Get Value From Query String

Definition:

NDLLibrary.getValueFromQuerystring(urlParamName)

Description:

Obtain the parameter values specified in the URL used to call the form, if any.

Parameters:

This function has one parameter:

urlParamName - Required

The name of the parameter whose value you want to retrieve. The name is case-sensitive.

Note: This function does not use the default ndlParams object.

Returns:

The value of the specified URL parameter.

Null if parameter not found.

Code Sample 1:

var urlParamName = "param1";

return NDLLibrary.getValueFromQuerystring(urlParamName);

Code Sample 2:

form1.page1.ndltextbox1.value = NDLLibrary.getValueFromQuerystring("param1");

Code Sample 3:

var customerName;

customerName = NDLLibrary.getValueFromQuerystring("param2");

Notes:

When calling a form you can include parameter values in the URL used to call the form, in the format:

?<parameter name>=<value>&<parameter name>=<value>...

If such parameters are included, you can use getValueFromQuerystring to retrieve the values in these parameters, one at a time.

Using as Predefined Action in Event:

When assigned to an Event as a predefined action, you will need to generate a JavaScript function and then edit the skeleton script to specify the parameter you want to retrieve. Edit the automatically generated code:

return NDLLibrary.getValueFromQuerystring(ndlParamsName);

so it matches the two lines shown in Code Sample 1 above, replacing param1 with the actual parameter name, leaving the double quotes around it.

Alternatively you can enter the parameter name directly in the original code, in place of ndlParams, e.g.:

return NDLLibrary.getValueFromQuerystring("param1");

Note that if you enter the name directly, it must be surrounded by double quotes.
