enable textbox if others is selected in drop down list

[sundarraj_mca]

hai developers,

in my form i have a drop down menu in which others option is stated at last.

if user clicks others option i want to enable the text box below which is disabled by default.

Give your select box and id. For example:

Code: Select all

<select id="myselect">


..Now if you're done giving it an id, give your input box and id too. Example would be:

Code: Select all

<input type="text" disable="disable" id="myinput">


...Now when you're finished doing thosse, you need to decide when you want the even to trigger..either onchange (option box is change) or onclick (triggered by a button).

If you want the earlier, then this code would suffice, using the id's i've given as example.

Code: Select all

window.onload=function()
{
var select=document.getElementById('myselect');
var inps=document.getElementById('myinput');
select.onchange=function()
{
switch(select.value)
{
case 'others':
inps.disabled=false;
break;
}
}
}


Note that your other's option box value should be others, or else, change this part to what your value is:

Code: Select all

case 'others':


IF you want an event triggered via onclick, don't hesitate to come back.
