PDF Form javascript for making readonly field by using button

[Guest]

Please let me know the PDF Form JavaScript for making selected fields(Text field,Drop down list,..) as read-only by using Button.

[try67]

this.getField("FieldNameHere").readonly = true;

[Guest]

Thanks Mr.Gilad D, its working fine.

I know this an old post, but I was wondering if there was an all fields command for this? I used that line effectively to lock one field, but can I change the field name to something that does all of the fields? Thank you!

‌Create a loop over all fields.

[jayk70698836]

Can you please explain how to do this? I have searched creating a loop and I have found a few different articles but I can't find the proper code to insert into the javascript box that comes up with the button.

Do you want your button to be made read only?

One starts with Acrobat JS Reference.

// make all fields in a form read only;

var oField; // variable for field being processed;

// loop through the form fields;

for (var i = 0; i < this.numFields; i++) {

// process each field name;

oField = this.getField(this.getNthFieldName(i)).readonly = true;

}

That works perfectly! Thank you very much.

Is it possible to use the script below for more fields in a form?

this.getField("FieldNameHere").readonly = true;

For example:

My form have the following fields:

Fieldname-1, Fieldname-2, Fieldname-3, Fieldname-4, Fieldname-5 and Fieldname-6.

Fieldname-1 thru Field-name-4 must be read-on with the javascript. How most i change the script?

Kind regards,

Jarno

You can use following:

for (var i = 1; i <= 6; i++) {

  this.getField("Fieldname-" + i).readonly = true;

}

So thankful for this...

Is there also a possibility to "reverse" this action?

I used this snippet:

// make all fields in a form read only;

var oField; // variable for field being processed;

// loop through the form fields;

for (var i = 0; i < this.numFields; i++) {

// process each field name;

oField = this.getField(this.getNthFieldName(i)).readonly = true;

}

and it works great, but I would like to add another button to the document, to undo the first snippet. (For my clients, in case he presses the first button and saves the document by default... )

Thank you all in advance, best regards, Sanny

[try67]

Use the same code, replacing "readonly = true" with "readonly = false" ...

Hey try67,

thanks for your fast reply, so great.

I wanted to try it, but after using the button with the first snippet`s JS, it seems that the "buttons" aren´t buttons anymore. So the "redo" Button isn`t working at all, on click both buttons only switch between normal and hover-style. Guess i will have to make sure, that buttons shall NOT be changed in the first snippet. With other words: Put an exception for special fields.(by name/function) or other way round, ONLY TEXTfields shall be read only, but nothing else)

Maybe you have a solution for this, too? (I`m sorry, got no idea about JS)

Thanks in advance.

[try67]

Yeah, that makes sense... Should have thought of that before.

And yes, of course you can do it. Here's how you ignore specific fields:

for (var i = 0; i < this.numFields; i++) {

var fname = this.getNthFieldName(i);

if (fname!="Button1" && fname!="Button2") {

     this.getField(fname).readonly = true;

}

}

[SannyFuchs]

Wohooha, this works! Thank you so much!

Just one thing in addition, maybe its useful for someone else:

I found this snippet, which includes an "alarmfield":

var r = app.alert("Are you sure to do this?",2,2);

if (r == 4) { // 4 is Yes, 3 is No

    for (var i = 0; i < this.numFields; i++) {

        var fname = this.getNthFieldName(i);

        this.getField(fname).readonly = true; // makes all fields readonly

    }

}

and combined it with your last one, excluding the buttons.

var r = app.alert("Are you sure to do this?",2,2);

if (r == 4) { // 4 is Yes, 3 is No

for (var i = 0; i < this.numFields; i++) {

var fname = this.getNthFieldName(i);

if (fname!="Button1" && fname!="Button2") {

     this.getField(fname).readonly = true;

}}

}

It works! Maybe I should learn JS... ^^  Thank you very much, Try67!

My script for Java isn't working for about 100+ fields and is frustrating me! The first field only works as it converts to ReadOnly but the rest don't.

Can someone please tell me what I'm doing wrong?

I'm using this:

var
svfile = app.alert ("You are about to lock the fields. You will not be
able to update your info after the fields are locked. Lock fields?", 1,
1);

if
(svfile == 2 || svfile ==3) {

     app.alert ("Please review your data
and return to this button to lock fields.", 1);

     };

if (svfile == 4 || svfile ==1) {

   
this.getField("JobTitle").readonly = true;
this.getField("JobTitle1").readonly = true;

this.getField("JobLevel").readonly = true;

this.getField("Check Box18").readonly = true;

this.getField("Check Box19").readonly = true;

this.getField("Check Box20").readonly = true;

};

[try67]

Did you create child fields like "JobTitle.1", "JobTitle.2", etc.? If not, why would it edit 100 fields if you only run it on six?

[Guest]

I have over 100 fields and checkboxes with different names but I only pasted 6 for demonstration.

[try67]

So what is not working correctly, then?

[Guest]

I copied and pasted my code to Word incase my PDF freezes. Basically, I pasted the exact script in the Javascipt action and only certain fields are converted to Read-Only while a majority of them are not. I checked over the field and check-boxes names and they were correct.

I'm not sure why this is happening. When I physically type out 20+ field name in the script coding area, it works. Typing out over 100 will take quite a long time.

[try67]

Do you want to set all the fields in the file as read-only?

[Guest]

Yes! I need to set all the fields to Read only upon a prompt message.

Except all the fields, checkboxes, drop-downs are named variously!

I would appreciate a solution!

[Guest]

It's not absolutely necessary to have a prompt message but I do need to create a button that allows users that option

[try67]

You can use this code, either with your alert or without it:

for (var i=0; i<this.numFields; i++) {
    var f = this.getField(this.getNthFieldName(i));
    if (f==null) continue;
    f.readonly = true;
}

[Guest]

This code works perfectly thank! How can I add this with the prompt message?

Would it be this:

var
svfile = app.alert ("You are about to lock the fields. You will not be
able to update your info after the fields are locked. Lock fields?", 1,
1);

if
(svfile == 2 || svfile ==3) {

     app.alert ("Please review your data
and return to this button to lock fields.", 1);

     };

{  

for (var i=0; i<this.numFields; i++) {
    var f = this.getField(this.getNthFieldName(i));
    if (f==null) continue;
    f.readonly = true;
}
