推荐答案
我认为您无法以尝试的方式访问名为"se"的广播收藏集.替换此代码:
Hi,
I don''t think you can access the radio collection named ''se'' in the way you''re trying to. Replace this code:
function jksitesearch(curobj)
{
for (i = 0; i < document.jksearch.se.length;i++ )
{ //loop through radio to see which is checked
if (document.jksearch.se[i].checked == true)
switchaction(document.jksearch.se[i],i)
}
document.getElementById("hiddenquery").value = "site:" + domainroot + " " + curobj.qfront.value
}
带有:
With:
function jksitesearch(curobj)
{
var se = document.getElementsByName('se');
for (i = 0; i < se.length;i++ )
{ //loop through radio to see which is checked
if (se[i].checked == true)
switchaction(se[i],i)
}
document.getElementById("hiddenquery").value = "site:" + domainroot + " " + curobj.qfront.value
}
