Javascript control web printing (partial printing) method arrangement _ javascript skills

This article provides some common web printing and local printing methods for emergency purposes. First, define the css style:

The Code is as follows:

@ Media print {
. Noprint {display: none; color: green}
}

You only need to add class = noprint to the label for the content that you do not want to print. During the printing, the customer will not see any changes on the page.

When printing, replace the content to be printed with the entire body content (the user will see the changes during printing, and the customer experience is not good)

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
