The examples in this article describe js string operation methods. Share it with everyone for your reference. The details are as follows:

var str="This is my first Script code.";
document.write("原字符串为："+str+"<br>")
document.write("第五个字符之后的部分："+str.slice(5,-1)+"<br>");
document.write("第五个字符之后的15个字符："+str.substr(5,15)+"<br>");
document.write("第五个字符后至第15个字符："+str.substring(5,15)+"<br>");
