accessing the input elements with array names in jquery

[omerbutt]

hi i have a problem i was using version 1.3 for jquery and i upgraded it to 1.8 and suddenly my code became buggy , i had 2 radio inputs with the name representative_select[]

<input name="representative_select[]" type="radio"  />
 

and i need to check that if any one of these radio buttons is selected or not my previous working code was

if(jQuery("input:radio[name=payment_option[]]:checked").length==0){
        str+='Please Select a Payment option\n';
    }
 

and after upgrade i starting receiving syntax error i did some R&D and found that some functions are deprecated in the version 1.6+, so i changed it to the following but still no use as the square brackets need to be escaped so the \\ are used but still i am not doing it right here it is

if(jQuery(name="representative_select\\[\\]").prop('checked').length==0){
        str+='\Select a Representative option';
    }
 

then i gave an id to the same input id='single_rep'
and then run these two statements

alert(jQuery("#single_rep"));
alert(jQuery(name="representative_select\\[\\]"))
 

both of these statements alerted [object object]
but when i append the prop() function with the 2 statements

jQuery(name="representative_select\\[\\]").prop('checked')
jQuery("#single_rep").prop('checked')
 

the first one says that prop is undefined and the second statement alerts true /false depending on the radio being checked or un-checked

can somebody help me in this regard that what do i need to do

A silly question! Why do you put [] in the name for a radio button?

if you cant give a solution do not reply ANAS , do have some respect for other around the community, if you could have understood what i said then it would have been a lot better, a silly question is what you replied

Why do you put [] in the name for a radio button?

we can put [] with any type of input's name if we want to collect all of those input values into an array when posting on another page so please if you cant help dont be a DUMB ASS

Although I thought it was a silly question, you didn't get the point I wanted you to get. Having an array of values for any input type makes sense except for radio buttons -you have only one value selected. Do you agree with me on that?

Regarding your point of respect, I think you need to learn how to respect others before you ask them to respect you. A community is not aimed for only answering your solutions. What you are asking for is a narcissistic community.
When someone asks you a question respond to him with all the respect you want others to show you.

Although I don't want to respond to you, I will through this feeling away now and tell you how to implement this if you still have a need:

if($("[name='representative_select[]']:checked").length==0){
    alert('Select a Representative option');
}
 

Please let me know if you need further clarifications.
