[英]Ajax call pass parameters to function
What is wrong with this code? 此代码有什么问题? I am trying to pass parameters to a WCF function.
我正在尝试将参数传递给WCF函数。 I couldn't get this to work.
我无法使它正常工作。 I am getting Ajax error.
我收到Ajax错误。
$.ajax({
url: applicationPath + "/Test.svc/GetData",
type: "POST",
dataType: "json",
data: '{GId":' + sender.get_value() + '"GName":' + sender.get_text() + '"mId":' + testId + '}',
contentType: "application/json; charset=utf-8",
success: function(result)
{
//trying to fill combobox here
},
});
The data is not valid JSON. 数据无效的JSON。 What follows is the code and an example of its result.
以下是代码及其结果示例。
'{GId":' + sender.get_value() + '"GName":' + sender.get_text() + '"mId":' + testId + '}'
>> '{GId":'foo'"GName":'bar'"mId":5}'
Instead of constructing JSON manually, I would use JSON.stringify
and pass it an object. 我将使用
JSON.stringify
并将其传递给一个对象,而不是手动构造JSON。
JSON.stringify({GId: sender.get_value(), GName: sender.get_text(), mId: testid})
>> "{"GId":"df","GName":"sdf","mId":4}"
I think you can see there is a difference. 我认为您可以看到有所不同。 Your code was missing commas and a quotation mark at the beginning of
GId
. 您的代码缺少逗号和
GId
开头的GId
。
