<can-ajax> is a can.Component for performing XHR requests. You might be thinking that XHR is not something that belongs in markup, and you may be right, but <can-ajax> is an experiment in using the power of can.Component's scoping to allow a greater degree of dynamism within your templates. For example, with <can-ajax> it is trivial to decouple components from the data they use and conditionally display loading indicators:
<can-ajax url="/todos">
{{#if loading}}
<img src="loading.gif"/>
{{else}}
<todo-list todos="data"></todo-list>
{{/if}}
</can-ajax>The easiest way to install <can-ajax> is with Bower:
bower install can-ajaxThe following attributes can be used to control <can-ajax>:
The string url to load, for example /todos.
Optional http method to use for the request. Defaults to GET if none is selected.
Optional query string to include with the request (you can also just provide the query string as part of the #url.
