asking if a javascript can be written to unhide and select a field based on a selection from a dropdown list?

This topic has been closed for replies.
Correct answer try67

I used the following code:

Var otherField = this.getField(“2nd Lock Template”);

If (event.value==”Other (Complete Below)” {

otherField.readonly = false

otherField.setFocus();}

else

otherField.readonly = true

otherField.value = “”;}

Is there any way I can keep “2nd Lock Template” hidden and unhide in this code?

Thanks

Tom


Yes, by using this code:

var otherField = this.getField("2nd Lock Template"); 
if (event.value=="Other (Complete Below)") { 
    otherField.display = display.visible;
    otherField.readonly = false; 
    otherField.setFocus(); 
} else { 
    otherField.display = display.hidden;
    otherField.readonly = true; 
    otherField.value = ""; 
}

By the way, I noticed that in your code there are various problems. Do not use Word for editing code! Only use a plain-text editor, like Notepad.

JavaScript can "unhide" a field, yes, but I'm not sure what you mean by "select" it... Please clarify.

I have several dropdown lists on my form, for some of the selections I would like to have another field unhide so the operator can type in some information. However most of the answers do not require operator information so I don’t want the hidden field to show if those answers are selected.

So the visibility of this field should be dependent on the value of multiple fields? That's a bit tricky... Under what circumstances should the field be visible then?


The list will contain standard choices, but one choice will be “Other”. If that choice is selected then I want the control to go to another text field that the operator can type in their answer. So for instance there will be 5 standard choices and one that is “Other”. When a standard choice is selected we’ll go to the next item, when “Other” is selected we’ll unhide a text field and send control there.
