Are complex expressions possible in ng-hide / ng-show?

Question

I want to do so:

ng-hide=\"!globals.isAdmin && mapping.is_default\"

but the expression evaluates always to false.

Answer 1

I generally try to avoid expressions with ng-show and ng-hide as they were designed as booleans, not conditionals. If I need both conditional and boolean logic, I prefer to put in the conditional logic using ng-if as the first check, then add in an additional check for the boolean logic with ng-show and ng-hide

Howerver, if you want to use a conditional for ng-show or ng-hide, here is a link with some examples: Conditional Display using ng-if, ng-show, ng-hide, ng-include, ng-switch

Answer 2

Some of these above answers didn't work for me but this did. Just in case someone else has the same issue.

ng-show="column != 'vendorid' && column !='billingMonth'"

Answer 3

Use a controller method if you need to run arbitrary JavaScript code, or you could define a filter that returned true or false.

I just tested (should have done that first), and something like ng-show="!a && b" worked as expected.

Answer 4

ng-show / ng-hide accepts only boolean values.

For complex expressions it is good to use controller and scope to avoid complications.

Below one will work (It is not very complex expression)

ng-show="User=='admin' || User=='teacher'"

Here element will be shown in UI when any of the two condition return true (OR operation).

Like this you can use any expressions.

Answer 5

This will work if you do not have too many expressions.

Example: ng-show="form.type === 'Limited Company' || form.type === 'Limited Partnership'"

For any more expressions than this use a controller.
