I purchased a script online that's no longer supported and I just need one last functionality to finish off my project. One detail the client needs is to have a line of text link to another page in the site.
I do not know a whole lot about xml, but I understand it doesn't support html to include hyperlinks.
This is a quiz where users must answer specific questions in order to move on to the next step. It's fed into a div by a js file, I think, but I don't understand how it works. I'm not going to post any code just yet as I'm just reaching out for some advice right now and if what I want to do is even possible.
Is there some kind of a workaround? I've Googled plenty of sites with code chunks and have done a lot of experimenting, but I mostly just break the page the xml displays on.
Thanks.
Dont use the actual xml syntax of tags like <a></a>. Better replace these with other symbols like [a][/a]. When you output the code, simply replace [ and ] with < and >
You replace code before you put it into a div could look like this:
xmlAsString.replace(/\[/g,"<").replace(/\]/g,">");
edit:
I totally forgot about CDATA.
Forget my previous answer. Just add the <![CDATA[...]]> Tag around the anchor in your XML:
<![CDATA[link]]>

What I Want: Very simply I have a C program that generates a variable periodically, I want to be able to display this value on a website.
Restrictions: The webpage is HTML, php does not work, javascript does [I have tried a few javascript solutions but they have all been long, tedious and in the end ineffective] I want it to be able to format the text so that it matches the rest of the webpage. Above all I'd really like to find something simple that works.
Freedoms: I can output the variable from my C program to just about any file type and content that I want, the file is hosted so is available locally to the server or online for the client.
Preferred Solutions: I am currently playing around with the object and iframe tags native to html. They give a nice simple input:
<object height=20 width=75 type='text/plain' border=0 data="URL/filename.txt"></object>
inserts the contents of my file, but it can't be formatted so I am stuck with 12pt Courier font which is not acceptable. Using
<iframe seamless height=20 width=75 scrolling='no' src="URL/filename.htm"></iframe>
and adding my desired font/colour/size etc to the htm file gets me the right text style, but htm has a large amount of white padding around it which I can't seem to get rid of so I have to make my iframe quite large for the text to be displayed, but then it doesn't fit smoothly with other text.
So anyone that can answer one of four questions:
How to remove excess padding from htm
How to format the style of a html object
Is there anything in Java as simple as the php [so apparently it doesn't show php code even when you quote it as code. But basically using echo and get_file_contents to insert the contents of a txt file into a html page]
Propose an alternate solution
Padding and style can be handled by css.
By java I assume you mean javascript - google-ing will help you. Without details of what your server is running and what is dispatching your pages we can't give you an exact answer. You might want something with ajax to keep it updating in the background.
Try googling your question, you'd be surprised how often this helps.
I'm not sure what you're trying to do once you get the variable into your web page, but I think something like the following could be useful.
Create a hidden div on your page
Have your C application write the variable to some file
Use jquery to execute an ajax call to pull that value into the div ( or whatever other container you want to use
using some type of timer, execute the ajax call every X period of time, which will then get your up to date variable
on your main page, have another timer that will then come in to that container, grab your value and then you are free to do what you want with it.
This is all off the top of my head without knowing much about what you're trying to accomplish. If you provide some further details we may be able to help you a little more.
You need AJAX... that's just a fancy buzz-word. It means you can tell JavaScript can get a file from the server without reloading the page and you can insert data from that file into your HTML.
AJAX is made much simpler by using a JavaScript library like jQuery, but it can be done without jQuery. There's a pretty decent Getting Started tutorial at Mozilla Developer Network if you want to do it the hard way, but I really recommend jQuery.
As far as formatting... any formatting... you need to use CSS. Just about everything about the appearance of anything on a web page is controlled by CSS. MDN has a Learn CSS section, too.
load jquery on you main html file
put a div with some id (example id="newvalue")
make you c program to write the output in a file (for example value.html)
on main html page header, after jquery include code add some javascript like
$( document ).ready(function() {
$("#newvalue").load('yoursiteurl/value.html');
});
On my site, I collect information on items in a game I play. I would like to implement some sort of custom search for the items that is both easier to use, and displays the result in a more aesthetic manner.
Currently, I use a wikidot site which allows tags to be assigned to pages and they can be searched, but searching multiple tags doesn't work as I would like. It will start the list with pages with all the tags, then pages that have one of the tags, and finally pages that just happen to have the tags in the body. Also, the results are presented as the page title, the first few lines of text from each page (without any line breaks making it hard to read), and finish with a link to the page. [See example: http://imgur.com/a/gyTtD#0 ] What I would like for the results are something like the following: http://imgur.com/a/gyTtD#1, which is an actual page from my site, but it's not dynamic, I must edit that page if I want to keep it up to date; and for any permutations of tags I want to create a page like that for, I need to first find all of the relevant items, organize them how I want, then make the page containing the includes for each of their individual pages (each item has its own page, I just put an [[include item-name]] wherever I want that item to show up on other pages, which just puts the body of the page in.
What I'm looking for is the best plan of action to make this happen. I'm familiar with HTML/CSS/JS, but not much other webdev related stuff. Is there a way I could have a page with a comma separated list that I could parse with JavaScript to search pages? Or if should I look elsewhere, what are some good tutorials or quality sources to read up on how to do this?
Thank you in advanced for any answers you can provide.
If you still require help with this, I'd suggest asking on the Wikidot community wiki instead, as there are more people able to help you with your question there (as you have a Wikidot site).

