create checkbox when selection is made from dropdown


Recommended Posts

hello @LL,

I have some dropdown

<select name='selectedProd'>

<option value='code1'>event 1,IL</option>

<option value='code2'>event 2, IL</option>

I want to create checkbox visible only if user picks event 1 from dropdown, but checkbox would not show up if event 2 will be selected.

is that possible?

thanks

What you could do, is have the checkbox visible at all times, but only able to use when option one has been picked by using a javascript code, such as this:

function updatefields(){
if (document.getElementById("selectedProd").options[document.getElementById("selectedProd").selectedIndex].value=='code1')
{
document.getElementById("checkbox").disabled=false;}
else{
document.getElementById("checkbox").disabled=true;
}
}

<input type="checkbox" name="checkbox" id="checkbox"/>

Hoped that helped.

You could also make the checkbox initially hidden :

<input id="checkboxNamedID" type="checkbox" style="display: none;">

Then in your javascript show it with :

document.getElementById('checkboxNamedID').style.display = '';

And hide it again with :

document.getElementById('checkboxNamedID').style.display = 'none';
