AlloyUI selector for multiple ids

Question

I want to call a function on blur of two elements, but I can only get it to work for a single element.

I used the A.one() method to select the elements.

Here is my code:

AUI().use('aui-base','aui-io-request', function(A){
    A.one('#<portlet:namespace/>hospitalName',
        '#<portlet:namespace/>date').on('blur',
        function(){

    });
});

Answer 1

To select multiple elements by id in AlloyUI (and YUI), use the Node.all method and a CSS selector like #id1, #id2, #id3.

For your example, the solution would look something like this:

A.all('#<portlet:namespace/>hospitalName, #<portlet:namespace/>date').on('blur',
    function(event){
        // event.target is the blurred element.
        /* your code here... */
    }
);

See this runnable example for more details:

YUI().use('node', function(A) {

  A.all('#hospitalName, #date').on('blur', function(event) {
    var input = event.target;
    document.getElementById('output').innerHTML = input.get('id') + ' blurred';
  });

});
