The Minibrowser allows the usage of variables. The var callback returns the corresponding value for the given variable.


There are two ways to initialize a variable:

  1. By adding it to the URL when calling the Minibrowser page. Example: http://link_to_the_minibrowser_code.xml#var:myvar=somevalue

  2. By checking if the variable is empty and, if yes, refresh the page via mb_nop with the variable as parameter:

    <If condition="$(empty:$(var:myvar))">
	<fetch mil="1">phone://mb_nop#var:myvar=somevalue</fetch>
</If>


Example 1: simple variable initialization

<?xml version="1.0" encoding="UTF-8"?>
<SnomIPPhoneText id="text">
	<If condition="$(empty:$(var:myvar))">
		<fetch mil="1">phone://mb_nop#var:myvar=somevalue</fetch>
	</If>
    <Text>Variable is $(var:myvar)</Text>
</SnomIPPhoneText>

Result when the variable value was added to the Minibrowser URL (URL called: http://10.110.16.61/xml/minibrowser/tests.xml#var:myvar=whatever)

Result when the variable value was not added to the Minibrowser URL (URL called: http://10.110.16.61/xml/minibrowser/tests.xml)


Example 2: Show the variable first_page before and after a value is assigned to it. The value of the callback will only last until the minibrowser is closed.

<?xml version="1.0" encoding="UTF-8"?>
<SnomIPPhoneBatch>
    <SnomIPPhoneText id="page0">
        <Title>page 0</Title>
        <SoftKeyItem>
            <Name>*</Name>
            <Url>http://link_to_this_example.xml#sub=*[@id="page1"]</Url>
        </SoftKeyItem>
        <Text>
            var:first_page: $(var:first_page)
            <br />
            Press * to continue
        </Text>
    </SnomIPPhoneText>
    <SnomIPPhoneText id="page1">
        <Title>page 1</Title>
        <SoftKeyItem>
            <Name>*</Name>
            <Url>http://link_to_this_example.xml#sub=*[@id="page2"]&amp;var:first_page=$(urlencode:hello world)</Url>
        </SoftKeyItem>
        <Text>
            Pressing * will set variable 'var_first_page' to value 'hello_world'
            <br />
            Press * to continue
        </Text>
    </SnomIPPhoneText>
    <SnomIPPhoneText id="page2">
        <Title>page 2</Title>
        <SoftKeyItem>
            <Name>*</Name>
            <Url>http://link_to_this_example.xml#sub=*[@id="page0"]</Url>
        </SoftKeyItem>
        <Text>
            var:first_page: $(var:first_page) <br />
	        Press * to continue to Page0
        </Text>
    </SnomIPPhoneText>
