javascript - How do I build a valid JQuery selector using variables -

i trying build jquery selector. involves concatenating string , variables. however, reason, resulting selector comes invalid. have attempted number of options such this:

$('[name="[name='$radioname + (row_id) + ']"][value="$result"]').attr('checked',true);

$radioname illustration is: 'nigeria[osun][okuku-;// angle bracket not closed row_id appended before closing bracket appended shown above.

$result illustration is: '67

row_id illustration is: 5

how may build valid descriptor these requirements?

thanks

try:

$('[name="' + $radioname + row_id + ']' + '"][value="' + $result + '"]').attr('checked',true);

when i'm putting concatenated expressions, using write static text proper quotes first. like:

$('[name=""][value=""]').attr('checked',true);

then paste in '+ +' in each of spots want add together variable. so:

$('[name="'+ +'"][value="'+ +'"]').attr('checked',true);

then lastly, add together variable:

$('[name="'+ $radioname + row_id + ']' + '"][value="'+ $result +'"]').attr('checked',true);
