var cp = $ ("INPUT [name = 'cpid']"). Val ();

for (var I = 0; I <cp.length; i ++) {

var CPP = cp.charat (i);

if (! Reg.test (CPP) || CPP.MATCH (/^([AZ])+$/) || cpp.match (/^/d+$/)) {// Verification of uppercase letters, numbers and Chinese

document.GetelementByid ("DIV2"). Style.display = "Block";

document.GetelementByid ("DIV2"). STYLE.COLOR = "Red";

$ ("#DIV2"). Text ("*Must all enter a lowercase letter !!!");
