You wish to disable a button depending on a checkbox state.
Use the ng-disabled
directive and bind its condition to the checkbox state.
<body ng-app>
<label><input type="checkbox" ng-model="checked"/>Toggle Button</label>
<button ng-disabled="checked">Press me</button>
</body>
The ng-disabled
directive is a direct translation from the disabled HTML attribute, without you needing to worry about browser incompatibilities. It is bound to the checked
model using an attribute value as is the checkbox using the ng-model
directive. In fact the checked
attribute value is again an Angular expression. You could for example invert the logic and use !checked
instead.
This is just one example of a directive shipped with Angular. There are many others like for example ng-hide
, ng-checked
or ng-mouseenter
and I encourage you go through the API Reference and explore all the directives Angular has to offer.
In the next recipes we will focus on implementing directives.
