Question

我正在尝试在javascript中将事件hanldler附加到beforeunload。这是我的代码：

$(window).on("beforeunload", function() {

    $("#popupin1").load("new.html");
})

我收到警报但是没有发生加载div。是否可以通过这种方式在关闭页面（弹出页面）时调用函数？

最后我得到了答案。在同样的代码中做了一些改变

AsyncRestTemplate asyncRestTemplate = new AsyncRestTemplate();
List<HttpMessageConverter<?>> messageConverters = asyncRestTemplate.getMessageConverters();

StringHttpMessageConverter stringMessageConverter = new StringHttpMessageConverter(Charset.forName("UTF-8"));
AllEncompassingFormHttpMessageConverter allEncompassingConverter = new AllEncompassingFormHttpMessageConverter();
allEncompassingConverter.setCharset(Charset.forName("UTF-8"));
allEncompassingConverter.setMultipartCharset(Charset.forName("UTF-8"));
allEncompassingConverter.setPartConverters(Collections.singletonList(stringMessageConverter));

for (Iterator<HttpMessageConverter<?>> iterator = messageConverters.iterator(); iterator.hasNext(); ) {
    HttpMessageConverter conv = iterator.next();
    if (conv instanceof AllEncompassingFormHttpMessageConverter) {
        iterator.remove();
    }
}
messageConverters.add(allEncompassingConverter);
asyncRestTemplate.setMessageConverters(messageConverters);

还需要

window.opener

使用“beforeunload”关闭弹出页面时加载页面
