Fill a text field from dtaa in a drop down menu

You can use this script in the dropdown field as a Validate script:

var cList = {
 "Client Name1": { accountNum: 123, orderNum: 111 },
 "Client Name2": { accountNum: 234, orderNum: 222 },
 "Client Name3": { accountNum: 345, orderNum: 333 }
};

var f1 = this.getField("Text1");
var f2 = this.getField("Text2");
var f3 = this.getField("Text3");
var selectedName = event.value;

if (cList[selectedName]) {
 f1.value = selectedName;
 f2.value = cList[selectedName].accountNum;
 f3.value = cList[selectedName].orderNum;} 
else {
 f1.value = "";
 f2.value = "";
 f3.value = "";}

Replace "Text1", "Text2", and "Text3" with the actual field names in your form.

Replace "Client Name1", "Client Name2", etc., with the names that appear in your dropdown field.

Update the accountNum and orderNum values with the correct numbers for each client.

If you add more clients, simply add a new line inside cList, using a comma after each entry (except the last one).

As the custom validation event of the drop-down field enter code like this:

if (event.value=="John Smith") {
	this.getField("Text field 1").value = "12345";
	this.getField("Text field 2").value = "99999";
	this.getField("Text field 3").value = event.value;
} else if (event.value=="Jane Doe") {{
	this.getField("Text field 1").value = "23456";
	this.getField("Text field 2").value = "88888";
	this.getField("Text field 3").value = event.value;
}
//etc.
else {
	this.getField("Text field 1").value = "";
	this.getField("Text field 2").value = "";
	this.getField("Text field 3").value = "";
}

Adjust the field names and values as needed, of course.

you have other posts in the acrobat forum, so i'm not sure why you posted in a forum that for discussions about adobe's forums.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
