JavaScript { Part 14.2 : Libraries } – codeburst

  • IntlThis is a global object, yes and object!
  • (More info here)Previously I said that the Intl is an object and actually most of the functionality is accessed by that object Intl, you need to remember that in order to use it and three main word methodsWhen can you use it?Actually most of the browsers support it, but to be…

#StackBounty: #javascript #css #reactjs Update Redux prop/state following div onclick – TechUtils.in

#StackBounty: #javascript #css #reactjs Update Redux prop/state following div onclick

  • Table 2 displays data relevant to the clicked row in table 1.
  • The idea for the solution: “change margin-right” according to conditions which show whether the scroll exits or not.Save the result of this condition into Redux prop:

    element.scrollHeight > element.clientHeight || element.scrollWidth >

    element.clientWidth

    The problem: Trying to update the display/non-display of the scroll into redux prop from different React events such as componentDidMount, (set state causes infinte loop here) and from the click event.Tried to use forceUpdate() after setting props into Redux as well.

  • When console.log into the console in chrome (F12), the only result which is correlated correctly to the display/non display of the scrollbar is coming from within the componentDidUpdate and it doesn’t reflect in the redux prop (isoverflown function returns true, redux this.props.scrollStatus and this.state.scrollStatus are false).
  • Also don’t like the usage of document.getElementById for the div which contains the rows, because it breaks the manipulation of the dom from within the props and state,but didn’t find a different solution for now.
  • The F12 console when display the scroll bar:

    The F12 console when no scroll bar is displayed:

    .

I have a table – let’s call it table 1. When clicking on a row in table 1 another table is being displayed, let’s call this one table 2. Table 2 displays data relevant to the clicked row in table 1. Sometimes a vertical scroll needs to be displayed in table 2 and sometimes not -depends on the number of rows.Need to solve: there is an unwanted transition of the border when the scroll is not being displayed:

Async/Await into React…… – codeburst

Async/Await into React……  #javascript #async #asyncawait #reactjs #react #reactjs

  • If we ponder more on asynchronous requests, they are requests made from our web page to some activity which is going to take it’s own time to respond.
  • After mounting the described UI to the DOM, it goes ahead and asks the free willed activity : — -Requesting the Free Willed ActivityAnd meanwhile our free willed activity is likeUnfortunately, our highly energetic react component will have to depend on promises.
  • Each of those nodes when clicked can produce more nodes by fetching more data from server.Package dependenciesNow our new componentSo handleNodeClick is the method which is invoked every time a node is clicked in the Network component.We have defined the function to be asynchronous by adding the keyword async before the function definition.
  • The keyword await is used to wait for the activity which here is a promise of fetching data from remote server.
  • The function is asynchronous and it waits for a promise to complete and then continues with normal execution.

Magic is what Async/Await bring to the table for handling asynchronous requests. If we ponder more on asynchronous requests, they are requests made from our web page to some activity which is going…

Create Beautiful Charts in #iOS using React Native -  by @spritlesoftware #apps #appdev

  • now you can access the charts anywhere inside your application using require like this
  • Now all of that done lets look at the charts component code , to use the chart you need to first specify the chartData (now i have kept is static) and also the labels for x-y axis Lets see how we can do that.
  • The package will be installed inside the node_modules inside your current path
  • Charts are getting important in our applications day by day , users now prefer diagrammatic representations that looking at a table and understanding the data flow , is a little demonstration of how we can implement charts in iOS using react native .
  • To install and configure react-native-charts please follow the following procedures
