Reloading a component and passing variables to it

[Jim S]

Trying to reload a component, passing new parameters to it.

I have the following code based on this discussion:  https://groups.google.com/forum/#!searchin/web2py/reload$20component/web2py/jZeJT0WFgV4/x4eeOpAFxh8J

    <script type="text/javascript">
        function priceListProductSiteEdit( priceListProductId ) {
            //alert(priceListProductId);
            //$('#priceListProductEdit2').load('/infocenter/pricing/priceListProduct.load?priceListProductId=' + priceListProductId);
            web2py_component("{{=URL('pricing', 'priceListProduct.load', vars="{'priceListProductId':" + priceListProductId + "})}}, target='priceListProductEdit');
        }
    </script>

But, when my controller function is called, the value passed to the priceListProductId variable is      + priceListProductId +     not the value that is passed to the javascript function.

I'm having a total brain-fart trying to figure out how to pass this properly.

Can someone help please?

Hello Jim,

what's in priceListProductId ?

I would see this in javascript :

priceListProductId = {{=request.vars.priceListProductId}}

?

priceListProductId is an integer that is being passed into the javascript function.  However, I don't know how to specify that on the web2py_component call.  Trying to pass it to the 'vars' parameter but can't get the syntax right.  It isn't in the request object in web2py yet.

For example, when I call the reload using this method, it works:

$('#priceListProductEdit2').load('/infocenter/pricing/priceListProduct.load?priceListProductId=' + priceListProductId);

But am having trouble getting the javascript variable passed to the URL function call.

I don't think it possible to pass javascript variable to web2py like that, it would be a big security hole if you can...

Not sure how it applies, but when I want to pass vars to component I just call or redirect to URL with the appropriate vars that I want to pass to the component from the master view/controller (the one in which there is component embeded)...

Then, my component just have to pickup the vars with request.vars.var with LOAD()... This can be does also with web2py_component() in javascript as show above...

But maybe you have a different requirement that I don't understand because you don't explained you use case nor showed code...

Thanks Richard.  Something you said in there triggered something for me and I think I know what to do now.

Thanks

Will post the solution once I find it.

Remember, everything inside {{...}} is rendered on the server before delivery to the browser, so you can't include JS in there. Instead, should be:

web2py_component("{{=URL('pricing', 'priceListProduct.load')}}" +
                 "?priceListProductId=" + priceListProductId,
                 target='priceListProductEdit')

You have to add the query string entirely in JS, so you can't use the web2py URL() function for that part.

Of course that is the answer Anthony!

For some reason I just wasn't able to come up with it today.  Thanks for laying things out clearly, as you always do.

Very much appreciated.

All the best
