Simple example of JS implementation inserting content at a text specified location

Examples are as follows:

function insertAtCursor(myField, myValue) { 
 
 //IE browser if () { 
  (); 
  sel = (); 
   = myValue; 
  (); 
 } 
 
 //FireFox, Chrome, etc. else if ( ||  == '0') { 
  var startPos = ; 
  var endPos = ; 
 
  // Save the scrollbar  var restoreTop = ; 
   = (0, startPos) + myValue + (endPos, ); 
  
  if (restoreTop &gt; 0) { 
   = restoreTop; 
  } 
  
  (); 
   = startPos + ; 
   = startPos + ; 
 } else { 
   += myValue; 
  (); 
 } 
} 
&lt;textarea  style="width: 386px; height: 260px"&gt; 
&lt;/textarea&gt; 
&lt;input type="text"  /&gt; 
&lt;input type="button" value="insert" onclick="insertAtCursor(('textarea'),('text').value)" /&gt;

The above simple example of inserting content in the specified location of the text by JS is all the content I share with you. I hope you can give you a reference and I hope you can support me more.
