嗨,我已经使用 contentEditable 有一段时间了,我认为我对它有很好的掌握。回避我的一件事是如何获取对部分或完全在用户选择范围内的所有节点的引用数组。有人有想法吗?
可以从以下几点开始:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript">
function getSelectedNodes(){
var sel = window.getSelection();
try{var frag=sel.getRangeAt(0).cloneContents()}catch(e){return(false);}
var tempspan = document.createElement("span");
tempspan.appendChild(frag);
var selnodes = Array() //<<- how do I fill this array??
var output = ''
for(i in selnodes){
output += "A "+selnodes[i].tagName+" was found\n"
//do something cool with each element here...
}
return(output)
}
</script>
</head>
<body contentEditable="true" onkeypress="return(keypress(event))">
<div>This <strong>div</strong> is <em>content</em> <span class='red'>editable</span> and has a couple of <em><strong>child nodes</strong></em> within it</div>
<br />
<br />
<a href="#" onmouseover="alert(getSelectedNodes())">hover here</a>
</body>
</html>
