"Having trouble with a single line conditional statement not functioning properly within data in a Vue

I am facing an issue with setting the data named isVendorOrAgent in a component. It should be either false or

true> based on a property that the component receives. I noticed that when I tried setting this condition within the data section of the component, it always returns <code>false

. However, when I moved the logic to the created() hook and set isVendorOrAgent there, it worked as expected.

How can I resolve this? Any suggestions?

The initial non-working approach is shown below:

data: () => {
   return {
      isVendorOrAgent: (this.entityName == "vendor" || this.entityName == "agent") ? true : false;
   }
}

However, things start working by defaulting to false using the following working approach:

created() {
    if(this.entityName == "vendor" || this.entityName == "agent"){
      this.isVendorOrAgent = true;
    }
  }

Answer №1

Here is a suggested code snippet to help with your issue:

data () {
  return {
    isVendorOrAgent: Boolean(this.entityName === "vendor" || this.entityName === "agent")
  }
}

What sets this apart?

The data function is not written as an arrow function, ensuring the correct context for this within the component
We have introduced using a Boolean value
We are now utilizing strict equality ===, which is considered a best practice

You may also want to explore computed properties: https://v2.vuejs.org/v2/guide/computed.html

To address your problem in another way:

computed () {
  return {
    isVendorOrAgent: Boolean(this.entityName === "vendor" || this.entityName === "agent")
  }
}

The second method is recommended if you require reactivity in this property.
