jQuery 代码没有正确显示函数。什么都没有发生。
<script type="text/javascript" src="/student/common/scripts/jquery.min.js">
</script>
<script type="text/javascript">
$(document.ready(function(){
$("#Div1").click(function(){$("#Div1").css("font-size","40px")});
$("#Div2").click(function(){$(this)
.css({"background":"crimson","color":"blue"})
$("#Div3").click(function(){$("div").css("background":"beige");});
$("#Div4").click(function(){${(this_.hide();});
$("#Div5").mouseover(function(){$(#Div4").show();});
});
</script>
