Invoking Javascript function from Struts 1.3

[Dennis Atkinson <de...@yahoo.com>]

Greetings all.

I have a problem invoking Javascript that I can't seem to solve.  I'm hoping someone here has run into the same kind of thing.
 
When I am iterating through a List of items to display (via the <logic:iterate> tag), one cell I am trying to write has to be a link to a Javascript function, with three parameters.  If I wasn't using Struts, I'd write standard html, like so:

<a href="javascript:showStuffForPerson('405574', '459', '3')">405574</a>

But if I do this in Struts, I get that exact string in the cell, which isn't what I want. I need to have 405574 in the cell, and when I click on it, the javascript has to be invoked with those three parameters.  It really, really needs to work this
 way.

I tried experimenting with the <html:link> tag, and it *seems* like that's the way to go, but I am lost with respect to the associated <html:param> tags.  I assume I'll need three of them (one for each parameter), but I can't seem to make that work.  If I give them a name, it doesn't work, and if I don't give them a name that doesn't work any better.

Or maybe I'm going about this all wrong?

Any assistance would be very much appreciated.

Thanks in advance,

Dennis

Not really. The whole point of the Struts tags is to access Struts
functionality, like action mappings. All this is is pure JavaScript. No
Struts. Accessing properties to use as parameters doesn't require the use of
a Struts link tag, because that's not what the Struts link tag is for.

Wth. That's precisely what I said.

Dave,

The OP wrote:

So I am going to assume that it does.

And, this seems like a perfectly reasonable thing to do.  If a company has existing functionality in javascript, they want to link to it.  It is illogical to expect them to rewrite their javascript stuff in Struts.  Or in anything else, for that matter.


Dennis,

We do the same thing here and it's not complicated to do.  I don't think you need to mess with the <html:link> tag.  Just create the tag normally, the same way as you would sans Struts, and use your beans to supply the values.

The three properties are prop1, prop2, prop3.


<logic:iterate id="listdata" name="theList"  
	type="putTheFullClassNameHere" scope="page">     
	<tr>
         		
    <td>
		<a href="javascript:showStuffForPerson(
				'<bean:write name="listdata" property="prop1"/>', 
				'<bean:write name="listdata" property="prop2"/>', 
				'<bean:write name="listdata" property="prop3"/>')">
			<bean:write name="listdata" property="prop1"/>
		</a>
   </td>


Have fun.

--Tom
