    <p>I need to validate my textbox using JavaScript, so far i made this :</p> <pre><code>$(document).ready(function(){ $('#search_form').validate({ rules: { searchText:{ required: true, number: true }, }, messages: { searchText: { required: "required", number: "must be a number" }} })} ); </code></pre> <p>it works fine but i also need to show a message if user presses the search button without enter any value, and of course the textbox is containing the message "please enter your number" (using placeholder).</p> <p>the serach form :</p> <pre><code>&lt;form method="get" id="search_form"&gt; &lt;input type="button" value="search" id="search" /&gt; &lt;input type="text" name="searchText" id="searchText" placeholder="please enter your number" /&gt; &lt;/form&gt; </code></pre> <p>the current code doesn't show anything <strong>if user presses search button</strong> without inserting a number, but if he inserts letters for example he will get the message "must be number" and if he deletes any value was there in textbox, he will get the message "required".</p> <p>i tried : </p> <pre><code>searchText:{ required: { depends: function() { return $( "#searchText" ).val() == 'please enter your number '} }, number: true }, </code></pre> <p>but nothing changes.</p> <p>i hope i could explain my question good.</p> <hr> <p>Thanks!</p> <p>you are right it works fine if i delete whatever value in the textbox i get required msg. but since i made the validation on the form, it didn't response on the button clocking. how i can add a validation on the button too ? </p>

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.
