The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
It sounds like you either need:
ReplyDeleteif (file.exists() && readFileAndCheckForWhatever(file)) {
// File exists and contains the relevant word
} else {
// File doesn't exist, or doesn't contain the relevant word
}
or
if (file.exists()) {
// Code elided: read the file...
if (contents.contains(...)) {
// File exists and contains the relevant word
} else {
// File exists but doesn't contain the relevant word
}
} else {
// File doesn't exist
}
or reversing the logic of the previous one to flatten it
if (!file.exists()) {
// File doesn't exist
} else if (readFileAndCheckForWhatever(file)) {
// File exists and contains the relevant word
} else {
// File exists but doesn't contain the relevant word
}
Unless I am missing something, couldn't you just be using else if?
ReplyDeleteelse if((file.exists())&&(!file.contains(Whatever))) { ... }
File.contains would need to be exchanged for a function that actually checks the file, but you get the idea.
Maybe you mean something like:
ReplyDeleteif(file.exists() && containsLine(file))
{
// do something
}
else
{
// do something else
}
public boolean containsLine(File f)
{
// do the checking here
}
