ajax格式,(key:value,)value值用单引号括起来
$.ajax({
type:,//'post','get'
url:,//action的路径
data:,//传到后台的参数,多个参数的连接符为'&'
success:function(msg){}//对返回的JSP页面或结果进行处理
});
1)jsp:
<tdstyle="width:155px;"> <inputtype="text"name="sn"id="sn"onkeyup="getsn()"value="${sn}"autocomplete="off"/> </td>
<tdstyle="width:155px;">
<%--<divid="div_sn"style="position:absolute;left:150;top:10;z-index:0;width:155px;"></div>--%> <divid="div_sn"style="width:155px;"></div> </td>
2)Javascript:
data的值表示把页面的值传到后台(/GetSN.action),多个参数的连接符为'&'
执行成功后把结果放到一个JSP页面(ajaxSN.jsp),通过success:function(msg),放到ID为'div_sn'
functiongetsn(){ document.getElementById("div_sn").style.display="block"; varsn=$('#sn').val(); varproduct=$('#product').val(); if(sn.length>5){ $.ajax({ type:'post', /GetSN.action'" rel="nofollow" target="_blank">url:'<%=request.getContextPath()%>/GetSN.action', timeout:2000, data:'sn='+$('#sn').val()+'&product='+$('#product').val(), success:function(msg){ $("#div_sn").html(msg); } }); } }
3)ajaxSN.jsp
