@ is a shortcut option for v-on. Use @ only when you want to execute some Vue methods. As you are not executing Vue methods, instead you are calling javascript function, you need to use onchange attribute to call javascript function
<select name="LeaveType" onchange="onChange(this.value)" class="form-control">
<option value="1">Annual Leave/ Off-Day</option>
<option value="2">On Demand Leave</option>
</select>
function onChange(value) {
console.log(value);
}
If you want to call Vue methods, do it like this-
<select name="LeaveType" @change="onChange($event)" class="form-control">
<option value="1">Annual Leave/ Off-Day</option>
<option value="2">On Demand Leave</option>
</select>
new Vue({
...
...
methods:{
onChange:function(event){
console.log(event.target.value);
}
}
})
You can use v-model data attribute on the select element to bind the value.
<select v-model="selectedValue" name="LeaveType" onchange="onChange(this.value)" class="form-control">
<option value="1">Annual Leave/ Off-Day</option>
<option value="2">On Demand Leave</option>
</select>
new Vue({
data:{
selectedValue : 1, // First option will be selected by default
},
...
...
methods:{
onChange:function(event){
console.log(this.selectedValue);
}
}
})
Hope this Helps :-)
