Vue Js Change Text Field Color Conditionally: In Vue.js, you can change the text field color conditionally by using class bindings. First, create a data property to hold the condition value. Then, use the v-bind directive to bind a class based on the condition. For example, if the condition is met, you can apply a CSS class that defines the desired text field color. Finally, use the v-model directive to bind the input value to a data property. Whenever the condition changes, the class will be applied or removed dynamically, reflecting the desired text field color accordingly.
How can I conditionally change the color of a text field in Vue js?
The Below code is using Vue.js to conditionally change the color of a text field based on the user’s input. The computed property textColor is used to determine the color dynamically based on the validation logic specified.
In this example, the validation logic checks if the userInput is empty or has a length less than 5 characters. If the condition is met, the text color is set to 'red', indicating an error. Otherwise, the text color is set to 'black'.

const app = new Vue({
el: "#app",
data() {
return {
userInput: '',
};
},
computed: {
textColor() {
// Add your validation logic here
// For example, check if the input is empty or doesn't meet certain criteria
return this.userInput === '' || this.userInput.length < 5 ? 'red' : 'black';
},
},
});
</script>
