jquery数组到字符串以显示文本框输入

Question

im trying to output the arrays associated with the test variable:

            $(document).on('click','#btnSubmit', function(){
                var test = $("input[name*='i_name']");                   
                $(test).each(function(i, item){
                    var sample = [];
                    sample.push($(item).val());

                });                 
            });

and display all the data i got into a textbox:

<input type="text" id="test" name="test[]">

how will i do it it? i tried JSON.stringify, .join but it only displays the last index of the array. please assist me.

You are resetting your sample array in every iteration, remove the variable declaration from the loop.

$(document).on('click','#btnSubmit', function() {
    var test = $("input[name*='i_name']");
    var sample = [];    // <-- Define sample variable here
    $(test).each(function(i, item){
        sample.push($(item).val());
    });

    console.log(sample.join(", "));
});
