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>
I hope this article will be helpful to everyone in JavaScript programming.
