Can I set the eform that let adobe reader not highlight the field?

It is possible with JavaScript to control whether field highlighting is active, but it's considered bad form to alter a user's preference setting without letting them know or at least attempting to restore the settings when the controlling document closed. Here is some code you can use in a document-level JavaScript that executes when the document is opened:

var bRTH = app.runtimeHighlight;  // Store the current field highlighting setting

app.runtimeHighlight = false;  // Turn off field highlighting

Then, in the Document Will Close event, you can restore the setting to the original:

// Restore the field highlighting setting

app.runtimeHighlight = bRTH;
