Hi Safi,

To rule out the possibility of the user error in your code, any chance you could run any of the JS examples included into the Backendless SDK for JavaScript? Make sure to include your application ID and secret key into the code (you can find the instructions in the getting-started documented which is also included into the SDK zip).

Regards,
Mark

Hi Mark,
first of all thank you with the help of you I get the output .
now i am trying to display the value retrieved from backendless to html form elements like textbox or label.
but i can’t get that value in any control.
i can print the value or alert the value but unable to display in any control.
to display in control i am using following code

//html code

Diesel Price:-<input type="text" name="Diesel" />

/*java script code*/
document.getElementsByName('Diesel').value=JSON.stringify(krishPrice['data'][0]['Diesel']);

one more thing that how can i show that values in numeric format without quotation.?
so please give me the solution regarding this issue.
and also can you give me your mail id so that i can contact you.
I am a web developer at AKH infotech.

Hi Safi,

Your question is entirely on the client-side programming and not related to Backendless at all. We typically do not provide support for pure client-side issues. You might want to ask this question on a jQuery or a JavaScript-programming related forum.

Couple of links that might help you:
