Id_ "+I;
var Aa=document.getelementbyid (ss). Value; if (eval (' Document.all.rbtid_ ' +i). Checked==true)//This is OK. The eval () function can turn a string of data characters into JS to run Var Bb=document.getelementbyid (ss);
if (document.getElementById (ss). Checked)//note checked cannot be written checked, otherwise it will not succeed {alert (AA);
Break
}
}
}
Or in the second way:
Get RadioButtonList
var Vrbtid=document.getelementbyid ("Rbtid");
Get all Radio
var vrbtidlist= vrbtid.getelementsbytagname ("INPUT");
for (var i = 0;i<vrbtidlist.length;i++)
{
if (vrbtidlist[i].checked)
{
var text =vrbtid.cells[i]. innertext;
var Value=vrbtidlist[i].value;
Alert (The text value of the selected item is "+text+" and the value is "+value");
}
In this method, RadioButtonList is treated as a table at the client, obtains all its child radio through the getElementsByTagName ("INPUT") method, and then loops each radio, The text value of the radio is then obtained by cells.
