onrowdatabound ，从数据库取值得，如果checkboxOK ==true, 如何将checkboxCritical的disable set false，并保证javascript也好用

Question

gridview中，有4个checkbox,如果选择OK, 就要使Critical变成disabled,用javascript已经实现（如下），并在onrowdatabound时，从数据库取值得时候，如果checkboxOK ==true, 如何将checkboxCritical的disable set false，
ASPX
<script type="text/javascript" language="javascript">
function StatusGridCheckbox(CheckCritical)
{
  document.getElementById(CheckCritical).disabled= !document.getElementById(CheckCritical).disabled;
            
}

Answer 1

你查看生成的html源码可以得知，当CheckBox的Enabled被设为false时，编译器会在生成的checkbox外面加了一层span，所以被disabled的其实是span，RowDataBound事件中的代码你可以不用修改了，尝试下把js改一下：function StatusGridCheckbox(CheckCritical)
{
  var cb = document.getElementById(CheckCritical);
  var p = cb.parentElement || cb.parentNode;
  if(p != null && p.tagName.toLowerCase() == "span") {
      p.disabled = !p.disabled;
  }
  else {
      cb.disabled = !cb.disabled;
  }
} 

Answer 2

打开画面，checkboxOK已经Checked,点击checkboxOK，将其设置成Unchecked,希望CheckboxCritical的disable=false,怎么办

Answer 3

这个方法，在画面打开并且CheckboxOK.Checked=true,CheckboxCritical.enable=false的情况，不好用

Answer 4

HTML
<td style="width:2%;">
                                    
                                    <input id="GridView1_ctl02_txtCheckOK" type="checkbox" name="GridView1$ctl02$txtCheckOK" checked="checked" onclick="javascript:StatusGridCheckbox('GridView1_ctl02_txtCheckCritical');" />
                                </td>
<span disabled="disabled"><input id="GridView1_ctl02_txtCheckCritical" type="checkbox" name="GridView1$ctl02$txtCheckCritical" disabled="disabled" onclick="javascript:StatusGridCheckbox('GridView1_ctl02_txtCheckOK');" /></span>
