How to disable button in ASP.NET

Question

I have an onclick code on my image to disable the button on my form that look like this

<img alt="" src="images/search-icon.png" width="16" height="16" style="display: inline;height:16px;cursor:pointer; width: 16px;" onclick="DisableButton('<%=btnSave.ClientID %>');" />

And then on my javascript I have a code like this

function DisableButton(bSave) {
document.getElementById(bSave).attributes("Enabled", false);
}

the problem is it is not working, everytime i click on the image nothing happens. Is there an error on my code? Please help me on this one. Thank you in advance.

There is no attributes in JavaScript and there is no Enabled property in HTML. — epascarello

Use document.getElementById("idofyourbutton").disabled=true; — Arunprasanth K V

That's not keyboard accessible. To fix it, wrap the img in a button, move the onclick to the button and change the alt text to alt="search". — danielnixon

Use 'disabled'

document.getElementById(bSave).disabled = true;

Clearing up the disable vs disabled ambiguity.

Here's code :

 document.getElementById(bSave).disabled = true;

Or

document.getElementById('<%= btnSave.ClientID %>').disabled = true;

Please use this it will work In your script :

document.getElementById(bSave).disabled = true;

if you are using jquery then

 $("#"bSave).prop("disabled",true);
