Is there a way in a directive to check if an element has a specific attribute before performing a function on it? I couldn't find anything related to this in the jqLite documentation.
For example:
.directive('noReadonly', function() {
return {
link: function($scope, $element, $attr, ctrl) {
$element.on('focus', function() {
if ($element.hasAttribute('readonly'))
$element.removeAttr('readonly');
});
},
}
})
$attr is an object containing attributes that can be manipulated in a normal way:
if($attr.hasOwnProperty("readonly"))
It is important to note that this code snippet checks for the existence of a property. For example, the following input element would trigger a true response:
<input name="test" readonly>
If you also want to verify if the value is truthy, you can enhance the logic as follows:
if($attr.hasOwnProperty("readonly") && $attr.readonly) {}
Keep in mind that attribute values are treated as strings, so $attr.readonly is equal to "true" (as a string) and not true (as a boolean).
if ($attr.disabled) {
...
}
else {
//not present
}
