Prevent textarea from automatically scrolling when I change cursor position


Prevent textarea from automatically scrolling when I change cursor position

To fix this issue I have a textarea with a lot of text and a vertical scrollbar. When I move the cursor beyond the visible area (imagine having a long document, and then pressing down arrow many times until cursor goes off screen), the browser will automatically scroll the cursor into view, so it always remains visible. , It doesn't appear this is possible. From the spec:

Hope this helps "Changes position automatically" is android reusing views. I think the problem is in your adapter. Even if you check whether view is null or not, you still need to set the TextView ids.
code :
  if(convertView == null){
        convertView=inflater.inflate(R.layout.grid_item, null);
  }

   txtFirst=(TextView) convertView.findViewById(R.id.item1);
   txtSecond=(TextView) convertView.findViewById(R.id.item2);
   txtThird=(TextView) convertView.findViewById(R.id.item3);
   txtFourth=(TextView) convertView.findViewById(R.id.item4);
   txtFifth = (TextView) convertView.findViewById(R.id.item5);

hope this fix your issue You have to change the cursor position after the state has been updated(setState() does not immediately mutate this.state)
In order to do that, you have to wrap this.refs.input.selectionStart = this.refs.input.selectionEnd = start + 1; in a function and pass it as the second argument to setState (callback).
code :
handleKeyDown(event) {
      if (event.keyCode === 9) { // tab was pressed
          event.preventDefault();
          var val = this.state.scriptString,
          start = event.target.selectionStart,
          end = event.target.selectionEnd;
          this.setState(
              {
                  "scriptString": val.substring(0, start) + '\t' + val.substring(end)
              },
              () => {
                  this.refs.input.selectionStart = this.refs.input.selectionEnd = start + 1
              });
      }
 }

I hope this helps . check the first character on keyup, if it's Arabic add this direction: rtl;
code :
var la_ar = 
["ي","و","ه","ش","س","ق","ف","غ","ع","ض","ص","ن","م","ل","ك","ظ","ط","ز","ر","ذ","د","خ","ح","ج","ث","ت","ب","ا"]
$("input").keyup(function(){
var la_ar = 
["ي","و","ه","ش","س","ق","ف","غ","ع","ض","ص","ن","م","ل","ك","ظ","ط","ز","ر","ذ","د","خ","ح","ج","ث","ت","ب","ا"]
    var bla = $(this).val();
    var blaـl = bla.charAt(0);
    if($.inArray(blaـl, la_ar) > -1 ){
      //alert('in');
      $(this).css("direction","rtl");


    }else{
      //alert('out');
      $(this).css("direction","ltr");
    }
});
