jquery $.getJSON 在asp.net中的用法例子
下面是asp.net页面test.aspx <script type="text/jscript" src="../js/jquery-
1.2.5.js"></script>
<script type="text/javascript">
//获取对象列表
$(function(){
$.getJSON("Handler.ashx",function(json){
$.each(json.data,function(i)
{$('#content').append("姓名："+json.data.name+"----性
别："+json.data.avg+"----时间："+json.data.year
+"<br/>");});
});
});
</script>
<script type="text/jscript" src="../js/jquery-
1.2.5.js"></script>
<script type="text/javascript">
//获取一个对象
function checkServer() {
$.getJSON("AjaxGetService.aspx?planNo=" +
$("#txtPlanNo").val(), function(data) {
// alert(data.toString());
// alert(data.IsTrustee);
if (data.IsTrustee==true) {
$("#cheTrustee").attr("checked", true);
}
else {
$("#cheTrustee").attr("checked",'');
}
if (data.IsAccount == true) {
$("#cheAccount").attr("checked", true);
}
else {
$("#cheAccount").attr("checked", '');
}
// alert(data.CityName); ,
{planNo:$("#txtPlanNo").val()}
});
}
</script>
