JQuery for循环，用于向量

Question

我正在尝试制作一个矢量计算器来练习我的jquery技巧，我有一个问题。我有一个.option div，我有力量和角度的场。如果我单击#calc_v按钮，则会插入另一个字段。

<div class="option">
   <h2>Vectors</h2>
<a class="close">Close X</a><br/>
<div id="move">1.<input type="number" step="0.01" id="N1"/> Newtons(or meters) à <input type="number" step="0.01" id="A1"/> Degrees
<br/></div>
<button id="calc_v">Calculer</button>

<a id="add_move">+ VECTOR</a>
<div id="log_v"></div>

这是我的jquery代码：

<script>
//vectors
var vector = 1;

$("#add_move").click(function () {
    vector++;
    $("#move").append(vector+".<input type='number' step='0.01' id='N"+vector+"'/> Newtons(ou mètres) à <input type='number' step='0.01' id='A"+vector+"'/> Degrées<br/>");
});

$("#calc_v").click(function(){
    var x_v = 0;
    var y_v = 0;
    var ite = 0;
    for(x=1; x <= vector; x++){
        //for each added vector give it a var name
        ite++;
        var f = "#N"+ite;
        var a = "#A"+ite;
        //then, find its value
        var force = $(f).val();
        var f_val = parseFloat(force);
        var angle = $(a).val();
        var a_val = parseFloat(angle);

        //analyse it
        var cons_x = ((f_val)*(Math.cos(a_val))) * (180 / Math.PI);
        var cons_y = ((f_val)*(Math.sin(a_val))) * (180 / Math.PI); 
        //add it to each x,y coords
        x_v += cons_x;
        y_v += cons_y;
    }
    $("#log_v").html("Coords: ("+ x_v + ","+ y_v + ") |f"+force +"|a"+ angle +"|i"+ ite+"|v"+vector);
});
