How can I sort an array, yet exclude certain elements (to be kept at the same position in the array)
- by calumbrodie
This will be implemented in Javascript (jQuery) but I suppose the method could be used in any language.
I have an array of items and I need to perform a sort. However there are some items in the array that have to be kept in the same position (same index).
The array in question is build from a list of <li> elements and I'm using .data() values attached to the list item as the value on which to sort.
What approach would be best here?
<ul id="fruit">
<li class="stay">bananas</li>
<li>oranges</li>
<li>pears</li>
<li>apples</li>
<li class="stay">grapes</li>
<li>pineapples</li>
</ul>
<script type="text/javascript">
var sugarcontent = new Array('32','21','11','45','8','99');
$('#fruit li').each(function(i,e){
$(this).data(sugarcontent[i]);
})
</script>
I want the list sorted with the following result...
<ul id="fruit">
<li class="stay">bananas</li> <!-- score = 32 -->
<li>pineapples</li> <!-- score = 99 -->
<li>apples</li> <!-- score = 45 -->
<li>oranges</li> <!-- score = 21 -->
<li class="stay">grapes</li> <!-- score = 8 -->
<li>pears</li> <!-- score = 11 -->
</ul>
Thanks!
