    <p>I am attempting to split a string of integers into an array in JavaScript.</p> <p>Originally I had: </p> <pre><code>m.rows[7] = new Array (8,11); </code></pre> <p>And I am changing it to: </p> <pre><code>var nearby = nearby.split(","); m.rows[7] = new Array (nearby); </code></pre> <p>(And setting a variable with the appropriate integers separated by a comma in my level editor. When I print "nearby[0]" to the console I get '8'. When I print "nearby[1]" to the console I get 11)</p> <p>However, I then have this code in which I attempt to match one of the elements in the array with an element in another array:</p> <pre><code> for (var i = m.rows[id].length-1; i &gt;= 0; i--) { // If the loop finds an element ID that matches the ID of the last element in the path array, do this: console.log('test nearby 2: ' + m.rows[id][i]); if (m.rows[id][i] == this.path_array[this.path_array.length-1].id) { // Loop through the one array for (var j = all_nodes.length-1; j &gt;= 0; j--){ // If the ID of one of one of these entities matches the id of the instance that was just clicked if (all_nodes[j].id == id) { // Activate that node: all_nodes[j].active = true; } } break; } </code></pre> <p>When I actually put "8,11" into the array above manually the above works perfectly. However when I attempt to use "nearby" which I split into the array, it does not. And printing it to the console in "test nearby 2" above, when I use "nearby" "8,11" gets printed. When I manually enter "8,11" into that array I get "11". </p> <p>I'm fairly new to JavaScript so I'm probably missing something extremely obvious here - can anyone shed some light? </p> <p>Thanks!</p>

    1. COIt's unclear what `nearby` actually is; is it a string with comma-separated values? If so, note that splitting it will result in strings, not actual `Number`s. That *may* be okay, because JS will do type conversion, but it depends on the order of operations. Easier/safer to just make them numbers after the split.

    2. CODave, Nearby was a string with comma-separated values as you suggest. Minitech's answer below ended up helping me do what I was attempting :)

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.
