    <p>I have an svg with elements that I am binding to clicks and keyups. If the user edits a text field on the page, it updates the corresponding text element in the svg. And vice versa, if the user edits the svg, it updates the corresponding text field in the html. Using jQuery.</p> <p>A button on the page lets the user remove the svg from the DOM and add a different svg in its place (asynchronously). This new svg has the same elements as the first one, it just has a different graphical design.</p> <p>After loading this second svg, the bindings stop working. I reinitialize everything -- unbinding and rebinding -- by calling AB.init() below but still the user can't edit the svg. How do I fix this?</p> <p>UPDATE: all .bind()s are now .delegate()s per @Pointy's comment. However the problem persists. Is my .delegate() syntax valid for the namespace?</p> <pre><code>AB = { svgns: "http://www.w3.org/2000/svg" f: { field1: {svg:null, jq:null}, field2: {svg:null, jq:null} }, /* last activated text field */ active: undefined, init: function() { AB.f.field1.jq = $('#id_field_1'); AB.f.field2.jq = $('#id_field_2'); var svg_container = document.getElementById('svg_container'); var svg_text_elements = svg_container.getElementsByTagNameNS(svgns, 'text'); var length = svg_text_elements.length; for(var i=0; i &lt; length; i++) { var e = svg_text_elements[i]; if(e.id) { AB.set_svg_for_text_field(e); } else { var tspans = e.getElementsByTagName('tspan'); for(var j = 0; j &lt; tspans.length; j++) { var t = tspans[j]; AB.set_svg_for_text_field(t); } } } AB.delegate_and_display_text_fields(); }, delegate_and_display_text_fields: function() { a = []; $.each(AB.f, function(key, value) { if(value.svg &amp;&amp; value.jq){ $('form').delegate('input', 'keyup click', function() { value.svg.textContent = value.jq.val(); CB.set_active_element(key); CB.active = value; }); $('#svg_container svg').delegate('text', 'keyup click', function() { value.svg.textContent = value.jq.val(); CB.set_active_element(key); CB.active = value; }); if(value.jq.val()) { value.svg.textContent = value.jq.val(); } a.push(value); value.jq.parent().fadeIn(); } }); }, set_svg_for_text_field: function(e) { switch(e.id) { case "field_1": AB.f.field1.svg = e; break; case "field_2": AB.f.field2.svg = e; break; } }, ... </code></pre>

    2. COAnyway just look up jQuery's ".delegate()" method and use that to bind your event handlers.

    3. CO@Pointy I added the code that does the binding. Looking at .delegate() now...

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).
