Good day
I have a PHP site and I use JAVA graphs. The graph work as long as the data come from a browser code for that is the only way to add data to a JAVA script in Webdev. If I populate an array of data from my Code from MySQL data I cannot push it to the Browser Procedure array. Is there any other way?
Regards

Hi Ruan,
Well, if you are using a JS graph, you HAVE to talk to it in JS...
However, nothing prevents you from preparing the data in server code, then send it to the browser side several ways.
By example, you can call the server side with ajaxexecute, and get the result as a string. You then use the content of the string to call you JS graph.

Hi Fabrice
Thanks for our assistance but I cannot get the ajaxexecute to work in the JS Browser code.
Is there any examples anywhere where I can see how this is done in Webdev 22?
Regards

Hi Fabrice
I have tested the ajaxexecute function and worked to return a string from the server code. I am working with a graph and I am trying to return an array of int. The server side creates the array 100% but it seems that it doesn't pull through to Browser code or JS.
This is Server Code with Ajax ON:
Procedure MyGraphGata()
arrLines is array of int arrLines = [1,2,3,4,5,6]
RESULT arrLines
This is Browser Code:
Procedure Var()
IsArray is array of int
IsArray = AJAXExecute(MyGraphGata)
RESULT IsArray
This is the JAVA Script:
function LoadChart(loader) { var ctx = document.getElementById("myChart").getContext('2d'); var myChart = new Chart(ctx, { type: 'bar', data: { labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"], datasets: [{ label: '# of Votes', data: loader, backgroundColor: [ 'rgba(255, 99, 132, 0.2)', 'rgba(54, 162, 235, 0.2)', 'rgba(255, 206, 86, 0.2)', 'rgba(75, 192, 192, 0.2)', 'rgba(153, 102, 255, 0.2)', 'rgba(255, 159, 64, 0.2)' ], borderColor: [ 'rgba(255,99,132,1)', 'rgba(54, 162, 235, 1)', 'rgba(255, 206, 86, 1)', 'rgba(75, 192, 192, 1)', 'rgba(153, 102, 255, 1)', 'rgba(255, 159, 64, 1)' ], borderWidth: 1 }] }, options: { scales: { yAxes: [{ ticks: { beginAtZero:true } }] } } });}
And This is the Call from button click with JS switched on and not WL:
LoadChart(Var());
Am I missing something? Why does is not return the Arra?
Thanks

Hi
as indicated in the help, the ajaxecute functions returns a STRING. Therefore you need to transform the array into a string BEFORE sending it back to the browser, and you need to manage the content of the string on the browser side.
