Use js to get the focus at the end of the text box and the focus at the end of the js text box

Use js to get the focus at the end of the text box and the focus at the end of the js text box

function moveEnd(obj) {obj.focus();var len = obj.value.length;if (document.selection) {var sel = obj.createTextRange();sel.moveStart('character', len);sel.collapse();sel.select();} else if (typeof obj.selectionStart == 'number'&& typeof obj.selectionEnd == 'number') {obj.selectionStart = obj.selectionEnd = len;}}

How can I jump the cursor position to the end of the text box in JS to get the focus?

<Script language = "javascript">
Function setFocus ()
{
Var obj = event. srcElement;
Var txt = obj. createTextRange ();
Txt. moveStart ('character ', obj. value. length );
Txt. collapse (true );
Txt. select ();
}
</Script>
<Input type = "text" value = "abcdefg123456789" onfocus = "setFocus ()">

How can I jump the cursor position to the end of the text box after JS focus () is obtained?

<Input type = "text" id = "test1" name = "test1" value = "test123" onclick = "moveEnd (this);"/>

Obj. focus ();
Var len = obj. value. length;
If (document. selection ){
Var sel = obj. createTextRange ();
Sel. moveStart ('character ', len );
Sel. collapse ();
Sel. select ();
} Else if (typeof obj. selectionStart = 'number'
& Typeof obj. selectionEnd = 'number '){
Obj. selectionStart = obj. selectionEnd = len;
}
}
