    <p>I have an array of nested object (I use this to populate my tree), something like below..</p> <pre><code>var obj1= { text: "TreeRoot", items: [ { text: "subgroup1" , items: [ { text: "subgroup2", items: [ { text: "subgroup3", items: [ { text: "subgroup4", items: [ { text: "subgroup5" }] }] }] }] }] }; var obj2 = { text: "TreeRoot", items: [ { text: "subgroup1" , items: [ { text: "subgroup2", items: [ { text: "subgroup3", items: [ { text: "subgroup4", items: [ { text: "subgroup5" }] }] }] }] }] }; var obj3= { text: "TreeRoot", items: [ { text: "subgroup1" , items: [ { text: "subgroup2" }] }] }] }; var finalArray=[]; finalArray.push(obj1); finalArray.push(obj2); finalArray.push(obj3); </code></pre> <p>Now I need to remove the duplicate objects from my final array using text(i.e I should remove obj2 from my array)...</p> <p>This is what I tried..</p> <pre><code>var arr = {}; for ( var i=0; i &lt; finalPath.length; i++ ) arr[finalArray[i]['text']] = finalArray[i]; finalArray= new Array(); for ( key in arr ) finalArray.push(arr[key]); </code></pre> <p>Can someone let me know the best possible way?</p> <p>Edit:</p> <p>I think the below solution works, but yet to test it completely...</p> <pre><code>var arr = {}; for ( var i=0; i &lt; finalArray.length; i++ ){ if(finalArray[i].items){ for(var j=0;j&lt;finalArray[i].items.length;j++){ arr[finalArray[i].items[j]['text']] = finalArray[i]; } }else{ arr[finalArray[i]['text']] = finalArray[i]; } } finalArray= new Array(); for ( key in arr ) finalArray.push(arr[key]) </code></pre> <p>Thanks, Barani</p>

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.
