Node. js cycle traps
The asynchronous mechanism of Node. js is implemented by events and callback functions. It may feel like a violation of the Conventions at the beginning, but it will be very easy to get used to later.
However, there are actually many traps hidden in this process. A very easy problem is to return to the loop callback function.
Eq:
Var fs
JS cycle li add Click Event (Closure application), jsli
If you don't talk much about it, paste the Code directly. The specific code is described as follows:
Var aLi = document. querySelectorAll ('. article-tab li '); for (var I = 0; I
The above section describes how to add click events (Closure applications) in JS loop li. I hope this will be helpful to you.
How can we show one string on the DOM, and a completely different string on Console log? This lesson shows what we can make our main function return multiple observables, each one targeted at a different type of Effect.//Logic (functional)functionMain () {return{DOM:Rx.Observable.timer (0, +). Map (i =' timer is ${i} '), Log:Rx.Observable.timer (0, +). Map (i =i)};i}functionDomeffect (text$) {text$.subscribe (text={Const container= Document.queryselector (' #app '); Container.textcontent=text; }
I use it for practice, with detailed notes, and if there are friends who like me and want to learn Dom effects, it is recommended to first understand the contents of the HTML Dom object part of JavaScript, including common methods and properties.Here is recommended a description of JS knowledge architecture is a very strong site, can be used as the usual reference tool table-http://dreamdesign.csrjgzs.com/article/showarticle.asp?/4032-1.htmlJS Text ef
The following code is used to do the front-end statistics:The first block of code is used to multiply the unit price of each item in the ordergoods_table and the corresponding quantity, and finally assigns the result to Ordergoodsamount.The second block of code is used to add the quantity of all corresponding goods in the ordergoods_table to the total number of items, and finally assigns the result to TotalCount.How does JavaScript result in numerical calculations forcing the use of scientific n
Nonsense not much said, directly to everyone to paste the code, the specific code as follows:
var aLi = Document.queryselectorall ('. Article-tab li ');
for (var i = 0; I
The above is a small series to introduce the JS cycle Li Add Click event (Closure of the application), I hope to help you, if you have any questions welcome to my message, small series will promptly reply to everyone.
The example in this article describes the method of JS simple test cycle running time. Share to everyone for your reference, specific as follows:
