Execute a JavaScript when a user writes something in an <input> field

[CintiaC]

Hi, I need a js code for acrobate pro dc to display next action only when the user writes something in text field.

Thanks

Maybe:

var xx=this.getField("xx");

If (xx.value != "") {your code}

run this script on focus off event

As the custom validation script of the field use this:

if (event.value) {

// place your code here

}

This code work perfectly but it´s possible to display the next action for example after 10 characters? right now the action is displayed when they write and click out of the text field.

To do that you would need to use the Keystroke event. It's possible, but more complicated. And you need to provide a more detailed description of how you want it to work...

Thanks once again for all the help that you provide! I will keep the code as your above suggestion, if the user must click outside the frame so be it, tx!

I have a similar action in my pdf. It counts points from checkboxes.

You can check how many characters have been entered.

Maybe it will help you.

the given solution will probably not be useful to you. requires confirmation (enter) or clicking outside the frame 😞

Thanks a lot for your help regarding this issue, I think I will keep it simple and let the user click outside the frame to run the next action, tx for your suggestion!

script in mouse exit event.

if (this.getField("xx").value.length >= 1) { app.alert("out: " + this.getField("xx").value + " :-)"); }

to display the current value, unfortunately you have to confirm the entry with the "enter" key. then you just need to move the mouse outside the frame and the script will run

[Krzysztof_OciecG]

Caution.
the Mouse Exit event is sensitive to mouse movement; if the frame is small, it is easy with the mouse cursor to accidentally move out of the frame, which will run the script

[Krzysztof_OciecG]

look hier:

and script:

if (event.willCommit) {
/*
app.alert(":-)");
*/

this.resetForm([event.target.name]); // Reset field to lose focus

this.getField("YourNextField").value = event.value;

}

[Krzysztof_OciecG]

Od course, any your script can follow the event.willcommit

for a joke: mouse exit event changes the string: test ONE / test TWO, and each character entered increases the frame "NextTabField". Space resets its dimensions to the initial 😉

this time the construcion if(even.value) {...} was used in the custom Format field

really nice feedback and option Krzysztof 🙂 tx a lote
