Exploration and solution to the strange effect of setInterval when switching tabs in Firefox and Chrome! _javascript skills
In the previous article: I think the text scrolling in the lower left corner of Zhubajie.com works well, so I explored it myself and implemented it in my own way!
It has this effect, but it has little impact. The impact of the demo is huge!
Some people on the Internet have also had this problem. See the post address below:
Many people have discussed it, but no answer has been given.
I can’t figure it out no matter how much I think about it!
Today, something suddenly dawned on me. It may be the concept of threads, but I still don’t understand the specific reason. I hope someone knows the reason and can let me know. Thank you very much!
The black Div in the Demo is not affected by browser tab switching
The red Div will be affected.
HTML:
javascript:
(function(){
var elem = Meng.getId('move'),
elem2 = Meng.getId('move2'),
pos = Meng.getElemViewPosition(elem),
view = Meng.getBrowserView(),
//Gray block movement function
move = function(){
var t1 = Meng.animate(elem,{top:0,left:0} ,{top:view.height-100,left:view.width-100},3000,function(){
var t2 = Meng.animate(elem,{left:view.width-100},{left: 100-view.width},3000,function(){
var t3 = Meng.animate(elem,{top:view.height-100},{top:100-view.height},3000,function() {
move();//After confirming that t3 has finished moving, I call back the move() function
});
});
});
};
move();
//Red block movement function
Meng.setStyle(elem2,{top:0,left:(view.width-100) 'px'});
var move2 = function( ){
var t1 = Meng.animate(elem2,{top:0,left:view.width-100},{top:view.height-100,left:100-view.width},3000,function( ){
var t2 = Meng.animate(elem2,{top:view.height-100},{top:100-view.height},3000,function(){
var t3 = Meng.animate( elem2,{left:0},{left:view.width-100},3000,function(){
});
});
});
};
move2();
setInterval(function(){move2();},9050);
//Red block motion function
})();

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.
