help on c:load

11 September, 2007 - 13:35 — burger.lj

Hi,

I want to make a button load a script from a server and process the returned data.
i cannot seem to make the c:load command work properly.

i tried the javascript version: bb.command.load, but i cannot find the order in which i need to put the arguments (Is there a backbase IDE?).

Could you help me out by giving me an example of both implementations?

Thanks,

Lesley

Sure, please take a look at

Sure, please take a look at the code below.

inside your index.html:

<div>
<p>
 <e:handler event="click">
   <c:load url="foo.xml" method="GET" destination="." mode="replace"/>
 </e:handler>
 Load data with XEL
</p>
                       
<p>
 <e:handler event="click" type="application/javascript">
   bb.command.load("foo.xml","GET",'','',this,'replace');
 </e:handler>
 Load data with JS
</p>
</div>

and the foo.xml could look like:

<?xml version="1.0" encoding="UTF-8"?>
<div xmlns="http://www.w3.org/1999/xhtml">
        <span style="border:1px solid red;">hi</span>
</div>

With regard to the API, please take a look at the CHM file. The CHM file contains a full list of which arguments to pass for each command.

Another example

There's a little bit of rails in this example, but here is how I'm using c:load to update another element when a treeBranch element is clicked. HTH.

<b:treeBranch label="<%=h t %>">
  <e:handler type="text/xml" event="click">
    <c:hide with="[id('contenttarget')]" />
    <c:load url="/proggies/gridlist"
            data="name=<%=h t %>"
            mode="replaceChildren"
            destination="id('contenttarget')"
            type="text/xml" />
    <c:show with="[id('contenttarget')]" />
  </e:handler>
</b:treeBranch>

What would this look like

Hi buford,

Thanks for your reply. I am still stuck though. What would this look like when the data is a variable with xml in it? Because i want to send the xml.

i got this:

data="{$var}"

is this correct?

Thanks in advance,

Lesley

I want to post the entire variable as a string

24 September, 2007 - 11:23 — burger.lj

Hi buford,

I want to post the entire variable as a string. adding string() does not seem to work on the entire variable. Is there a way to transform the xml to string?

Thanks in advance,

Lesley

bb.xml.serialize(element, childrenOnly)

25 September, 2007 - 08:48 — Richard

To convert XML into a string, you can use the function bb.xml.serialize
If you want to exclude the top element itself and just serialize the children of the root element of the variable, set the second parameter to true.

So if your variable is called $myVar:

var sData = bb.xml.serialize(myVar, false);
bb.command.load(sUrl, 'POST', sData, null, oDest);

Almost there

Hi Richard,

Thanks for your reply. I think this might be it.
The only problem now is that the load does not send the xml-string, but probably the object-data-string

I have this variable:

<e:variable name="var" scope="global">
<e:data type="text/plain">
<a>
<b>
<c>c</c>
<d>d</d>
<e>e</e>
</b>
</a>
</e:data>
</e:variable>

and this should be sent:

<a>
<b>
<c>c</c>
<d>d</d>
<e>e</e>
</b>
</a>

Do you have an idea how to do this?

Thanks,

Lesley

CDATA is your friend

26 September, 2007 - 02:46 — Richard

Although the type is "text/plain", what looks like XML inside the e:data element is resolved to plain text: '\nc\nd\ne\n' where the \n is a newline.

If you instead wrap the faux-XML in CDATA tags, there is no evaluation or modificaton. Its exactly what you want it to be.

<e:variable name="var" scope="global">
<e:data type="text/plain"><![CDATA[
<a>
<b>
<c>c</c>
<d>d</d>
<e>e</e>
</b>
</a>
]]></e:data>
</e:variable>

Hi Richard, Thanks for your

26 September, 2007 - 12:24 — burger.lj

Hi Richard,

Thanks for your reply. Your solution works. Unfortunately for me the receiving end needs xml and not a string. I found this out because if it needed a string it would work. After installing a packet analyzer, i found out it needs real XML.

I am opening a new thread for this because this has nothing to do with c:load anymore.

Thanks again,

Lesley

bb.command.load works

27 September, 2007 - 10:15 — burger.lj

Hi Richard,

Thanks for your reply. I got it working now. I used to use c:load, but with bb.command.load it sends the xml as xml.

Hy,I have an application

23 October, 2007 - 14:05 — tomlux

Hy,

I have an application which send the resulted HTML code back for showing up.
I'm replacing by a Javascript the div-content by the returned HTML code.

How can I make this?

I have tried with bb.command.load and bb.command.create.

No results.

Here an example:

<script type="text/javascript">
  var result = "<b:button>ClickMe<b:button>";
  bb.command.create(bb.string.escapeXml(result),bb.getElementById('myDiv'),'firstChild');  </script>

Thanks,
Tom
