How to get the id of the textbox on keydown event of that textbox

Question

I have a text box in my page:

<td>
<input type="text" id="Approvers1" size="11" onkeydown="AddUsersKeyDown(event)" style="width: 470px;" />
</td>

This is my js function:

function AddUsersKeyDown(evtobj) {

    if (evtobj.keyCode == 75 && evtobj.ctrlKey) {

        AddUsers(--input parameter--);
    }
}

Now if i press ctrl k in my textbox it must call another javascript function named AddUsers(--input parameter--).. where the input parameter should be the id of the textbox...

How to achieve this.. Either i need the id of the textbox or atleast the DOM object so that i can access the id of textbox from DOM object..

Kindly help me in achieving either one of the two things..

Answer 1

Use this to get the DOM element or this.id to get the id of the element

<td>
<input type="text" id="Approvers1" size="11" onkeydown="AddUsersKeyDown(event,this.id)" style="width: 470px;" />
</td>

function AddUsersKeyDown(evtobj,id) {

    if (evtobj.keyCode == 75 && evtobj.ctrlKey) {

        AddUsers(id);
    }
}
