vue max characters html input

To limit the maximum number of characters in an HTML input field using Vue, you can follow these steps:

1. Start by defining a data property in your Vue component to store the input value and track its length. For example, let's call it inputValue:

data() {
  return {
    inputValue: '',
  };
},

1. Next, add a v-model directive to your input field, binding it to the inputValue data property. This will enable two-way data binding, allowing you to access and modify the input value easily:

<input v-model="inputValue" type="text">

1. Now, you can display the current length of the input value to the user. Add a <span> element below the input field and use the inputValue.length property to show the length dynamically:

<input v-model="inputValue" type="text">
<span>{{inputValue.length}}</span>

1. If you want to limit the maximum number of characters allowed in the input, you can add the maxlength attribute to the input field. Bind it to a computed property that returns the desired maximum length. For example, let's call the computed property maxInputLength:

<input v-model="inputValue" :maxlength="maxInputLength" type="text">
<span>{{inputValue.length}}</span>

computed: {
  maxInputLength() {
    return 10; // Replace with your desired maximum length
  },
},

Now, the input field will only accept a maximum of 10 characters. When the user exceeds this limit, they won't be able to enter any more characters.

Please note that you should replace the 10 in the maxInputLength computed property with your desired maximum length. Also, don't forget to adjust the example code to fit into your Vue component structure.
