check only one RequiredFieldValidator using JavaScript

Question

I have Multi RequiredFieldValidators in my Page I want to check validate of one of them using Javascript Function can any one help me

Your question is not clear, What are you trying to do ? enable/disable validation controls ? OR Check validity of controls via JavaScript ??? — yogi, Sep 11 '12 at 08:53
Means you want to validate a control via JavaScript, If it is so you can use CustomValidator control and write your JavaScript function and provide that function to CustomValidator's ClientValidationFunction. See this http://www.w3schools.com/aspnet/control_customvalidator.asp property. — yogi, Sep 11 '12 at 08:57

You can try with validationgroup on you validator and button submit

sorry its not i need, I have textbox that validate with RequiredFieldValidator , and i want to check if it validate before write some Javascript code , but without check all page validate – Mario Soft Sep 11 '12 at 09:01
In this case you use validationgroup he permits you to separate your validations and not valid all datas – Aghilas Yakoub Sep 11 '12 at 09:05
ok but i need to check the RequiredFieldValidator validation with javascript to do somthing with javascript if it valid – Mario Soft Sep 11 '12 at 09:06
for your case i recommend you to use CustomValidator because your logic is not adapted to RequiredFieldValidator – Aghilas Yakoub Sep 11 '12 at 09:11

Try something like this in your javascript code:

for (i = 0; i < Page_Validators.length; i++) {

                if (Page_Validators[i].Errormessage=="your Error message") {
                    //your code...
                }
            }

using above code you can differentiate on the basis of your error message.

Or you can try this, but I am not sure if it work or not:

function abc(id){
    for (i = 0; i < Page_Validators.length; i++) {

                    if (Page_Validators[i]==id) {
                        //your code...
                    }
                }
}

in above code 'id' is the clientid of your particular validator, I am trying to check if two validators are same or not or you can check there equality using any of their unique property to reach your particular validator.
