Im trying to validate mutiple asp textboxes in visual studio. I want to use jquery but i really can't seem to implement it. I keep getting errors relating to

Unable to get value of the property 'form': object is null or undefined

Can someone please give me explicit implementation instructions / code to get it working. The examples ive been trying are usint the Validator.addmethod() as im trying to ad regex validation.

Here is my effort so far

var alNumRegex = /^[\d\d?]+$/;    if (alNumRegex.test($('txtStones').val()))    { alert("Invalid Input"); }

Does Nothing

$.validator.addMethod(        "regex",        function (value, element, regexp) {            var check = false;            var re = new RegExp(regexp);            return this.optional(element) || re.test(value);        },        "Please check your input.");    $("#txtStones").rules("add", { regex: "^[\d\d?]+" })

Gives error - Microsoft JScript runtime error: Unable to get value of the property 'form': object is null or undefined
And points to this code in jquery.validate.js

C#

rules: function(command, argument) {
        var element = this[0];
        if (command) {
            var settings = $.data(element.form, 'validator').settings;
            var staticRules = settings.rules;
            var existingRules = $.validator.staticRules(element);
            switch(command) {
            case "add":
                $.extend(existingRules, $.validator.normalizeRule(argument));
                staticRules[element.name] = existingRules;
                if (argument.messages)
                    settings.messages[element.name] = $.extend( settings.messages[element.name], argument.messages );
                break;

This line in particular

var settings = $.data(element.form, &#39;validator&#39;).settings;

Here is the full html page im using. At the moment im just trying to validate one textbox to get it working then i will be validating a further 5.

Solution 1

The first and most obvious thing is that your form in the page is called "form1" and not "form", so it make complete sense that the javascript cannot find it.
