pass get args from page to webscript

Hello! I have a page with several webscripts on it.<?xml version="1.0" encoding="UTF-8" standalone="no"?><page> <id>scans</id> <title>Сканы</title> <template-instance>scans</template-instance> <authentication>none</authentication>

Hi,

You should be able to access the request parameters in both the WebScript JavaScript controller and FreeMarker template by using "page.url.args" e.g. for your example parameters you can use:

page.url.args.tag‍

And you can iterate over all the request parameters in the FreeMarker template as follows:

<#list page.url.args?keys as key>
   ${key} = ${page.url.args[key]}
</#list>‍‍‍

It won't be possible to prevent them from being available to all WebScripts within the page as they are specific to the page. Is there any particular reason why you don't want one of the WebScripts to have access to the request parameters?

Regards,
Dave

Hi, viru.

It is possible if both webscripts use the "args" object (rather than page.url.args to get their properties/parameters).
Then you can make use the following config where you explicitly bind in the property to only one of the webscripts.

<page> 
   <id>scans</id>
   <title>Сканы</title>
   <template-instance>scans</template-instance>
   <authentication>none</authentication>
   <components>
        <component>
            <region-id>center</region-id>
            <url>/scans/upload</url>
            <properties>
               <tag>{tag}</tag>
            </properties>
        </component>
        <component>
            <region-id>listbox</region-id>
            <url>/scans/list</url>
        </component>
    </components>
</page>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

upload.get.js


var tag = args.tag;
‍‍‍

upload.get.html.ftl

${args.tag}‍

Try to always use the "args" object in your webscripts since that approach gives you full control of your webscript's parameters.
