Toggle Presence else if statement

[Former Community Member]

Hi Guys,

Im trying to make a button which will show/hide a 'BankDetails' subform when clicked.

When I click the button, it hides the subform and changes the button text to 'Show' (working correctly) but when I click it again it does nothing.... it isnt seeing the 'else if' statement.

I'm new to scripting so any help would be greatly appreciated!

 form1.BankDetails_Title.Table1.HeaderRow.Button2::mouseUp - (JavaScript, client)
if(this.parent.parent.parent.parent.BankDetails.presence = "visible")
    {
        this.parent.parent.parent.parent.BankDetails.presence = "hidden"; 
        this.resolveNode("caption.value.#text").value = "Show";
    }
else if(    this.parent.parent.parent.parent.BankDetails.presence = "hidden")
    {
        this.parent.parent.parent.parent.BankDetails.presence = "visible"; 
        this.resolveNode("caption.value.#text").value = "Hide";
    }

if there are only 2 possible states (ie. visible or hidden) then you don't need an 'else if' just an 'else' statement.

Thanks whyisthisme,

I did try to use the else statement instead but had no luck...

form1.BankDetails_Title.Table1.HeaderRow.Button2::mouseUp - (JavaScript, client)
if(this.parent.parent.parent.parent.BankDetails.presence = "hidden"){
      this.parent.parent.parent.parent.BankDetails.presence = "visible";
      this.resolveNode("caption.value.#text").value = "Hide";
}
     else {
           this.parent.parent.parent.parent.BankDetails.presence = "hidden";
           this.resolveNode("caption.value.#text").value = "Show";
}

It works when I initially click the button (will show the hidden subform) but when i click it the second time it does not hide the subform again.

You have to use an equality operator '==' in your if statement when comparing two values. The equality operator compares the left and right operands' values and returns a boolean (true or false). You are using an assignment operator '=', which takes the right side operand and assigns its value to the left and returns that value.

So if your using '=' in your if statement then you would normally be assigning strings or positive numbers which when evaluated, will always return true (such as in your case).

Thanks Kyle!

worked perfectly!

I used:

if(	this.parent.parent.parent.parent.BankDetails.presence == "hidden"

Thanks again!
