In Vue, you can get the length of a string using the built-in length
property. You can access this property directly on a string data property in your Vue component.
Here’s an example of how to get the length of a string in Vue:
<template>
<div>
<input type="text" v-model="inputText" />
<p>The length of the input text is {{ inputText.length }}</p>
</div>
</template>
<script>
export default {
data() {
return {
inputText: '',
};
},
};
</script>
In this example, we have an input field that’s bound to the inputText
data property using the v-model
directive. We’re then using interpolation in the template to display the length of the inputText
string, which is obtained using the length
property.
You can also use computed properties in Vue to calculate the length of a string based on other data properties in your component. Here’s an example:
<template>
<div>
<input type="text" v-model="inputText" />
<p>The length of the input text is {{ inputTextLength }}</p>
</div>
</template>
<script>
export default {
data() {
return {
inputText: '',
};
},
computed: {
inputTextLength() {
return this.inputText.length;
},
},
};
</script>
In this example, we’re defining a computed property called inputTextLength
that calculates the length of the inputText
string using the length
property. We’re then using interpolation in the template to display the calculated length.
