HomeWeb Front-endJS TutorialVoting system display results plug-in based on jQuery_jquery

First, let’s take a look at the running effect, as shown in Figure 1.

Steps to use this plug-in
1. Import the css file
First, import the css style file 'votecss.css' into the page, which is necessary for the normal display of voting results. Less. The specific code is as follows:

2. The source file that introduces jQuery is the source file
The plug-in is based on jQuery, so the specific code required to introduce the jQuery plug-in is as follows:

3. Introducing the voting plug-in
Introducing the self-developed voting plug-in "Studyplay_vote.js", the specific code is as follows:

4. Page call
First add a div element with ID 'z' to the page and write JavaScript code to display the voting results. The specific code is as follows:
Copy Code The code is as follows:



The effect of running this code is shown in Figure 1.
Note: This plug-in has two parameters
1. Options is a required plug-in. It is an object data. The specific form is as follows.
[{},{}...{}]The number of this array is the number of voting options. If there are ten voting options, this array must be 10; {} is json data, there are three items in total .
"name" represents the name of the voting option;
"data" represents the number of votes for this option;
"color" represents the column color of this option.
2. The totle optional parameter can be omitted. Indicates the total number of votes cast, mainly used for calculating percentages for multiple choice votes.

The specific code of the plug-in
Copy the code The code is as follows:

$. fn.study_vote= function(options,totle){
var settings=options;
if(totle!=null)
{
if(isNaN(totle))
{
alert('Parameter error');
return;
}
}
if(typeof(settings)!='object')
{
alert('Parameter error') ;
return;
}
var container = jQuery(this);
container.html('
');
var study_voteCount=0;
if(totle==null||totle=='')
{//Single vote
for(i=0;i {
study_voteCount = parseInt(settings[i].data);
}
}
else
{//Multiple votes
study_voteCount = parseInt(totle);
}
var study_votestr="";
for(i=0;i{
var studyplay_present=settings[i].data/study_voteCount*100;
if(parseInt(studyplay_present)!=studyplay_present)
{
studyplay_present=studyplay_present.toFixed(2);
}
study_votestr ='
' settings[i].name ':
' studyplay_present '%
';
}
container.find('#studyvote').html(study_votestr)
}

JavaScript and the Web: Core Functionality and Use CasesJavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

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 the JavaScript Engine: Implementation DetailsUnderstanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

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 vs. JavaScript: The Learning Curve and Ease of UsePython vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

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 vs. JavaScript: Community, Libraries, and ResourcesPython vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

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.

From C/C   to JavaScript: How It All WorksFrom C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

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.

JavaScript Engines: Comparing ImplementationsJavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

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.

Beyond the Browser: JavaScript in the Real WorldBeyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

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.
