This page shows you how you can easily integrate the charts with other external Javascript libraries. This particular example
|
||
|
|
adds a context menu to the chart, of which the only option is to show a login dialog. This could, for example, be used to
|
||
|
|
allow logging in to an admin area.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
The dialog doesn't need to require user input - it could just be a static "Please wait..." type dialog, which is shown while a
|
||
|
|
subsequent page loads that takes a few seconds.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
The ModalDialog was originally an external library, however it's now part of the OfficeExcel package. It's also covered by the
|
||
|
|
OfficeExcel license - so if you have an <a href="licensing.html">OfficeExcel license</a>, then the ModalDialog is part of that.

If you're interested in using this modal dialog, then you'll probably also want the CSS that styles it. This can be found in the
|
||
|
|
"css" directory.

<h3>Note about Microsoft Internet Explorer 8 and the ModalDialog</h3>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Microsoft Internet Explorer 8 only supports fixed positioning in strict rendering mode, therefore you must specify a DTD
|
||
|
|
when using this browser. Eg:
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<pre class="code">
|
||
|
|
<!DOCTYPE html >
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<a name="hiding"></a>
|
||
|
|
<h3>Hiding the ModalDialog</h3>
|
||
|
|
<p>
|
||
|
|
To hide the ModalDialog (from a "Cancel" button for example), you can use the Close() method:
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<pre class="code">
|
||
|
|
<input type="reset" value="Cancel" onclick="ModalDialog.Close()">
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<a name="customising"></a>
|
||
|
|
<h3>Customising the ModalDialog</h3>
|
||
|
|
<p>
|
||
|
|
You can customise the appearance of the ModalDialog by using three CSS classes, which are documented <a href="css.html">here</a>.
|
||
|
|
This page customises the dialog slightly by changing the shadow X/Y offsets:
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<pre class="code">
|
||
|
|
<style>
|
||
|
|
/*
|
||
|
|
* These are the CSS classes that you can use to customise the appearance of the ModalDialog. If you're trying to

}
|

<a name="integration"></a>
|
||
|
|
<h3>ModalDialog integration</h3>
|
||
|
|
<p>
|
||
|
|
To integrate the ModalDialog look at the sample code above (the key line is where the context menu is defined). The method you should call is <b>ModalDialog.Show(id, width)</b>.
|
||
|
|
The <i>id</i> is the <i>id</i> of the layer to use. Only the <i>.innerHTML</i> is used, not the layer itself, so it can be hidden by
|
||
|
|
setting the display CSS <i>display</i> property to <i>none</i>. The <i>width</i> is a number which is used as the width of the dialog.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
The only library needed for the ModalDialog to work is <i>OfficeExcel.modaldialog.js</i> - you do not need to use
|
||
|
|
<i>OfficeExcel.common.js</i>. This makes for far smaller download requirements.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<a name="covering"></a>
|
||
|
|
<h3>Covering the scroll bars</h3>
|
||
|
|
<p>
|
||
|
|
Normally, a regular DIV lives inside the browser and cannot cover the scroll bars. There is however a way to achieve
|
||
|
|
this but it does mean that restructuring your website may be necessary, and it's done by using an IFRAME. The following
|
||
|
|
steps are involved:
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li style="margin-top: 0">The index page of your website creates an IFRAME and sets it to cover the entire window.</li>
|
||
|
|
<li style="margin-top: 0">This IFRAME then loads the website.</li>
|
||
|
|
<li style="margin-top: 0">The DIV then covers the top-most window.</li></li>
|
||
|
|
</ol>
|
||
|
|
|
||
|
|
<p style="margin-bottom: 50px">
|
||
|
|
There is an example of this technique <a href="iframe-setup.html"><b>here</b></a>
|
||
|
|
