In ASP.NET, a CheckboxList control renders as follows:
---
<table id="Table1" border="0">
<tr>
<td><input id="cbl1_0" type="checkbox" name="cbl1$0" /><label
for="cbl1_0">Item One</label></td>
</tr>
<tr>
<td><input id="cbl1_1" type="checkbox" name="cbl1$1" /><label
for="cbl1_1">Item Two</label></td>
</tr>
...
</table>
---
It does not render a "value" attribute, so the only way to retrieve
the text is to query the innerText of the label at the same index. The
following script would be a working sample:
---
function checkSpecific(cbl, text)
{
var tblChkBoxList = document.getElementById(cbl);
var chkBoxList = tblChkBoxList.getElementsByTagName("input");
var lblList = tblChkBoxList.getElementsByTagName("label");
for (i = 0; i < chkBoxList.length; i++)
{
var currChkBox = chkBoxList[i];
var currLabelText = lblList[i].innerText;
if (currLabelText.lastIndexOf(text) > -1)
currChkBox.checked = true;
}
}
---
Note that the code works only in IE... other browsers do not support
the "innerText" property (Use "textContent", instead).
