Question

我尝试将参数传递给我的Web服务并在文本框中显示结果。我的Web服务正在运行。我在浏览器中调用了方法......我认为我的Jquery出了问题。

我做错了什么？谢谢你的帮助

Answer 1

'data'应该是一个对象而不是JSON字符串：

data: { "PanelID": PanelIDs }

Answer 2

数据：“{'PanelID'：'”+ PanelIDs +“'}”应为数据：“{'PanelIDs'：'”+ PanelIDs +“'}”

凯伊需要匹配属性名称

Answer 3

首先测试您的网络服务网址和网络服务的方法应该是公开的和你的网络服务网址，如你的网络方法

      url: "www.entwicklung.de/Web/Service1.asmx/getDatetime",

Answer 4

您可以调整data - PanelID (with s in the end)

data: "{ 'PanelIDs': '" + PanelIDs + "' }"

从Ajax传递参数到Web服务
