<p>in the following, I am using filter('input:text,textarea') to set input fields as read only, (and make them opaque). However, this selector is selecting only the text inputs, and not the textarea. What am I doing wrong?</p> <pre><code><!DOCTYPE html> <html> <head> <title>setReadOnly() Test</title> <link rel="stylesheet" type="text/css" href="../styles/core.css"> <link rel="stylesheet" type="text/css" href="test.setReadOnly.css"> <script type="text/javascript" src="../scripts/jquery-1.4.js"></script> <script type="text/javascript" src="../scripts/jqia2.support.js"></script> <script type="text/javascript"> (function($){ $.fn.setReadOnly = function(readonly) { return this.filter('input:text,textarea') .attr('readOnly',readonly) .css('opacity', readonly ? 0.5 : 1.0) .end(); }; })(jQuery); </script> <script type="text/javascript"> $(function(){ $('#sameAddressControl').click(function(){ var same = this.checked; $('#billAddress').val(same ? $('#shipAddress').val():''); $('#billCity').val(same ? $('#shipCity').val():''); $('#billState').val(same ? $('#shipState').val():''); $('#billZip').val(same ? $('#shipZip').val():''); $('#bill_random_field').val(same ? $('#ship_random_field').val():''); $('#billingAddress input').setReadOnly(same); }); }); </script> </head> <body> <div data-module="Test setReadOnly()"> <form name="testForm"> <div> <label>First name:</label> <input type="text" name="firstName" id="firstName"/> </div> <div> <label>Last name:</label> <input type="text" name="lastName" id="lastName"/> </div> <div id="shippingAddress"> <h2>Shipping address</h2> <div> <label>Street address:</label> <input type="text" name="shipAddress" id="shipAddress"/> </div> <div> <label>City, state, zip, random_field:</label> <input type="text" name="shipCity" id="shipCity"/> <input type="text" name="shipState" id="shipState"/> <input type="text" name="shipZip" id="shipZip"/> <textarea name="random_field" rows="2" cols="20" id="ship_random_field"></textarea> </div> </div> <div id="billingAddress"> <h2>Billing address</h2> <div> <input type="checkbox" id="sameAddressControl"/> Billing address is same as shipping address </div> <div> <label>Street address:</label> <input type="text" name="billAddress" id="billAddress"/> </div> <div> <label>City, state, zip, random_field:</label> <input type="text" name="billCity" id="billCity"/> <input type="text" name="billState" id="billState"/> <input type="text" name="billZip" id="billZip"/> <textarea name="random_field" rows="2" cols="20" id="bill_random_field"></textarea> </div> </div> </form> </div> </body> </html> </code></pre>

Guidance

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.
