How to limit the character entry into a text box in jQuery?

Hi All,
        I had come across a situation where i need to limit the character count into a text box. Suppose, your there is a requirement where the text box should take only 20 characters.


In this situation preferably use the keypress method for even to happen as follows

$('#IdOfTheTextBox’).keypress(function (e) {
              if (e.which < 0x20) {
//This snippet you have to use , otherwise it will not allow you perform action using  backspace or delete button on FireFox
                     return;
              }
              if (this.value.length == "20") {
                     e.preventDefault();
              }
              });

By doing above, it will not allow you to enter characters after 20the character.

Hope this will help .
cheers

Programmatically read the value from web.config file

Here is a situation where you need to keep a key value pair element in the web.config file and read them during the run time. I suggest, better keep key /value pair under <appSettings> element and read it programmatically . <appSettings>   <add key=" LicenseKey " value=" 987jKouterhsk " /> </appSettings> Assume , you have added a license key as above in the web.config file. You need the license key during run time. You can access the license key class named "ConfigurationManager". write a property  called getLicenseKey and return the corresponding license key. public string GetLicenseKey {    get{   return  ConfigurationManager.AppSettings[" LicenseKey "]; } } Now the property GetLicenseKey will have the value 987jKouterhsk. Use this value as per your requirement. -Cheers Pradeepa Achar
