Trying to use a directive with an ng-show statement in it. Basically it checks against the value of a string which is the status_p1 property in my 'names' jsonarray:
ng-show="name.status_p1==working"
The directive is defined as this:
app.directive('radioButton',function(){
return {
restrict: 'E',
replace: 'true',
template: '<table border="2px">' +
'<tr><td>{{name.name}}</td><td>Working</td><td><img src="http://www.iconshock.com/img_jpg/REALVISTA/general/jpg/256/cross_icon.jpg" alt="img1" id="imgworking" ng-show="name.status_p1!=working"><img src="http://png-1.findicons.com/files/icons/2198/dark_glass/128/camera_test.png" alt="img2" ng-show="name.status_p1==working"></td></tr>' +
'</table>'
};
})
The controller+ namesarray in my main page looks like this:
app.controller('MainCtrl', function($scope) {
$scope.names = [
{
name: 'couple 1',
status_p1: 'working',
status_p2: 'retired'
}
]
});
And finally the main page:
<body ng-controller="MainCtrl">
<div ng-repeat="name in names">
<radio-button></radio-button>
</div>
</body>
Currently is displays a cross where it should be displaying a check/tick. I was expecting the condition to evaluate to TRUE because the status_p1 property equals 'working'. How can I modify this ng-showstatement to make the string comparison working? plunkr link:http://plnkr.co/edit/3VdsbsSHpkNJFVnvkmOW?p=preview
The expression
ng-show="name.status_p1==working"
compares name.status_p1 with a working property on the current scope, which is not defined in your case. What you need is to compare it with the literal string 'working'.
ng-show="name.status_p1=='working'";
Modified Plunkr
In my case, I had this:
ng-show ="authenticated == {{it.logged_in_view}} || {{it.logged_in_view == 'neutral'}}"
and had to change it to this:
ng-show ='authenticated == {{it.logged_in_view}} || {{it.logged_in_view == "neutral"}}'
I enclosed the attribute string in single quotes and the string to be compared in double quotes.
