How to set Query value in WAD w. parameters

59 Views

Hi

Is it possible to set the queryname in the dataprovider using javascript.

My scenario is that I want to fetch the queryname from the URL with the following javascript

I have the script:

function GetPara( name )

{

name = name.replace(/[\[]/,"
\[").replace(/[\]]/,"
\]");

var regexS = "[
?&]"name"=([^&#]*)";

var regex = new RegExp( regexS );

var results = regex.exec( window.location.href );

if( results == null )

return "";

else

return results[1];

}

And then I want to implement something like the following in the template

//First dataprovider (TAB_A_DP) initialization

<bi:QUERY_VIEW_DATA_PROVIDER name="TAB_A_DP" >

<bi:INITIAL_STATE type="CHOICE" value="QUERY" >

<bi:QUERY value="SCRIPT_FUNCTION">

<bi:SCRIPT_FUNCTION value="GetPara('TAB1')" />

</bi:QUERY>

</bi:INITIAL_STATE>

</bi:QUERY_VIEW_DATA_PROVIDER>

//SEcond dataprovider (TAB_B_DP) initialization

<bi:QUERY_VIEW_DATA_PROVIDER name="TAB_B_DP" >

<bi:INITIAL_STATE type="CHOICE" value="QUERY" >

<bi:QUERY value="SCRIPT_FUNCTION">

<bi:SCRIPT_FUNCTION value="GetPara('TAB2')" />

</bi:QUERY>

</bi:INITIAL_STATE>

</bi:QUERY_VIEW_DATA_PROVIDER>
