1. Create a hidden Input in your screen (it can be a text box) and give it a name (eg. NameInput);
2. Bind the OutSystems local variable NameOS to the NameInput;
3. Make sure that your Javascript logic writes the value of the NameJS Javascript variable to the NameInput (remember that you have the OutSystems runtime property NameInput.Id in your input that gives you the DOM Id of the OutSystems input in runtime so that you can use it in your Javascript logic);
4. Once the form is submitted to the server (with a button or link), you will have available the NameInput value available in the NameOS local variable. As your javascript logic is writing the NameJS value to the NameInput, this means you will have have achieved your goal - the NameOS variable is holding the value of the NameJS variable.

"var r = confirm(""Text"");
if (r == true) {
    " + Input.Id + ".value = 1;
} else {
    " + Input.Id + ".value = 0;
}"

Hi,

I'm trying to use this logic to get a random number to be passed into a web service and the page be refreshed by Javascript. I can do it through Ajax refresh but the Javascript bit is tricky.

I am able to output the random numbers into text boxes by Javascript, however I am only able to show them not manipulate them.

I've tried passing the typed value into a function (which simply doubles it).

My random number is put into a text input box by this javascript.

I imagine I am doing something really daft, as this article did make a lot of sense, and helped me get started. However, I have reached a bit of a roadblock. Any ideas?

        document.getElementById("RichWidgets_wt3_block_wtMainContent_wtLatestRandomNumber").value = answer;

I have this in my onclick of a navigate button (which goes to "#") for the External URL

SyntaxEditor Code Snippet

"document.getElementById('" + Average1.Id + "').value = '"+DoubleMe("document.getElementById('"+LatestRandomNumber.Id+"').value")+"';"

In case you want an example, I had to pass a Javascript variable into an application variable to verify that the user clicks the "I am not a Robot" captcha.

This module is dependent on the New reCAPTCHA.
Disclaimer: This module does not properly/securely verify the captcha click. It uses a workaround, grecaptcha.getResponse().

Hi Everyone,

Can someone point me to a post wherein the Local Variable of a Web Screen can be used in a Javascript (with sample code).

Thank you and regards,

Christopher

function addTwoJavascriptfields(id1, id2, id3, id4)

{
    var fieldOne = document.getElementById(id1).value; //gets from Input
    var fieldTwo = document.getElementById(id2).value; //gets from Input
    var sum = parseInt(fieldOne) + parseInt(fieldTwo);
    document.getElementById(id3).value = sum; //places in an Input box
    document.getElementById(id4).innerHTML=sum; //places in an expression
}

This Outsystems platform promises "fast quick build application time" when passing a Javascript function return object/variable to an outsystem local variables takes you days to figure out which the "normal way of programming" can do straightforwardly in minutes. I wonder how many skeletons in Outystem's closet is still hiding.

I agree, it's not obvious or straightforwards... but it does NOT take "days to figure out", especially when sample code abounds in the forums and forge, and there are plenty of people (myself included) who would be happy to spend a few minutes on a screenshare showing you how to do it.
