格式化字串
<script language=”JavaScript”>
<!--
var myVariable = “Hello there”;
document.write(myVariable.big() + “<br>”);
document.write(myVariable.blink() + “<br>”);
document.write(myVariable.bold() + “<br>”);
document.write(myVariable.fixed() + “<br>”);
document.write(myVariable.fontcolor(“red”) + “<br>”);
document.write(myVariable.fontsize(“18pt”) + “<br>”);
document.write(myVariable.italics() + “<br>”);
document.write(myVariable.small() + “<br>”);
document.write(myVariable.strike() + “<br>”);
document.write(myVariable.sub() + “<br>”);
document.write(myVariable.sup() + “<br>”);
document.write(myVariable.toLowerCase() + “<br>”);
document.write(myVariable.toUpperCase() + “<br>”);
var firstString = “My String”;
var finalString = firstString.bold().toLowerCase().fontcolor(“red”);
// -->
</script>
创建数组
<script language=”JavaScript”>
<!--
var myArray = new Array(5);
myArray[0] = “First Entry”;
myArray[1] = “Second Entry”;
myArray[2] = “Third Entry”;
myArray[3] = “Fourth Entry”;
myArray[4] = “Fifth Entry”;
var anotherArray = new Array(“First Entry”,”Second Entry”,”Third Entry”,”Fourth Entry”,”Fifth Entry”);
// -->
</script>
数组排序
<script language=”JavaScript”>
<!--
var myArray = new Array(5);
myArray[0] = “z”;
myArray[1] = “c”;
myArray[2] = “d”;
myArray[3] = “a”;
myArray[4] = “q”;
document.write(myArray.sort());
// -->
</script>
分割字符串
<script language=”JavaScript”>
<!--
var myVariable = “a,b,c,d”;
var stringArray = myVariable.split(“,”);
document.write(stringArray[0]);
document.write(stringArray[1]);
document.write(stringArray[2]);
document.write(stringArray[3]);
// -->
