jquery implements the method of displaying a prompt box when the mouse slides over it_jquery
The example in this article describes the jquery method of displaying a prompt box when the mouse slides over it. Share it with everyone for your reference. The details are as follows:
1. Example of jquery prompt box displayed when the mouse slides over
1. Rendering
2. Implementation code (you need to add jquery.js, button images, and prompt box images by yourself)
HTML code
2. Example 2 of jquery prompt box displayed when the mouse slides over
When the mouse moves over the user name, a div will be displayed in the lower right corner of the mouse to display the user information
1. Rendering
2. Implementation method
There are only three big parts. One is the positioning of the div, which is the main difficulty of the effect; the second is asynchronous loading of data through ajax; the third is to use the two js attributes onmouseover and onmouseout, that is, when the mouse passes and mouse away.
3. Implementation steps
(1) First, design the style of the div to display user information. What should be noted here is that this method is not to bind a div next to each user name. It will be displayed when the mouse passes over it and hidden when the mouse leaves. There is only one div in the web page that displays information. It is positioned wherever it needs to be displayed. To do this, you need to set the positioning method of the div to absolute positioning.
HTML code:

(2)、相应css代码
width:380px;
height:160px;
float:left;
display:none;
border: 1px solid #ccc; position: absolute; z-index: 1; opacity: 0.1; background: white
}
.pic{
width:100px;
height:100px;
border:1px solid #ccc;
border-radius:10px;
float:left; margin:10px;
overflow:hidden;
}
.box{
width:240px;
height:140px;
margin:10px 0 10px 10px;
float:left;
overflow:hidden;text-overflow:ellipsis; white-space:nowrap;}
(3)、定位,为了能够精确的定位并且能够方便的调用,所以先在页面中放了两个标签,分别用于保存当前鼠标的坐标
然后用js获取当前坐标并保存到标签中:
$(document).mousemove(function (e) {
document.getElementById("pagex").value = e.pageX;//pageX() 属性是鼠标指针的位置,相对于文档的左边缘。
document.getElementById("pagey").value = e.pageY;//pageY() 属性是鼠标指针的位置,相对于文档的上边缘。
});
});
(4)、鼠标经过和离开事件js代码
$("#blockdiv").css({
"display": "block",
"left": document.getElementById('pagex').value,
"top": document.getElementById('pagey').value,
});
$("#messagediv").css("display", "block");
$.getJSON("../ashx/GetUserInfo。ashx?name=" username,
function (data) {
if (data != null) {
$("#lblusername").html(data[0].User_Count)
$("#lblrealname").html(data[0].User_name);
$("#sex").html(data[0].User_Sex);
$("#lbladdress").html(data[0].User_Address)
$("#lblemall").html(data[0].User_Email);
if (data[0].User_HeadImg != null&&data[0].User_HeadImg != "") {
$("#imguserhead").attr("src", "../../Users/" data[0].User_HeadImg.toString().substring(3));
}
else {
$("#imguserhead").attr("src", "../../Users/images/900.png");
}
$("#messagediv").css("display", "none");
}
else
$("#messagediv").html("未加载到数据!");
});
}
function HiddenInfo() {
$("#blockdiv").css({
"display": "none",
});
$("#lblusername").html("")
$("#lblrealname").html("");
$("#sex").html("");
$("#lbladdress").html("")
$("#lblemall").html("");
}

希望本文所述对大家的jQuery程序设计有所帮助。

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

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.
