If x.title is empty then i want to show a message to user current it is displaying messag in both case whether it is empty or have some value
Sorry but you need to be more specific, this is simply not enough to give you a satisfactory answer.
Read this:
If I understood you right I might have an answer for you. If you are having in account that, even tho a request has been fulfilled successfully, the data received is empty, and you want to show the user that it’s no mistake (as in a search with no results) you can try something like this (pseudo-code):
onStart
gotData = false;
getData()
success: gotData = true
In HTML you can then check for something like
ng-show="gotData && x.title.length > 0"
So if the title is empty and you already got the data you can show a “No results” or whatever you like. Does that help?
