How can I transfer data from a C# code to a JavaScript file in asp.net?

I am faced with the task of transferring values from a C# class to a JavaScript file. To achieve this, I have generated a string in C# which contains the values of the list as follows:

count = 0;
JString = "[";
for(i=0; i<x; i++)
{
    JString += "{Source:" + A[i] + ", Number:" + 3 + ", Target:" + B[i] + "},";
    count++;
}
JString = JString.Remove(JString.Length - 1, 1); //to eliminate the last ,
JString += "]";
GraphData.Text = "" + "var JString =" + JString + " ;" + "var count =" + count + " ;";

The GraphData label is utilized to store the created string.

In the JavaScript file, an attempt was made to retrieve the sent string using the following code snippet:

 $("#GraphData").val(); //to get the string sent

However, it seems like this approach is not functioning correctly. Could there be something wrong with how I'm implementing it?

I appreciate any insights or guidance on this matter. Thank you in advance :)

Answer №1

for(index=0; index<total; index++)
{
    ResultString += "{Start:" + X[index] + ", Value:" + 5 + ", End:" + Y[index] + "},";
    total++;
}

It seems like there is a potential infinite loop here. By incrementing both index and total inside the loop, index will always be less than total

Answer №2

Once you have resolved the issue of the infinite loop, make sure to utilize $('#GraphData').text(); since in asp.net, the Label is displayed as a span element.

Answer №3

It seems like GraphData is being utilized as a server control here. The element can be accessed by using its ClientID.

Here's a suggestion to retrieve the value:

$("# <%= GraphData.ClientID%> ").val();
