Question

I need to fetch all span values in a div into array or string

var tag_text_arr=$("#div_id span").each(function(){
        return $(this).text();
    });

Actually i need to fetch all span values inside div and want to create a string like this

span1_val|span2_val|span3_val|span4_val

If this is possible explain me…

This should output your required string:

var arr = [];
$("#div_id span").each(function(index, elem){
    arr.push("span" +index+ "_" + $(this).text());
});
return arr.join("|");

This will start the numbering at span0, not span1. If you want it to start at span1, use +(index + 1)+ instead of +index+. (example)

If I read your question wrong (and you don’t want spann_ prefixed to each element in the string, you can just use jQuery’s $.map() function:

var tag_text_arr = $.map($("#div_id span"), function(elem, index){
    return $(elem).text();
}).join("|");

return tag_text_arr;
