I make a program. Use price and category to query the data in the database. Look at the picture below.
These two queries are optional. In other words, the user can select or not select these two options to query. I use radioGroup to check prices. Use checkboxGroup to query category. I found that when using radioGroup, I can check whether its value is empty to determine whether it is selected by the user. The statement is very simple.
if ($w(“#radioGroup1”).value === “” )
But this method does not work for checkboxGroup. I used 3 statements below
if ($w(“#checkboxGroup1”).value === “”)
if ($w(“#checkboxGroup1”).value === )
if ($w(“#checkboxGroup1”).value === null )
but them didn’t work. see the image below. My question is in programming, how to detect whether the checkboxGroup is selected ? Hope to get help.
