    <p>I have an array that keep the data in tree structure but I'd like to transform this data to json. This is the example of my data :</p> <pre><code>[Object] 0: Object children: Array[1] 0: Object children: Array[1] 0: Object children: Array[10] 0: Object children: Array[6] value: Object 1: Object 2: Object 3: Object 4: Object 5: Object 6: Object 7: Object 8: Object 9: Object value: Object Id: "00145E5BB2641EE284F811A7907757A3" Parent: "00145E5BB2641EE284F811A7907737A3" Ref: undefined Text: "Functional Areas" Type: "TWB" </code></pre> <p>Now I want to transform these array of data to Json. I tried JSON.stringify(myArray); but the format isn't correct. It destroys all structure of tree. Any ideas?</p> <p>This is the code that give the result above.</p> <pre><code>function transformToStruct(xmlData, callback) { var data = xmlData.item; var roots=[]; var children = {}; var arry=createStructure(data); // find the top level nodes and hash the children based on parent for (var i = 0, len = arry.length; i &lt; len; ++i) { var item = arry[i], p = item.Parent, target = []; if(p == rootId) { target = roots; } else { target = (children[p] || (children[p] = [])); } target.push({ value: item }); } // function to recursively build the tree var findChildren = function(parent) { if (children[parent.value.Id]) { parent.children = children[parent.value.Id]; for (var i = 0, len = parent.children.length; i &lt; len; ++i) { findChildren(parent.children[i]); } } }; // enumerate through to handle the case where there are multiple roots for (var i = 0, len = roots.length; i &lt; len; ++i) { findChildren(roots[i]); } // var returnV = JSON.stringify(roots); // callback(returnV); callback(roots) } function createStructure(data) { var arry = []; $.each(data, function(i, val) { var parent = val["ParentId"]["#text"]; var id = val["NodeId"]["#text"]; var text = val["NodeText"]["#text"]; var level = val["NodeLevel"]["#text"]; var ref = val["RefObject"]["#text"]; var type = (val["NodeType"]["#text"]).substring(0,3); if(level == "01") rootId = parent; var item = {"Id": id, "Text": text, "Parent": parent, "Type" : type, "Ref" : ref}; arry[i] = item; // arry.push(item); }); console.log(arry) return arry; } </code></pre>

    2. COIs this a copy and paste of your tree object? If so, you get the format isn't correct message cause it's not correct.

    3. COI would like to see the native JavaScript Code of your object or just print it to the console log and paste it over here. the above is pseudo code but the prob seems to be the real code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
