JavaScript method to achieve typing effect_javascript skills

The example in this article describes how JavaScript can achieve typing effects. Share it with everyone for your reference. The specific implementation method is as follows:

<input type="button" onclick='start("高考了")' value="start"/>
<input type="text" id="here" />
<script type="text/javascript">
function start(str1)
{
str=str1;
len=str.length;
i=0;
dwrite();
}
function dwrite()
{
  document.getElementById('here').value=document.getElementById('here').value + str.charAt(i);
  if( i++ ==len )
  {
   i=0;
   return true;
  }
  setTimeout('dwrite()',500);
}
</script>

I hope this article will be helpful to everyone’s JavaScript programming design.
