    <p>trying to create a simple slider for an input.</p> <p>Using a survey gem that adds extra fields. I added a class called "jSlider" to the question and does display the slider, but does not update the input.</p> <p>html form generated:</p> <pre><code>&lt;fieldset class="q_default jSlider" id="q_353" name="17) On a scale of 0 to 10, ..."&gt; &lt;legend&gt;&lt;span&gt;17) On a scale of 0 to 10, ...&lt;/span&gt;&lt;/legend&gt; &lt;ol&gt;&lt;span class='help'&gt;&lt;/span&gt; &lt;input id="r_18_question_id" name="r[18][question_id]" type="hidden" value="353" /&gt; &lt;input class="" id="r_18_answer_id" name="r[18][answer_id]" type="hidden" value="3840" /&gt; &lt;li class="string optional" id="r_18_string_value_input"&gt;&lt;input id="r_18_string_value" maxlength="255" name="r[18][string_value]" type="text" /&gt;&lt;/li&gt; &lt;/ol&gt; &lt;/fieldset&gt; </code></pre> <p>My js is:</p> <pre><code>$(".jSlider").each(function(){ var newSlider = '&lt;div style="margin-top:20px;margin-bottom:20px;" id="slider"&gt;0&lt;/div&gt;&lt;br /&gt;'; $(this).append(newSlider); $("#slider", this).slider({ value:0, min: 0, max: 10, step: 1, slide: function( event, ui ) { alert(ui.value); // when append, it adds to the fieldset // first parent is the fieldset, next should be the ol, then the li // finally arriving at the input field $(this).parent().next("ol").next("li").next("input:text").val(ui.value); } }); }); </code></pre> <h2>EDIT</h2> <p>Proposed edit to fix duplicate id breaks again.</p> <pre><code>$(".jSlider").each(function(){ var id = $(this).attr("id"); var sliderID = id + "_slider"; alert(sliderID); var newSlider = '&lt;div id="' + sliderID + '"&gt;&lt;/div&gt;&lt;br /&gt;'; $(this).append(newSlider); // or even // $(sliderID).slider({ $(sliderID, this).slider({ value:0, min: 0, max: 10, step: 1, change: function( event, ui ) { // alert(ui.value); // when append, it adds to the fieldset // first parent is the fieldset, next should be the ol, then the li // finally arriving at the input field $(this).closest('fieldset').find('input:text').val(ui.value); } }); }); </code></pre>

    3. CODoesn't matter. They are not allowed and will most likely break things. You need to fix your form generator if it uses the same ID twice. However, I was talking about the `<div id="slider">` which doesn't look generated...

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
