var sToChange = “The sky is red.”;
var reRed = /red/;
var sResultText = sToChange.replace(reRed, function(sMatch) {
return “blue”;
});
sMatch 指的是被匹配到到的对象, return 返回替换的对象
var reBadWords = /badword|anotherbadword/gi;
var sUserInput = “This is a string using badword1 and badword2.”;
var sFinalText = sUserInput.replace(reBadWords, function(sMatch) {
return sMatch.replace(/./g, “*”);
});
alert(sFinalText); //output “This is a string using ******* and **************”
屏蔽关键字

var reTag = /<(?:.|\s)*?>/g;
return this.replace(reTag, “”);
