原标题:sum all input elements in jquery

说明如何写出一个分类公式,把从钥匙上开始的所有投入领域汇总起来...... 我尝试以下法典,但没有发生。 没有错误,也没有更新。 ( html位于最底层)

$(document).ready(function(){
    /* sums pull total input fields */
    $("input[name^= pull ]").bind("keyup", "calcPullTotal");
    calcPullTotal();
});


function calcPullTotal() {
    $("[id=totalpull]").calc(
        "pullnum + 0", { pullnum: $("input[name^=pull]") },
        function (s){
            return s.toFixed(0);
        },
        function ($this) {
            var sum = $this.sum();
                $("#totalpull").text(
                sum.toFixed(0)
            );
        }
    );  
}
<table id="convert">
<tbody>
<tr><td><input type="text" value="" name="pull0" /></td></tr>
<tr><td><input type="text" value="" name="pull1" /></td></tr>
<tr><td><input type="text" value="" name="pull2" /></td></tr>
<tr><td><input type="text" value="" name="pull3" /></td></tr>
</tbody>

<tfoot><tr><td><input type="text" id="totalpull" name="totalpull" value="" /></td></tr></tfoot>
</table>
最佳回答

Try:

$("input[name^= pull ]").bind("keyup", calcPullTotal);
calcPullTotal();

您通过“指示数”作为第二个论点,即bind,该理论希望有tus
