Dojo disable all input fields in div container - input

Question

Is there any way to disable all input fields in an div container with dojo?
Something like:
dijit.byId('main').disable -> Input

Answer 1

That's how I do it:
dojo.query("input, button, textarea, select", container).attr("disabled", true);
This one-liner disables all form elements in the given container.

Answer 2

Sure there is. Open up this form test page for example, launch FireBug and execute in the console:
var container = dojo.query('div')[13];
console.log(container);
dojo.query('input', container).forEach(
function(inputElem){
console.log(inputElem);
inputElem.disabled = 'disabled';
}
)
Notes:
On that test page form elements are actually dijit form widgets, but in this sample I'm treating them as if they were normal input tags
The second dojo.query selects all input elements within the container element. If the container had some unique id, you could simplify the sample by having only one dojo.query: dojo.query('#containerId input').forEach( ...
forEach loops through all found input elements and applies the given function on them.
Update: There's also a shortcut for setting an attribute value using NodeList's attr function instead of forEach. attr takes first the attribute name and then the value or an object with name/value pairs:
var container = dojo.query('div')[13];
dojo.query('input', container).attr('disabled', 'disabled');

Answer 3

Something else to keep in mind is the difference between A Dijit and a regular DomNode. If you want all Dijit's within a DomNode, you can convert them from Nodes -> Dijit refs with query no problem:
// find all widget-dom-nodes in a div, convert them to dijit reference:
var widgets = dojo.query("[widgetId]", someDiv).map(dijit.byNode);
// now iterate over that array making each disabled in dijit-land:
dojo.forEach(widgets, function(w){ w.attr("disabled", "disabled"); }
It really just depends on if your inputs are regular Dom input tags or have been converted into the rich Dijit templates (which all do have a regular input within them, just controlled by the widget reference instead)

Answer 4

I would do it like this:
var widgets;
require(["dijit/registry", "dojo/dom"], function(registry, dom){
widgets = registry.findWidgets(dom.byId(domId));
});
require(["dojo/_base/array"], function(array){
array.forEach(widgets, function(widget, index) {
widget.set("disabled", true);
});
});
Method findWidgets is essential to get all widgets underneath a specific DOM.
