<input type="radio" name="radio" id="yes" value="pickup" onBlur="trim('pickup')" />
Yes.</td>
<td width="55%"><input type="radio" name="radio" id="usps" value="no" onBlur="trim('usps')" />
No.</td>
This is the JS Validation Code I found online and that I'm using but it only validates text fields, not radio buttons:
- Code: Select all
function $$(id) {
try {
var tmp = document.getElementById(id).value;
}
catch(e) {
alert("Field " + id + " does not exist!\nvalidation is configured on a field with no ID");
return false;
}
if(tmp == "") {
alert("Field " + id + " cannot be empty");
return false;
}
return tmp;
}
var required = {
field : [],
add : function(name, type) {
this.field[this.field.length] = [name,type];
},
out : function() {
return this.field;
}
}
var validate = {
check : function() {
var tmp;
// loop all required fields
for(var i=0; i<required.field.length; i++) {
// check the form field exists
this.tmp = $$(required.field[i][0]);
if(this.tmp) {
if(this.checkit(required.field[i][0],required.field[i][1])) {
// validated okay
} else {
alert("Field "+required.field[i][0]+" not valid\n");
document.getElementById(required.field[i][0]).focus();
return false;
}
} else {
try {
document.getElementById(required.field[i][0]).focus();
} catch(e) { }
return false;
}
} // for
return true;
},
checkit : function(value,type) {
exp : '';
switch(type) {
case "NOT_EMPTY":
if(this.trim($$(value)).length < 1) { return false; } else { return true; }
break;
case "ALPHA":
exp = /^[A-Za-z]+$/;
if($$(value).match(exp)==null) { return false; } else { return true; }
break;
case "ALPHASPACE":
exp = /^[A-Za-z ]+$/;
if($$(value).match(exp)==null) { return false; } else { return true; }
break;
case "NUMERIC":
exp = /^[0-9]+$/;
if($$(value).match(exp)==null) { return false; } else { return true; }
break;
case "NUMERICPLUS":
exp = /(^-*\d+$)|(^-*\d+\.\d+$)/;
if($$(value).match(exp)==null) { return false; } else { return true; }
break;
case "ALPHANUM":
exp = /^[a-zA-Z0-9]+$/;
if($$(value).match(exp)==null) { return false; } else { return true; }
break;
case "ALPHANUMSPACE":
exp = /^[a-zA-Z0-9 ]+$/;
if($$(value).match(exp)==null) { return false; } else { return true; }
break;
case "EMAIL":
exp = /^[a-zA-Z0-9._%-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;
if($$(value).match(exp)==null) { return false; } else { return true; }
break;
case "YYYYMMDD":
exp = /^(19|20)[0-9][0-9][- /.](0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])$/;
if($$(value).match(exp)==null) { return false; } else { return true; }
break;
case "DDMMYYYY":
exp = /^(0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.](19|20)[0-9][0-9]$/;
if($$(value).match(exp)==null) { return false; } else { return true; }
break;
case "MMDDYYYY":
exp = /^(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)[0-9][0-9]$/;
if($$(value).match(exp)==null) { return false; } else { return true; }
break;
default:
exp = new RegExp(type);
if($$(value).match(exp)==null) { return false; } else { return true; }
} // switch
},
trim : function(s) {
return s.replace(/^\s+/, '').replace(/\s+$/, '');
}
}
function $val(id) {
return document.getElementById(id);
}
function trim(id) {
$val(id).value = $val(id).value.replace(/^\s+/, '').replace(/\s+$/, '');
}
Can someone please, please, please tell me what and where to add the validation for radio buttons? Should my form include 'onBlur' for radio buttons? BTW, I'm using PHP to process the form. Thanks so much.
