Evaluating specific array value using jQuery or JavaScript -

i have 160 inputs in page. want add every 8 inputs , output elsewhere. instead of manually using

var total1 = inputvals[0] + inputvals[1] + inputvals[2] + inputvals[3] + inputvals[4] + inputvals[5] + inputvals[6] + inputvals[7] + inputvals[8]; 

i want function can specify starting , ending index addarray(9, 17) , add values between , return it. prefer function in javascript jquery ok.

suppose have <input> elements defined as:

<input type="text" class="myinput" /> <input type="text" class="myinput" /> <input type="text" class="myinput" /> ... 

you can create method job of jquery:

function add(start, end) {     var total = 0;     $(".myinput").slice(start, end).each(function() {         total += +this.value;     });     return total; } 

the same method in pure javascript like:

function add(start, end) {     var total = 0,         inputs = document.getelementsbyclassname("myinput");      (var = start; < math.min(end, inputs.length); i++) [         total += +inputs[i].value;     });     return total; }
