Hi,
First add the reference of jquery library then call this method.
"text/javascript" src="http://code.jquery.com/jquery.min.js">
"text/javascript">
function Enablecontrols()
{
alert("Javascript function is called");
}

You can use button as well. Here an example of both. https://jsfiddle.net/gbymxfkL/
function Enablecontrols() {
    document.getElementById('fname').disabled = false;
}

function disableControls() {
    document.getElementById('fname').disabled = true;
}

function enableControlsSubmit() {
    document.getElementById('fname').disabled = false;
    return false;
}

function disableControlsSubmit() {
    document.getElementById('fname').disabled = true;
    return false;
}
First name: <input type="text" id="fname" disabled><br><br>
<input type="button" value="Enable Textbox" onclick="Enablecontrols()">
<input type="button" value="Disable Textbox" onclick="disableControls()">

<br><br>
<input type="submit" value="Enable Textbox - Submit button" onclick="return enableControlsSubmit()">
<input type="submit" value="Disable Textbox - Submit button" onclick="return disableControlsSubmit()">

If you don't want to submit the form then return false from that function.
