我有一个拍卖产品的页面。当按 byd(出价)时，它会打开一个 Bootstrap 模式。然后我改变数量。按下按钮。它关闭模式但在我刷新页面之前不更新金额。知道如何让它刷新。试过所有类似的问题。但是当我使用 javascript 时它只是循环。也许我不知道在哪里输入它。 (我不卖河马 :-))提前致谢。这是代码:

最佳答案

关闭按钮后重新加载页面。像这样的东西:

<button type="submit" value="bud" class="btn btn-primary" onclick="window.location.reload()">BYD</button>

如果你想在发生变化时刷新，那么添加一个条件来检查是否发生了变化，如果发生了，则刷新页面
