To detect if the jquery library is already loaded, you can use the following JavaScript code:
if (typeof JQuery! = ' undefined ') {
Alert ("JQuery library is loaded!");
}Else{
Alert ("JQuery Library is not found!");

Another option.
In some blogs and forums it is mentioned that you can use code to achieve the same purpose.
If
Alert ("JQuery library is loaded!");
}Else{
Alert ("JQuery Library is not found!");
}

Our computer in the use of a long time after the hard drive will inevitably appear bad, if the hard drive has bad road will affect the operation of the computer or even lead to data loss, then timely detection of the hard drive and repair the bad road is very necessary, the following small series to teach you LU master to detect hard drive bad way.
1. After opening the main menu interface of Master Lu, note the lower right corner, such as arrow posit
cases, you know how to encode a document that you write. However, if you are not writing a document-just a document that you receive from another place (for example, from an Atom feed)-then the best approach is to use a streaming API, such as simple APIs for XML (SAX), streaming API for XML (StAX), System.Xml.XmlReader or Xerces Native Interface (XNI). In addition, you can also use a tree API, such as the Document Object Model (MODEL,DOM). However, they need to read the entire document, even if

Console.log (typeof new RegExp ());//object
Console.log (typeof new Error ()); Object
Console.log (typeof new Person ())/////object is also object with typeof detection
To use instanceof to detect:
var date = new Date ();
var reg = new RegExp ();
var err = new Error ();
var me = new Person ();
if (date instanceof date) { //detection date Year
= Date.getfullyear ();
}
if (reg instanceof RegExp) { //det
Js Object-Oriented Programming: how to detect object types and js Object-Oriented Programming

In the last two years, security experts should be more focused on attacks on the network application layer. Because no matter how strong your firewall rule setting or the most diligent patching mechanism is, if your Web application developer does not follow the security code for development, the attacker will enter your system via port 80. The two main attack techniques that are widely used are SQL injection [REF1] and Css[ref2] attacks. SQL injection refers to the technique of inserting sqlmeta
In the study of an image, there are often planar or linear problems, and the lines are frequently visible in the image. These meaningful features play an important role in the process of image processing such as object recognition. This section mainly records a classical detection line algorithm-Hough transform (Hough Transform), using Hough transform to detect the line and circle in the image, the development platform is qt5.3.2+opencv2.4.9.One: Houg
