basketInfo != BasketInfo

Ammar Al-hamdabni 21-Sep-15 3:38am

sorry i didn't understand

You should take into consideration that parameters in web method are case sensitive.basketInfo != BasketInfo.

Ammar Al-hamdabni 21-Sep-15 4:00am

I changed basketInfo to Info, but doesn't work

Naveen.Sanagasetti 21-Sep-15 3:44am

I request you to please search the URL in browser, if it is working fine, then please check the parameters which you passed through Json call, I guess this is case sensitive, as Point out by Rohan Leuva, in method declaration you are using the parameter "BasketInfo" and in JSON call you call like below "basketInfo", I guess this might be problem, Please check this once.

Ammar Al-hamdabni 21-Sep-15 3:56am

it doesn't appear in URL

Naveen.Sanagasetti 21-Sep-15 4:07am

Call the Service URL and open the method which you try to call using JSON.

Ammar Al-hamdabni 21-Sep-15 4:14am

the mothod which I made it didn't appear in service

Naveen.Sanagasetti 21-Sep-15 5:23am

That is the reason it is throwing that error, As per Solution 1 if you remove static it will show that method in service call, obviously it should work as you expected.

see your webserver errorlog or database errorlog for the cause of this HTTP 500 error

You are right, It appear now, but still give me error to insert data

vagelis1 21-Sep-15 5:01am

please post your error message

vagelis1 21-Sep-15 5:25am

in your question you set
Items= "some thing"
on server side you do
string[] Allitems = item.Split('_');
string itemValue = Allitems[0];
string itemID = Allitems[1];

SO Allitems[1] will throw indexoutofrange exception as item.Split('_') will return only one element in Allitems

Ammar Al-hamdabni 21-Sep-15 6:15am

sorry, I mean in 'Some thing' there is a value that give me from another page.

the error always show me this message:
'Failed to load resource: the server responded with a status of 500 (Internal Server Error)'

You should try debuging InsertMethod on the server side. Something raises exception there.
