I am using The DynaTree (https://code.google.com/p/dynatree) but I am having some problems and hoping someone can help..
I am displaying the tree on the page like below:
<div id="tree">
<ul>
<li class="folder">Outputs
<ul>
<li id="item1" data="icon: 'base.gif', url: 'page1.htm', target: 'AccessPage'">Item 1 Title
<li id="item2" data="icon: 'base.gif', url: 'page2.htm', target: 'AccessPage'">Item 2 Title
<li id="item3" data="icon: 'base.gif', url: 'page3.htm', target: 'AccessPage'">Item 3 Title
<li id="item4" data="icon: 'base.gif', url: 'page4.htm', target: 'AccessPage'">Item 4 Title
</ul>
</ul>
</div>
However I am trying to change the icon on a item no matter if it's selected or not only using JavaScript.
the new icon I want to use is base2.gif
I have tried using the following but it don't seem to work:
document.getElementById('item1').data = "icon: 'base2.gif', url: 'output.htm', target: 'AccessPage', output: '1'";
anyone know what I might be doing wrong?
Use the setAttribute
method:
document.getElementById('item1').setAttribute('data', "icon: 'base2.gif', url: 'output.htm', target: 'AccessPage', output: '1'");
But you really should be using data followed with a dash and with its property, like:
<li ... data-icon="base.gif" ...>
And to do it in JS use the dataset
property:
document.getElementById('item1').dataset.icon = "base.gif";
