小问题.急求
.code
{
background-image:url(code.jpg);
font-family:Arial;
font-style:italic;
color:Red;
border:0;
padding:2px 3px;
letter-spacing:3px;
font-weight:bolder;
}
.unchanged
{
border:0;
}
var code ; //??? ?????
function createCode()
{
code = "";
var codeLength = 5;//??????
var checkCode = document.getElementById("checkCode");
var selectChar = new Array(0,1,2,3,4,5,6,7,8,9,'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');//????????????,?????????
for(var i=0;i<codeLength;i++)
{
var charIndex = Math.floor(Math.random()*36);
code +=selectChar[charIndex];
}
// alert(code);
if(checkCode)
{
checkCode.className="code";
checkCode.value = code;
}
}
function validate ()
{
var inputCode = document.getElementById("input1").value;
if(inputCode.length <=0)
{
return false;
alert("Enter the verification code!");
createCode();
}
else if(inputCode != code )
{
return false;
alert("code Mistake!");
createCode();//?????
}
else
{
alert("OK");
document.form.submit();
}
}
如何将<input name="text" type="text" class="unchanged" id="checkCode" style="width: 80px" />
这个东西打开的时候就显示出来呢?
[解决办法]
在body里,写ONLOAD = createCode 不行吗?
