Gridview编辑时Jquery自动计算自定义列（鼠标离开输入框Jquery计算）

Jquery片段：

<script type="text/javascript">

        function compute(nbBoxQuantity, lblQuantityPerBox, lblQuantity, nbPrice, lblTotalAmounts) {

            if (nbBoxQuantity.value == "" || nbBoxQuantity.length == 0) {

                nbBoxQuantity.value = 0;

            if (lblQuantityPerBox.innerText == "" || lblQuantityPerBox.length == 0) {
