Question

I have a generic function to get data and disable an another HTML tag :

function Testing(htmlData, htmlResult) {
    //here I'd like get the value of htmldata (it's a tag name)
}

I call this function like this :

<input type="text" id="MyTextBox" />
<input type="text" id="MyTextBoxResult" />
$("#MyTextBox").blur(function () {
    Testing("MyTextBox", "MyTextBoxResult");
});

Answer 1

function Testing(htmlData, htmlResult) {
    var valueOfHtmlData = $('#' + htmlData).val();
}

But you could also pass the jQuery object directly to your function

$("#MyTextBox").blur(function () {
    Testing($(this), "MyTextBoxResult");
});

and your function would be

function Testing(htmlData, htmlResult) {
    var valueOfHtmlData = htmlData.val();
}
