    <p>I have these 2 functions (serialize and deserialize) in Javascript (below) and I want to change it to jQuery. I am wondering what would the right replacement for read and write in jQuery. Read and write strings are from and to a Textarea. This is part of Openlayers vector formats, getting geometries into / from OL map canvas.</p> <p>Serialize is outputing the geometries from mapcanvas to textarea.</p> <pre><code>function serialize(feature) { var type = document.getElementById("formatType").value; var pretty = document.getElementById("prettyPrint").checked; var str = formats['out'][type].write(feature, pretty); str = str.replace(/,/g, ', '); document.getElementById('output').value = str; } </code></pre> <p>Deserialize is reading string from Textarea into OL mapcanvas.</p> <pre><code>function deserialize() { var element = document.getElementById('text'); var type = document.getElementById("formatType").value; var features = formats['in'][type].read(element.value); var bounds; if(features) { if(features.constructor != Array) { features = [features]; } for(var i=0; i&lt;features.length; ++i) { if (!bounds) { bounds = features[i].geometry.getBounds(); } else { bounds.extend(features[i].geometry.getBounds()); } } vectors.addFeatures(features); map.zoomToExtent(bounds); var plural = (features.length &gt; 1) ? 's' : ''; element.value = features.length + ' feature' + plural + ' added'; } else { element.value = 'Bad input ' + type; } } </code></pre> <p>Thanks in advance.</p> <p>Again, I am asking about the read and write function equivalent in jQuery. These 2 lines:</p> <pre><code>var str = formats['out'][type].write(feature, pretty); var features = formats['in'][type].read(element.value); </code></pre>

    1. COIf you are asking how to set/get the value of a textarea with ID="foo", you can use $('#foo').val('bar') to set, $('#foo').val() to get.

    2. CONo, I am not asking the DOM. I am asking about the read and write. Is there any equavalent function in jQuery? var str = formats['out'][type].write(feature, pretty); and these: var features = formats['in'][type].read(element.value);

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.
