Question

my function look like this:

 void write (String message) {
    query("#status").innerHTML = message;
    query("#head").text = "Click me!";

  }

all of them catch id and show text to web browser.

Answer 1

In general browser document model, innerHtml refers to all the internal HTML, whereas text just refers to the text values of the elements. innerHtml is often used by dhtml and Ajax to change a div, where text would be just to set the text value of a single element.

This is more explicitly illustrated when getting, rather than setting, i.e.

e.g. Given:

<div id="idName">
    Text in the Div
    <p id="anotherId">Inner P</p>
</div>

innerHtml returns

Text in the Div 
<p id="anotherId">Inner P</p>

text returns :

Text in the Div 
Inner P
