    <p><strong>Updated</strong></p> <p>To search in the array with Vanilla js I would use the <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter" rel="nofollow noreferrer"><code>filter()</code></a> method implemented into the Array prototype</p> <h3>Hacker style</h3> <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false"> <div class="snippet-code"> <pre class="snippet-code-js lang-js prettyprint-override"><code>let a = ["foo","fool","cool","god"]; let b = a.filter(item =&gt; item.indexOf('oo') &gt; -1); console.log(b); // ["foo","fool","cool"]</code></pre> </div> </div> </p> <h3>ES6 style (ES2015)</h3> <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false"> <div class="snippet-code"> <pre class="snippet-code-js lang-js prettyprint-override"><code>const fruits = ['apple', 'banana', 'grapes', 'mango', 'orange']; const filterItems = (needle, heystack) =&gt; { let query = needle.toLowerCase(); return heystack.filter(item =&gt; item.toLowerCase().indexOf(needle) &gt;= 0); } console.log(filterItems('ap', fruits)); // ['apple', 'grapes'] console.log(filterItems('ang', fruits)); // ['mango', 'orange']</code></pre> </div> </div> </p> <h3>ES5 style</h3> <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false"> <div class="snippet-code"> <pre class="snippet-code-js lang-js prettyprint-override"><code>var fruits = ['apple', 'banana', 'grapes', 'mango', 'orange']; function filterItems(needle, heystack) { var query = needle.toLowerCase(); return heystack.filter(function(item) { return item.toLowerCase().indexOf(query) &gt;= 0; }) } console.log(filterItems('ap', fruits)); // ['apple', 'grapes'] console.log(filterItems('ang', fruits)); // ['mango', 'orange']</code></pre> </div> </div> </p> <hr> <p><em>This is the outdated answer</em></p> <p>To search in the array with jQuery you might use <code>jQuery.grep()</code> or <code>jQuery.map()</code>. Both return new array with filtered elements using a callback function.</p> <p>The fastest implementation (case insensitive) is using <code>indexOf</code> and <code>toUpperCase</code> in the callback:</p> <pre><code>var search_term = 'oo'; // your search term as string var search = search_term.toUpperCase(); var array = jQuery.grep(a, function(value) { return value.toUpperCase().indexOf(search) &gt;= 0; }); </code></pre> <p><em>If you don't need case insensitive search you can remove both <code>.toUpperCase()</code> to speed it up even further.</em></p> <p>More flexible but much slower (good enough for small arrays) is to use regular expression:</p> <pre><code>var search_term = "oo"; // search term var search = new RegExp(search_term , "i"); var arr = jQuery.grep(a, function (value) { return search.test(value); }); </code></pre> <p>or</p> <pre><code>var search_term = "oo"; // search term var search = new RegExp(search_term , "i"); var arr = jQuery.map(a, function (value) { return value.match(search) ? value : null; }); </code></pre> <p><em>Regular expressions allow you to make searches much more complex than <code>%value%</code>. However don't use it if you don't need it because it is many times slower.</em></p> <p>you should get an array <code>arr</code> with the matched elements</p>

    1. COhow to pass variable instead of "oo" on search = /oo/gi; Is that like search = /my_var/gi; ?

    2. COshould use `search = new RegExp(my_var, "gi");` /oo/gi is a shortcut of `new RegExp("oo","gi");` but be aware that `$.grep` and `$.map` cannot have extra params, so your `my_var` have to be defined in the global scope, which is not a good practice, but don't see other simple way

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.
