[DOUBT] How to use setTimeout correctly
Hi team, i was trying to cache 2 objects, but they came from a HTTP request, and took some time to download it. I was unable to use the function setTimeout while calling this function: kimchi.getPCIDeviceCompanions(kimchi.hostPCIs[i].name, setTimeout(function(result) { kimchi.deviceCompanions[kimchi.hostPCIs[i].name] = result; },5000)); } The function kimchi.getPCIDeviceCompanions usually takes 2s to finish. -- Ramon Nunes Medeiros Kimchi Developer Linux Technology Center Brazil IBM Systems & Technology Group Phone : +55 19 2132 7878 ramonn@br.ibm.com
The function "kimchi.getPCIDeviceCompanions" (and most other Kimchi JavaScript functions, actually) receives a callback function which receives a result parameter. That function should be executed when the result is ready. In your case, your parameter function doesn't match this requirement (i.e. you're passing a function which receives a function which receives a parameter). You need to pass parameters exactly as they're expected by the main function. Also, why are you using setTimeout at all?

Hi Cristian, nice to see you here :) The function getPCIDeviceCompanions tooks almost two second for each interation. As this function being called each time that the Edit button is accessed, i want to cache the values on kimchi.main() to save time. On systems that has too much pci devices, a popup from the browser asks for quit the page by unresponsible script. On 07/14/2015 09:14 AM, Crístian Viana wrote:

But I still don't understand how the function setTimeout can help you with that. Adding a timeout probably won't solve your problem, it won't cache anything, it will just delay the page unresponsiveness. On Tue, Jul 14, 2015 at 2:57 PM Ramon Medeiros <ramonn@linux.vnet.ibm.com> wrote:

Hi Cristian, I was trying to do this: 1) Cache all deviceCompanions in a object, that the key will be the hostPCI 2) Query this information when the user enter in guest edit, instead of download everytime the user enter on this page So, why i am asking about setTimeout? I tried to do the operations above and hit an error: The guest_edit page was unable to get the deviceCompanions because they were not downloaded, so, i would like to put an timeout (or other function) to make the function waits for this download, and then, continue to load kimchi.

Hi Ramon, You can check in code how we cache the capabilities values. We do exactly what you want to do for the PCI devices. In ui/js/src/kimchi.host.js you can see the code below: var setupUI = function() { if (kimchi.capabilities == undefined) { setTimeout(setupUI, 2000); return; } ... } Hope it helps you.
