get(node,name)

Defined by dojo/dom-attr

Gets an attribute on an HTML element.

Handles normalized getting of attributes on DOM Nodes.

Parameter	Type	Description
node	DOMNode \| String	id or reference to the element to get the attribute on
name	String	the name of the attribute to get.

Returns:any | undefined | null

the value of the requested attribute or null if that attribute does not have a specified or default value;

Examples

Example 1

// get the current value of the "foo" attribute on a node
require(["dojo/dom-attr", "dojo/dom"], function(domAttr, dom){
    domAttr.get(dom.byId("nodeId"), "foo");
    // or we can just pass the id:
    domAttr.get("nodeId", "foo");
});

getNodeProp(node,name)

Defined by dojo/dom-attr

Returns an effective value of a property or an attribute.

Parameter	Type	Description
node	DOMNode \| String	id or reference to the element to remove the attribute from
name	String	the name of the attribute

Returns:any

the value of the attribute

has(node,name)

Defined by dojo/dom-attr

Returns true if the requested attribute is specified on the given element, and false otherwise.

Parameter	Type	Description
node	DOMNode \| String	id or reference to the element to check
name	String	the name of the attribute

Returns:Boolean | contentWindow.document isn't accessible within IE7/8

true if the requested attribute is specified on the given element, and false otherwise

remove(node,name)

Defined by dojo/dom-attr

Removes an attribute from an HTML element.

Parameter	Type	Description
node	DOMNode \| String	id or reference to the element to remove the attribute from
name	String	the name of the attribute to remove

set(node,name,value)

Defined by dojo/dom-attr

Sets an attribute on an HTML element.

Handles normalized setting of attributes on DOM Nodes.

When passing functions as values, note that they will not be directly assigned to slots on the node, but rather the default behavior will be removed and the new behavior will be added using dojo.connect(), meaning that event handler properties will be normalized and that some caveats with regards to non-standard behaviors for onsubmit apply. Namely that you should cancel form submission using dojo.stopEvent() on the passed event object instead of returning a boolean value from the handler itself.

Parameter	Type	Description
node	DOMNode \| String	id or reference to the element to set the attribute on
name	String \| Object	the name of the attribute to set, or a hash of key-value pairs to set.
value	String	Optional the value to set for the attribute, if the name is a string.

Returns:any | undefined

the DOM node

Examples

Example 1

// use attr() to set the tab index
require(["dojo/dom-attr"], function(domAttr){
    domAttr.set("nodeId", "tabIndex", 3);
});

Example 2

Set multiple values at once, including event handlers:

require(["dojo/dom-attr"],
function(domAttr){
    domAttr.set("formId", {
        "foo": "bar",
        "tabIndex": -1,
        "method": "POST"
    }
});
