How can I use Vue class binding to apply multiple conditions to a single element?
In the example, Vue class binding is used to apply multiple conditions to a single element. The v-bind:class directive is used to dynamically apply a class to the div element based on the values of the isActive, isError, and isDisabled data properties.
Here's an explanation of how the class binding works in this example:
- The
activeclass is applied whenisActiveistrue. - The
errorclass is applied whenisErroristrue. - The
disabledclass is applied whenisDisabledistrueandisErrorisfalse.
This means that the div element can have multiple classes applied to it at the same time, depending on the values of these data properties.
To use Vue class binding to apply multiple conditions to a single element, you can use the v-bind:class directive followed by an object containing the class names as keys and their corresponding conditions as values

<div id="app"> <div class="container" v-bind:class="{ 'active': isActive, 'error': isError, 'disabled': isDisabled && !isError }"> <h3>Vue Class Binding Multiple Condition</h3> <p>Click the buttons below to toggle the classes:</p> <button @click="isActive = !isActive">Toggle Active</button> <button @click="isError = !isError">Toggle Error</button> <button @click="isDisabled = !isDisabled">Toggle Disabled</button> </div> </div> <script type="module"> const app = new Vue({ el: "#app", data() { return { isActive: false, isError: false, isDisabled: false, }; }, }); </script> <style> .container { padding: 20px; } .active { background-color: lightblue; } .error { color: red; } .disabled { opacity: 0.5; cursor: not-allowed; } </style>Output of Vue Class Binding Multiple Condition
