我有一个包含拍卖产品的页面。按byd（bid）时会打开一个bootstrap模式。然后我改变金额。按下按钮。它会关闭模态，但在刷新页面之前不要更新数量。知道如何让它刷新。尝试了所有类似的问题。但是当我使用javascript它只是循环。也许我不知道在哪里输入它。 （我不卖河马:-)）Thx提前。这是代码：

答案 0 :(得分：2)
关闭按钮后重新加载页面。类似的东西：
<button type="submit" value="bud" class="btn btn-primary" onclick="window.location.reload()">BYD</button>
如果您想在更改后立即刷新，请添加条件以检查是否已执行更改，如果已执行更改，则刷新页面
