Join them; it only takes a minute: Sign up How can I rewrite the ErrorMessage for a CustomValidator asp.net custom validator display dynamic control on the client? up vote 6 down vote favorite 1 I have a CustomValidator that is validating a telephone number for several different telephone numbering schemes. The client-side javascript looks like this: validatePhoneNumber(sender, args) { cleanNumber = args.Value.replace(/\D/, ""); country = $("#" + CountryID).get(0).value; switch (country) { case "North America": args.IsValid = validateNAPhoneNumber(cleanNumber); if (!args.IsValid) sender.errormessage = "* Not a NA Phone #"; break; case "UK": args.IsValid python exit = validateUKPhoneNumber(cleanumber); if (!args.IsValid) sender.errormessage = "* Not a UK Phone #"; break; ... } } The actual validation takes place properly, and the CustomValidator has the correct IsValid property at all times. The sender.errormessage, however, seems to be rewritten just after this function call to it's default value. How can I change the errormessage value, and make it "stick"? asp.net javascript validation client-side ecma262 share|improve this question edited Aug 5 '09 at 2:15 asked Aug 4 '09 at 22:46 Dustman 2,09772638 add a comment| 9 Answers 9 active oldest votes up vote 3 down vote The best way to change the error message of a validator control with image is: sender.innerHTML = "YOUR HTML WITH ANYTHING COME HERE" share|improve this answer edited Jul 25 '15 at 12:05 Falko 6,78572150 answered Jun 13 '12 at 4:47 Satyavir Yadav 312 add a comment| Did you find this question interesting?

you have probably seen some. There are (at least) two distinguishable kinds of errors: syntax errors and exceptions. 8.1. Syntax Errors¶ Syntax errors, also known as parsing errors, are https://docs.python.org/2/tutorial/errors.html perhaps the most common kind of complaint you get while you are still learning Python: >>> while True print 'Hello world' File "
packages that do the input/output stuff better (such as marshmallow). This means that it will be maintained until 2.0 but consider it deprecated. Don't worry, if you have code using that now and wish to continue doing so, it's not going to go away any time too soon. Flask-RESTful's request parsing interface, reqparse, is modeled after the argparse interface. It's designed to provide simple and uniform access to any variable on the flask.request object in Flask. Basic Arguments¶ Here's a simple example of the request parser. It looks for two arguments in the flask.Request.values dict: an integer and a string from flask_restful import reqparse parser = reqparse.RequestParser() parser.add_argument('rate', type=int, help='Rate cannot be converted') parser.add_argument('name') args = parser.parse_args() Note The default argument type is a unicode string. This will be str in python3 and unicode in python2. If you specify the help value, it will be rendered as the error message when a type error is raised while parsing it. If you do not specify a help message, the default behavior is to return the message from the type error itself. See error-messages for more details. By default, arguments are not required. Also, arguments supplied in the request that are not part of the RequestParser will be ignored. Also note: Arguments declared in your request parser but not set in the request itself will default to None. Required Arguments¶ To require a value be passed for an argument, just add required=True to the call to add_argument(). parser.add_argument('name', required=True, help="Name cannot be blank!") Multiple Values & Lists¶ If you want to accept multiple values for a key as a list, you can pass action='append' parser.add_argument('name', action='append') This will let you make queries like curl http://api.example.com -d "name=bob" -d "name=sue" -d "name=joe" And your args will look like this args = parser.parse_args() args['name'] # ['bob', 'sue', 'joe'] Other Destinations¶ If for some reason you'd like your argument stored under a different name once it's parsed, you can use the dest keyword argument. parser.add_argument('name', dest='public_name') args = parser.parse_args() args['public_name'] Argument Locations¶ By default, the RequestParser tries to pa
