Solution 1

On change of the TextBox, fire an event and inside that take the value of TextBox. Then call a stored procedure or write a query, which will split the word into letters and keep matching the words present in the required column.

when click button i want to remove a letter (anything i.e a or b or c) and show remaining in alert box

for example(deleting 'a' from text box entry and showing remaining in alert using javascript )
i have entered madhu in text box
i want to show in alert as mdhu

mystring = mystring.replace(/\/a/g, '');

Stored procedure? Query? Ummm....why?

Actually the question is edited. It was different before. The past question was to get the correct word from database.

Member 11382784 20-Jun-15 6:30am

yes sir ,
sorry for that

and how to bind the value to label . i have tried but it is not working

var str = document.getElementById('txtname').value;

str = str.replace(/[^c-z\.]+/g, '');
document.getElementById('Label1').value = str;

Try like below...

document.getElementById('Label1').innerHTML = str;

These are what you need to write the code:
1. Use substring()[^] method extracts the characters that you want from a string
2. Use ASP.NET 4.0 Client ID Feature[^] to identify the control in asp.net
3. Use the onblur Event[^] to fire the function.

function Click() {
alert("1");
var str = document.getElementById('txtname').value;

str = str.replace(/[^0-9\.]+/g, '');
alert(str);

by using this js am removing letters and it printing only numbers
actually i want to remove particlar letters a or b or c

You have changed the question. If you know the letter to remove, say a, or b, then str.replace(/[ab]+/g, ''); will do.
