Document. body. onmouseout = "func ()" // triggered when the mouse pointer is removed from the object
-----------------------
Location-location sub-Object
Part after document. location. hash // #
Document. location. host // domain name + port number // it seems that the returned host name is localhost, and no port number is returned
Document. location. hostname // Domain Name
Document. location. href // complete URL
Document. location. pathname // directory
Document. location. port // port number
Document. location. protocol // network protocol (http :)
Document. location. search //? Part after
Using eny. location. reload () // refresh the webpage
Document. location. reload (URL) // open a new webpage
Document. location. assign (URL) // open a new webpage

-----------------------
Selection-selection Sub-Object
Document. selection
For example:
Select some text here.
<ｓｃｒｉｐｔ type="text/javaｓｃｒｉｐｔ" language="javaｓｃｒｉｐｔ">
CreateRange method of selection
Document. selection. createRange () returns a TextRange object based on the current text selection, or returns a ControlRange object based on the control selection.
ExecCommand can be used in HTML editors, such as bold text, italic text, copying, pasting, and hyperlink creation.
These seem to be implemented only in IE ..
-----------------------
Images set (images in the page)
A) reference through a set
Document. images // the img tag on the corresponding page
Document. images. length // Number of img labels on the page
Document. images [0] // 1st img tags
Document. images [I] // I-1 img tag
B) direct reference through the name attribute
Img name = "oImage"
Document. images. oImage // document. images. name attribute
C) reference the image's src attribute
Document. images. oImage. src // document. images. name attribute. src
D) create an image
Var oImage
OImage = new Image ()
Document.images.oimage.src000000001.jpg"
At the same time, you can create an img/tag on the page to display it.
------------------------
Forms set (forms in the page)
A) reference through a set
Document. forms // form tag on the corresponding page
Document. forms. length // Number of/formform labels on the page
Document. forms [0] // 1st/formform labels
Document. forms [I] // The I-1/formform tag
Document. forms [I]. length // number of controls in the I-1/formform
Document. forms [I]. elements [j] // The I-1 control in the J-1/formform
B) direct reference through the label name attribute
/Formform name = "Myform"> input name = "myctrl"/>/form
Document. Myform. myctrl // document. form name. Control name
C) Access Form attributes
Document. forms [I]. name // corresponding form name> attribute
Document. forms [I]. action // corresponding/formform action> attribute
Document. forms [I]. encoding // corresponding/formform enctype> attribute
Document.formspolici2.16.tar get // corresponding/formform target> attribute
Document. forms [I]. appendChild (oTag) // dynamically insert a control
Document. all. oDiv // reference layer oDiv
Document. all. oDiv. style. display = "" // set the layer to visible.
Document. all. oDiv. style. display = "none" // The layers are hidden.
Document. getElementId ("oDiv") // reference an object through getElementId
Document. getElementId ("oDiv"). style = ""
Document. getElementId ("oDiv"). display = "none"
/* Document. all indicates the set of all objects in the document.
Only ie supports this attribute, so it is also used to determine the browser type */
Four attributes of a layer object
Document. getElementById ("ID"). innerText // dynamic output text
Document. getElementById ("ID"). innerHTML // dynamically output HTML
Document. getElementById ("ID"). outerText // same as innerText
Document. getElementById ("ID"). outerHTML // same as innerHTML
