interact.js Javascript Library

Previously we've discussed enabling the drag and drop functionalities using the jsPlumb library. Recently, I stumbled upon the interact.js Javascript library, which I found to be as user-friendly as jsPlumb.

Below is a short comparison of the two.

The above details are not presented here to render either one as the bet over the other. 

But, in my own experience, I've blended both in my projects utilizing the drag and drop functions for some elements from jsPLumb and the drag and resize function for one element from inter.js. But the only concern when using both the libraries within one function, issues related to the drag function of jsPlumb and interact.js overriding each other bringing out an unintentional effect, needs to be handled. I my case, I removed the jsPlumb's draggable enforced on the element considered in that context and enabled the interact.js's draggable only for this particular instance. 

Here's an example of how I've included interact.js in implementing the drag, drop and resize functionalities.

resizable Function





Here, ".partitiondrop" is the class of the element that I need the preceding function to be enforced on. Most of the explanations are provided within the code itself in the form of comments.

AngularJS vs ReactJS

Image
Today I just came across an interesting question and thought of creating this. At many occasions, developers try to render ReactJS as the best over AngularJS. But, according to my personal opinion, this is purely opinionated and also strongly depends on the type of the project in context. First of all, here's a very brief definition of what AngularJS & ReactJS according to their documentations. AngularJS AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML's syntax to express your application's components clearly and succinctly. Angular's data binding and dependency injection eliminate much of the code you would otherwise have to write." Here's a perfect example to try out this. ReactJS   React.js is a JavaScript library for building user interfaces. (Famously used by Facebook) The comparison between the two has been jotted out in the following table

Creating connections between Elements in jsPlumb

In my previous posts we've gone through creating a toolbox and canvas from which elements can be dragged from and dropped onto. Then we took a look at eliminating the replication of elements whenever a dropped clone was dragged within the canvas. So now let's move onto creating basic connections between these dropped elements using jsPlumb and jQuery-UI. Starting off with the code previously dealt with, creating connections requires only the addition of a few lines of code to your JS code. The droppable function part of the code has been shown below. Step 1: Assign a unique ID for each element being dropped on the canvas. Though jsPlumb will automatically assign an ID when you don't supply one, it is easier to manipulate the elements when you define an ID. This ID can be a simple digit or even a complex string( But remember, jsPlumb treats all IDs as strings). //Set a unique ID for each dropped Element var indexer = 0 ; function setId (element){ indexer ++;
