Hidden and irrelevant websites
This kind of hidden website is generally used in a main website.Window. open ()To open a ticket.,The purpose is to omit the feature columns of the window.,Fast and easy to collect,For exampleIndex.htmlHas the following program example:
Window. Open ("Hide.htm","Win2",
"Menubar = 0, toolbar = 0, location = 0, directories = 0, status = 0, scrollbars = 0, Height = 0, width = 0 ");
This is to open a new window for loadingHide.htm,Nothing is attached to this new window.,Both height and degree of Parallelism0.
InHide.htmYou can set the following parameters::
<HTML>
<SCRIPT>
Function hideit ()
{Window. resizeTo (0, 0 );
Window. moveTo (2000,2000 );
}
</SCRIPT>
</Head>
<Body onload ="Hideit(); "Onresize ="Hideit(); "Onmove ="Hideit();"
OnUnload = "zookeeper open('hide.htm');">
</Body>
In this case<Body> SetOnload(Opening a window),Onresize(Resize window),Onmobve(Dynamic Location of window Movement)All will be activeFunctionHideit (),InFunctionHideit () The primary actions are the primary key window and2000,2000.
What will I do after the website is hidden??The most common thing is time.(For example, every five minutes)An alert is displayed in the response window.,This process is closed,There will be a chapter later saidSetTimeout () OrSetinterval (),Use these twoMethod,You can configure the One-Stop function at a time.
Note: When the timer is shut down,The system remembers the size and location of the window when the window is closed.,If the latest connector isHide.htm,When the later timer is enabled, it will be smaller and moved2000,2000Location,If this happens,Is there any simple solution to this problem??Show answer
Use the notebook to setHtmCase,Inside<SCRIPT>SetWindow. resizeTo (600,600)AndWindow. moveTo (0, 0),Then the case will be opened in "President of the case ".
