将javascript警报替换为模式
将javascript警报替换为模式
提问于 2013-09-11 17:44:14
如何用模式框替换javascript警报？
javascript警报是通过回显触发的，具体取决于某些数据库结果
if response is a
{
<script type="text/javascript">alert("response is a.");</script>
}
else
{
<script type="text/javascript">alert("response is not a.");</script>
}我正在使用bootstrap，如果我们可以用bootstrap模式替换警报，那么它是完美的

基于您可以在以下问题中找到的代码，我冒然为您创建了一个jsbin示例：JavaScript: Overriding alert()

一定要注意，覆盖alert可能不是一个好主意，特别是因为您会错过常规javascript警报的阻塞属性。正如您在我的示例中所看到的，如果您快速连续使用两个警报，则最后一个警报将覆盖之前的警报。

我的示例同时显示了'moo‘和'cow’。
