Following the study of scrollable last time, today we continue to study the fourth function of the six major functions of jquery tools - overlay.
For scrollable learning, first give the html target code of the operation:
Here is my overlay

>close
This function is implemented through the jqueryObject.overlay() method, where The overlay method provides the following two methods:
1. $("button[rel]").overlay()//This method can use the default method to display the prompt overlay 2. $("button[rel]" ).overlay({config object}) //This method will customize the overlay display through the configuration object.
The following code is the configuration parameter implementation of the second method (just put the implementation in the ready method of jquery):
Copy code
The code is as follows :
$("#overlay").overlay({api:true}).load();//Automatically display overlay, (no need to trigger, it will be automatically triggered when the page is loaded)
$ ("button[rel]").overlay({
start:{
width: 300,
absolute: false
},
finish:{
top:10,
left:400,
absolute:false
},
speed:3000,
fadeInSpeed:3000,
closeOn Click: false,
oneInstance:false,
close: '#overlayClose',//Customize the close button
. Function configuration item mode setting
:function(){
//alert(this .getTrigger().attr("rel") ":onBeforeLoad");//Display the trigger rel attribute value of the overlay prompt box (this.getTrigger().attr("rel") ":onLoad");
},
onBeforeClose:function(){
alert(this.getTrigger().attr("rel") ":onBeforeClose");
return false;
Attributes
In addition, the tooltip also provides a series of methods for obtaining overlay objects. The specific usage methods are as follows:
Copy code The code is as follows:
var overlayObj=$("#overlay").overlay({api:true});
overlayObj.load();//Automatically display overlay, (no need to trigger, it will be loaded on the page Automatically triggered when completed)
setTimeout(function(){overlayObj.close();},2000);//After 2 seconds, the automatically loaded (appeared) prompt box will be hidden
$("#overlayInfo") .append("
overlay is opened:" overlayObj.isOpened() "
");//Determine whether there is an overlay prompt box displayed at this time. append("
overlay background image:" overlayObj.getBackgroundImage() "
"); getTrigger () ""); );$("#overlayInfo").append("
overlay content:" overlayObj.getContent().html() "
"); OnbeforeLoad = Function () {Alert (this.getContent (). Attr ("ID");
}
The following is the description of the Overlay object description:
Default value | Description | |
load() | Overlay | Another way to open the overlay prompt box, through this method you can not pass The page event is triggered and the overlay prompt box is opened directly through the js script. |
close() | Overlay | (via the call to this method from the js script) close the pop-up overlay prompt box. |
isOpened() | boolean | Determine whether there is currently an overlay prompt box opened. If the overlay prompt box is currently opened, return true. |
getBackgroundImage() | jQuery | Return the background image of the current overlay prompt box as a jquery object. |
getContent() | jQuery | Return the content of the overlay pop-up box as a jquery object. |
getTrigger() | jQuery | The element that will trigger the overlay popup box is returned as a jquery object. |
getConf() | Object | Get the configuration object of overlay when the popup box is initialized. |
api | FALSE | Same as api in configuration object. |
onBeforeLoad(fn) | API | Same as the onBeforeLoad attribute in the configuration file. |
onLoad(fn) | API | Same configuration file in onLoad attribute. |
onBeforeClose(fn) | API | Same configuration file in onBeforeClose attribute. |
onClose(fn) | API | Same configuration file in onClose attribute. |
Finally, the complete sample code is given:
Copy the code The code is as follows:
br/>"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
$("#overlayInfo").append("
overlay background image:" overlayObj.getBackgroundImage() "
");$("#overlayInfo").append("
overlay trigger:" overlayObj.getTrigger() "
");$("#overlayInfo").append("
overlay config-speed:" overlayObj.getConf().speed "
");$("#overlayInfo").append("
overlay content:" overlayObj.getContent().html() "
");overlayObj.onBeforeLoad=function(){
alert(this.getContent().attr("id"));
}
});

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.

The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.

JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.

Python is more suitable for data science and machine learning, while JavaScript is more suitable for front-end and full-stack development. 1. Python is known for its concise syntax and rich library ecosystem, and is suitable for data analysis and web development. 2. JavaScript is the core of front-end development. Node.js supports server-side programming and is suitable for full-stack development.

JavaScript does not require installation because it is already built into modern browsers. You just need a text editor and a browser to get started. 1) In the browser environment, run it by embedding the HTML file through tags. 2) In the Node.js environment, after downloading and installing Node.js, run the JavaScript file through the command line.
