how to validate gender by using radio button in java script

Hi Kalaivani0705


The first step is to create the radio buttons

<form name="myform">
<input type="radio" value="1st value" name="myradiobutton" />1st<br />
<input type="radio" value="2nd value" name="myradiobutton" />2nd<br />
<input type="submit" name="submitit" onclick="valbutton(myform);return false;" value="Validate" />
<input type="reset" name="reset" value="Clear" />
</form>



The next step is to validate using the java script.



function valbutton(thisform) {
// place any other field validations that you require here
// validate myradiobuttons
myOption = -1;
for (i=thisform.myradiobutton.length-1; i > -1; i--) {
if (thisform.myradiobutton[i].checked) {
myOption = i; i = -1;
}
}
if (myOption == -1) {
alert("You must select a radio button");
return false;
}

alert("Gender : " + thisform.myradiobutton[myOption].value);

// place any other field validations that you require here
thisform.submit(); // this line submits the form after validation
}


Hope this helps
