Client id method javascript

 <input type="text" id="txtFirstName" runat="server" class="textReg"                                         
 onblur="javascript:validate_input(<%=txtFirstName%>,'imgFirstNameS','imgFirstNameE');" />`

I want to send control id to my javascript function

like ctl00_ContentPlaceHolder1_txtFirstName

or 

function validate_input(control, success, error) {
control = document.getElementById('<%='+control+'.ClientID %>');
}

is it possible ?

To answer the direct question, here is the proper syntax for this:

<input type="text" id="txtFirstName" runat="server" class="textReg"                                         
 onblur="validate_input('<%=txtFirstName.ClientID%>', 'imgFirstNameS', 'imgFirstNameE');" />

However TurBas idea is better, pass this and use it directly.

Since you are using jQuery remove your inline js handler and put something like

If you want to hook the event for a bunch of textboxes having the class testReg then you can do something like

$("input:text.textReg").blur(function(){
    validate_input(this, 'imgFirstNameS', 'imgFirstNameE');
});

If you want this for the textbox with id txtFirstName only then you can have something like

$("<%= txtFirstName.ClientID %>").blur(function(){
   validate_input(this, 'imgFirstNameS', 'imgFirstNameE');
});

Why send the Id if the next thing you do is get the item by Id. Just put 'this' as first parameter.

<input type="text" id="txtFirstName" runat="server" class="textReg"  
onblur="validate_input(this,'imgFirstNameS','imgFirstNameE');" />