I want to know if there is some way to create an independent HTML block .
For more explanation :
My problem is that I have a webpage in which I allow some users can add content (may contain HTML & CSS )
I allow them to add their content inside a certain block , but sometimes their content may not be clean code , and may contain some DIVS with no end , Or even some DIV end with no starting DIV
This sometimes distort my page completely
Is there any way to make their content displayed independently from my parent div , so that my div is first displayed well , and then the content inside it is displayed ?
I'm sorry for long message .
Thanks for any trial to help
sometimes their content may not be clean code , and may contain some
DIVS with no end , Or even some DIV end with no starting DIV This
sometimes distort my page completely
The easiest solution for you is going to be to add the submitted content to your page inside an <iframe>. That way, it doesn't matter if the submitted HTML is invalid.
If you have to worry about users possibly submitting malicious content (such as JavaScript), the problem becomes much harder: you need to sanitize the HTML. I can't tell you how to do this without knowing what server-side language you're using.

If that is the problem you are trying to solve, then having some markup to say a chunk of code was independent wouldn't help: They might include the "End of independent section" code in the HTML.
If you want to put the code in a page, you need to parse it, sanitise it (using a whitelist) to remove anything potentially harmful and then generate clean markup from the DOM.
you could use Static iframes.
check this out http://www.samisite.com/test-csb2nf/id43.htm
The safest way is to restrict the tags they can submit, and validate/sanitize those that they do, similar to the way we can use markup on here.
Having unchecked HTML injected into your page is asking for trouble.
Failing that, good old iframe will do the trick.
Okay, i belive there is something you can do, but it can require some time. You can use a parser to go through the users html, and get the tags and their content, and recreate the html making it clean.
But, as there are a lot of tags that can be used, or even invented tags, than you can limit the tags that the user are able to use in their html. You put a legend with the acceptable tags.
There are some pretty good html parsers for php, but they may break for some very bad html code, so this is why i suggest you just recreate it based on the parsing with a limited subset of acceptable tags.
I know it's a difficult/time consuming solution, but this is what i have in mind
I'm creating a webform that has combos containing 100 values or so. The values are the same.
The form may have several records. So if there are 100 records there are 10,000 lines which seems pretty wrong from a "download" point of view.
The thing is: I want to keep that combo dynamic to keep the id from the database.
So I came up to the following:
.....
<script>
stupidCombo = "<option>a"+
"<option>b"+
...
"<option>99zzz"+
"</select>";
</script>
..... form here
.... for each item in huge list do paint <table><tr> etc. etc
<td>
<select name="comb-<%=id%>">
<option selected><%=obj.val%>
<script>document.write(stupidCombo);</script>
</td>
... close form, table, html etc.
I have rendered it and "look" fine. The page has decreased from 50k lines to 5k and the select is created by the javascript on the client side.
My question is.....
Is this ok?
Is there any risk involved?
I borrow this Idea after understanding who most of the javascript frameworks work, but most of them work on a <div> element rather that just to the document it self.
I'm targeting IE6 and this is a quick fix that has to be on production tomorrow morning ( so I don't want to spend too much time on this ) but I don't want to have 50,000 lines written for each request if I can help it.
Thanks
HTTP compression (mod_gzip, etc.) will compress all that nicely.
If you insist on document.write, you will have to use JavaScript to write <select> element as well, because in HTML you're not allowed to put <script> inside <select>.
Another approach is to send one copy of the control to the browser and then duplicate it with help of selectElement.cloneNode(true).
HTML produced by document.write works in same way as normal one, so there is no any technical problems with your solution. ( of course, such solution works only if javascript enabled )
By the way, for the lists with big count of options, you can look at "suggest box" component, which can replace native selectbox.
well it obviously won't work if javascript is disabled.
Google does it ("document.write") all the time (Analytics/Adsense/...), so I don't see why there would be anything wrong with it.
Your solution does look a bit odd, because the <script> tag is inside a <select> tag, so you better check in several browsers. After all, you never know what IE is going to do :)
Update.
I've done just the way I asked and it worked fine. There were no problems with the js inside ie.
But...
Once the table is rendered, the next thing the user attempt to do ( always the user does something unexpected ) was..
"Ok, the report looks fine. I'm going to copy/paste it into MS-Excel thank you."
Which is something that I don't really care. Is up to the user, but the result was: The excel spreadsheet die ( or froze which is almost the same)!!!! because the javascript engine within the excel is not as good as it is inside IE, the combos took forever to copy and actually it leave excel application unusable.
I didn't knew the copy/paste was so good from IE to Excel that it actually copied all the generated html and Excel tried to run the javascript too with terrible results.
I'll try again by leaving the raw html and see if that works better.
:(
I am having issues with an Ebay template, if I try to upload it get's kicked back to me saying that it cannot contain javascript, I'm assuming that it's in the picture rollover option (mouseover pic enlarging tool) Any help would be greatly appreciated, I'm not real Java intuitive.
Just delete anything between the <script> and </script> tags. Or perhaps post the code snippet here so we can tell you what to remove.
The template should have a HTML file inside.
Search for ... parts and remove them as mentioned before.
Search for instances of onmouseover="...", onmouseout="..." and generally anything that looks like , removing the onsomeevent="dosomething" part.
