order a section list

michaelc — Fri, 28 Jun 2013 20:40:18 GMT

This should be simple. I am pulling back a list of sections model.sections = context.properties.section.sections; then showing them. <#list sections as section> <a href="${url.context}${section.path}">${section.name}</a> </#list> but I want them in index orde

<#list sections?sort_by("index") as section>

Assuming that your sections structure is [{"index":"index_text", "name":"name_text"}]

Humm.
I tried
<#list sections?sort_by("orderIndex") as section>
and
<#list sections?sort_by("wsrderIndex") as section>

when I dump the values in section I see.
ws:excludeFromNavigation
cm:modified
cmisbjectTypeId
cmis:name
wsarentId
cm:name
type
sys:locale
ws:inheritRenditionConfig
id
cm:description
wsrderIndex
cm:creator
cm:created
cmisbjectId
cm:title
cm:modifier
cmis:lastModificationDate

I see the difficulty. The only defined sort in FreeMarker (that I am aware of) assumes the input array is a JSON structure and yours isn't. At which point you would have to sort sections in Javascript before passing it through to FreeMarker which is simple enough you just need the function to compare the property wsrderIndex.

so it would be something like


function sortSections(s1, s2) {
   return (s1.properties["ws:orderIndex"] > s2.properties["ws:orderIndex"]) ? 1 : (s1.properties["ws:orderIndex"] < s2.properties["ws:orderIndex"]) ? -1 : 0;
}
sections.sort(sortSections);

So based on what you stated I tried.


function sortSections(s1, s2) {
   return (s1.properties["ws:orderIndex"] > s2.properties["ws:orderIndex"]) ? 1 : (s1.properties["ws:orderIndex"] < s2.properties["ws:orderIndex"]) ? -1 : 0;
}

   var sections = context.properties.section.sections;  // Pull the child sections and passthem down.
   sections.sort(sortSections);
‍‍‍‍‍‍‍‍

Failed as sort is undefined.

This does not seem to be Javascript as I know it ( see next note )

but based on that the following did work.


function bubbleSort(a)
{
    var swapped;
    do {
        swapped = false;
        for (var i=0; i < a.length-1; i++) {
            if (a > a[i+1]) {
                var temp = a;
                a = a[i+1];
                a[i+1] = temp;
                swapped = true;
            }
        }
    } while (swapped);
}
 
   var sections = context.properties.section.sections;  // Pull the child sections and passthem down.
   bubbleSort(a);
