找不到处理文件

Question

I have a link say TestLink.

Clicking on which normally yields me a pdf. Sometimes it diplays a page in a new window with message file not found

I need to respond when second case happens ,how do i handle this case via javascript?

Answer 1

You could use jQuery

$.ajax( "http://link.to.pdf" )
 .fail(function() {
     // ... disable the link --> PDF is not reachable
 });

source

You can check the link, if the PDF is not reachable disable the link.
