我有5个寄生虫,我想确认选择了哪个寄生虫。
<p>The 1st paragraph. Hello everyone.Nice meeting you!</p>
<p>The 2nd paragraph. Hello everyone.Nice meeting you!</p>
<p>The 3rd paragraph. Hello everyone.Nice meeting you!</p>
<p>The 4th paragraph. Hello everyone.Nice meeting you!</p>
<p>The 5th paragraph. Hello everyone.Nice meeting you!</p>
JS代码如下:
var para = document.getElementsByTagName('p');
var result = [];
document.onmouseup = function(){
var selectText = window.getSelection();//get the selected range obj,ie9+ support getSelection()
if(selectText.toString()){
for (var i = 0;i<para.length;i++){
if(selectText.containsNode(para[i],true)){
result.push(i+1);//get sequence number of the selected paras
}
}
alert(result);
result = [];
}
}
当我选择这样的文字时:
窗口警报&#34; 1,2,3&#34;,这意味着我选择了第1,第2和第3段。
但是这在IE中不起作用。我搜索了信息,并且知道IE不支持方法containsNode()。如何使containsNode()在IE中工作或使用其他一些方法来获得相同的结果?
PS:选择以下文字时:
为什么它警告&#34; 1,2&#34; ?
