我是JQuery&的新手我试图做一些我不确定在JQuery中可以做的事情。
更有经验的JQuery程序员:你如何改进这个尝试将元素更改为textarea的JQuery HTML代码然后又回来了(现在缺少一些功能):
<html>
<head>
<script type="text/javascript" src="jquery-1.6.4.js"></script>
<script type="text/javascript">
<!--
var STATE = 0;
function Toggle()
{
if (STATE==1) { convertToUpdatable(); STATE = 0; }
else { convertToStatic(); STATE = 1; }
}
function convertToUpdatable()
{
// Post: Convert all HTML elements (with the class 'updatable') to textarea HTML elements
// and store their HTML element type in the class attribute
// EG: Before: <p class="updatable"/> Hello this is some text 1 </p>
// After : <textarea class="updatable p"/> Hello this is some text 1 </textarea>
$(".updatable").each(function()
{
$(this).replaceWith("<textarea>"+$(this).text() +"</textarea>");
// TODO store this elements type in class attribute
// The below is guessing that there are jquery functions getType()
$(this).setAttribute( "class", $(this).getAttribute("class") + $(this).getType() );
});
}
function convertToStatic()
{
// Post: Find all HTML elements (with the class 'updatable'), check to see if they are part of another class aswell
// (which will be their original HTML element type) & convert the element back to that original HTML element type
$(".updatable").each(function()
{
// This uses javascript functions: how can I write this in JQuery
var type = this.getAttribute("class").replace("updatable","").replace(" ", "");
if (type == "") { alert("Updatable element had no type defined in class attribute"); return; }
$(this).replaceWith( type +$(this).text() + type );
$(this).setAttribute( "class", "updatable" );
});
}
-->
</script>
</head>
<body>
<p class="updatable"/> Hello this is some text 1 </p>
<b class="updatable"/> Hello this is some text 2 </b>
<i class="updatable"/> Hello this is some text 3 </i>
<input id="MyButton" type="button" value="Click me!" onclick="Toggle();" />
</body>
</html>

使用Javascript:
your_element.className = 'some_class';
your_element.nodeName;
