$(this).css('color', 'red');
Here is what the above code is Doing:
1. We’re selecting the element with the id of “my-element”
2. We’re changing the background color to blue
3. We’re changing the font color to red
Now, let’s see how we can do the same thing with jQuery:
// First, put on the blindfold // Second, use grepper to look up how to push to an array Here is what the above code is Doing: 1. It’s creating a variable called “my_array” and assigning it to an empty array. 2. It’s creating a variable called “my_string” and assigning it to the string “Hello,…
elementsCollection.forEach(function(element){ if (!element.shouldBeProcessed) return; // stop processing this iteration // This part will be avoided if not neccessary doSomeLengthyOperation(); }); Here is what the above code is Doing: 1. It’s iterating over the elementsCollection 2. It’s checking if the element should be processed 3. If it should be processed, it’s doing some lengthy operation The…
// in ./android/build.gradle ext { buildToolsVersion = “30.0.2” //
defaults: { … toolbar: [], // this will prevent its rendering on the component } Here is what the above code is Doing: 1. We are importing the CKEditor component from the ckeditor4-react package. 2. We are creating a new component called RichTextEditor. 3. We are using the CKEditor component and passing the data property…
typedef struct { unsigned char r, g, b; } RGB; double ColourDistance(RGB e1, RGB e2) { long rmean = ( (long)e1.r + (long)e2.r ) / 2; long r = (long)e1.r – (long)e2.r; long g = (long)e1.g – (long)e2.g; long b = (long)e1.b – (long)e2.b; return sqrt((((512+rmean)*r*r)>>8) + 4*g*g + (((767-rmean)*b*b)>>8)); } Here is what the…
Here is what the above code is Doing: 1. We’re using the v-bind directive to bind the style attribute to the color variable. 2. We’re using the :style shorthand to bind the color property to the color variable. 3. We’re using the color variable to set the color of the div.
