Validating data in javascript

15 Sep

To test wheter your input is an integer, you can use the Compare Validator (I'll add a sample).

The Validator controls check on the client AND on the server. NET has built-in validation controls that are able to cope with things like this: addition, make sure you don't rely on client-side validation only - check for an integer on the server-side, and reject the input if it isn't an integer.

This delegate simply displays the error condition in a message box.

If the save is successful, the Save Button_Click method uses the application-level state dictionary to store a value indicating that a new fill-up has just been saved. After the navigation, if the Summary Page finds the value stored in the state dictionary, it shows the first pivot item so that the user can immediately see the results of the fill-up.

Server-side validation incorporates code validation into a form handler. NET application on the server that provides the functionality that your form needs for processing after a customer has submitted it.

Now I want to know how to call function of Java Script in button and the function should do work like is button should send the text box value to the function and function should check the value to integer number only.The script has a catalog of almost all the common validation types built-in.The idea is to create a set of “validation descriptors” associated with each element in a form.//Begin function checkdate function checkdate(input) //Begin function button1_onclick //This makes sure that even if it somehow got past the original error check, //the report won't run unless the date format is correct.function button1_onclick(ctrl) //End function button1_onclick //This goes in the BODY portion of the HTML Add this phrase to any date control you want to call the function from: on Change="checkdate(this)" //We had to use onchange instead of onblur //because our call center software was interfering //with HTML code and causing the control to lose focus - // we ended up in an infinite loop of error messages.
