    <p>I have a fairly simple web app built with Delphi (2009) Web Broker. I am trying (and failing) to output Javascript to the page.</p> <p>The javascript I need to output is in the body of the page in a <code>&lt;form&gt;</code> tag, and is as follows:</p> <pre><code>&lt;script&gt;DateInput('mydatefield', true, 'DD-MM-YYYY');&lt;/script&gt; </code></pre> <p>This javascript should create a nice date input control (tested ok in a hand-crafted HTML page). The code in my Delphi app this is:</p> <pre><code>Response.Content := Response.Content + '&lt;script&gt;DateInput(''mydatefield'', true, ''DD-MM-YYYY'');&lt;/script&gt;'; </code></pre> <p>The <em>Script</em> tags are being removed from the final output. </p> <p>As a test I added an HTML button with an <code>onClick</code> event set as follows:</p> <pre><code>Response.Content := Response.Content + '&lt;input type="button" onClick="alert(''Hello World'')" Value="Hello World"/&gt;'; </code></pre> <p>and when the source of the page is inspected </p> <pre><code>alert(''Hello World'') </code></pre> <p>had become </p> <pre><code>alert(&amp;#39;Hello World&amp;#39;) </code></pre> <p>I wondered if this translation of the single quote from ' into <code>&amp;#39</code>; might be causing my earlier script tag to be removed?</p> <p>Any help/pointers appreciated, thanks.</p> <p><em>*</em> EDIT</p> <p>I should point out that the Alert popup does work even with the <code>&amp;#39;</code> characters.</p> <p><em>*</em> EDIT</p> <p>I have tried to use JQuery scripts like $(document).ready( function() { etc }); and it's working, so I guess the problem is not with WebBroker output. Thanks to all who took time to read/think. </p>

    1. COI'm sorry I can't help you too much, however I think that it automatically escapes the single quotes, look at the various properties you can modify, also keep in mind that it's better to split javascript form the html, meaning that in stead of alert('hello world'); you might want to call a function called doHelloWorld(); from a javascript file, otherwise huge head aches can come your way(been there many times). I hope this helps at least a bit.

    2. COThanks @Dorin - problem is the javascript I need is the "DateInput" which has to be placed within the form element, and already calls the function DateInput with params which I have to dynamically create.

    3. COI would encourage you to have a look at DWScript http://code.google.com/p/dwscript/ and try to combine it with TIdHTTPServer and have a blast (: it's super easy and plesant, of course javascript or javascript libraries that you might/will use could give you some problems sometimes, but above all it's super plesant.

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).
