I tried below code but not works.

a = WebUI.executeJavaScript('document.getElementsByTagName("input")[29].value', null)

Thread.sleep(5000)

System.out.println(a)

There is so much wrong with this question that I don't even know where to begin...

What are you trying to accomplish by using JavaScript (this is a testing code smell, for 99% of testing cases) to fetch a value ?

Why not do the following:

• create a TestObject, preferably in the Object Repository, that points to the object in question.
• give that Test Object the locator. This is, by default, some xpath.

In your case, give it xpath

(//input)[29]

. However, I advise you come up with a more meaningful selector for it (for example, select it by some class, data-* attribute, name) that is easier to maintain

• use the built-in Keyword for getting attribute, like this:

WebUI.getAttribute(findTestObject('[whateverYourTestObjectNameIs]'), 'value')

• this is just good code design, but write this to some Custom Keyword for this util:

// import statements here. Ctrl + Shift + O on your keyboard to bring those in

public final class GeneralWebUIUtils {

    public static final String Value = "value";

    public static final String GetValue(TestObject to) { 
        return WebUI.getAttribute(to, this.Value);
    }
}

Also, why are you pausing runtime by some hard-coded time amount? That is a testing code smell. Stop it!

What exactly are you waiting on? Use the WebUI keywords for this thing you are waiting on, and if none of those suffice, hmu and I may have the wait method you're looking for ....

Oh, and looking at that image you linked, it looks like you solved your own question.
