javascript - Optimize AngularJS ngHide attribute -

- 

  & lt; span ng-hide = "(getStatusIcon (निष्क्रिय.currentStatus.code) .statusDesc) == ' समाप्त हो गई '() (getStatusIcon (inactive.currentStatus.code) .statusDesc) ==' अस्वीकृत '|| (getStatusIcon (inactive.currentStatus.code) .statusDesc) ==' मना कर दिया '"& gt; पीओ # [[असक्रिय.poNumber]] & lt; / span & gt;

मैं कोड को अनुकूलित करना चाहूंगा यदि GetStatusIcon (inactive.currentStatus.code) .statusDesc है (समाप्त हो गया है, अस्वीकार कर दिया गया है) हम स्पैन टैग छुपा रहे हैं अभी हम फ़ंक्शन को 3 बार बुला रहे हैं GetStatusIcon (inactive.currentStatus.code) को चेक करने का एक तरीका है। StatusDesc (समाप्त हो गया, अस्वीकार कर दिया गया) फ़ंक्शन केवल एक बार कॉल कर रहा है।

आप एनजी-इनइट का इस्तेमाल केवल फ़ंक्शन को कॉल करने के लिए कर सकते हैं: 

  & lt; span ng-init = "statusDesc = getStatusIcon (inactive.currentStatus.code) .statusDesc" ng-hide = "(statusDesc) == 'समय सीमा समाप्त' || (statusDesc) == ' अस्वीकृत '|| (स्थितिडिस्क) ==' अस्वीकृत '"& gt; पीओ # [[असक्रिय.poNumber]] & lt; / span & gt;

और फिर आपको नियंत्रक में अपने संकुचन रखना चाहिए। 

  & lt; span ng-init = "statusDesc = getStatusIcon (inactive.currentStatus.code) ) .statusDesc "ng-hide =" हैInvalidStatusDesc (statusDesc) "& gt; पीओ # {{असक्रिय.poNumber}} & lt; / span & gt; फ़ंक्शन mainCtrl ($ गुंजाइश) {$ scope.isInvalidStatusDesc = function (statusDesc) {switch (statusDesc) {case 'expired': मामले 'अस्वीकृत': case 'Refused': return true; डिफ़ॉल्ट: वापसी झूठी; }}; }

I am trying to use the ASP.NET signal for the first time - here's what I did: created a new web Has been added to the project and the following signal R packages: I have created the following category: [Hub-name ("chat")] Public class ChatHub: Hub {Public Zero Halo () {Clients.All.hello ( ); }} and the following startup configuration: public partial class startup {public zero configuration (IAppBuilder app) {configure (app); App.MapSignalR (); }} However, whenever I navigate localhost: (port) / api / signalr / chat I get the following error: Protocol error: Unknown transport.

svn - Cannot merge back into trunk, must be ancestrally related. But they *are* related as far as I understand -

So I'm trying to merge back into my trunk, but I'm getting errors saying that I Because they are not related to the ancestors but I am not clear why this is why. Here is the graph generated by TartiSesWN The trunk is at the bottom left (14698) Currently, I am starting with the merger in the trunk (15 9 7 9) from the top right, this is an example which claims that it is not related to the ancestors, some disparities in it That is what a coworker presented, and I'm not sure it could be the reason for this. If you notice, in the right middle, the branch with modification number 15406 actually divides a tag. It seems incredibly wrong to me, but I'm not sure. A few months ago the coworker did this (he does not work here anymore). However, they should be related to all ancestors because they come from all trunk, right? If this is true, then why am I getting this error? Will a tag be divided? The head of the trunk is 16063 (as per the figure), 14698 merge-s...
