Let us consider we have a function for validating all fields in the form. If I am changing the input of one particular field, the only field that has been changed should be validated but not other fields.
If you are using jQuery, you can use .bind() function to trigger on the change of the input box.
$("element").bind('change', function({}));

I need to write a JavaScript function which accepts IP range or subnets and validate it.
Like 10.0.0.1/24 should return true
10.0.0.1-10.0.0.10 should return true.
Use:
((\b|\.)(1|2(?!5(?=6|7|8|9)|6|7|8|9))?\d{1,2}){4}(-((\b|\.)(1|2(?!5(?=6|7|8|9)|6|7|8|9))?\d{1,2}){4}|\/((1|2|3(?=1|2))\d|\d))\b
http://regex101.com/r/aJ6jK2
This one also allows leading zeros:
((\b|\.)(0|1|2(?!5(?=6|7|8|9)|6|7|8|9))?\d{1,2}){4}(-((\b|\.)(0|1|2(?!5(?=6|7|8|9)|6|7|8|9))?\d{1,2}){4}|\/((0|1|2|3(?=1|2))\d|\d))\b

Before I had chosen.js I could find the specific option, remove it, and then create a new option instead, giving it the same value as it the deleted option has...
Now it doesn't work... the select itself changes - but it is hidden when using chosen.js...
And what was supposed to be a simple task is not simple at all!
Can someone help me?
Thanks!
Use $("#your_field").trigger("chosen:updated"); after updating select options.
Just as is written in reference: http://harvesthq.github.io/chosen/#change-update-events

I am trying to shake the input type text when validation fails in JQuery. Please someone tell me how it is to be done. Thanks
If you have jqueryui, you can
$( "#inputfield_id" ).effect( "shake" );
(replace inputfield_id with the id of your input field).

DHTML page which accepts user input into the text field as integers. when the user pressed the "Display" button, your function created in javascript should able to display the sum of the entire integers in an alert message.
Example
Input :
"21547524"
Output:
"2+1+5+4+7+5+2+4 = 30"
var input="21547524";
var additions=input.split('').join('+');
alert(additions+' = '+eval(additions));
