我尝试在通过ajax调用加载的页面上实现随机答案。我正在使用jquery mobile包含布局。因此,我在div data-roll容器中添加了一个简单的java脚本,并通过$(document).live或$(document).on或$(document).bind初始化它,就像它应该根据这里的许多答案或建议一样。当我使用普通的警报功能时,一切正常。喜欢这个
<script>
$(document).live('pageinit', "#answerPage", function (event) {
alert("Page Initialized");
});
</script>
当我将它添加到普通的html页面时,我的脚本也能正常工作。
所以当我改为使用警报时,我使用函数getanswer()它不起作用。我在这做错了什么?谢谢你的帮助。
