  • Javascript plugins design pattern like jQuery

    - by Marco Demaio
    Could someone write down a very simple basic example in javascript to conceptualize (and hopefully make me understand) how the jQuery plugin design pattern is done and how it works? I'm not interested in how creating plugin for jQuery (so no jQuery code here at all). I'm interested in a simple explanation (maybe with a bit of Javascript code) to explain how it is done the plugin concept. Plz do not reply me to go and read jQuery code, I tried, but I it's too complex, otherwise I would have not post a question here.

  • MVC Validator.TryValidateObject does not validate custom atrribute, validateAllProperties = true

    - by nealsu
    When calling Validator.TryValidateObject with validateAllProperties = true my custom validation attribute does not get triggered. The ValidationResult does not contain an entry for my erroneous property value. Below is the model, attribute and code used to test this. //Model public class Model { [AmountGreaterThanZero] public int? Amount { get; set; } } //Attribute public sealed class AmountGreaterThanZero: ValidationAttribute { private const string errorMessage = "Amount should be greater than zero."; public AmountGreaterThanZero() : base(errorMessage) { } public override string FormatErrorMessage(string name) { return errorMessage; } protected override ValidationResult IsValid(object value, ValidationContext validationContext) { if (value != null) { if ((int)value <= 0) { var message = FormatErrorMessage(validationContext.DisplayName); return new ValidationResult(message); } } return null; } } //Validation Code var container = new Container(); container.ModelList = new List<Model>() { new Model() { Amount = -5 } }; var validationContext = new ValidationContext(container, null, null); var validationResults = new List<ValidationResult>(); var modelIsValid = Validator.TryValidateObject(container, validationContext, validationResults, true); Note: That the validation works fine and ValidationResult returns with correct error message if I use the TryValidateProperty method.

  • Best way to validate currency input?

    - by Abe Miessler
    I have created the TextBox and CompareValidator below which I thought would allow input in the following forms: 5 5.00 $5.00 Unfortunately it's not allowing the version with the dollar sign in it. What is the point of doing a type check against currency if you don't allow the dollar sign? Is there a way to allow this symbol? <asp:TextBox ID="tb_CostShare" runat="server" Text='<%# Eval("CostShare", "{0:$0.00}")%>' CausesValidation="true" /> <asp:CompareValidator ID="vld_CostShare" runat="server" ControlToValidate="tb_CostShare" Operator="DataTypeCheck" Type="Currency" ValidationGroup="vld" ErrorMessage="You must enter a dollar amount for 'Cost Share'." />

Valid strings: foo foo1 foo_bar fooBar Invalid strings: 1foo -- number as first character foo bar -- space föo -- punctuation ö Many thanks!

  • Validate authenticity of website owner

    - by Cyber Junkie
    Hello all! I'm planning to develop a web app where users will list their site/blog. When people submit their sites, how can I confirm that they are the owners of it? So for instance there is a user Mark who wants to submit someone else's website without their approval. I want to restrict Mark from doing so unless he is the actual owner. My idea was to do a comparison between the user's email domain and the website domain she/he wants to submit. If they match allow the user to submit the website. However most people don't register with their website domain address.. or perhaps I'll implement a Facebook connect in the future. What other methods would you suggest?

  • Validate NSString

    - by Chris
    I am validating an NSString to ensure that the string does not contain apostrophes. The code I'm using to do this is NSCharacterSet * invalidNumberSet = [NSCharacterSet characterSetWithCharactersInString:@"'"]; NSScanner * scanner = [NSScanner scannerWithString:string]; NSString * scannerResult; [scanner setCharactersToBeSkipped:nil]; [scanner scanUpToCharactersFromSet:invalidNumberSet intoString:&scannerResult]; if(![string isEqualToString:scannerResult]) { return 2; } Returning 2 represents an error. This code works, except for the case where the string is an apostrophe. To get around this issue, I added the following code above the preceding block. if([string isEqualToString:@"'"]); { return 2; } This code is evaluating to true, regardless of the input. I need to either prevent the first block from crashing with the input of ', or get the second block to work. What am I missing?
