Using Dynamic Table Dropdown to Disable Radio Button

Question

I just need some clarification with the JQuery/JavaScript syntax.

for (var i=0;i<tableb.rows.length;i++){
    var roway = tableb.rows[i];
    if($(roway).find("input[id='location']")=='rr'){
        alert("eeee");
       }
   }

The above isn't working, and I'm not too certain how to specify when the "rr" value is selected in the dropdown with the location id.

Thanks in advance.

Answer 1

Can I see your html?

Why do you have multiple id's in the first place? Anyways

for (var i=0;i<tableb.rows.length;i++){
    var roway = tableb.rows[i];
    if($(roway).find("input#location").val()=='rr'){
        alert("eeee");
       }
   }

In case you have only 1 input with that ID then a cleaner way is

if($("input#location") && ("input#location").val() == 'rr') {
    alert('eeee');
}
