 Q:

How can I have my website check the visitor's java installation and offer to update or install it?

I made a website (well, a pair of websites: MiningForJapan.org and MiningForJoplin.org) that allow visitors to contribute to a Bitcoin Mining Pool to benefit Red Cross relief efforts.
Anyway, the bitcoin mining code relies on the user's browser having an up-to-date and enabled Java runtime plugin, and the site doesn't look any different when it's not working.
How can I check that Java is running, and pop in a warning message with a link to download Java if the check fails?  The site is mainly written in PHP, if that matters (I don't see why it would).

A:

Sigh, well, whatever the deal is with donating CPU power, you can use http://java.com/js/deployJava.js, then
if (!deployJava.versionCheck("1.0")) {
  // Let pre-v1.0 users know what they're missing
}

The correct solution is to offer them a link to Java's download page, of course.

 Q:

Is there a JavaScript equivalent to "string". "string" in PHP?

I am currently learning a little bit of JavaScript and had a question.
In PHP, I am used to binding text and strings together with a simple dot like this:
echo "Text". $String. "anotherText". $anotherString

Is this possible in JavaScript? (Not the echo, but the binding of the strings and text.)

A:

The + is the concatenation operator in JavaScript:
"Text" + somestring + "anotherText" + anotherString;

A:

In JavaScript it's + instead of.
Example 1:
document.write("Text" + somestring + "anotherText" + anotherString);

Example 2:
alert("Text" + somestring + "anotherText" + anotherString);

Example 3:
var john = "Text" + somest
' (t)x=-c_1(t)y(t)x\\ 
 f_2(t, x)=y(t)\\ 
 f_{22}(t, x)=0
