HomeWeb Front-endFront-end Q&AWhat is the difference between jquery and ajax in vue

Difference: 1. The ajax method in jquery can be called directly, but it cannot be called directly in vue, because vue itself does not support ajax requests and needs to be implemented with the help of a specified plug-in; 2. Asynchronous HTTP is executed in jquery Request, the syntax is "$.ajax({type:...,url:...,data:...,success:...,dataType:...})", and vue uses the syntax of the plug-in is "axios.get(url...)".

What is the difference between jquery and ajax in vue

ajax in jQuery

ajax() method is used to perform AJAX (asynchronous HTTP) requests .

1.$.ajax() is the bottom-level ajax implementation in jQuery, and the higher-level ones are the $.get and $.post methods;

$(document).ready(function(){
  $("#b01").click(function(){
  htmlobj=$.ajax({url:"/jquery/test1.txt",async:false});
  $("#myDiv").html(htmlobj.responseText);
  });
});

2.$.get method, when the request is successful If you want to have an operation when the request fails, use $.ajax()

$(selector).get(url,data,success(response,status,xhr),dataType)
$("button").click(function(){
  $.get("demo_ajax_load.txt", function(result){
    $("div").html(result);
  });
});

is the abbreviation of $.ajax

$.ajax({
  url: url,
  data: data,
  success: success,
  dataType: dataType
});

Example:

3.$.post method

$("input").keyup(function(){
  txt=$("input").val();
  $.post("demo_ajax_gethint.asp",{suggest:txt},function(result){
    $("span").html(result);
  });
});

is the abbreviation for the following

$.ajax({
  type: 'POST',
  url: url,
  data: data,
  success: success,
  dataType: dataType
});

4.$.getJSON()

Obtain json data through HTTP get request

5. Two important methods

.serialize( ) Serialize the form content into a string;

.serializeArray() Serializes the form elements and returns JSON data structure data.

Ajax in VUE

vue itself does not support ajax requests, you need to use vue-resource, axios plug-in

vue2 officially recommends axios, which is a Promise-based HTTP request client will no longer maintain and update vue-resource;

axios([options])  
axios.get(url[,options]);

Parameter passing method:

1. Pass parameters through url

2. Passing parameters through params options

axios.post(url,data,[options]);

When axios sends data by default, the data format is Request Payload, which is not our commonly used Form Data format.

Therefore, the parameters must be passed in the form of key-value pairs, and cannot be passed in the form of json

Parameter passing method:

1. Splice them into key-value pairs yourself

2. Use transformRequest to convert the request data before sending the request

3. If you use modular development, you can use the qs module for conversion

axios itself does not support sending across There is no corresponding API provided for domain requests, and the author has no plans to add support for sending cross-domain requests in axios, so we can only use third-party libraries

HTML and React's Integration: A Practical GuideHTML and React's Integration: A Practical GuideApr 21, 2025 am 12:16 AM

HTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.

React and HTML: Rendering Data and Handling EventsReact and HTML: Rendering Data and Handling EventsApr 20, 2025 am 12:21 AM

React efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.

The Backend Connection: How React Interacts with ServersThe Backend Connection: How React Interacts with ServersApr 20, 2025 am 12:19 AM

React interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.

React: Focusing on the User Interface (Frontend)React: Focusing on the User Interface (Frontend)Apr 20, 2025 am 12:18 AM

React is a JavaScript library for building user interfaces that improves efficiency through component development and virtual DOM. 1. Components and JSX: Use JSX syntax to define components to enhance code intuitiveness and quality. 2. Virtual DOM and Rendering: Optimize rendering performance through virtual DOM and diff algorithms. 3. State management and Hooks: Hooks such as useState and useEffect simplify state management and side effects handling. 4. Example of usage: From basic forms to advanced global state management, use the ContextAPI. 5. Common errors and debugging: Avoid improper state management and component update problems, and use ReactDevTools to debug. 6. Performance optimization and optimality

React in the HTML: Building Interactive User InterfacesReact in the HTML: Building Interactive User InterfacesApr 20, 2025 am 12:05 AM

React can be embedded in HTML to enhance or completely rewrite traditional HTML pages. 1) The basic steps to using React include adding a root div in HTML and rendering the React component via ReactDOM.render(). 2) More advanced applications include using useState to manage state and implement complex UI interactions such as counters and to-do lists. 3) Optimization and best practices include code segmentation, lazy loading and using React.memo and useMemo to improve performance. Through these methods, developers can leverage the power of React to build dynamic and responsive user interfaces.

React: The Foundation for Modern Frontend DevelopmentReact: The Foundation for Modern Frontend DevelopmentApr 19, 2025 am 12:23 AM

React is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.

The Future of React: Trends and Innovations in Web DevelopmentThe Future of React: Trends and Innovations in Web DevelopmentApr 19, 2025 am 12:22 AM

React's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.
