问题描述
我正在使用一种方法来计算此ID id="salenag<?PHP echo $a; ?>" 的值
使用PHP来自数据库的多个值，然后将值添加到输入字段中，所有所有输入字段的总和以id no sale_nag显示。
我为此使用了Javascript方法，但是没有用；
它如何正常工作，用于销售点库存不足。我想要一个解决方案。请帮帮我。
<input type='text' value='0' id='sale_nag'>

首先，将功能更改为此：
jQuery现在，为您的输入创建一个jQuery处理程序
function chachvalue(element) {
// get value of input that unfocused
var x1 = parseInt(element.val());
// select #sale_nag element
var sale_nag = $('#sale_nag');
// set value of sale_nag to sale_nag + x1
sale_nag.val(parseInt(sale_nag.val()) + x1);
}
现在您的输入元素可以简化为
$('.outnag_input').on('focusout',function() {
chachvalue($(this));
});
还应该将<input name="outnag[]" class="outnag_input" value="0" type="text"/>
函数和chachvalue()处理程序移到PHP循环的外部。
