在元素后插入html代码

Question

I have a html document which looks like this:

...html code...
<ul id="my_ul">
...html code...

Using javascript I want to insert the html code below inside the document, immediately after <ul id="my_ul"> :

<li><span>Some text</span><ul>

So far I have this, but not the expected results. Please, what am I doing wrong?

var para1 = document.createElement("li");
var para2 = document.createElement("span");
var node = document.createTextNode("Some text");
para2.appendChild(node);
var para3 = document.createElement("ul");
var element = document.getElementById("my_ul");
element.appendChild(para1);
element.appendChild(para2);
element.appendChild(para3);

Answer 1

Like this:

 var ul = document.getElementById("my_ul"); var li = document.createElement("li"); var span = document.createElement("span"); var text = document.createTextNode("Some text"); span.appendChild(text); li.appendChild(span); ul.appendChild(li); 

 <ul id="my_ul"> </ul> 

Answer 2

If you want shorter code without creating objects for each html elements just do this:

var element = document.getElementById("my_ul");
var html = '<li><span>Some text</span></li>'; 
element.innerHTML = html + element.innerHTML;

Answer 3

Is this what you want to do?

Demo: Fiddle

var para1 = document.createElement("li");
var para2 = document.createElement("span");
var node = document.createTextNode("Some text");
para2.appendChild(node);
para1.appendChild(para2);
element = document.getElementById("my_ul");
element.appendChild(para1);

Answer 4

Your code does this:

 element.appendChild(para1); 

Make the list item a child of the original list

 element.appendChild(para2); 

Make the span a child of the original list

 element.appendChild(para3); 

Make the new list a child of the original list

---

You need to append each element to the element you want to be its parent instead of appending everything to the original list.

Replace element with the appropriate variable.

 $(document).ready(function(){ var para1 = document.createElement("li"); var para2 = document.createElement("span"); var node = document.createTextNode("Some text"); para2.appendChild(node); var element = document.getElementById("my_ul"); element.appendChild(para1); para1.appendChild(para2); });

var ul = document.getElementById("my_ul");
var li = document.createElement("li");
var span = document.createElement("span");
var textNode = document.createTextNode("Some text");
span.appendChild(textNode);
li.appendChild(span);
ul.appendChild(li);
