I would expect that setting the disabled attribute on a react component would block the onClick handler for that element.
<a role="button"
className={`btn btn-block btn-info`}
disabled={!this.state.readyToView}
href={this.state.selectedObjectLink}
onClick={this.handleLink}
>View</a>
but although the element shows a "disabled" attribute it still registers a click event.
Edit: I should clarify - I handle the click event in handleLink, I want to know why the disabled attribute doesn't remove the handler? Sorry for any confusion.
The problem isn't with disabled; it's with the HTML element a. Anchor <a> cannot have a disabled property (what does that even mean?). Just because you've passed CSS to make the element look like a button, doesn't make it a button. It is still an anchor.
The solution would be either to use something else (like button):
<button
role="button"
className={`btn btn-block btn-info`}
disabled={!this.state.readyToView}
onClick={this.handleLink}
>
View
</button>
You can use this.state.selectedObjectLink inside handleLink if you want to redirect to a page
Or use one of the many other suggestions on this page.
Why not just handle this in handleLink?
handleLink () {
if (!this.state.readyToView) return
// ...
}
If you really want to bind/remove the handler dynamically, you can do something like this:
const clickHandler = this.state.readyToView ? this.handleLink : null
...
<a role="button"
...
...
onClick={clickHandler}
>View</a>
