<pre><code>$('field_name').innerHTML = 'Your text.';

One of the nifty features of Prototype is that <code>$('field_name')</code> does the same thing as <code>document.getElementById('field_name')</code>. Use it! :-)

John Topley's answer using Prototype's <code>update</code> function is another good solution.

blocks|key|1531858|text|快速的答案是使用innerHTML+(或者prototype的更新方法，这几乎是一样的)。innerHTML的问题是你需要避开被赋值的内容。根据您的目标，您将需要使用其他代码或|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1531859|在IE中：|1531860|document.getElementById("field_name").innerText+=+newText;|code-block|syntax|javascript|1531861|在FF中：-|1531862|document.getElementById("field_name").textContent+=+newText;|1531863|(+FF的实际代码中包含以下内容)|1531864|HTMLElement.prototype.__defineGetter__("innerText",+function+()+{+return+this.textContent;+})

The quick answer is to use innerHTML (or prototype's update method which pretty much the same thing). The problem with innerHTML is you need to escape the content being assigned. Depending on your targets you will need to do that with other code OR

in IE:-

<pre><code>document.getElementById("field_name").innerText = newText;
</code></pre>

in FF:-

<pre><code>document.getElementById("field_name").textContent = newText;
</code></pre>

(Actually of FF have the following present in by code)

<pre><code>HTMLElement.prototype.__defineGetter__("innerText", function () { return this.textContent; })

HTMLElement.prototype.__defineSetter__("innerText", function (inputText) { this.textContent = inputText; })
</code></pre>

Now I can just use innerText if you need widest possible browser support then this is not a complete solution but neither is using innerHTML in the raw.

blocks|key|1746924|text|如果您倾向于在站点上开始使用大量的JavaScript，jQuery使使用DOM变得非常简单。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1746925|http://docs.jquery.com/Manipulation|offset|length|1746926|让它变得简单：$(“#field-name”).text(“一些新文本”)；|1746927|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|Z|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@$D|Q|E|R|1|S]]|A|$]]|$1|F|3|G|5|6|7|T|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|U|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|C]]]]

<a href="http://docs.jquery.com/Manipulation" rel="nofollow noreferrer"><a href="http://docs.jquery.com/Manipulation" rel="nofollow noreferrer">http://docs.jquery.com/Manipulation</a></a>

Makes it as simple as:

In HTML put this

I need to set the text within a DIV element dynamically. What is the best, browser safe approach? I have prototypejs and scriptaculous available.

<pre><code>&lt;div id="panel"&gt;
 &lt;div id="field_name"&gt;TEXT GOES HERE&lt;/div&gt;
&lt;/div&gt;

Here's what the function will look like:

<pre><code>function showPanel(fieldName) {
 var fieldNameElement = document.getElementById('field_name');
 //Make replacement here
}
