Tomato form Validation Class Code modified version _ form effects

Once in the classic forum, personal projects in the background to deal with this thing, for simple form verification is very convenient.
Because you don't want the code to get too bloated, there's a lot of less-common functionality that doesn't add
I have not made any changes to the views of Foshan people, why? Because I'm lazy, haha
Today see Omeweb also modified a version, made a lot of changes, changed quite good, thank you.

The source code here:

Remove spaces on both sides of a string
String.prototype.trim = function () {
Return This.replace (/(^\s+) | ( \s+$)/g, "");
}
Detects whether a string is empty
String.prototype.isEmpty = function () {
Return! (/.? [^\s]+/.test (this));
}
Detects whether a value is between two specified values
String.prototype.isBetween = function (val, min, max) {
Return isNaN (val) = = False && val >= min && val <= max;
}
Get maximum or Minimum value
String.prototype.getBetweenVal = function (what) {
var val = this.split (', ');
var min = val[0];
var max = val[1] = = null? VAL[0]: val[1];
if (parseint (min) > parseint (max)) {
min = max;
max = val[0];
}
return what = = ' min '? (isNaN (min) null:min): (isNaN (max)? Null:max);
}
var validator = function (formobj) {
This.alltags = Formobj.getelementsbytagname (' * ');
String validation Regular expression

Get Control Name
This.getcontrolname = function ()
{
Return This.element.getAttribute (' controlname ') = null
? ' Specify the value of the control '

}
Set focus
This.setfocus = function (ele) {

Set Border color
This.setbordercolor = function (ele) {

Output Error Feedback information

Performing string validation
This.validate = function () {
var v = this.element.value;
Verify that Non-null is allowed
var required = This.element.getAttribute (' Required ');
if (required!= null && v.isempty ()) {
This.feedback (' required ');
return false;
}
Verify that the legal format is valid
var dataType = This.element.getAttribute (' DataType ');

try {
if (!) ( Eval (' This.reg. ' + dataType)). Test (v)) {

return false;
}
catch (e) {

}
Perform data validation
var confirm = This.element.getAttribute (' Confirm ');
if (confirm!= null) {
try {
var data = eval (' formobj. ' + Confirm + '. Value ');
if (v!= data) {
Alert (' Two input is inconsistent, please re-enter. ');
This.setbordercolor (this.element);
This.setfocus (this.element);
return false;
}
catch (e) {

Verify Number Size
var databetween = This.element.getAttribute (' Databetween ');

var max = databetween.getbetweenval (' Max ');

if (!v.isbetween (V.trim (), Min, max)) {
This.feedback (This.getcontrolname () + ' must be between ' + min + '-' + Max + '
The number between. ');

}
Verify character length
var datalength = This.element.getAttribute (' datalength ');
if (!v.isempty () && datalength!= null) {
var min = datalength.getbetweenval (' min ');
var max = datalength.getbetweenval (' Max ');
if (min = null | | max = NULL) {

This.feedback (This.getcontrolname () + ' must be ' + min + '-' + max + ' characters
。 ');

}

};
Perform an initialization operation
This.init = function () {
for (var i=0; i<this.alltags.length; i++) {
if (this.alltags[i].tagname.touppercase () = = ' INPUT ' | |
This.alltags[i].tagname.touppercase () = = ' SELECT ' | |

if (!this.validate ())
return false;

}
