I have been working on a script to enable and disable a field using Javascript. It functions correctly in Internet Explorer, but I am encountering issues with Safari.
FIELD If "Yes" is selected, the free text field below should be enabled; otherwise, it should be disabled.
<tr id="ContainerQ1266I1396">
<td>Ultrasound Used</td>
<td>
<input type="radio" name="Q1266I1396" id="Q1266I13960" onclick="">No</input>
<input type="radio" name="Q1266I1396" id="Q1266I13961" onclick="regft();">Yes</input>
</td>
</tr>
<tr id="ContainerQ1267I1276">
<td>fretext</td>
<td>
<input id="Q1267I1276" type="text"size="80" />
</td>
</tr>
JAVASCRIPT
function regft(){
var regf=document.getElementById("Q1266I13961");
document.getElementById("ContainerQ1267I1276").disabled=true;
if (regf.checked==true){
document.getElementById("ContainerQ1267I1276").disabled=false;
}
}
