So getting to the point, always remember the KISS principle (Keep It Simple Stupid; Google it! It states that systems run smoothly when they are less complex, since we can get the validation feature from native Java Script/j Query then there seems no reason to include an extra validation plugin in your page for a couple of fields and increase the page load time (unless you tweak the plugin library very much, that totally depends upon the time).I want to create textbox on which if we paste a text with some special character example"Q!Somebody asked me this today on a support call so I did a few quick lookups online and found the solutions listed rather unsatisfying.The main problem with most of the examples I could dig up was that they only include numeric values, but that provides a rather lame user experience.This is done with the help of built in properties of Java Script strings; take the value of input textbox trim it and then check for empty string. In series of validation scheme there are various kind of validation scheme, Let’s some more different kind of validations.
Ok, here’s a fairly basic one – how to force a textbox to accept only numeric input.
After coding/debugging/testing, I finally developed the following code that totally runs smoothly even on Internet Explorer 6.0.
During development, I always encountered a scenario where we must allow only numbers as input in text fields (sounds like child's play, right? Since the validation of a plugin is provide by j Query, you can always include such plugins in your page to get a validation feature for input fields.
Email validation checks the following points Figure 2: Above two figures are example of valid and invalid emails.
This is validation to check that entered values are all letters or combination of different chars.
