Common methods for JavaScript string objects Concise version _ Basics

var a = "abcdefggdefg32asdf38";
document.write ("Original:" +a+ "<br/>") document.write ("Bold:" +a.bold () + "<br/>");
document.write ("Large:" +a.big () + "<br/>");
document.write ("Italic:" +a.italics () + "<br/>");
document.write ("Delete line:" +a.strike () + "<br/>");
document.write ("Font size:" +a.fontsize + "<br/>");
document.write ("Font color:" +a.fontcolor ("#ff0000") + "<br/>");
document.write ("Superscript:" +a.sup () + "<br/>");
document.write ("Subscript:" +a.sub () + "<br/>");
document.write ("Uppercase:" +a.touppercase () + "<br/>");
document.write ("Uppercase:" +a.tolowercase () + "<br/>"); document.write ("Return index character:" +a.charat (3) + "<br/>");//This should be "D" document.write ("return Index:" +a.indexof ("F") + "&LT;BR/ > ")//This should be 5 document.write (" Return index (reverse lookup): "+a.lastindexof (" F ") +" <br/> ");//This should be 9 document.write (" Find string: "+ A.search ("F") + "<br/>");//This should be 5, same as IndexOf document.write ("Replacement string:" +a.replace ("a", "a") + "<br/>"); Replace a in the string with a document.write ("Return substring:" +a.slice (1,3) + "<br/>");/BC, return from index 1 to 3-1Substring document.write ("Split string:" +a.split ("D"). ToString () + "<br/>");//D as a separator, split string, return array document.write ("Return substring:" + A.SUBSTR (1,2) + "<br/>")//return substring, starting with index 1, length 2, this is BC document.write ("Return substring:" +a.substring (1,3) + "<br/>"); /Same as Sclice (), return substring of index 1 to 3-1 ("match:" +a.match (/\d+/) + "<br/>");//Regular match, return matching result, here is 32
