The example in this article describes the method of dynamically displaying text in the status bar using JavaScript. Share it with everyone for your reference, the details are as follows:

<script>
 var child = window.open("information.html","_blank","width=200,height=200,toolbar=no");
 function closeChild(){
 if(!child.closed){
  child.close();
 }
 }
 //设置间隔1秒钟，调用一次scroll()
 setInterval("scroll()",100)
 var space_num = 0;
 var dir = 1; //文本开始从左向右移动
 function scroll(){
 var str_space = "";
 space_num = space_num + 1*dir;
 //如果空格数大于40 或者 小于0时
 if(space_num > 40 || space_num <= 0){
  dir = dir * (-1);
 }
 //空格数自增
 for(var i=0; i<space_num; i++){
  str_space += " ";
 }
 //在文字前空格数变换
 window.status = str_space + "welcome to study";
 }
</script>
<body onunload="closeChild()">
</body>
