Some Javascript attributes

Async attributes

The async attribute indicates whether asynchronous download is allowed.
Basic syntax boolValue = XMLDocument. async; XMLDocument. async = boolValue;
The Boolean value is writable (read/write). If asynchronous download is allowed, the value is True; otherwise, the value is False.
Example

Webjx. Com

XmlDoc. async = "false ";
Alert (xmlDoc. async); webpage tutorial Network

Doctype attribute Webjx. Com

File Type node, including the DTD of the current file. This node is a general file type declaration. For example, the Node object named "EMAIL" will be returned.

DocumentElement attributes

Webpage tutorial Network

As the Root node of the validation XML file.
Basic syntax objdoc1_xmldocument.doc umentElement;
It refers to an object that contains data in a single root file element. This attribute is readable/written. If the file does not contain the root node, null is returned.

Implementation attributes

Webjx. Com

DOM applications can use objects in other implementations. The implementation attribute confirms the DOMimplementation object of the current XML file.
Basic syntax objImplementation = xmlDocument. implementation;
This attribute is read-only and returns an object.
Example

ObjImp = xmlDoc. implementation;
Alert (objImp );

LastChild attribute Webjx. Com

Used to confirm the final child element of the current node.
Basic syntax objLastChild = xmlDocNode. lastChild;
This attribute is read-only and returns an object. If the node does not contain the last child element, null is returned.
Example

 

ObjLastChild = xmlDoc.doc umentElement. lastChild;
Alert (objLastChild );

NextSibling attributes

In the subnode list of the current file node.
Basic syntax objNextSibling = xmlDocNode. nextSibling;
This attribute is read-only and returns an object. If the node does not contain any other related node, null is returned.
Example

Webjx. Com

ObjSibling = xmlDoc.doc umentElement. childNodes. item (1). nextSibling;
Alert (objSibling );

========================================================== ==========

NodeName attribute Webjx. Com

Returns the string representing the current node name.
Basic syntax strNodeName = xmlDocNode. nodeName;
Returns a string. This attribute is read-only and returns the element name, attribute, or object reference.

NodeType attributes

Webjx. Com

Identifies the DOM type of a node.
Basic syntax numNodeType = xmlDocNode. nodeType;
This attribute is read-only and returns a value.

Webpage tutorial Network

Valid values are of the following types:
1-ELEMENT
2-ATTRIBUTE
3-TEXT
4-CDATA
5-ENTITY REFERENCE
6-ENTITY
7-PI (processing instruction)
8-COMMENT
9-DOCUMENT
10-DOCUMENT TYPE
11-DOCUMENT FRAGMENT
12-NOTATION
　
Example: Webjx. Com

NumNodeType = xmlDoc.doc umentElement. nodeType;
Alert (numNodeType );

========================================================== ==========

NodeValue attributes

Used to return text related to a specified node. This is not a data value in an element, but a node-related and unparsed text, just like an attribute or a processing command.
Basic syntax varNodeValue = xmlDocNode. nodeValue;
The returned text represents the type value based on the node's nodeType attribute. (See the nodeType attribute in the appendix .) Because the node type may be one of several data types, the return value is also different. The node types that return null include DOCUMENT, ELEMENT, document type, document fragment, ENTITY, entity reference, and NOTATION. This attribute can be erased.
Example: Webjx. Com

VarNodeValue = xmlDoc.doc umentElement. nodeValue;
Alert (varNodeValue );

Ondataavailable attributes

Webpage tutorial Network

Specifies an event to process the ondataavailable event.
Basic syntax xmlDocNode. ondataavailable = value;
This attribute is write-only. Once the data of the file author is available, the data can be used for operation as soon as possible.
Example

XmlDoc. ondataavailable = alert ("Data is now available .");

Onreadystatechange attribute webpage

Specifies an event to process the onreadystatechange event. This event can identify changes to the readyState attribute.
Basic syntax xmlDocNode. onreadystatechange = value;
This attribute is write-only and allows the file author to specify the call event when the readyState attribute changes.
Example

 

XmlDoc. onreadystatechange = alert ("The readyState property has changed .");

OwnerDocument attribute Webjx. Com

The root node used to return the file, including the current node.
Basic syntax objOwnerDoc = xmlDocument. ownerDocument;
This attribute is read-only and returns an object containing the root node of the file, containing a specific node.
Example: Webjx. Com

ObjOwnerDoc = xmlDoc. childNodes. item (2). ownerDocument;
Alert (objOwnerDoc); Webjx. Com

Returns the parent node of the current node. It can only be applied to nodes with a parent node.
Basic Syntax: objParentNode = xmlDocumentNode. parentNode;
This attribute is read-only and returns the parent node object containing the specified node. If the node does not exist in the file tree, null is returned.
Example: Webjx. Com

ObjParentNode = xmlDoc. childNodes. item (1). parentNode;
Alert (objParentNode); Webjx. Com

========================================================== ==========

ParseError attribute webpage

Return a DOM parsing error object, which describes the final parsing error message.

ReadyState attribute Webjx. Com

The current situation of the XML file.
Basic syntax intState = xmlDocument. readyState;
