Internet Explorer问题 - 参数的Web服务调用缺失值无效 [英] Internet Explorer Issue - Invalid web service call missing value for parameter

问题描述

我有一个网络方法：

I have a webmethod:

<WebMethod(Description:="getProductDescription",)> _
<ScriptMethod(ResponseFormat:=ResponseFormat.Json)> _
    Public Function getProductDescription(ByVal sellReqID As Integer) As Object

    End Function

我正在使用的是：

Which I am calling using:

$.ajax({
                    type: "POST",
                    contentType: "application/json; charset=utf-8",
                    url: "Haggler.asmx/getProductDescription",
                    dataType: 'json',
                    async: false,
                    data: '{sellReqID:"' + getQueryVariable("sellReqID") + '"}', // Page parameter to make sure we load new data

                    success: function (data) {
//do something on success here

     },
                    error: function (result) {
                        alert(JSON.stringify(result));
                        return flag;
                    }
                });

我从查询字符串中获取sellReqID的值javascript函数如下：

I am getting the value of the "sellReqID" from the querystring using a javascript function as follows:

// get value of querystring
        function getQueryVariable(variable) {
            var query = window.location.search.substring(1);
            var vars = query.split("&");
            for (var i = 0; i < vars.length; i++) {
                var pair = vars[i].split("=");
                if (pair[0] == variable) {
                    return pair[1];
                }
            }
            return (false);
        }

现在奇怪的是，这在所有浏览器中工作正常除了IE 说



无效的网络服务电话，参数缺失值\\\\'sellReqID \\\\ 0000



当我尝试在 Internet Explorer 上运行它时。



请帮我弄清楚实际原因对于这个问题，并指出我的解决方案。任何帮助表示赞赏。

更新：如果我删除来自AJAX调用的参数它开始在IE上工作。

Now strangely, this is working fine in all the browsers except IE while it says

Invalid web service call, missing value for parameter \\u0027sellReqID\\u0027

when i try to run it on Internet Explorer.

Please help me figure out the actual reason for the issue and point me towards a solution. Any help is appreciated.

推荐答案

.ajax（{
type： POST，
contentType： application / json; charset = utf-8，
url： Haggler.asmx / getProductDescription，
dataType：' json'，
async： false ，
data：' {sellReqID：' + getQueryVariable（ sellReqID）+ ' } ， // 页面参数，以确保我们加载新数据

成功：功能（数据）{
// 在这里取得成功

}，
错误： function （结果）{
alert（ JSON .stringify（result））;
返回标志;
}
}）;

.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "Haggler.asmx/getProductDescription", dataType: 'json', async: false, data: '{sellReqID:"' + getQueryVariable("sellReqID") + '"}', // Page parameter to make sure we load new data success: function (data) { //do something on success here }, error: function (result) { alert(JSON.stringify(result)); return flag; } });

如果服务期望一个诸如整数的原语，你不必将值包装在''''中，可能只是一个脑屁。至于获取值，我会创建一个var和parseInt它。您应该首先提醒数据值并在JSON验证器上运行它，我可能会得到逗号错误。

If the service is expecting a primitive such as integer, you don''t have to wrap the value in '''', probably just a brain fart. As far as getting the value goes, I would create a var and parseInt it. You should alert the data value and run it on a JSON validator first, I may of gotten the comma''s wrong.

data: ''{sellReqID:"'' + getQueryVariable("sellReqID") + ''"}'',

var sellReqID = parseInt(getQueryVariable("sellReqID"));

alert("{\""sellReqID:\""" + sellRegID + "}");

data: "{\""sellReqID:\""" + sellRegID + "}";
