Prevent double curly brace notation from displaying momentarily before angular.js compiles/interpolates document – Dev

The best answers to the question “Prevent double curly brace notation from displaying momentarily before angular.js compiles/interpolates document” in the category Dev.

QUESTION:

It seems to be primarily an issue in IE when there is a number of images/scripts to load, there can be a good amount of time where the literal {{stringExpression}} in the markup are displayed, then disappear once angular is done with it’s compilation/interpolation of the document.

Is there a common reason why this would happen which would indicate I’m doing something generally wrong, or is there a known way to prevent this?

ANSWER:

Also, you can use <span ng-bind="hello"></span> instead of {{hello}}.

ANSWER:

I think that you are looking for the ngCloak directive: https://docs.angularjs.org/api/ng/directive/ngCloak

From the documentation:

The ngCloak directive is used to prevent the Angular html template
from being briefly displayed by the browser in its raw (uncompiled)
form while your application is loading. Use this directive to avoid
the undesirable flicker effect caused by the html template display.

The directive can be applied to the <body> element, but the preferred usage is to apply multiple ngCloak
directives to small portions of the page to permit progressive rendering of the browser view

ANSWER:

Just add the cloaking CSS to the head of the page or to one of your CSS files:

[ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak, .ng-hide {
    display: none !important;
}

Then you can use the ngCloak directive according to normal Angular practice, and it will work even before Angular itself is loaded.

This is exactly what Angular does: the code at the end of angular.js adds the above CSS rules to the head of the page.

ANSWER:

To improve the effectiveness of class=”ng-cloak” approach when scripts are loaded last, make sure the following css is loaded in the head of the document:

.ng-cloak { display:none; }
