  1. PODisplay options in a drop-down based on what is selected in another drop-down
    text
    copied!<p>I want to display options in a drop down menu based on what is already selected in another drop down menu. I have 16 options in the first drop-down, so I want to show different options in the second drop down for each selection in the first. I would like to do this using javascript or jquery. </p> <p>Here is the first drop down in my html file: </p> <pre><code> &lt;div&gt; &lt;label for="failureReason"&gt;Failure Reason:&lt;/label&gt; &lt;select id="failureReason" data-theme="a" data-icon="arrow-d" data-iconpos="right"&gt; &lt;option value="1"&gt;Damage&lt;/option&gt; &lt;option value="9"&gt;Calibration Failure&lt;/option&gt; &lt;option value="5"&gt;Component Failure&lt;/option&gt; &lt;option value="93"&gt;Customer Request&lt;/option&gt; &lt;option value="5"&gt;Error on Potted SUT&lt;/option&gt; &lt;option value="41"&gt;Installation Error&lt;/option&gt; &lt;option value="6"&gt;Interference&lt;/option&gt; &lt;option value="46"&gt;Network Issue&lt;/option&gt; &lt;option value="3"&gt;No Fault Found&lt;/option&gt; &lt;option value="8"&gt;No Power/Fuse Blown&lt;/option&gt; &lt;option value="23"&gt;Non-AMCS Issue&lt;/option&gt; &lt;option value="49"&gt;OBC HW Issue&lt;/option&gt; &lt;option value="30"&gt;OBC SW Issue&lt;/option&gt; &lt;option value="2"&gt;Training Issue&lt;/option&gt; &lt;option value="68"&gt;Truck Not Available&lt;/option&gt; &lt;option value="51"&gt;Routine Maintenance&lt;/option&gt; &lt;/select&gt; &lt;!-- Put in options for failure reason --&gt; &lt;/div&gt; </code></pre> <p>And I want to display different options inside this drop-down depending on what has been selected for "Failure Reason": </p> <pre><code>&lt;div&gt; &lt;label for="solutionId"&gt;Solution Id:&lt;/label&gt; &lt;select id="solutionId" data-theme="a" data-icon="arrow-d" data-iconpos="right"&gt; &lt;option value="1"&gt;Repaired&lt;/option&gt; &lt;option value="2"&gt;Restarted&lt;/option&gt; &lt;option value="3"&gt;Reinstalled Software&lt;/option&gt; &lt;option value="4"&gt;Replaced Loadcell&lt;/option&gt; &lt;option value="5"&gt;Replaced SUT&lt;/option&gt; &lt;/select&gt; &lt;!-- Put in options for Solution Id --&gt; &lt;/div&gt; </code></pre> <p>I've seen other examples, but nothing like what i'm trying to achieve. I need to be able to get the "value" of whatever option is shown and chosen for use in other parts of my javascript file.</p> <p>EDIT: </p> <p>I realise my question is a bit confusing. I'll try to be more clear. If "damage" is selected for failure reason, I want to show:</p> <pre><code>&lt;div&gt; &lt;label for="solutionId"&gt;Solution Id:&lt;/label&gt; &lt;select id="solutionId" data-theme="a" data-icon="arrow-d" data-iconpos="right"&gt; &lt;option value="1"&gt;Repaired&lt;/option&gt; &lt;option value="3"&gt;Reinstalled Software&lt;/option&gt; &lt;option value="4"&gt;Replaced Loadcell&lt;/option&gt; &lt;/select&gt; &lt;!-- Put in options for Solution Id --&gt; &lt;/div&gt; </code></pre> <p>But if "calibration failure" is chosen, I want to show:</p> <pre><code>&lt;div&gt; &lt;label for="solutionId"&gt;Solution Id:&lt;/label&gt; &lt;select id="solutionId" data-theme="a" data-icon="arrow-d" data-iconpos="right"&gt; &lt;option value="1"&gt;Repaired&lt;/option&gt; &lt;option value="2"&gt;Restarted&lt;/option&gt; &lt;option value="5"&gt;Replaced SUT&lt;/option&gt; &lt;/select&gt; &lt;!-- Put in options for Solution Id --&gt; &lt;/div&gt; </code></pre>
