Check radio button whose value = $ programmatically

Question

The switch group is defined:

<input type="radio" name="type0" value="$">$<input type="radio" name="type0" value="%">% 

It is necessary to check the first switch whose value = $ .

The problem is that the code below does not do this. Need to somehow avoid $

 $('input[type=radio][value=$]').attr('checked','checked'); 

Answer 1

 $('input[type=radio][value="$"]').first().attr('checked','checked'); 

Answer 2

this works for me, enclose the selector in double quotes and the selector of attributes in single

 $("input[type=radio][value='$']").attr('checked','checked');

Answer 4
