I use Vue js conditional statements in multiple elements.
In some cases, i need to place if and else in same element to filter the elements.
Here,i use multiple elements to apply if and else.
<block v-if="nb == 3" align="left"></block>
<block v-if="nb > 3" align="center"></block>
But i want to apply both in single element like,
<block v-if="nb == 3" align="left" v-else align="center"></block>
Is it possible ?
Or Any other solution to apply this ?
Thank in advance.
Rather than using v-if, try binding the attribute to a ternary expression.
// : is a shorthand for v-bind:
<block :align="nb == 3 ? 'left' : 'center'"></block>
If that looks a little too messy for you (or if the logic you want to use is too complicated to express in a single line), you could also try creating a computed property in your component that returns "left" or "center", and then bind to that instead.
v-if and v-else on the same element, so I think binding to something is the only way.
v-if and v-else is for an entire element and not for an attribute, so this ternary seems like the bast way.v-if/else, it'd make your markup more cluttered than it needs to be.You can't use v-if and v-else on the same element.
I'd personally use a computed property.
I'm assuming your nb is a reactive variable or similar.
Therefore you should be looking for something like this:
<block v-bind:align="computedAlign"></block>
and then in your component
// assuming you're using data and not props
data() {
return {
nb: 1 // default
}
},
// some other stuff that sets the nb variable in some way
computed: {
computedAlign() => {
if (this.nb === 3) {
return 'left'
} else {
return 'center'
}
}
}
You could simply achieve that with a ternary operator
<block :align="nb==3?'right':'left'"></block>
