Insert special character in value

I have a panel form in ExtJS and a textfield inside and I am trying to insert a . symbol before * in this textfield. I have a button that sends the value from this textfield to a server and returns me results.

In my code, I check if a string contains a * symbol, then I insert the . from this textfield into it.

Example of what I have now: I type in textfield *test* my code convert it to *test.*. What I need is .*test.*.

If I type in textfield *t*st* I need the .*t.*st.* as a result.

How I can insert the . symbol before every * symbol in my value string?

fieldLabel: 'name',
name: 'name',
submitValue: true,
enableKeyEvents: true,      
  getSubmitValue: function () {
   var value = this.getValue();
   var format = /[*]+/; 
   let valTrimmed = value.slice(0, value.length -1); 
   var ts = '';
     if(format.test(value)){
     ts = valTrimmed + '.*';
     return ts;
 }              
  return value; 
}

It appears you can simply replace each * with itself and a . in front using

getSubmitValue: function () { 
  return this.getValue().replace(/\*/g, '.$&'); 
}

Note that /\*/g regex matches all occurrences of * (escaped, since it is a special regex metacharacter) and the $& in the replacement pattern refers to the whole match.
