    <p>I am working on a project where I need to dynamically build up web content coming from different sources (same domain). All the main libraries and css are managed centrally but depending on a configuration I have to add pages (html and embedded JavaScript) as 'tab content'.</p> <p>My first approach was using iframes and it worked well besides the annoyance that I had some duplicte code (especially the header). I also had some issues with frame sizes but I could handle that in the end.</p> <p>Now of course I read that iframes are evil but almost all the alternatives I found were using php or something else server-side. Unfortunately my web server does not provide anything like that, so I came across jQuery's load function. My first attempt is satisfying but what unsettles me now is managing (global) variables (and functions). Because jQuery.load() simply inserts the code into the DOM I always need to be extremely careful about naming here. For example I usually have a function called init() which is included in the body for the onload-Event. But every other page will need one of those as well.</p> <p>The project is very likely to grow (maybe at some point even external developers will take part). I am now at a point where I have to decide which path to take and I am torn.</p> <p>So my Question: Even though iframes are evil, im my experience it is a lot easier and secure than inserting the code via jQuery (in this particular case). Oh, that was not a question... The question would be: Is there any way to encapsulate variables and functions into the content that I load with jQuery? Or might there be a better way of handling variables/functions in this case anyways.</p> <p>I am grateful for any suggestions.</p>

    1. COactually when using load() your main window will always be the "main" window. when loading html pieces with load(), make sure just to load certain divs (without all the html and head and body tags) and use callbacks instead. for instance, on your external html files, dont use any js at all, rather put all js in one file on index.html and depending on what content you load, fire that specific callback. thats what worked for me! :) might not be the best way, though

    2. COIs that page public available and is it required that the content you load is visible to the search engine and associated with the page it is shown on?

    3. CONo, the page will not be public. It will be service pages for a project on a plc which has this very simple web server. That is the reason why i do not have PHP or anything.

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.
