Want JS Form Field Name to Disappear when clicking into text field

I followed the instructions on this thread: https://community.adobe.com/t5/acrobat-discussions/pdf-text-field-form-label/m-p/3137258#M7006 where George_Johnson gave great info on how to get form fields to display the tooltip value by default. 

 

I am using this JS on a free text field:

 

if (!event.value) {

event.value = event.target.userName;

}

 

In it's default state (Tool Tip populating inside the text field), it is showing properly, printing properly, and saving properly.  What I please need help with is this: I want the text to disappear when the user clicks into the field to enter their own custom text.  Currently, when you click into the field, the text remains and you have to select it/delete it before typing.  Is this possible?

 

THANK YOU

I just cannot get this to work.  Using your suggested code:

if (event.target.value=="") event.target.value = event.target.defaultValue;

 

And an onptional "default value":

 

 

 

I see this (good):

But when i click into it, it doesn't clear.  The default value remains and I have to delete it all manually before entering what I want. 

 

 

 


Use the On Blur event.

As the field's On Focus event enter this code:

event.target.value = "";

Keep in mind, though, that this code will also clear any input the user enters into the field, which you might not want to do... To avoid that you can change it to the following:

 

if (event.target.value == event.target.userName)  event.target.value = "";

Thank you!  Getting closer!  If I click into the field, the default text dissappears.  However, if I click out of it (without entering anything) the original text does not return.  Is this possible?


Stated another way, if the entry is Null, I want the Tool Tip name to appear in the field. If the cursor is active in the box, or if the user has entered any text, I want the tool tip name to be gone.
