Retrieving User Input using ArcGIS API for JavaScript?

Question

I am using the ArcGIS API for JavaScript to build a web application. Within the web app a geoprocessing service is executed which requires an input that is user dependent.

I thought of a text box where the user can enter a value, which should then be read by the application and used for the geoprocessing service.

How can this be done? I searched on the ArcGIS API website and in the Internet, but I could not find any solution so far.

You can do this easily with some HTML by using a text box somewhere in your page or in a modal window:

<input type="text" id="out-folder">

And then for the params of your GP Service in JavaScript:

// set up params
var gpParams = {
 "Boundary": fs,
 "Layer_URL": dom.byId("layer-choice").value,
 "Output_Folder_Name": dom.byId("out-folder").value, //var from text box is here
 "Include_Features": dom.byId("include-features").checked
}

In my example, I'm using the dojo.dom to get the textbox value, but you can also do this with standard JavaScript like this:

document.getElementById("out-folder").value

I have some very basic examples of using GP services with the JavaScript API here.
