    <p>I have built a function using jQuery to insert into a table a new row including some inputs, like textboxes, checkboxes and one button.</p> <p>This is the code I have:</p> <pre><code>$('#AddEntry').click(function () { var lastTrClass = $('tr:last').attr('class'); var textBoxTitle = '&lt;input id="titleid" type="text" value="" style="width: 100%; vertical-align: middle"&gt;'; var textBoxStartDate = '&lt;input id="StartDate" type="text" class="required DatePicker" value="" style="width: 100%; vertical-align: middle"&gt;'; var checkBoxSync = '&lt;input id="Sync" type="checkbox" checked="checked" disabled="disabled" value="true" style="vertical-align: middle"&gt;'; var lastDate = '&lt;input id="LastSyncDate" class="required DatePicker" type="text" value="" style="width: 100%; vertical-align: middle"&gt;'; var buttonEdit = '&lt;button id="btnEditar" class="EditButton icon_only text_only" style="vertical-align: middle;" type="button"&gt;Editar&lt;/button&gt;'; if (lastTrClass == 'gradeA odd') { $('#DataTable &gt; tbody:last').append("&lt;tr class='gradeA even'&gt;&lt;td&gt;#&lt;/td&gt;&lt;td&gt;" + textBoxTitle + "&lt;/td&gt;&lt;td&gt;" + textBoxStartDate + "&lt;/td&gt;&lt;td&gt;" + checkBoxSync + "&lt;/td&gt;&lt;td&gt;" + lastDate + "&lt;/td&gt;&lt;td&gt;" + buttonEdit + "&lt;/td&gt;&lt;/tr&gt;"); } else { $('#DataTable &gt; tbody:last').append("&lt;tr class='gradeA odd'&gt;&lt;td&gt;#&lt;/td&gt;&lt;td&gt;" + textBoxTitle + "&lt;/td&gt;&lt;td&gt;" + textBoxStartDate + "&lt;/td&gt;&lt;td&gt;" + checkBoxSync + "&lt;/td&gt;&lt;td&gt;" + lastDate + "&lt;/td&gt;&lt;td&gt;" + buttonEdit + "&lt;/td&gt;&lt;/tr&gt;"); } }) </code></pre> <p>As you can see in my code, I'm generating the inputs into a <code>var</code>, but my question is whether or not this is safe. Is my code vulnerable to a JS injection or something like that? Is there a better way to do this? </p>

    1. COIt's as safe as any other way of appending elements to the DOM.

    2. COthe "var" in your code are only scoped in the function and are private.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
