Problem:
I encountered a problem when developing a project earlier. After the ajax asynchronous request is successful, a new window needs to be opened to open the url. The window.open() method is used, but unfortunately it is intercepted by the browser. Okay, how to solve this problem?
Analysis:
The reason why the browser intercepts the newly opened window is because the operation is not actively triggered by the user, so it thinks it is unsafe and intercepts it (but if it is _self, it will not There will be this limitation), even if the user behavior such as click or submit is simulated in the ajax callback function (trigger('click')), the browser will think that it is not actively triggered by the user, so it cannot be executed safely, so it is intercepted.
Solution:
1. Change asynchronous to synchronous, that is: async:false
2. Point the newly opened window to an object, and then modify the url of the object, such as:
$('.task').bind('click',function(){ var w = window.open(); $.ajax({ type: 'POST', url: '/surveyTask', dataType: 'json', error: function(){ w.close(); }, success: function(res){ w.location = res.url; } }); });
The last thing that needs to be explained is: the online method of dynamically adding a form and opening a new window is not suitable for ajax requests. At least the blogger tested it and it was still viewed. intercepted by the device.

JavaScript core data types are consistent in browsers and Node.js, but are handled differently from the extra types. 1) The global object is window in the browser and global in Node.js. 2) Node.js' unique Buffer object, used to process binary data. 3) There are also differences in performance and time processing, and the code needs to be adjusted according to the environment.

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.
