javascript - document.getElementById（）。value和document.getElementById（）。选中不适用于IE(document.getElementById().value and document.getElementById().checked not working for IE)

Question

I tried to assign a new value into the hidden input and checkbox of an input form.

(我尝试将新值分配给输入表单的隐藏输入和复选框。)

It's working fine in Firefox but not in IE (I'm using IE 7).

Does anyone know what is wrong with my code?

(HTML：)

<input type="hidden" id="msg" name="msg" value="" style="display:none"/>
<input type="checkbox" name="sp" value="100" id="sp_100">

Answer 1

For non-grouped elements, name and id should be same.

(对于非分组元素，name和id应该相同。)

In this case you gave name as 'sp' and id as 'sp_100'.

(在这种情况下，您将名称命名为“sp”，将id命名为“sp_100”。)

Don't do that, do it like this:
