我做了一个网络方法,我试图通过javascript调用,但它似乎没有被解雇。我从usercontrol中的列表框中抓取所选索引值,并将其传递给我的webmethod以删除所选用户。我看过无数的网站,但没有找到解决方案。我没有收到任何错误,其他一切似乎都有效。我已经尝试从后面的代码中的公共子调用此函数也没有运气。非常感谢任何建议!

我认为您应该使用JSon
来调用Web方法,这里是简单的示例
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "yourpage.aspx/yourmethod",
data: "{}",
dataType: "json",
success: function(data) {
//Write functionality to display data
},
error: function(result) {
alert("Error");
}
});
