Hi guys!

I need to get the actual value of a field at the moment of typing any value on it. I need a function that should be fire at the moment when the value is changed. I don't mean get the value when the form is saved. I need to get the value of the field "online".

There is any way to do that?

Update:

I have added the following code to my onLoad event

// A namespace defined for the sample code
// As a best practice, you should always define 
// a unique namespace for your libraries
var Sdk = window.Sdk || {};
(function ()
{
    // Code to run in the form OnLoad event
    this.formOnLoad = function (executionContext)
    {        
        var formContext = executionContext.getFormContext();
        var name = formContext.getAttribute("name").getValue();
        var d = window.parent.document.getElementById("name");
        d.oninput = function () { suggest("party", name   d.oninput.arguments[0].data); };

    }

    function suggest(resource, query)
        {
            var API_KEY = "test";
            var xhr = new XMLHttpRequest();
            var serviceUrl = "Url"   resource;
            xhr.open("POST", serviceUrl, true);
            xhr.setRequestHeader("Authorization", "Token "   API_KEY);
            xhr.setRequestHeader("Content-Type", "application/json");
            xhr.onreadystatechange = function () {
                if (xhr.readyState === 4 && xhr.status === 200) {
                    var json = JSON.parse(xhr.responseText);
                    console.log(json);
                }
            };
            var data = "{ \"query\": \""   query   "\" }";
            xhr.send(data);
        }
}).call(Sdk);

I now that this code is unsopported but i can't find a correct solution. With my code i can't get the value of the last input keyword but i cant get the text value that i already typed. Any idea?

I'm using CRM 365 v.9 On premise

Are you talking about onkeypress event ? You can do with Field onchange event.Register a Js function in field onchange event and get the value.

Yes, i'm talking about onkeypress event. As I understand I need to add a code on my OnLoad event, for example

var Sdk = window.Sdk || {}; (function () { // Code to run in the form OnLoad event this.formOnLoad = function (executionContext) { var formContext = executionContext.getFormContext(); formContext.getAttribute("my_fieldname").addOnChange(myFunction); } function myFunction() { //todo } }).call(Sdk);

Am I correct?

Yes this is also work for you , you can also add directly function in the field properties by going to form editor.

I have added directly the function to my field. The function fires when the focus on the field is changed. I need to get the value anytime when I press a keyword.

function myfunc(executionContext){ var formContext = executionContext.getFormContext(); formContext.getAttribute("name").addOnChange(suggest); } function suggest(){ alert("HI"); }
