    <p>I am trying to <em>eliminate the "enter event" default value</em> on <code>type=text</code>, which triggers submit on the form. I do so with the following:</p> <pre><code>var onEnter = function(values){ $("#"+values['id']).keydown(function(e){ if (e.which == 13) { event.preventDefault(); var function_to_call = window[values['function']]; if(typeof function_to_call === 'function'){ if(values['parameters']!= null){ parameters = values['parameters']; var args; if(typeof parameters === 'string') args = parameters.split(','); else args = new Array(parameters); function_to_call.apply(window, args); } else function_to_call(); } return false; } }); } </code></pre> <p>The code that matters for <em>taking away the default event</em> is </p> <pre><code>event.preventDefault(); return false; </code></pre> <p>The rest of code just calls a function with parameters or no parameters. The thing is, inside the functions called, there´s a condition that triggers an alert. Here´s the deal:</p> <ol> <li>If <strong>alert is not triggered</strong>, <code>[enter]</code> does not trigger form submission</li> <li>if <strong>alert is triggered</strong>, form submission is triggered</li> </ol> <p>The function called on every <code>type=text</code> is the same, and here is the alert condition:</p> <pre><code>...... if(!regex_match(item)){ alert("Solo son posibles los siguientes caracteres: '.' ',' 'a-z' 'a-Z' '0-9' y ' '"); return; } ..... var regex_match = function(text){ regex = /^[_., 0-9a-záéíóúñ]+$/i; return regex.test(text); } </code></pre> <p>Things tried:</p> <ul> <li>"<code>return false;</code>" after <code>alert(...)</code>; </li> </ul> <p>I am new to javascript, could anyone point out why this could be happening? Thanks in advance!</p>

    1. COYou say yourself that `return false` prevents form submission, but you don't have that with the alert. (`event.preventDefault()` should be enough, but from the question it's not clear if that's ever applied.)

    2. COPlease start from the beginning and EXPLAIN what the aim of the whole thing is. If you use the form to ajax stuff, REMOVE the submit button and return false in the submit event. If not, tell us more

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.
