Input autofocus attribute
angularjs
Solution
Update: AngularJS now has an `ngFocus` directive that evaluates an expression on focus, but I mention it here for the sake of completeness.
The current version of AngularJS doesn't have a focus directive, but it's in the roadmap. Coincidentally, we were talking about this on the mailing list yesterday, and I came up with this:
angular.module('ng').directive('ngFocus', function($timeout) {
return {
link: function ( scope, element, attrs ) {
scope.$watch( attrs.ngFocus, function ( val ) {
if ( angular.isDefined( val ) && val ) {
$timeout( function () { element[0].focus(); } );
}
}, true);
element.bind('blur', function () {
if ( angular.isDefined( attrs.ngFocusLost ) ) {
scope.$apply( attrs.ngFocusLost );
}
});
}
};
});
Which works off a scope variable as you requested:
<input type="text" ng-focus="isFocused" ng-focus-lost="loseFocus()">

Problem
I have places in my code where I have this: ``` <input data-ng-disabled="SOME_SCOPE_VARIABLE" /> ``` I would like to be able to use it like this too: ``` <input data-ng-autofocus="SOME_SCOPE_VARIABLE" /> ``` Or even better, mimicking how ng-style is done: ``` <input data-ng-attribute="{autofocus: SOME_SCOPE_VARIABLE}" /> ``` Does this exist in the current version of AngularJS? I noticed in the code there's a BOOLEAN_ATTR which gets all the attr's that AngularJS supports. I don't want to modify that in fear of changing versions and forgetting to update.
