Javascript content printing method summary _ javascript skills

About JS printing! Online collection + self-Summary. For more information, see. Window. print () is used for general printing.
However, this method is usually used for selective printing. Therefore, the following method is called:

The Code is as follows:

Function preview ()
{
Bdhtml###doc ument. body. innerHTML;
Sprnstr =" ";
Eprnstr =" ";
Prnhtml = bdhtml. substr (bdhtml. indexOf (sprnstr) + 17 );
Prnhtml = prnhtml. substring (0, prnhtml. indexOf (eprnstr ));
Too many Doc ument. body. innerHTML = prnhtml;
Window. print ();
}

The problem is coming again ~
There will be footer and header ~ There are also horizontal and vertical points ~
What should I do?
It is best to use print preview ~
Because it has settings
In this case, an IE control "WebBrowser" must be referenced"
Reference in the page:


Its control method:

The Code is as follows:

WebBrowser. ExecWB () Open
WebBrowser. ExecWB () Close all existing IE Windows and open a new window
WebBrowser. ExecWB () Save the webpage
WebBrowser. ExecWB (6, 1) print
WebBrowser. ExecWB (7,1) print preview
WebBrowser. ExecWB (8, 1) print page settings
WebBrowser. ExecWB (10, 1) view page properties
WebBrowser. ExecWB () seems to be undo, to be confirmed
Select All WebBrowser. ExecWB (17,1)
WebBrowser. ExecWB (22, 1) Refresh
WebBrowser. ExecWB () Close form no prompt

Example:

Print Test

Copy and paste any text file ~ Change the suffix ~
Ie running ~ Click Preview ~ Set printing ~ Print ~ OK
And then test it in the project ~ For example, in aspx
Run the same job. Click Preview ~
Region ~ How can I see the ie Security Warning "internet explorer" has blocked this site from using ActiveX controls in unsafe ways"
At this time, we need to change the security settings of ie (if no patch is installed, it will be okay ~ That is your "rp", not necessarily the customer and other people's "rp" is as good as you)
Operation:
Main Menu "Tools" -- Internet Options -- Security -- Custom Level, initialize the ActiveX control that is not marked as secure in "Security Settings" and run the script from "disabled" to "enabled"
Another method is to use "Tools" "Internet Options" "Trusted Sites (Trusted Sites)" "sites" and enter the website address. If the website is not based on https: for the connection, remove the check box before "require server verification (https :) for all sites in the region.
(For LAN: "tool" "Internet option" "local Internet" "advanced ")
(The wireless network does not seem to be a LAN)
Recommendation 2 ~
Everything is ready ~ OK ~
Print the method set (not tested one by one ):

The Code is as follows:

JS implements local printing and preview:
First:
JS to implement simple partial page Printing

The Code is as follows:

Function preview (preview)
{
If (then <10 ){
Bdhtml###doc ument. body. innerHTML; // obtain the html code of the current page
Sprnstr =" "; // Set the start area for printing.
Eprnstr =" "; // Set the print end Area
Prnhtml = bdhtml. substring (bdhtml. indexOf (sprnstr) + 18); // retrieves html from the start code
Prnhtml = prnhtml. substring (0, prnhtml. indexOf (eprnstr); // retrieves html from the end code
Too many Doc ument. body. innerHTML = prnhtml;
Window. print ();
Required parameter Doc ument. body. innerHTML = bdhtml;
} Else {
Window. print ();
}
}
