JQuery Ajax Cache Cache Problem _jquery

In jquery, with $.ajax.
Then, when you specify an AJAX attribute, you use: ' false '.

This is where the hateful JavaScript feature comes in.

In jquery, for most of the time, attributes are used to "cause".
Otherwise it is easy to become a variable name. Red, for example, is not the same as the lead. But it can also be recognized as a cause. So the habit is all right.


However, false is a special case.
If caused, the result:
' false ' is treated as true. Because only the empty string is true.


For example: in the browser address bar, enter:
Javascript:alert (' false '? ') True ': ' false ');
The result will be: true.


Direct result: Ajax requests do not request again, but to slow access. And I think the results will be very different ....
