AcroDialog : how to select the value of a field ?

I would like to use an AcroDialog window for updating a field in a PDF form and I need to populate an "edit text" with  the value of the field "Text1" existing in the form. How the following script must be modified to do so ?

Probably very simple... but I stumble on the solution.

Many thanks in advance for your advices

var oJSDlg = {
strEdt1:null,

},
validate:function(dialog){
  var bRtn = true;

  return bRtn;
},
commit:function(dialog){
  var oRslt = dialog.store();
  this.strEdt1 = oRslt.Edt1;
},

}
}

if("ok"==app.execDialog(oJSDlg))
{
console.println("strEdt1 = "+oJSDlg.strEdt1);
}

This is something I'll be changing in the AcroDialog tool. The problem is that you didn't define a default value for "Edt1", so there is no initialization for this edit box.  To fix this you can go back to AcroDialogs and add an "initial value" to "Edt1" and recreate the dialog.  You might also consider changing the variable name to something that makes sense for the value. And also the "item_id". And also the dialog object variable name. But these are not necessary, it just makes the code easier to read.

You'll get Something that looks like this

var oJSDlg = {
strEdt1:"My Value",
initialize:function(dialog){
    dialog.load({"Edt1":this.strEdt});
},
... Rest of dialog code...

Then for using the dialog do this

oJSDlg.strEdt1 = this.getField("Text1").value;
if("ok"==app.execDialog(oJSDlg))
{
    this.getField("TExt1").value = oJSDlg.strMyTest;
}

You can also just make these changes on your existing code. It's a good exercise to get you more familiar with dialog object scripting

Thank you very much, Thom : that works exactly how I expected !

I've just modified typos (in case other readers are interested in the subject )

And I will take into account your advice for the readability of the code.

var oJSDlg = { 

strEdt1:"My Value", 

initialize:function(dialog){ 

    dialog.load({"Edt1":this.strEdt1}); 

}, 

oJSDlg.strEdt1 = this.getField("Text1").value; 

if("ok"==app.execDialog(oJSDlg)) 

{ 

this.getField("Text1").value = oJSDlg.strEdt1; 

}
