</div>
</div>

It’s hard to judge your problem without seeing the CSS in question. My suspicion is that removing
showisn’t enough to hide the element unless you have another class applying some kind ofhideclass. See the simplified example:you can do like this
You can remove show class like this
And if you want to remove show when request done use "then" property of axios or fetch
or use finally
#You must define spinner as classname at this situation
