, undefined, or null, it is equivalent to new Object (param), And param is the user-passed parameter.
2. Otherwise, an object is returned. For the type of the object to be converted, see the following table. The example above is essentially equivalent to new Number (123 ):
3. Simple Test Cases
The Code is as follows:
Var num = Object (123 );Console. log (typeof num); // output: object console. log (Object. prototype. toString. call (num); // output: [object Number]
Iii. var num = 123; and

Another In-Place Editor is a jQuery plugin that turns any element or group of elements into an Ajax in-place editor using only one line of code. it's written using the jQuery Library, which is available free at http://jquery.com.

Okay: This is very simple. There is nothing to introduce. Let's start to explain how this thing is implemented. However, we have to review it before talking about implementation, the results analyzed in the first article.

However, happy 001's multi-line verification of J100 involves a large number of bitwise operations, and the implementation of bug-free in Java still requires a considerable amount of work.
After careful consideration, I thought: if Javascript can be called in Java, can I directly call the JS function to generate rpasswd? Soon I f

The solution, of course, is the Jrunscript utility that the JDK brings, as shown in Listing 2:
