window print method is not working in ipad chrome browser

问题

I have the following code:

<input type="button" value="Print" onclick="window.print(); return false;">

Which works in all browsers but it is doing nothing ( not opening print dialog box ) in ipad chrome browser.

How can I solve this problem?

However if I do manually print with chrome settings print then its working.

回答1:

Multiple questions on SO show (1, 2, 3) that it's currently not possible to print in Chrome for iOS due to Apple's policy on using alternative browser engines.

Another solution is to use a third-party printing service: http://www.printfriendly.com

It's a chrome bug/feature. window.print is available, it works and do nothing. Try this code:

try {
    window.print()
}catch(e) {alert(e.message)}

The alert will not be shown. Also class UIWebView can use UIKit Printing API

P.S. Chrome using UIWebView.

Try this:

function goPrint(){
    window.print();
    if(navigator.userAgent.toLowerCase().indexOf('chrome') > -1) {
        window.location.reload();
    }
}
