div disappears when page refreshed
Question
Can't figure out why the below piece of code makes the textfield disappear upon page refresh (when 'No' radio button selected). Also, after the page is refreshed the default radio button doesn't get selected.
Forcing refresh, fixes the problem, though.
Any ideas?
<html>
<body>
<div class="editfield">
<div id="field_1">
<label>
<input type="radio" checked="checked" name="radio-1" id="radio-1_id" value="Yes" onclick="document.getElementById('divUrl').style.display='none'">Yes
</label>
<label>
<input type="radio" name="radio-1" id="radio-2_id" value="No" onclick="document.getElementById('divUrl').style.display='block'">No
</label>
</div>
</div>
<div class="editfield" id="divUrl" style="display:none">
<label>Website URL</label>
<input type="text" name="X" id="X_id" value="" />
</div>
</body>
</html>

The page refresh will initiate the page in its' original state. So the
style="display:none"
will be reactivated on the div and will be hidden and the "Yes" button will also be reenabled

<!DOCTYPE html>
<html lang="en-US">
<body onLoad="document.getElementById('radio-2_id').checked=false; document.getElementById('radio-1_id').checked=true;">
<div class="editfield">
<div id="field_1">
<input type="radio" checked="checked" name="radio-1" id="radio-1_id" value="Yes" onclick="document.getElementById('divUrl').style.display='none'">
<label for='radio-1_id'>
Yes
</label>
<input type="radio" name="radio-1" id="radio-2_id" value="No" onclick="document.getElementById('divUrl').style.display='block'">
<label for='radio-2_id'>
No
</label>
</div>
</div>
<div class="editfield" id="divUrl" style="display:none">
<label>Website URL</label>
<input type="text" name="X" id="X_id" value="" />
</div>
</body>
</html>
just a short recap:
1. on page refresh the div should disappear (all css and js and html that was dynamically set / added is removed) and the selected radio button should be the first (Yes)
2. tested this on all major browser and it works
3. still can't figure out why it wasn't working on Mozilla and IE without the JS refresh
I moved the radio buttons out of the labels to see if that impacted the refresh in any way and it didn't. Also, I removed an extra </div> that was in the original code.

我所做的首先有一个 textarea 插入编号，0 使其只读，然后它不会在刷新时消失，插入 document.getElementById("demo").readOnly=false，true 以启用只读
