    <p>I'm trying to create a javascript function that accepts 2 parameters <code>min</code> and <code>max</code> and generates a random number between the two integers. That part is easy.</p> <p>Where things get rough is that I need to create a conditional that says </p> <pre><code>function generateNum (min, max) { var randNumber = Math.ceil(Math.random()*(max - min)+min); if (randNumber === max) { // store the result (probably in an array) and generate a new // number with the same behavior as randNumber (e.g. it is also // stores it's total in the array and recursively "re-generates // a new number until max is not hit) } } </code></pre> <p>The idea is to recursive-ise this so that a running total of the number of max hits is stored, combined, and then returned.</p> <p>For example: The script receives min / max parameters of 5/10 <code>generateNum(5,10){}</code>. If the value generated by <code>randNumber</code> were 5, 6, 7, 8, or 9 then there would be no recursion and the function would return that value. If the value generated by <code>randNumber</code> is <code>10</code>, then the value <code>10</code> is stored in an array and the function now "re-tries" recursively (meaning that as many times as 10 is generated, then that value is stored as an additional object in the array and the function re-tries). When the process stops (which could be infinite but has a parabolically decreasing probability of repeating with each recursion). The final number (5, 6, 7, 8, 9) would be added to the total of generated <code>max</code> values and the result would be returned.</p> <p>Quite an unusual mathematic scenario, let me know how I can clarify if that doesn't make sense.</p>

    1. COSo what is the "stop" condition and what is the "recurse" condition? Just write that in the code as described.

    2. CODon't understand why you need recursion. Just use a `while` loop and a counter which you increment whenever you get `max`. Stop once you get a different number. The result is then `counter * max + randNumber` (or if you want to return an array that would be easy to create as well, but recursion is not needed either way).

    3. COso what exactly is the question, it seems as though you have all of the logic there? Just store the number in an array that is at a higher scope level than your function and call generateNum(min,max); right afterwards.

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.
