Looking to enhance user input in a textarea? Want to change the color of specific words as they are typed by the user? For example, if you are expecting the user to type:
"My name is Maryam and My age is 24"
and you want to highlight 'My name' and 'My age' in blue as soon as they are typed. Additionally, you want these changes to be reflected inside the textarea itself.
Is there a way to achieve this using CSS, HTML or JavaScript?
Transforming a text area into colored text can be achieved by creatively utilizing CSS and JavaScript. One way to do this is by hiding the textarea element and displaying the colored text in another visible element.
Customize Your Text:
<textarea onkeyup="textChange()"></textarea>
<div id="colorText"></div>
Implement Javascript Function:
var textChange=function(){
var text=event.target.value;
if(text.indexOf("My name")>-1){
text=text.replace("My name", "<span class='blue'>My name</span>");
}
if(text.indexOf("my age")>-1){
text=text.replace("my age", "<span class='blue'>my age</span>");
}
document.getElementById("colorText").innerHTML=text;
}
Add Styling with CSS:
.blue{
color: blue;
}
Changing the color of text within an input field may not be possible, but you can create a preview feature that highlights specific words in different colors. One way to achieve this is by using a Regex statement to scan the text as characters are typed (utilizing a jQuery "Change" event). When certain words are detected, wrap them in html tags for styling in the preview window.
This strategy allows for dynamic coloring of desired words, enhancing the visual presentation of the input data. By applying CSS styles to these tags, you can customize the appearance of each highlighted word.
