JS (ii) numeric objects and string objects

First, JS function

Because there are more things to learn, easy to confuse. Also can not be remembered, here notes, later to use the time, will be able to quickly recall.

Index-number.js

/** * Display Digital Object */function myFunction () {var x1 = 3.14;//decimal var x2 = 11;//integer var x3 = 14e5;//large number var x4 = 0237;//octal var x5 = 0x12f;//hex var y = 0.1 + 0.2;var str = "x1:" + x1 + "<br/>x2:" + x2 + "<br/>x3:" + x3 + "<BR/>X4:" + x4+ "<br/>x5:" + x5;document.write (str + "<br/>");d ocument.write (y);} /** * Display String Object */function MyFunction2 () {var str= "<p> This is the text content of the JS object </p>"; var str2= "Black"; var str3= " This is the text content of the JS object "document.write (Str.italics ());//The text is Italic document.write (Str.fontcolor (" #ff0000 "));//The text color is red, Note the case document.write (Str.link ("http://www.baidu.com"));//Click on the link of the content Jump document.write (Str.bold ());// The text is in bold document.write (Str2.tolocalelowercase ());//Lowercase document.write (str2.touppercase ());//Uppercase document.write ( Str.fontcolor ("Red"). FontSize (20));//change both the text color and the font size document.write (str3.fontsize (+) + str2.sub () +str3.fontsize (20 ) +str2.sup ());//superscript and subscript document.write (str.replace ("JS", "JavaScript");//Replace}
