Component Customization

Suggest Edits

Every component takes in an object which has options to control the behaviour and the look and feel of the component. Using the right parameters in options you can make sure the component matches the look of your web application.

Usage

let options = {}
let cardNumber = cashfree.create("cardNumber", options);
cardNumber.mount("#cardnumber")

The option object

let options = {
    classes: {},
    fonts: [],
    style: {},
    values:{},
    disabled: false,
    loader: true,
};

classes

Type: object

You can use classes which is an object that will have names of classes. The classes you specify will be applied to DOM container where the component is mounted. You have to make sure that these are present in your application css .

Important
Please note that you do not have to add the classes to your DOM container. The sdk will do it when required

Default values

{
    base: "cf-base-private",
    complete: "cf-complete-private",
    empty: "cf-empty-private",
    focus: "cf-focus-private",
    invalid: "cf-invalid-private",
    disabled: "cf-disabled-private",
}

base

The string you provide as a value of base will be applied to the container. This is the base class. If you do not provide a value of base, default value of cf-base-private will be applied

Example
Your js file

let options = {
	classes: {
		base: "my-base"
	}
}

Your css file

.my-base{
	padding: 5px;
}

Your HTML 

<div class="base" id="mount-here"></div>

In this case a padding of 5px will be added to your container once a component is mounted

complete

A complete class will be applied to the container when the component you have mounted has been completed by the customer. This is relevant for example in card number input box when the user has entered a valid card number you would want to make the border of your container green. Default is cf-complete-private.
Please note that not all components will have apply a complete class to your container.

Example
Your js file

let options = {
	classes: {
		complete: "my-complete"
	}
}

Your css file

.my-complete{
	border: 1px solid green;
}

Combining example of base and complete you can figure out that when the component is complete it will have two classes so css of both of the classes wil be applied which are

padding: 5px;
border: 1px solid green;

empty

An empty class will be applied to the container when the component being mounted is empty. Example would be card number not yet entered by the user means that the card number component will be empty and the empty class that you have specified will be applied. Default is cf-empty-private

Example
Your js file

let options = {
	classes: {
		empty: "my-empty"
	}
}

Your css file

.my-empty{
	box-shadow: 1px 1px 4px gray;
}

When empty a box-shadow will appear in your container

focus

This will be applied to your container when the element inside is focussed. Example would be user has focussed on the card number input area. Default is cf-focus-private

Example
Your js file

let options = {
	classes: {
		focus: "my-focus"
	}
}

Your css file

.my-empty{
	transform: translateY(-5px)
}

When focussed the container will move up by 5px

invalid

This will be applied when the component inside is invalid. For example the user has entered a wrong card number. Default is cf-invalid-private

Example
Your js file

let options = {
	classes: {
		invalid: "my-invalid"
	}
}

Your css file

.my-empty{
	border: 1px solid red;
}

When invalid the container will have a red border

disabled

This will be applied when you want the component inside the container to be disabled. Default is cf-disabled-private

Example
Your js file

let options = {
	classes: {
		disabled: "my-disabled"
	}
}

Your css file

.my-disabled{
	opacity: 0.8;
}

When disabled your container will be dimmer

fonts

Type: array

Using fonts you can make sure that the text inside component has the same font as your web application.

Default value

[]

There are two ways to specify fonts

  1. Using a absolute URL to a css file with @font-face definitions.F or example:
    https://fonts.googleapis.com/css?family=Open+Sans

Example

let options = {
	fonts: [{
		cssSrc: 'https://fonts.googleapis.com/css?family=Open+Sans'
	}]
}
  1. Using a absolute URL for a font file along with other parameters

Example

let options = {
	fonts:[{
		fontFamily: "Nova Mono",
		fontStyle: "normal",
		fontWeight: 400,
		fontDisplay: "swap",
		src: "url(https://fonts.gstatic.com/s/novamono/v18/Cn-0JtiGWQ5Ajb--MRKvZ2ZZj9AtSw.woff2)",
		unicodeRange: "U+0000-00FF, U+0131, U+0152-0153, U+02BB-02BC, U+02C6, U+02DA, U+02DC, U+2000-206F, U+2074, U+20AC, U+2122, U+2191, U+2193, U+2212, U+2215, U+FEFF, U+FFFD"
	}]
}

Required: src and fontFamily

You can specify multiple fonts and choose which to use in the component

style

Type: object

The style object is used to apply css properties to the contents of the component. It is different from classes in the fact that classes are used to apply css to the container that contains the component. There are 4 variants base, complete, empty and invalid.

You are free to add any css property by converting the propery type to camelCase and having the proerty value as string. Example being fontSize: '16px' for font-size: 16px

Default values

{
	base: {
		fontSize: "16px",
	},
	complete: {},
	empty: {},
	invalid: {
		color: "#C1292E",
	},
}

The following pseudo-classes and pseudo-elements can also be styled using a nested object inside of a variant:

  • :hover
  • :focus
  • :dsiabled
  • ::placeholder

Example

let options = {
	fonts: [{
		cssSrc: 'https://fonts.googleapis.com/css?family=Nova+Mono'
	}],
	style: {
	    base: {
	        fontSize: "18px",
	        fontFamily: "Nova Mono",
	        fontWeight: "300",
	        color: "#444",
	        backgroundColor: "transparent",
	        "::placeholder": {
	            color: "#2836d4",
	        },
	        ":hover": {
	            color: "#ff00ff"
	        },
	        ":focus": {
	            color: "#443231"
	        },
	        ":disabled": {
	            color: "#f0d865",
	            backgroundColor: "pink",
	        },
	    },
	    complete: {
	        color: "#7A9B76",
	    },
	    empty: {
	        backgroundColor: "#fff",
	        "::placeholder": {
	            color: "#4e9152",
	        },
