This JavaScript function capitalizes the first letter of each word in a given string and assigns the result to an input element
That being said lets take a look at how this script looks like,
function toUpper(myString) {
// Capitalize each word using map
const newString = myString.split(' ')
.map(word => word.charAt(0).toUpperCase() + word.slice(1))
.join(' ');
// Update the input field with id 'keyword'
document.getElementById('keyword').value = newString;
return true; // For compatibility with form submissions
}
Using map:
- This simplifies transforming each word in the array.
charAt and slice:
charAt(0)andslice(1)improve readability compared tosubstring.
Assuming there’s an input field with the ID keyword,
<input type="text" id="keyword" value="">
<button onclick="toUpper(document.getElementById('keyword').value)">Capitalize</button>
Thanq So Much ….It Helps me alot
