jquery si libraria pentru template-uri. Numele ei este: jquery.tmpl.js.

Template-ul pe care l-am definit mai sus trebuie putin modificat, forma sa trebuie sa fie:

<script id="numeTemplate" type="text/html">
<b> ${nume} </b>
</script>
JSON va scoate automat valoarea pentru nume prin ${}. Putem sa avem orice fel de conditii logice, in exemplul dat mai sus, avem un IF care afiseaza imagini diferite pentru barbati si femei. Prin acest mecanism putem sa cream template-uri complexe, in care logica care defineste modul in care se face randarea la anumite elemente din template sa fie in interiorul la template.
Datele pentru care facem randarea sunt:
var persoane = [
{ Nume = "Stefan", IsMan = 1},
{ Nume = "Oana", IsMan = 0},
{ Nume = "Mihai", IsMan = 1}
];
Pentru a putea folosi template-ul definit, putem sa folosim functiile
  • tmpl([data],[options])
  • $.tmpl(template,[data,[options])
Pentru exemplul dat mai sus ar trebuii sa scriem:
$("numeTemplate").tmpl(persoane).appendTo("#listaPersoaneDiv")
Unde listaPersoaneDiv reprezinta id la divul care afiseaza template-ul.
Si gata, in acest moment avem un template pe care il putem folosi in orice locatie. Putem sa privim totul ca o jumatate din MVC, doar partea de Model-View.

Windows Docker Containers can make WIN32 API calls, use COM and ASP.NET WebForms

After the last post , I received two interesting questions related to Docker and Windows. People were interested if we do Win32 API calls from a Docker container and if there is support for COM. WIN32 Support To test calls to WIN32 API, let’s try to populate SYSTEM_INFO class. [StructLayout(LayoutKind.Sequential)] public struct SYSTEM_INFO { public uint dwOemId; public uint dwPageSize; public uint lpMinimumApplicationAddress; public uint lpMaximumApplicationAddress; public uint dwActiveProcessorMask; public uint dwNumberOfProcessors; public uint dwProcessorType; public uint dwAllocationGranularity; public uint dwProcessorLevel; public uint dwProcessorRevision; } ...

Navigating Cloud Strategy after Azure Central US Region Outage

 Looking back, July 19, 2024, was challenging for customers using Microsoft Azure or Windows machines. Two major outages affected customers using CrowdStrike Falcon or Microsoft Azure computation resources in the Central US. These two outages affected many people and put many businesses on pause for a few hours or even days. The overlap of these two issues was a nightmare for travellers. In addition to blue screens in the airport terminals, they could not get additional information from the airport website, airline personnel, or the support line because they were affected by the outage in the Central US region or the CrowdStrike outage.   But what happened in reality? A faulty CrowdStrike update affected Windows computers globally, from airports and healthcare to small businesses, affecting over 8.5m computers. Even if the Falson Sensor software defect was identified and a fix deployed shortly after, the recovery took longer. In parallel with CrowdStrike, Microsoft provided a too
