Ensure that the input field requires the first letter to be capitalized and the subsequent letters to be in lowercase

There are numerous ways to capitalize the first letter and make the rest lowercase on Stack Overflow. However, I am looking for a method that can instantly enforce this rule in the input field.

Being new to AngularJS, I am currently working with version 1.7.x.

I came across the following code snippet, but unfortunately, it is not functioning as expected.

oninput="this.value = this.value.toUpperCase(0) + this.value.substring(1)"

Answer №1

I find it interesting that your approach involves having the JavaScript code directly in the string. A different method could be more efficient:

let capitalizedValue = this.value.charAt(0).toUpperCase() + this.value.slice(1);
this.value = capitalizedValue;

Answer №2

I suggest avoiding the use of JS for this task.

Instead, opt for CSS or utilize Bootstrap classes.

Here is a CSS example:

.capitalize {
   text-transform: capitalize;
}

Implement it in your HTML code like so:

<span class="capitalize">{{ yourModelName }}</span>

UPDATE 1: An alternative way using Bootstrap:

<p class="text-capitalize">CapiTaliZed text.</p>
